Timing chain marks on a 4t Chinese 50cc scooter

The ignition system plays an important role: without it, not a single vehicle with a gasoline or diesel engine will move. The quality of engine operation, whether it will start in cold weather, and whether it will work correctly depends on how it is configured. Depending on how the ignition is set and what spark plugs are selected on the scooter, it depends on whether it will go or not. From this material you will learn how to set the ignition on a scooter yourself, what you will need for this, and how to set up a contactless system.

We adjust the contactless ignition system

The contactless system operates through a sensor, switch, primary and secondary ignition windings. When the rotor with magnet closes the sensor, it sends a signal to the commutator, which, in turn, begins to accumulate current from the generator and transmit it to the primary winding. At this moment, high voltage appears in the secondary ignition winding. Its purpose is to ignite the spark. If there are any malfunctions listed above, adjustment is carried out by simply aligning the crankcase and ignition marks; to do this, remove the valve cover. The next steps are:

We disassemble the crankcase in accordance with the technical description for your car.
A mark is made on the rotor and crankcase at the dead center position of the engine in a place convenient for viewing.
By rotating the crankshaft, we achieve a spark, make a mark on the crankcase relative to the mark made on it in the MTD. The difference between these marks on the crankcase is the ignition timing.
Unclench the stator mounting bolts and set the advance angle corresponding to the technical documentation.

It is important to ensure that two of the three holes in the gear for the chain are at the level of the cylinder, and the remaining one is above the plane in which the cylinder and the mentioned holes are located

Each type of vehicle requires you to approach and work with parts differently, so bring the service manual to the garage. If suddenly all the machinations did not help, and you are sure that the remaining units are in good working order, you should replace the switch, since it cannot be repaired and is inexpensive.

Main elements of the system

Of course, the first thing to mention is the spark plugs. They are installed in the cylinder head, the electrodes come out from the inside. These are the elements that allow the air-fuel mixture to ignite. But with the help of spark plugs alone, the engine will not be able to run. It is necessary to monitor the position of the crankshaft in order to know in what position the pistons are in the cylinders.

For this purpose, an inductive sensor operating on the Hall effect is used. It is part of the design of another element - the ignition distributor. The sensor produces a pulse that is sent to the switch. This device allows you to amplify a weak signal to a voltage of 12 volts, and then apply it to a coil. A coil is nothing more than a simple transformer (step-up). Its secondary winding has a greater number of turns than the primary. Due to this, the voltage increases and the current decreases. The voltage in the BSZ is supplied to the spark plugs at a value of 30-35 kV (depending on the car model).

Broken ignition as a cause of engine failure

How to set the ignition on a VAZ 2106
First of all, I would like to talk about what can cause a four-stroke scooter engine to fail, and whether an unadjusted ignition should be blamed for this. Answering this question, we can answer with one hundred percent confidence that an incorrectly configured or simply faulty ignition may well become the cause of engine failure. However, it is too early to blame everything on a faulty ignition system until you check the main parts that affect the performance of the engine. Let's talk about them in more detail.

The first and perhaps most obvious is a lack of fuel or a clogged carburetor. Before you start trying to adjust the ignition, thoroughly clean the carburetor and make sure that fuel is flowing to the engine. Also, check that the carburetor is providing sufficient air supply.

The second, most common reason why an engine refuses to start is faulty spark plugs. Make sure that the spark plugs used in the scooter are not punctured and have a good enough spark. Simply replacing the spark plugs usually helps.

If you are completely convinced that there are no more reasons for the engine not to start, then you can dig deeper and look for the problem in an incorrectly configured ignition. Let's figure out how to set the ignition on a scooter.

Results

The absence of a spark when power is supplied to the coil requires checking the high-voltage circuit and ground.
If the high-voltage circuit and ground are fully operational, then the problem is most likely with the coil itself.
If there is no voltage at the coil terminals, measurements are taken on the switch.
If there is voltage at the switch terminals and there is no voltage at the coil terminals, the reason is most likely that there is no ground on the coil or the wire connecting the coil and the switch is broken - the break must be found and repaired.
The absence of voltage on the switch indicates a malfunction of the generator, the switch itself, or the induction sensor of the generator.

The method for checking the CDI ignition system coil can be used not only for motorcycles, but also for any other vehicles. The diagnostic process is simple and consists of a step-by-step check of all parts of the ignition system to determine the specific causes of problems. Finding them is quite simple if you have the necessary knowledge about the structure and operating principle of the CDI ignition.

What is ignition and how does it work?

How to set Electronic Ignition on Mt

So, let's start getting answers. The ignition system in a scooter is responsible for the correct operation of its engine and the appropriate moment of ignition of the mixture of fuel and air. The required proportions of these components are provided in the carburetor, and then the combustible composition enters the cylinder. At the moment of the highest degree of compression, a spark is supplied to the spark plug, which ignites the mixture. The spark voltage in some engines reaches 40 thousand volts.

The ignition system of a scooter is responsible for ensuring all this; it has a similar principle of operation in a moped, walk-behind tractor and any other mechanical vehicle with a gasoline engine. The result of its correct operation are such characteristics as a quick increase in engine speed, the usual level of exhaust gases emitted from the pipe and the absence of suspicious pops.

If suddenly, after repairs, you sit on your own “iron horse”, and for some reason it no longer gallops with the agility inherent in it, it’s worth checking the spark plugs. They must have a light brown soot. If the spark plugs have a black, tarry, thick layer, this is not a good symbol; in general, any deviation from the norm may be evidence of a malfunction of the ignition system.

Read

A sure sign of a poorly adjusted mechanism is also a slow increase in engine speed, exhaust pipe shots, and excessive smoke density.

While driving, you may experience jerking and uneven acceleration when accelerating. Any one of these signs or a composition of several is a direct indicator of a malfunction of the ignition system; in most cases, this problem is solved by adjusting it.

The principle of operation of ignition in a 4-stroke scooter engine

Modern scooters are equipped with contactless systems. They are considered the most reliable and easy to use, do not require complex connections, and provide a constant good spark on time. However, the setting is still important; even the presence of a spark does not always allow the fuel mixture to ignite, since its power also plays a role.

The main reasons for the operation of the ignition system are quite simple: its task is to create a spark to detonate the fuel mixture. If this does not happen, you need to carefully examine each node and find out why the spark disappeared.

In order to check whether there is a spark at all, you need to unscrew the spark plug and apply it to the engine ground; this can be done using metal objects that are not covered with paint. You cannot hold it with your hand: if there is a spark, it can give you an electric shock, and the discharge reaches 40,000 volts, which the coil creates.

Broken ignition is the cause of engine failure

An incorrectly configured or faulty ignition often causes engine failure. It would be wrong to immediately climb into the cylinder and examine the insides of the scooter, especially since this will not solve the problem. Before touching the ignition system, you need to check for other reasons why the scooter may not work.

The simplest thing is the lack of gasoline in the tank. Quite often, owners forget to refuel their vehicle, and such a trivial reason can be overlooked.
The carburetor may be clogged, which prevents the formation of a mixture suitable for driving.
The carburetor needs to be cleaned regularly, so it doesn't hurt to check whether fuel is flowing from it into the cylinder. It is possible that the fuel pipe is clogged. The jets and other parts of the device may become clogged with debris, which causes little fuel to flow or, conversely, the engine does not have enough air, and therefore it does not start.
The scooter may also refuse to start if the fault is caused by spark plugs. They may be wet or not produce a normal spark. It is advisable to have a spare set and check with it. In any case, the spark plug needs to be unscrewed and inspected.

Connecting the switch

Cases vary, it is possible that you will have to change the wiring

Therefore, you will need to take into account the purpose of all pins on the switch plug. This will allow the connection to be made correctly, and there will be no risk of damaging it

The first pin of the switch is the output. In other words, the amplified signal is removed from it. It must be connected to the terminal of the “K” coil. The second contact is connected to ground - the negative of the battery.

All three wires from the Hall sensor go to the VAZ switch. Moreover, the signal wire is connected to the sixth terminal of the switch. The fifth is the power output (the voltage on it is stable 12 Volts). The third output of the switch is ground (minus power). The third is connected inside the block to the second. But between the fourth, which is supplied with power from the battery, and the fifth there is a constant resistance and a voltage stabilizer.

Notes

Experienced repair technicians for devices such as mopeds explain the frequent ignition failure of these devices as follows. Even at the manufacturer’s factory, the moped is equipped with a late ignition, which results in incredibly sluggish ignition response to the accelerator handle and accumulating carbon deposits on the spark plug.

Therefore, it is important to know the method of how to set the engine to start in order to independently bring it back to life

Operating a scooter and enjoying its ownership brings a lot of positive emotions to the owner. In general, a scooter is a truly unique motor scooter, which is an almost universal transport. The scooter is great for driving around the city and for traveling outside of it. And everything would be fine, but sooner or later the moment comes when it has to be repaired and maintained, something that motorcyclists like to do much less of. Also, you often have to adjust and set the ignition, which few people know how to do correctly. It’s exactly how to set the ignition on a scooter that will be discussed in today’s article.

How to set the ignition on a scooter

With minimal experience, but good theoretical knowledge, you can set the ignition yourself. To do this, you just need to strictly follow the instructions below.

The most important part of tuning is to find the correct position for the timing sprocket to sit. In order to find it, they use special marks that are applied at the factory when assembling the engine.

The desired mark looks like the letter "T". In this position, the piston is at dead center. This is the extreme position after which the piston will return back. You need to rotate the rotor until the protrusion on the crankcase and the letter “T” coincide. This can be done using your hands or a kick starter. An electric starter does not need to be used.

To adjust, you need to align the “T” mark and the protrusion on the engine crankcase

Labels may look different on different scooters

If the piston has only moved down minimally, turn it further until the marks line up. It's not always possible to get the right position the first time. After they match, you need to study the other marks: they are located on the timing star. Usually these are three points or holes that are located on the outside of the star. They form a triangular shape if you connect them visually

Notice that one point is larger than the others. After adjusting the ignition, it should be on top, and the other two marks should remain opposite each other

They must stand horizontally.

Markings on the timing star

If the ignition is contactless, it is adjusted as follows. In order for the engine to run smoothly and correctly, you need to adjust the ignition of the mixture at the right moment. To do this, after all the tags are installed in the right places, you need to understand how the contactless principle works in general.

A special feature of the BZS is the presence of special sensors, a switch, and two types of ignition coil winding. When the sensor is closed using a rotor equipped with a magnet, a pulse is generated that enters the commutator, it pumps up the current coming from the generator and directs it to the primary winding of the coil. After this, the charge enters the secondary winding, where a high voltage is generated, with the help of which a spark appears, used to detonate the gasoline mixture. Adjusting the ignition is the alignment of the marks on the crankcase and the star. Usually you have to remove the valve cover.

After this you need to do the following:

Labels are set in the manner described above.
In order to set the ignition angle, you can release the stator mount and adjust it in accordance with the technical requirements of your vehicle.
Make sure that the marks or holes are in the correct position.

Conclusion

Don't be afraid of the ignition system. It’s easy to set up, the main thing is to check the entire circuit; much more often the switch fails, there is no gasoline or the spark plug needs to be replaced. Only after making sure that there are no physical malfunctions should you start setting up the ignition. If it is set correctly, you will hear and notice, as the engine will start easily and run smoothly.

Often, scooter owners need to set the ignition. In this article we will talk about how to properly adjust the ignition and in what cases this procedure should be carried out.

So, what can indicate that the ignition on a scooter is not configured correctly? Typically, the following signs may indicate problems with ignition:

— The engine is trembling, that is, it is working unstably (extraneous uncharacteristic sounds are heard, vibration is felt, floating speed is noticeable at idle); — Popping noises are heard in the muffler; — Power drops; — The scooter smokes more than usual; — The engine does not pick up speed well.

If you observe one or more of these signs, then it is worth checking the operation of the ignition system. A good place to start is by checking the spark plug. As a rule, the appearance of the spark plug can shed light on the reasons for the engine's malfunction. You need to pay attention to the color of the end of the insulator that goes into the cylinder. During normal ignition operation, it has a sandy tint. If the end of the insulator is black, then this indicates that there is soot on it, and this is a reason to figure out whether everything is in order with the ignition.

Before taking a closer look at the process of setting the ignition, it is necessary to briefly touch upon the principle of operation of the ignition itself. Actually, unstable engine operation can be observed with premature and late ignition. With premature or early ignition, the fuel-air mixture is ignited by the spark plug at a time when the piston is not yet at top dead center. With late ignition, the fuel-air mixture is ignited when the piston is almost down, that is, the mixture ignites and passes through the exhaust rings of the cylinder, which leads to pops and smoke from the muffler. The optimal moment for ignition - ignition of the fuel-air mixture occurs at the moment the piston begins to move from the dead center down. This is a very specific figure, which is usually indicated in the scooter’s operating instructions. Typically, the amount of downward displacement of the piston at which the best ignition timing occurs is from 2 to 4 mm.

It is worth noting that there are two types of ignition - contact and non-contact. They all produce a spark, but their operating principles are different. Contact ignition is based on a mechanical interrupt system. However, this type of ignition is considered obsolete and is practically not used on modern motorcycles. Today, most modern scooters use a non-contact ignition system, which is based on the operation of a sensor, switch, primary and secondary ignition windings.

To set the ignition on the contact system, you first need to disassemble the crankcase. Then on the contact group you need to set the maximum allowable gap for a full circle of shaft rotation. Next, you need to set the piston to the distance from the dead center specified in the scooter's operating instructions. Then you should loosen the stator fastening and adjust it until the contact closes. Next, we assemble the crankcase in reverse order.

To set the optimal moment for a spark on a scooter with a contactless ignition system, you must first disassemble the crankcase. Then you need to make a mark on the crankcase and rotor at the position of the top dead center of the piston. In this case, the spark plug must be unscrewed. After which it is necessary, by turning the shaft, to record the moment the spark appears. Next, we make another mark on the crankcase. Thus, the distance between the two marks is a very important parameter, which is usually called ignition timing. The distance between the two marks gives us the so-called ignition advance. Now you need to loosen the bolts on the generator stator and set the ignition to the level specified in the scooter's operating instructions.

How to adjust the ignition on a scooter

Recently, our country has been gradually adopting the habits of China and similar Asian countries. In particular, one of these innovations was the purchase and riding of scooters. They are used not only by adults, who in this way are trying to reduce the cost of traveling to work or simply for traveling short distances (to the country, nature, fishing), but also by the younger generation. If adults understand at least a little about the specifics of how a scooter engine works and can, if necessary, adjust or repair it, then such a science is too complicated for young people.

Therefore, it will be important to acquire at least minimal setup skills and understand the main causes of possible breakdowns. One of the options for gaining knowledge about the principle of operation and the need for repairs or adjustment nuances would be to understand the basic techniques for setting the ignition

So, let's figure out how to set the ignition on a scooter, what it is and how important this knowledge is. A non-functioning ignition system or any of its circuits is the reason the entire scooter mechanism, or rather its main part, the engine, does not work. The ignition system itself is necessary so that the fuel ignites and moves the pistons, which move the wheels and, in fact, the vehicle.

Naturally, according to these conditions, the ignition system is one of the most important parts, the operation and configuration of which must be known in order to stay overnight on the road. The process of igniting the combustible mixture in the gas chamber begins with candles. They can become the main cause of the malfunction, which the unlucky driver will have to deal with when the need arises. To adjust the ignition and check the operation of the spark plug, it will not be enough to check for a spark, as in other types of transport. This is due to the fact that even with a spark on the spark plug, there may not be enough power to ignite the fuel.

However, it is necessary to check for the presence of a spark, for which it is unscrewed and secured to ground. It should be remembered that even this method requires safety measures, in particular, the candle cannot be held with your hands, but must be secured using a third-party conductive object (for example, wire). The presence of a spark will indicate the serviceability of the spark plug; if there is none, you can install a new spark plug and check the operation of it. The second step in setting up the ignition will be to check the operation of the second main part - the generator

In order to set the ignition correctly, it will be important to take into account its serviceability and high-quality operation. Checking the functionality of the generator is carried out by measuring the resistance

An indicator of the operating condition of the generator will be a resistance of at least 80 Ohms. If it is smaller or absent altogether, the generator is faulty and requires replacement. In addition, even an open circuit and measuring the resistance on the generator cannot be considered an accurate diagnosis of the malfunction. To make sure that the generator is the main cause, you will need to not only disconnect it from the ignition coil, but also remove it from the scooter. Only after this, having determined the resistance and identified reduced or absent resistance, it can be stated that the generator is the main cause of the breakdown and requires replacement.

In addition, it may turn out that the resistance on the removed generator will be normal, then the main cause of the breakdown, which is expressed in faulty wiring or a connection problem with the coil, will also be quite simply and quickly identified. Naturally, to set up and repair the ignition on a scooter, knowing the specific reason, it will take much less time and effort. So, after the generator has been checked and no fault has been identified, it is necessary to measure the circuit between the ignition coil and the switch with the generator block with a multimeter.

Having checked the integrity of the wiring, it will also be important to check for possible solders or short circuits between them. Quite often, poorly secured wires fall and heat up, which leads to a short circuit.

The last possible breakdown, the conclusion about which can be made after checking all the above components and assemblies, will be the ignition unit. Naturally, it will have to be replaced only if all other options and components of the faulty ignition system have already been checked and reliable data on their operation has been obtained.

Let's summarize the above

First, use a light bulb to check whether the switch generates a pulse or not:

If the light is on, the switch and the modules that ensure its operation are 100% operational
If the light does not light, it means that the switch or some module that ensures its operation has failed. And to understand for sure that the switch is faulty, we need to check all the modules.
If the modules turn out to be serviceable, but the switch does not generate a pulse, then it is faulty and you can safely replace it with a new one

In conclusion, I would like to warn you against the temptation to take a known-good switch from someone and plug it in instead of your own. Yes, with this express method the faulty switch will be identified immediately. If it was really faulty, then with a known good one, a spark will immediately appear.

But how can we be 100% sure that the scooter’s wiring is in perfect order and no one has managed to put their smart personality into it before you? What if something shorted there or some tusk messed up the wiring in its own way and then the working switch will be in complete trouble. And then you will buy two switches - one for the person you asked for, the second for yourself. Do you need it?

How to adjust valves on a 4-stroke scooter Information, operation, maintenance

So, maybe after replacing the CPG, your scooter has stopped selecting revs, or you just want to improve the performance of your scooter.

Adjusting the valves will help with this.

First you need to remove the cover from the cylinder head; to do this, unscrew the four bolts.

(photo 1.5)

Next, it is important to set the dead center, it is done like this. Remove the protection from the cooling fan and look at the marks on the plate

(photo 2,3)

After that we return to the valves. Let's look at how the camshaft sprocket is located, it is better to remember approximately how the marks are located

We begin to remove the bed with rocker arms

It is very important to unscrew the nuts evenly from the studs, crosswise. That is, a revolution of the upper left is a revolution of the lower right, a revolution of the upper right is a revolution of the lower right

When the nuts already begin to spin without tension, feel free to unscrew them, it may no longer be evenly distributed.

Unscrew the nuts and remove the bed, holding the camshaft.

Next, remove the timing chain from the camshaft sprocket and rotate the camshaft so that the marks on the sprocket coincide with the edges of the cylinder head, put on the timing chain.

(photo 4)

We check the marks again, if they are level, we return the bed with the rocker arms and tighten it. You need to tighten it in the same way as you untwisted it, evenly, otherwise the cylinder head and/or cylinder may become warped. Then you will have to completely disassemble the CPG, and most likely change the gaskets.

Afterwards we put everything back together in reverse order. We start it and check it.

Whatever it is: better, worse, or the same. Most likely you will want to try to do better.

Don't forget to set the dead center.

We disassemble again until the rocker arms are removed. Next, slightly raise the side of the camshaft on which there is no sprocket. So that the timing chain would be slightly loosened and it would be possible to lift it from the sprocket and rotate the sprocket. Scroll the sprocket one tooth forward or backward. As you wish. We twist it and check it.

If it’s worse, we set the dead center, unwind it and scroll it two teeth back. We twist it and check it.

Thus, by trial and error you will definitely set it the way you like it.

From personal experience I can say that once you set it correctly, you will never have problems with this matter.

scooter 4t

In order for the rotation of the generator rotor and gas distribution shaft to correspond to the desired piston operating cycle, it is necessary to set their position according to the marks. On the magneto body there is a marker for the position of the dead center of the cylinder in the form of the letter “T”. The rotor can be adjusted manually, or using a kick starter. The position of the camshaft is determined by the marks on the timing sprocket. Three points marked on the star from the outside form the top of which should be directed to the extreme position from the piston. Adjusting the ignition consists of setting the correct position of the timing star.

Ignition setup steps

The first possible breakdown is checked with a stroboscope; to do this, you need to check whether there are measured risks in the ignition synchronization. Rarely does anyone have an expensive strobe light for free use, but if you have the opportunity to ask your friends for it, then it’s better to start working with this check.

In order to start checking the synchronization of the marks on the system, you need to thoroughly warm up the moped motor. There is no need to strain the moped too much.

Connecting a strobe

After this, you should connect the strobe. If the technician is working with the device for the first time, he must first carefully study the operating instructions. Two wires come from the device, one of which should be connected to the moped’s power supply, and the second induction wire is connected to the spark plug.

A simple strobe for setting up the ignition of a moped

As soon as a spark appears on the spark plug during startup, the bright light of the strobe will indicate this. Now you should direct this light that appears to the location of the measuring marks and see how they are located relative to each other. If everything is correct, the risks are exactly the same, then the setup went as expected, no further adjustment is required.

Adjusting the ignition timing

If the measuring marks are not synchronously coupled with each other, or they are not visible, then you will have to adjust the start of the moped. More precisely, you will have to adjust the ignition timing. Different models of Chinese mopeds may have different adjustment methods. Therefore, before starting work, it is necessary to study the documentation attached to the moped. Adjustments must be made in accordance with the instructions.

If it is not clear where these measuring marks should be located, you should carefully inspect the generator flywheel, as well as the flywheel housing, and they will immediately show up.

Further work requires a careful approach and strict adherence to safety measures, since you will have to inspect and adjust the system with the engine running.

Equipment Features

Let's go back to the strobe

To operate, you need a type of this device that is equipped with a special sensor for counting the rotation of the hot shaft - this module is worth paying attention to

If a strobe light that does not have such equipment falls into the hands of a master, then it is necessary to slightly adjust the progress of the work. It is necessary to check the engine starting at idle speed. But there is also a nuance here - you should be sure that the idle speed works accurately.

The result of the test should be a position of the measuring marks in which the ignition will work perfectly. Once such a situation has been identified, it must be set. Further adjustments to other parameters are not recommended.

How is BSZ better than contact?

Having carefully read the previous section, you can see that the system uses an inductive non-contact Hall sensor. The advantage is obvious - there is no friction and commutation

For comparison, look at the contact system. In it, the breaker switches the voltage, the value of which is 12 Volts

Whatever one may say, the metal contacts are constantly in contact with each other, gradually wear out, and become covered with soot.

For these reasons, it is necessary to constantly monitor the breaker, adjust the gap, and carry out timely replacement. BSZ is devoid of these shortcomings, therefore, without third-party intervention, the system operates much longer. The Hall sensor fails very rarely, just like the switch

This increases the reliability of the system, but precautions must also be taken, in particular, the connection of the switch to the body must be as tight as possible to ensure effective heat exchange. In addition, BSZ allows you to improve engine performance, increase, albeit slightly, its power, along with increasing reliability
