Fuel consumption VAZ 2114 injector 8 valves

Continuing the line of the “nine”, beloved by domestic car enthusiasts, the “Samara 2” or VAZ 2114 model was released. A new dashboard was installed in the car, the exterior was modernized, and the interior was improved. The car was released in 2001 and immediately received positive feedback from its owners. It turned out to be so popular that production continued until 2013. Among the advantages of the car are:

1. Attractive appearance.
2. Reliable, economical and dynamic engines.
3. Economical average fuel consumption on all modifications of the VAZ 2114.
4. Maintainability.
5. Optimized chassis.
6. Reasonable price for any of the configurations.

How to preserve a VAZ-2111 in winter

In order for the VAZ-2111 to serve for a long time, it is necessary not only to promptly eliminate faults related to the operation of the electrical circuit, but also to properly maintain the car. Experts give the following recommendations:

1. Washing is good, but after cleaning the car it won’t be superfluous to treat the body parts with liquid wax. Why is this necessary? Wax fills even the smallest pores that appear in the paint, and dirt does not penetrate there, which means you can save money on another wash.
2. If you are not satisfied with the roughness that a rag leaves after wiping off dirt, use polishing and rub the liquid glass. The latter will keep the VAZ-2111 in the best condition for at least 1.5 years.
3. Many owners of domestic cars want to turn a boring vehicle into a real modern car. To do this, owners stick stickers on the surface, but no one takes into account that they are a real dust collector for small debris and dirt.
4. Drive your car with care - service station workers assure that any scratch can be retouched by painting the part, but they do not specify that it is almost impossible to select an identical shade of paint previously used by the manufacturer. Therefore, the entire car has to be repainted.
5. The headlights of the VAZ-2111 are made of plastic - this is how the designers take care of the recycling of raw materials. But plastic wears out over time and becomes cloudy. To extend the life of your headlights, initially protect the surface with armored film.
6. There is an opinion that seat covers prevent abrasion of the seats themselves, but this is not the case. Moreover, it is easy to wash the seats; special products are used for this.

Replace your wipers promptly; they will protect the glass from scratches.

This free collection contains all the necessary documentation for the electrical equipment of the VAZ-2111 car - the circuit itself, the heating system, headlight cleaner, electronic engine control module and fuse box. The VAZ 2111 is the first station wagon in the line of front-wheel drive cars, which is a modernized concept of the rear-wheel drive VAZ 2104. In it, the wiring diagram for the injector and a number of other components have undergone changes as part of the concept change. Diagrams for other models can be viewed here.

How to understand the need for an oil change

Removing the gas tank is carried out using a standard set of tools: wrenches of different sizes, a screwdriver and a hammer in case any element is difficult to dismantle. Signs of its malfunction, in addition to increased fuel consumption, may be a decrease in power, the engine stalls at idle, and the percentage of harmful impurities in the exhaust gases is exceeded.

• gasoline consumption increases if the filter responsible for the air supply becomes clogged;
• another reason is unstable tire pressure;
• if the filter is clogged;
• Gasoline consumption on the injection VAZ 2114 increases if there is a breakdown, for example, of the oxygen supply sensor or DSA;
• poor quality fuel;
• The reasons for the increase in consumption may be a non-standard radius or a low level of compression.

Many motorists, especially beginners who have just purchased a VAZ-2114, have wondered how the 8-valve injection engine that is installed on this car works. This article will discuss the design of the motor, its main characteristics, as well as dismantling and repair features. This information will be very useful for beginners and those who do not know how the main power unit works.

What sensors affect the fuel consumption of the VAZ 2115?

Malfunctions of the air flow sensor (or absolute pressure sensor), lambda probe, and phase sensor (camshaft position) have a noticeable effect on gasoline consumption. But the “dying” of the crankshaft sensor more often leads to the fact that the engine completely stops starting.

In the last few years, fuel consumption of about 6 liters per 100 km has been considered optimal in terms of economy. Fuel consumption of the Lada 2115 Samara ranges from 7.3 to 7.8 liters per 100 km. Lada 2115 Samara is available with the following types of fuel: Gasoline AI-92, Gasoline AI-95.

Basic malfunctions of the ignition switch and their elimination

The most common reasons why a car owner has to replace the ignition switch include:

• loss of a key (and lack of a spare one);
• mechanical damage (including a piece of key getting stuck in the lock);
• burning of the lock contact group.

If the first two problems can be established without additional diagnostics, then you can find out whether the entire ignition switch is externally working only by carrying out a small check. You will need any multifunction tester (multimeter) for this.

Checking the ignition switch

It is performed as follows:

1. Set the device to ohmmeter mode.
2. Remove the column casing.
3. Disconnect the block with wires from the lock.
4. Find pins 7 and 4 on the lock connector.
5. Connect the probes to them, and then turn the key in the lock (setting it to the “Ignition” mode).
6. Find pins 7 and 3 and connect the probes to them.
7. Turn the key, setting it to the “Engine Start” mode.

If the ignition switch is fully operational, then in both cases the ohmmeter will show no resistance (otherwise it can be concluded that the lock is faulty).

To understand this issue in more detail, it is necessary to consider all the reasons and nuances that affect the decrease or increase in fuel consumption.

Fuel tank design

The main function of a fuel tank is to store a certain amount of fuel. At the same time, everything must be organized so that the likelihood of a fire hazard is minimized.

On VAZ cars the fuel tank is located under the rear seats. Due to this placement, in the event of serious accidents and car overturns, the tank in most cases remains undamaged. VAZ fuel tanks are made of leaded steel sheets. Thanks to a thin layer of lead that protects against corrosion, the service life of the tank is significantly increased. The outside of the fuel tank is covered with dark enamel.

The fuel tank, covered with dark enamel, is reliably protected from corrosion

The fuel storage volume of the VAZ 2108 and other similar models is 43 liters. This takes into account the reserve, but it is not recommended to fill the tank to the brim. You should always leave a free volume of about four liters. It is especially important to do this in the summer, since the fuel expands as the temperature rises. If the tank is filled to the brim, then after swelling it may simply burst. The volume of the VAZ gas tank is designed in such a way that the autonomous mileage is enough for 500 kilometers, and this is considered a normal road segment in modern conditions.

The tank is securely fixed to the car body using flexible and durable plate-type clamps. Rubber gaskets must be placed under the clamps to ensure a tighter connection.

The tank mounting plates are very flexible and durable

Gasoline is poured through the neck on the right (in the direction of travel) rear side of the body. It is closed with a screw cap.

Main elements of the fuel tank

The neck is connected to the tank cavity through the filler hose. The other two tubes are integrated with a seven-liter separator installed outside the tank and designed to capture gasoline vapors. As a result of wear, the separator may split along the seam and gasoline will begin to leak out. It can be replaced without dismantling the tank. Moreover, you can temporarily cover the separator seam with a gasoline-resistant sealant.

Oil is supplied to the main and connecting rod bearings, as well as to the camshaft supports under pressure; the cylinders, pistons, pins and rings, camshaft cams and pushers are lubricated by splashing; all other associated parts are lubricated by gravity. Removing the gas tank is carried out using a standard set of tools: wrenches of different sizes, a screwdriver and a hammer in case any element is difficult to dismantle.

VAZ 2113 (2114, 2115) - model description

VAZ 2113 – Produced from 2005 to the present. It differs from the previous model with modified body panels and interior.

History of the creation of the VAZ 2113

The car and its modifications appeared in the Volzhsky Automobile Plant model range as a restyled version of the obsolete VAZ-2108 family. By 2005, the level of comfort that cars of the VAZ 2108 family could provide, against the backdrop of an ever-increasing flow of foreign-made cars, ceased to be competitive. In view of this, it was decided to switch to the production of a restyled family of cars while maintaining the same body. This family was supposed to occupy the lowest price niche in the VAZ model line after the final discontinuation of the “classic” models.”

Technical features of the VAZ 2113

The “Thirteenth Model” and its modifications are produced in the same body, but with modified hinged panels, such as the trunk lid, fenders, hood and others.

The interior, compared to the first front-wheel drive family, has changed quite a lot - panels, ceilings, door cards, dashboard and instruments themselves - all of this has been modernized for installation in the new model.

The VAZ 2113 engine was initially installed the same as on the 2108 - an eight-valve transverse engine with a distributed injection system. In 2007, engine capacity increased to 1.6 liters. When equipped with a new engine, the car complies with Euro-3 standards.

In 2010, a limited number of models of the family began to be equipped with a sixteen-valve VAZ-21124 engine with a power of 90 hp from the VAZ 2110 and a forced VAZ-21126 (98 hp) from the LADA Priora. With these engines, the car's rated maximum speed is 185 kilometers per hour.

Modifications of VAZ 2113

Just like in the previous 2108 family, the car is available in three modifications. In addition to the three-door hatchback, the VAZ 2114 model, which replaced the VAZ 21093, is on the assembly line of the Volzhsky Automobile Plant. It differs from the previous model 2114 in the design of the front part of the body with new block headlights, PTF, a modified hood, fenders, radiator grille, other plastic bumpers, moldings and a spoiler , painted in body color.

VAZ 2114

There are also significant differences in the interior design. For example, the VAZ 2114 has a height-adjustable steering column, which was not present in the 2109.

It is noteworthy that 2114 appeared earlier than 2113 - the first car of this model rolled off the Togliatti assembly line in October 2001. Since 2007 (due to stricter standards for the amount of harmful substances in the exhaust), the car has been equipped with a modernized 1.6-liter VAZ-11183 engine that meets Euro-3 requirements. The model receives the VAZ-21144 index.

VAZ 2114

The updated engine is equipped with a new phased injection system to improve efficiency.

Not only the power plant was subject to changes, but also the interior: the car was equipped with a more modern and less noisy dashboard (popularly nicknamed “Europanel”), with an on-board computer, VDO instruments with two liquid crystal displays. The computer shows not only the trip parameters and fuel consumption, but also the outside air temperature, voltage in the on-board network, time, and so on.

VAZ-2115

A four-door modification that replaced the VAZ 21099. The VAZ-2115 became the first modification in the line of restyled cars of the family. Pilot production of the modified “99th” began back in 1997. The VAZ 2115 is equipped with a new trunk lid, front and rear optics, body-color bumpers, a trunk spoiler, side skirts and a number of innovations in the interior and electrical equipment.

VAZ-2115

The suspension, transmission and braking system are borrowed from models of the 2108 family, although their modernization was initially planned. The angular shapes in the exterior are a thing of the past. By lowering the rear edge of the trunk, loading things has become noticeably more convenient.

Particular attention was paid to improving electrical equipment. The equipment included: power windows for the front doors, PTF, and new headlights. In the luxury version, the car is even equipped with heated front seats. A trip computer that allows you to monitor the condition of the lamps, oil level, brake pad wear, and the level of coolant and washer fluids is included in any package.

VAZ-2115

From 1997 to 2000, the 2114 was equipped with VAZ-21083 carburetor engines with a displacement of 1.5 liters and a power of 71.6 liters. With. Since 2000, with the start of mass production, this power unit was replaced by a VAZ-2111 engine with distributed fuel injection. The volume remained the same, but the power increased to 77.8 liters. With. Since 2008, they stopped installing the VAZ-2111 engine, replacing it with the more advanced VAZ-11183, with a volume of 1.6 liters and a power of 80.9 hp. With.

Production of the VAZ-21099 continued until 2004, and then the old model was discontinued, completely replacing the “fifteenth”.

In 2008, the VAZ-2115 underwent minor changes, affecting mainly the exterior.

General features of the internal combustion engine design • The car never let me down, although I found myself in different situations.

Operating procedure

Often when repairing an engine, it becomes necessary to disconnect high-voltage wires. Some drivers, after disconnecting the wires, do not remember the order in which they were installed. As a result, there may be confusion with the wires, and if they are connected incorrectly, the car will not start. To avoid an unpleasant situation, you need to know how the internal combustion engine operates.

Connecting wires to a VAZ 2109

The principle of operation of the power unit is based on such a property of gases as the ability to expand when heated. A standard four-cylinder engine operates in 4 strokes:

1. During the first stroke, the air-fuel mixture and part of the exhaust gases are “injected”. This mixture completely occupies the volume of the cylinder.
2. In the second cycle, the “compression” process occurs. In this case, the valves are closed, and the piston moves upward due to the movement of the crankshaft and connecting rod. The working mixture fills the combustion chamber.
3. On the third stroke, called “expansion,” a spark appears thanks to the spark plugs, which ignites the working mixture. The expanding gases exert pressure on the piston and force it to move downward. Then, thanks to the connecting rod, the crankshaft begins to move.
4. On the fourth stroke, the process of “release” of exhaust gases is carried out. Through the exhaust valves they enter the exhaust system of the VAZ 2109.

In order for the operation of a multi-cylinder engine to be smooth and the crankshaft not to experience uneven loads, it is necessary that the work processes be carried out in a certain order.

There are different schemes that determine in what sequence the cylinders will function. The VAZ 2109 uses the following scheme: 1-3-4-2. The cylinders are numbered starting from the front cover of the power unit.

Cylinder numbering on the VAZ 2109

If we imagine the working process of the engine through the cylinders, then the order of operation is as follows:

1. In the first cylinder, an upward movement occurs, the working process takes place: the air-fuel mixture burns, the gases expand.
2. In the third, a “compression” process is carried out, in which the piston moves upward.
3. The fourth receives the working mixture as the piston moves downwards, thus carrying out the “injection” process.
4. In the second, the piston moves upward, while the exhaust gases exit through the exhaust valves.

The main culprits of overspending

Monitor the main parameters of the gas distribution system, valve timing, valve fit to the head seats, wear of the cams, camshaft bearings and timing gears, condition of the cylinder head gasket and head, clearances between the bushings and valve stems, depth of valve recessing in the cylinder head seats. It received a power of 90 horsepower, which accelerated the car to 185 kilometers per hour, while the time to reach the first hundred was reduced and required only 11.

Electrical wiring system maintenance

To ensure the functionality of the electrical system, it is necessary to regularly check and diagnose the components:

1. If problems are detected in operation (even minimal malfunctions), the condition of the connecting plugs should be analyzed.
2. Often, after the owner moves the pad, contact is restored. Further use of such elements is not recommended.
3. The unit needs to be replaced with a similar one, while simultaneously finding out the cause of oxidation of the old parts.

Relay contacts are prone to burning when exposed to high current. The devices can be removed from the unit and the condition of the conductive contacts can be inspected.

This requires:

1. Remove the plastic protective cover.
2. Carefully clean the burnt contacts with fine sandpaper and blow with air.

If there is significant wear on parts, it is necessary to install new relays.

Due to the location of the installation box in the air supply channel, it becomes clogged with dust and is exposed to moisture. Over time, this leads to the destruction of the conductive paths on the printed circuit boards and loss of contact. The unit should be inspected once a year; if defects are found, it is recommended to replace it with a new one. At the same time, it is necessary to monitor the condition of the grounding wire, which can oxidize at the connection points.

For correct operation of consumers, it is necessary to check the condition of voltage sources. The battery should be periodically recharged from a stationary device. Charging the battery and the functioning of the electrical circuit while driving depends on the tension and condition of the generator rotor drive belt. When the commutator and brushes wear out, the operation of the generator is disrupted, which leads to the car losing power.

What oil to pour and when to change © Engine capacity 15

It is necessary to strictly monitor the fuel injectors, fuel pump and fuel filter, which primarily suffer during long-term operation and lead to high fuel consumption. The problem may also be a malfunction of the electronic control unit, which is responsible for the fuel injection program, since the VAZ 2114 engine type is an injector.

How does the controller monitor the operation of the injector?

When determining the specific position and opening time of the injector design, the specific volume of fuel entering the valves of the VAZ-2110 cylinder is determined. At the same time, thanks to special sensors installed on the motor, the on-board computer records specific values ​​and transmits them to the controller.

Subsequently, the controller, based on the information coming from the on-board computer, makes a decision on the position and duration of opening of the injector damper. If the controller malfunctions, the injectors will not be adjusted correctly, and the engine may stall while driving.

Tip: when starting the engine, the injector controller operates in asynchronous mode until the engine reaches a certain number of revolutions. That is why, after replacing the silent blocks of the front control arms on a VAZ-2110, you should warm up the car for 10-15 minutes.

Engine repair

Repair of the VAZ 2115 engine is carried out typically for the entire series of Samara and Samara 2 engines. Thus, replacing the VAZ 2115 thermostat is carried out within half an hour. To carry out the procedure, you will need to drain the coolant and unscrew the housing. Then replace the thermostat itself directly.

Also, the water pump and gas distribution mechanism repair kit are very easy to change. Every car enthusiast can change engine oil without problems, and a beginner can find instructions on the Internet.

As for major repairs, everything is much more complicated here, since this procedure is recommended to be carried out in a car service center. Not every car enthusiast knows how to repair or bore a cylinder block. Other operations, such as cleaning injectors, are also recommended to be carried out in a car service center.

For those who want to preserve the engine longer and extend its service life, it is recommended to reduce the period of scheduled maintenance to 10,000 km.

In addition to the scheduled oil change, other diagnostic work should be carried out on the VAZ 2115 engine at each service center. For example, it is necessary to visually inspect the engine for leaks, check the condition of the timing belt and diagnose the performance of all systems and sensors. It is worth remembering that good maintenance extends the life of the engine.

FAQ

After looking through the forums and talking with auto mechanics, we can come to the conclusion that owners of the VAZ 2115 engine with 8-valve injector ask the same questions every time. Let's try to take into account the data obtained, and then group the questions and give answers to them.

• Do valves bend in a VAZ 2115? — As with any other vehicle, of course it’s oppressive. This happens when the timing belt breaks. To prevent this from happening, it must be changed every 45-50 thousand kilometers or if failure is suspected. It is worth noting that it will not only bend the valves, but also damage related elements, and may also leave a mark on the pistons. In any case, this will lead to a major overhaul of the power unit.
• Where is the engine number on the VAZ 2115? — As in all Lada models, you can find the engine number on the gearbox side, near the thermostat. The engine number always has a pad on the cylinder block, which is located in a visible place.
• What is the oil volume in the 2115 engine? — The engine oil volume is 3.5 liters. But, with this question, car enthusiasts ask another one - What oil is best to fill in the 2115 engine? — The most recommended motor oil for the engine is considered to be 10W-40. Also, auto mechanics recommend using 5W-30 and 5W-40. In this case, the oil manufacturer remains at the discretion of the vehicle owner.
