What is needed for proper installation?
To properly install gas equipment on a car, you will need a certain set of equipment and tools:
- HBO set 4;
- gas hoses with clamps 60-80cm long, Ø4-5mm and Ø12mm 50-100cm (for a 4-cylinder engine); 40-70cm vacuum tube Ø6mm; a cooling system hose with two metal tees corresponding to the size of the inlet/outlet on the gearbox - the length of all lines is selected individually for the car;
- thermoplastic gas tube of the required length (you can use copper or aluminum);
- auto tools;
- drill and/or screwdriver;
- drills (Ø4.8mm, crown 30mm);
- tap 6mm;
- electrical tape, heat shrink tube, hair dryer;
- soldering iron (materials for soldering wiring);
- multimeter;
- metal clamps/brackets with self-tapping screws (for fastening lines under the bottom);
- a can of anti-corrosion treatment or auto enamel;
- engine intake manifold gasket.
You will also need a lift/overpass or inspection hole.
Advantages and disadvantages of HBO Digitronic
Studying numerous reviews from owners of cars with 4th generation digitronic gas equipment, you can find both positive and negative sides.
Of the minuses, it is worth noting only complaints about the impossibility of self-adjustment, as well as premature failure of individual components of the system. But these disadvantages may be only partly true.
In practice, upon detailed analysis, it often turns out that the first and second statements are due to the incompetence of the technician who installed/configured the equipment. Also, untimely or low-quality maintenance of gas equipment or its absence at all.
However, do not forget about fake digital electronics. The advantages are obvious:
- a wide selection of trim levels for both budget small cars and premium cars.
- ease of self-installation, configuration, and maintenance. All instructions/manuals are available
- maintainability (spare parts/repair kits available)
- high quality of system parts and reliability of components (all components undergo multi-level testing)
- manufacturability, it is possible to diagnose and adjust equipment parameters directly from a smartphone through the original application.
How to connect all elements of the gas system?
Each 4th generation LPG kit must contain a connection diagram for an injection car; the system is installed according to it. For different manufacturers it may differ slightly (for example, the electrical circuit), but the general installation principle for all types of gas equipment is the same.
The installation process begins from the engine compartment. To begin with, it is advisable to protect the paintwork of the car by covering the lining and fenders with rag material. Remove the battery terminals.
Correct installation of gas injectors
In order to install HBO injectors, it is necessary to dismantle the intake manifold. You can, of course, not remove it, but then you are likely to encounter a number of difficulties:
- it is inconvenient to drill the manifold;
- violation of the correct/synchronous positioning of the nozzle nozzles (inserts);
- metal shavings getting into the engine cylinders.
If a plastic manifold is not so critical, then duralumin/aluminum, especially cast iron, is unacceptable to drill on the engine. This can lead to damage to the CPG (cylinder-piston group) or valves and their seats. The uniformity of gas supply depends on the correct location of the fittings.
So, after dismantling the manifold, as close as possible to the intake valves and the holes of the gasoline injectors, at the same angle (approximately 45˚), towards the center of the intake passage (along the air flow), we drill holes with a diameter of 4.8 mm. Also, to connect the vacuum, we make a hole in the manifold receiver, closer to the throttle valve.
Here it is important not to damage the walls of the wells of the standard injectors; also, mark and mark the drilling points in advance with a marker. Consider the possibility of reassembly so that the fittings do not interfere with the fastening of the manifold to the cylinder head.
Then, use an M6 tap to cut the thread and screw in each fitting using a hexagon or an appropriate wrench. Do not use excessive force; the brass inserts are easy to break off.
Some nozzles have tapered threads, so additional sealing is not worthwhile. But in some cases (for example, a hole has become loose) or for greater confidence, you can use a special sealing adhesive/thread locker.
We install the manifold in the reverse order, not forgetting to install a new gasket. Next, we screw the ramp with the injectors tightly to the engine, using a strip and dampers. We put on gas hoses/sleeves from the injectors to the fittings, securing them with clamps. There are four rules to consider here:
- the length of the hose should not be more than 15-20cm (the shorter the better);
- hoses must be cut to the same/equal length;
- do not exceed the nozzle angles recommended by the manufacturer;
- It is advisable to place the parts in an accessible place; hidden installation will complicate their maintenance.
Brief information about the brand
The products of the Polish company Digitronic are multi-brand gas equipment for any car. The key suppliers of components are such well-known companies as Stako, Valtek, Tomasetto, AC, AEB, EMER Palladio, Fagumit, whose production is located both in Europe and around the world.
Today, certified digital installation stations operate in sixteen regions of Russia. In addition, the company has a developed dealer network in all regions of the country.
The company is actively promoting its product, which has a positive effect on its promotion. Not counting retail customers, only the company’s wholesale customers are located in more than 200 cities of the Russian Federation and the CIS, whose number is about 1,300.
The main reasons why HBO Digitronic is in great demand among car enthusiasts and companies involved in the operation of vehicles:
- individual proposals for the selection of equipment;
- prompt technical support (online adjustment);
- personnel training (for equipment installation stations);
- providing a guarantee for work and equipment (with the possibility of extension);
- availability of a full range of spare parts in warehouses;
- fast delivery of spare parts;
- flexible pricing policy;
- high level of service.
In addition, due to the wide distribution of gas equipment of this brand throughout the world, the LPG market is flooded with counterfeits. “Chinese digitronic”, which has nothing to do with the original manufacturer, is especially common.
Differences between the original control unit and the fake
Therefore, the company has developed a number of measures to combat counterfeiting, one of which is to confirm the authenticity of products by registering them in its own system.
Digitronic gearboxes
For a gas cylinder system, the gearbox is one of the most important parts. Digitronic works with TOMASETTO gearboxes, which are designed for carburetor and injection engines and are part of the gas equipment starting from the second generation. Different models from this manufacturer differ in power and some variations in functions, such as preheating at the inlet or without an additional heating stage.
Products
The company supplies items such as:
- HBO cylinders are cylindrical and toroidal of various capacities;
- Nozzle (Injection) rails;
- Additional components and parts (multi-valves, filters, dispensers, mixers, clamps, tubes, rubber hoses and other consumables);
- Gearboxes;
- Various electronics (injection and traditional gas equipment, CVTs, emulators, sensors and indicators);
- Kits (for four, six and eight cylinders, as well as FSI with direct injection).
In addition, tuning systems, adapters, programming interfaces and much more are provided.
Equipment setup
Incorrect settings of the gas system negatively affect the function of gasoline injection. The car runs jerkily, runs unevenly, and does not start the first time. Car owners are guilty of low quality gasoline, gas fuel or spark plugs. As a result, it turns out that incorrect settings of the HBO ECU are to blame.
Digitronic 3d power setup instructions involve the following steps:
- you need to install the program on your laptop;
- connect the cable from the laptop to the ECU;
- turn on the ignition;
- run the manual and click OK when prompted to “update the program”;
- Next, work begins with Digitronic 3d power curves.
To figure out what values should be on the settings display, you need instructions for setting up digitronic 3d power. You should approach the matter with knowledge of the principle of operation of the gas system.
Operating principle of 2nd generation gas equipment on an injector
2nd generation HBO is extremely common and popular in our country. Both because of the low price, affordable to almost every ordinary car owner, and because of the ease of operation, setup and adjustment. In any case, LPG is installed with the desire to save on gasoline, the prices of which are increasingly higher. The number of gas filling stations is increasing, and the level of service in installation and repair of gas equipment is getting better.
Before talking about the features of 2nd generation LPG on carburetors, we note important recommendations that must be followed if you want your car to work properly with such a combination - an injector and 2nd generation LPG:
- there should always be gasoline in the fuel tank;
- warm up in the cold season only on gasoline.
Digitronic control unit MAXI 2
For four cylinder engines, Digitronic has developed the MAXI 2 control unit. This line is designed to reduce installation and calibration time.
The basis of the unit is a thirty-two-bit processor with the possibility of upgrading. Such a unit can be quickly installed thanks to a small number of wires and a sealed compact housing. Calibration is carried out through functions located on two panels, which eliminates the problem of switching between tabs. There is a separate button with a buzzer, which is connected using three wires.
The software capabilities of the unit include displaying engine operating parameters on an oscilloscope, a gasoline injection time map in 2D format, functions for correcting gas pressure and temperature with corresponding maps, heating gas injectors, setting the maximum load on the gas mixture, changing the time for opening and closing injectors, as well as the flow through them, and much more.
The MAXI 2 unit is compatible with almost forty manufacturers of gas injectors, including AEB, Hana, Valtek, Rail, Matrix. Functional and software characteristics have made Digitronic MAXI 2 one of the most popular on the Russian market.
