- A) accurate dosing of the amount of fuel in each engine operation mode, which ensures lower gasoline consumption while maintaining good dynamic performance;
- b) reduction of harmful exhaust gases as a result of precise fuel dosing and exhaust gas cleaning (OG) using a catalyst controlled by an oxygen sensor;
- V) self-diagnosis of the electronic unit, which allows you to quickly find the fault. The electronic engine control unit has the function of self-testing and recording failures and malfunctions during vehicle operation. If during operation failures occur in the ignition or injection system, they are recorded. In the event of malfunctions in the engine rot injection system as a whole, in a specialized workshop, you can get a sheet with a printout of fault codes for a fee in order to independently eliminate one or another defect if necessary.
The ECM is a small, fast computer. It determines the optimal ignition timing, fuel injection and the amount of fuel injected. In this case, the engine control unit coordinates its actions with the control units of other vehicle systems, for example, with the gearbox control unit or with the anti-theft system.
All parts of the ignition and fuel injection systems are designed for a long service life and practically do not require repair. As part of the maintenance, it is only necessary to change the removable filter element of the air filter, as well as the spark plugs. Basic adjustment and repair work can only be carried out using expensive instrumentation.
For this reason, repairs and adjustments should be entrusted to specialized workshops with the necessary instruments and devices.
Safety Rules for Working on the Fuel Injection System
- No open flames or sparks near the workplace!
- No smoking!
- The workplace must be equipped with a fire extinguisher!
- Ensure good ventilation of the work area. Fuel fumes are poisonous.
- The fuel system is under pressure. Depressurize the fuel system before disconnecting the hoses.
- Before disconnecting the pipelines, put a rag on the connection.
