- Precisely dose the amount of injected fuel in any operating mode of the engine, which ensures low fuel consumption with optimal driving performance.
- Reduce the content of harmful substances in the exhaust gases due to accurate measurement of the amount of fuel and the use of a variable catalytic converter.
- Perform self-diagnosis for quick troubleshooting. The system is equipped with a fault memory. If malfunctions occur during operation, they are recorded in the memory. If the engine is not running optimally, the workshop can print out a list of faults so that they can repair the damage themselves if necessary.
The engine control unit is a small, fast computer. It sets the optimum ignition timing, fuel injection timing and fuel injection amount. In this case, the operation of the control unit is coordinated with other vehicle systems, for example, gearbox control or anti-theft.
Elements of the ignition and injection system for a long time retain their performance and require virtually no maintenance. As part of the maintenance, it is only necessary to replace the air filter element, as well as replace the spark plugs. More serious tuning and repair work can only be done with the help of special devices.
Safety Precautions When Working on a Gasoline Engine Injection System
- Do not use open flames, do not smoke, do not keep any hot or very hot parts near the work area. There is a danger of an accident! Keep a fire extinguisher ready.
- Keep the workplace well ventilated. Fuel vapors are poisonous.
- The fuel system is under pressure! Before dismantling hose connections, relieve fuel pressure, refer to Section Depressurizing the fuel system.
- When dismantling hose connections, for safety reasons, the connection must be covered with a thick cloth.
Warning: When working with injection system components, you must also follow the general safety and cleanliness rules described in Section General information and security measures.
Elements of the engine control system for a long time retain their performance and require virtually no maintenance. As part of maintenance, only the air filter element and fuel filter need to be replaced.
