Employment engine management system

The engine management system controls the ignition and fuel injection.

Fuel pump submerged in the fuel tank supplies fuel to the fuel line through the fuel filter. The system includes a pressure regulator which maintains the pressure of the fuel, it bypasses excess fuel back into the tank. In the fuel line established nozzles which inject fuel into the intake ports of the engine. In this engine uses a distributed fuel injection system in which injector fuel is injected independently. Unit controls the operation of nozzles, changing the length of time during which the injector is opened to provide feed richer or leaner fuel mixture.

The air passes through the air filter, the air flow meter and a throttle to the inlet pipe of the engine. The control unit analyzes the information from the air flow meter and the other sensor, and calculates the time of filing and the fuel injection amount in accordance with the measured air flow rate and speed. The longer the nozzle opening, the more fuel is injected.

Additional sensors transmit information to the control unit of the engine coolant temperature and air entering the engine, and in models with a catalytic converter - the contents of oxygen in the exhaust gases.

An activated carbon filter prevents the penetration of harmful vapors from the fuel tank into the atmosphere. Fuel vapors accumulated in the filter (absorber) and when the engine is fed into the engine cylinders together with air.

The memory unit in the control unit detects a fault that appears and writes its code. Failure of important sensor control unit switches to emergency mode. If the engine continues to run, although with less efficiency.

Ignition system creates in each cylinder of the engine at a certain moment the spark that ignites the compressed fuel-air mixture.
