The power supply system of the engine consists of the fuel tank, the electric fuel pump, the regulator of pressure of fuel, the block of the EFI relay, the relay of the fuel pump, the distributive fuel highway, nozzles, the air filter and throttle knot and fuel-supply lines. All models are equipped with consecutive electronic system of injection of fuel (Sequential Electronic Fuel Injection system).
The consecutive electronic system of injection of fuel counts quantity and gives fuel to engine cylinders as their work. Nozzles are run by the control unit of the engine (PCM). On the basis of information from various sensors, the PCM block the block operates fuel nozzles, changing the impulse length, i.e. an interval of time when nozzles are open. The amount of fuel constantly changes to provide an optimum ratio for start of the hot or cold engine, warming up, the mode of idling and acceleration. The throttle knot serves only to operate amount of the air given to engine cylinders.
Fuel from the fuel tank to fuel system moves on the metal tubes fixed under the car bottom. The electric fuel pump,
the fuel level sensor
and the regulator of pressure are located in the fuel tank.
The relay of the fuel pump is operated on two electric chains. On the first chain control is exercised from the control unit of the engine (PCM), and on the second — from the ignition lock. If after inclusion of ignition start of the engine is not carried out, the PCM block will switch-off the relay of the fuel pump through 2 pages. At the following start of the engine, after the first impulse from the sensor of position of the camshaft, the relay turns on the fuel pump.
The system of production of the fulfilled gases consists of a final collector, a reception exhaust pipe, the central and back mufflers and catalytic converter. Catalytic converter carries out purification of the fulfilled gases.
