Fuel system
1 - fuel pressure regulator;
2 - nozzle;
3 - the fuel filter (the high pressure circuit);
4 - the back seat;
5 - connector of the fuel pump;
6 - a cover; | 7 - the fuel hose;
8 - Hose fuel vapor removal system;
9 - pulsation damper;
10 - an arm of the fuel tank;
11 - the fuel tank;
12 - the fuel pump. |
Fuel system consists of the following elements:
- Electric fuel pump;
- The fuel filter (2);
- Fuel;
- The fuel pressure regulator;
- The injectors (4);
- The fuel pump relay.
The electric fuel pump delivers the filtered fuel pressure on the fuel line to each nozzle. To minimize noise during operation of the fuel pump is installed in the fuel tank.
The fuel pressure is regulated by a special valve controller. The voltage at the nozzle is supplied from the battery via the main switch.
The fuel is metered and injected through the injection nozzles opening in accordance with signals received from the control unit (PCM), wherein the needle is retracted from the seat and fuel is injected into the cylinder through the opening of the injector nozzle.
The amount of fuel fed into the intake tract of the engine is determined by the duration of pulses generated by the engine control unit and supplied to the injectors.
Fuel pipes and hoses allow the transfer of fuel from the fuel tank to the fuel lines and injectors and return excess fuel to the tank. Fuel lines attached to the bottom of the car, must be periodically inspected for dents and deformation as due to narrowing of the passages may be restricted fuel flow.
Fuel pipes and hoses also ensure the transfer of fuel vapors from the fuel tank to the canister with the activated coal, where they are going with the engine off. After engine start-up and warm up to operating temperature the engine control unit opens the solenoid valve and the fuel vapor from the canister into the engine and burned.
