THE GENERAL DATA

Arrangement of elements of system of injection of fuel in a motor compartment


1 – the fuel filter
2 – a throttle
3 – a regulator of pressure of fuel
4 – fuel atomizers
5 – a casing of the air filter

The scheme of connections of elements of fuel system and system of catching of steams of fuel

1 – the electromagnetic valve of clearing
2 – a regulator of pressure of fuel
3 – a throttle
4 – an inlet collector
5 – the fuel filter
6 – the fuel pump
7 – the pumping over pump
8 – the valve
9 – the return valve
10 – двухходовый the valve
11 – the canister
12 – the control valve

All models are equipped by electronic system of injection (EFI). On the majority of models the electronic system of injection MPFI, and on models with engines of 1,8 l – SPFI is established. The fuel system consists of a fuel tank, the electric fuel pump shipped in a tank, the relay of the fuel pump and atomizers. On models 4WD the separator of steams of fuel is established. In a fuel tank of models 2WD the fuel pump and the gauge of level of fuel are executed in the form of one block. On models 4WD the divided fuel tank with two gauges of level of the fuel, located in each section of a fuel tank is used. The fuel tank on models 4WD is equipped by the pumping over pump which pumps over fuel from the left section in right that the fuel weight was distributed in regular intervals.


The prevention

The fuel system is under pressure long time after engine deenergizing. At any separation топливопроводов it is necessary to remove preliminary pressure in fuel system.
