Fuel System

Fuel System:

Introduction
Fuel is stored in the fuel tank mounted across the vehicle behind the passenger compartment bulkhead.
Fuel is drawn by the fuel pump from the tank and then supplied to the two fuel rails via a filter.
Fuel injectors, controlled by the ECM are installed in the fuel rails on each side of the intake manifold.
The amount of fuel injected into the engine is controlled by the ECM.
A cross-over pipe connects the two fuel rails together at the front of the manifold.
A test valve in the cross-over pipe allows the fuel rail to be pressurized and de-pressurized during the servicing and troubleshooting procedures.
A pressure regulator on the rear of the right fuel rail controls the pressure in the fuel rails. A return line directs excess fuel from the pressure regulator back to the fuel tank.

Fuel Injectors







Eight, side-fed, dual straight-jet fuel injectors are installed in the fuel rails.
The injectors are electro-magnetic solenoid valves ECM-controlled.
The fuel spray from the injectors are directed onto the back of the intake valves.
The amount of fuel injected into the engine is controlled by the ECM.


Pressure Regulator







The pressure regulator is a diaphragm-operated valve that regulates fuel-rail pressure at 2,9 bar above the intake manifold pressure.
The regulator is located at the rear of the right pressure rail.
