INTRODUCTION - FUEL TANK AND PIPES

1.4 16v TJet

CONSTRUCTION SPECIFICATIONS

The fuel supply system is the returnless type, i.e. with a single connecting pipe between the fuel tank and the engine.

The fuel tank is located in front of the rear axle. It is made out of plastic with high mechanical strength.

The fuel pressure is controlled by a dedicated differential pressure regulator fitted on the fuel manifold.

CONSTRUCTION SPECIFICATIONS

The fuel system is "returnless", i.e. with a single pipe connecting fuel tank and engine. The return pipe, filter and pressure regulator have therefore been eliminated. The filter and pressure regulator are built into the pump assembly.

This makes it possible to:

- minimize the possibility of the vehicle catching fire in case of an accident.

- reduce fuel vapour emissions into the atmosphere.

The fuel tank is located in front of the rear axle. It is made out of plastic with high mechanical strength.

COMPOSITION

The fuel system is divided into a low pressure circuit and a high pressure circuit.

The low pressure circuit consists of:

- an auxiliary pump submerged in the tank;

- the fuel filter;

- the fuel return manifold pipe;

- the connecting pipes.

The high pressure circuit consists of:

- the pressure pump;

- the single fuel manifold pipe;

- the injectors;

- the connecting pipes.
