Engine (03.00)
Evaporative Emissions (03.13)
Description
The evaporative loss system prevents escape of fuel vapours
into the atmosphere.
Fuel vapour is displaced from the fuel tank during filling.
Vapour is also displaced due to fuel evaporation in higher
temperatures. Displaced fuel vapour is absorbed in the
carbon canister filter located on top of the fuel tank.
During normal engine running, absorbed fuel vapour is
purged from the carbon canisters and mixed with the normal
fuel/air charge in the inlet manifold.
System Operation
Displaced fuel vapour leaves the fuel tank via the normally
open fill level vent valve and the roll over valves. It passes
through the carbon canister where fuel hydrocarbons are
absorbed. Clean air leaves the system via the normally open
canister vent valve. This valve is only closed during
diagnostic pressure testing of the fuel system.
During normal engine ru nning, the single vapour
management valve in the engine bay is periodically opened
allowing fresh air flow into th e open canister vent valve,
through the carbon canister, through the vapour
management valve and into the primary inlet manifold. This
fresh air flow progressively purg es any absorbed fuel vapour
from the carbon canister.

Description
This vehicle uses a return less fuel system in which the fuel pump, controlled by the fuel pump driver module, is run to
supply fuel through one in-tank filter to the fuel rail (Refer to ’Fuel Charging System (03.04)’, page 3-5-1). A pressure senso r
and a temperature sensor are fitted on th e primary fuel rail. The fuel pump speeds are varied as required to regulate the
fuel pressure in the fuel rails.

Fuel Tank
The fuel tank incorporates a single filler neck and check valve, internal fuel pump, internal fuel filter, a sender unit and an
‘on board refuelling vapour recovery’ system.
Fuel Pumps
) X H O 3 X P S
The modular fuel pump is immersed in the base of the fuel
tank. The pump can deliver up to 150 litres/hour. The in-
tank fuel line connects to the external line using a quick-fit
connector in the base of the fuel tank. During normal running, pressu
rised fuel from each fuel
pump passes from the tank, through an 3 micron in-tank fuel
filter to one of the two fuel rails on the engine.
Fuel temperature is measured on the primary fuel rail. If fuel
temperature becomes excessive, the fuel pressure is
increased to prevent fuel vaporisation (boiling).
Fuel pressure is measured by sensors on each fuel rail. The
fuel pressure to each rail is regulated as required by
continuously changing the run speed of the associated fuel
pump. Maximum pressure in the system is limited to 5.3 bar
by in-tank pressure regulators.
A constant head of fuel is maintained in the fuel pump
modules to ensure that the pumps cannot run dry in a ‘low
fuel’ situation.

Evaporative Loss System
Fuel vapour is displaced from the fuel tank during filling.
Vapour is also displaced due to fuel evaporation in higher
temperatures. Displaced fuel vapour is absorbed in the
carbon canister filter located on top of the fuel tank.
During normal engine running , absorbed fuel vapour is
purged from the carbon canister and mixed with the normal
fuel/air charge in the inlet manifold.
System Operation
Displaced fuel vapour leaves th e fuel tank via the normally
open fuel level vent valve and the roll over valves. It passes
through the carbon canister where fuel hydrocarbons are
absorbed. Clean air leaves the system via the normally open
canister vent valve. This valve is only closed during
diagnostic pressure testing of the fuel system.
During normal engine running, the single vapour
management valve in the engine bay is periodically opened,
when negative pressure exists in the intake manifold,
allowing fresh air flow into the open canister vent valve,
through the carbon canister, through the vapour
management valve and into the primary inlet manifold. This
fresh air flow progressively purges any absorbed fuel vapour
from the carbon canister.
Fuel Tank Vents and Control Valves
On-Board Refuelling Vapour Recovery
All of the vapour displaced from the tank by refuelling passes
through a series of valves and through a carbon canister. This
filters out and stores all the fuel vapour and clean air exits the
carbon canister port.

Normal Fuel Fill - Air displaced from the fuel tank during
filling can only exit via the fuel level vent valve and roll over
valves and be forced through the carbon canister. Any fuel
vapour in the displaced air is absorbed in the carbon filter
material. No fuel vapour can escape to the atmosphere.
Clean air then exits the carbon canister, via and additional
filter, to atmosphere.
Excessive Fuel Fill - In the event of overfilling of the fuel
tank, the fuel level vent valve will close at normal maximum
fuel level. Finally the roll over vent valve will close,
completely sealing the tank. Any excess pressure in the fuel
tank will ‘blow off’ via the Ov er-pressure vent valve (part of
the roll over vent valves) in the Fuel Level vent valve
assembly.
Safety Precautions
Operations on fuel system resu lt in fuel liquid and vapour
being present in the working environment. This presents a
very serious risk and the following precautions must be
strictly observed:
Specifications
Warning
Operations on refuelling and the fuel system must only
