Fuel,
Emission and Exhaust System
COMPONENTS AND DESCRIPTION
1.
Fuel Tank
A moulded plastic fuel tank is located in the
front wishbone of the frame. Access to the
tank components is gained by removing the
inspection panel inside the trunk.
2.
Fuel Pump
An electric rotary pump is used to provide fuel
for the system. The pump is mounted inside
the fuel tank.
3. Fuel Accumulator
The accumulator keeps the system under
pressure when the pump is not running. The
accumulator
is
mounted inside the rear
section of the frame backbone.
4.
Fuel Filter
A special filter is used to remove foreign
particles from the
fuel.
The filter is mounted
on the left rear frame
rail.
5. Fuel Distributor
The fuel distributor determines the necessary
volume of fuel to be delivered to each
injector.
6. Primary Pressure Regulator
The primary pressure regulator controls the
primary or main line fuel pressure in the
system.
The regulator is located inside the
fuel distributor.
7. Control Pressure Regulator
The control pressure regulator provides fuel
enrichment during warm up and cold
acceleration. The regulator is mounted on the
left valve cover.
8. Air Flow Sensor
The air flow sensor measures the amount of
air entering the engine.
9. Cold Start Valve
An electrically operated cold start valve is
used to supply extra fuel to the engine during
cold start conditions. The vaive is mounted
on the left side of the engine.
10.
Thermo-Time
Switch
The
thermo-time
switch regulates injection
time of the cold start valve. The switch is
mounted in the thermostat housing.
11.
Injectors
The injectors are always open when the
engine is running. Their main function is to
atomize the fuel as it enters the intake
chambers. The injectors are mounted in the
cylinder heads.
12.
Throttle Valves
The throttle valves control the amount of air
entering the engine. The throttle valves are
located between the mixture control unit and
the intake manifold.
