INTAKE MANIFOLD
1. Fuel rail
2. Injector
3. Throttle body
4. Ignition coil
5. Manifold air pressure sensor (MAPS)
6. Intake manifold
Theintakemanifoldismountedonthetopofthe
engine on both cylinder heads. It provides support
for the fuel injectors, the fuel rails, MAPS (man-
ifold air pressure sensor) and the throttle body.
The air intake manifold is a resonator between
the throttle body and the air intake at the cylinder
heads.
Fuel Rail
Two fuel rails, one for each injector, are mounted
on the intake manifold. The fuel rails ensure all
the time, that enough fuel at the right pressure
can be delivered to the fuel injectors. The fuel rails
are fed by the fuel pump with a fuel pressure of
approximately 400 kPa (58 PSI).
Fuel Injector
Two fuel injectors (one per cylinder) are used to
inject fuel into the intake port of the cylinder head.
Throttle Body
It is a 52 mm heated throttle body mounted on
intake manifold. Fitted on the throttle body, there
is the TPS and the idle bypass valve which allows
the ECM to control the RPM while the throttle
plate is closed.
FUEL PUMP MODULE
A32I18A
The fuel pump module is located inside the fuel
tank. The module includes fuel pump, fuel pres-
sure regulator and fuel level sensor.
Fuel Pump
It provides fuel pressure and flow rate to the sys-
tem.
Fuel Pressure Regulator
A fuel pressure regulator controls the pressure in
the system and allows excess fuel to return to
the fuel tank. The fuel pressure regulator regu-
lates the fuel pressure at approximately 400 kPa
(58 PSI).
Fuel Pickups
Two fuel pickups come with 70 micron filter. One
is located at the front right side of the fuel tank
and the other at the rear left side.
