4-TEC Supercharged Intercooled Engine
Air for combustion is drawn at the back of the en-
gine by a mechanical driven supercharger. The
compressed air flows through one 52 mm throt-
tle body and is controlled by a throttle plate and
an idle bypass valve. The air continues through
the intake manifold, which contains the water/air
intercooler (which cools down the intake air) and
goes into the cylinder head.

FUEL DELIVERY SYSTEM
BASIC OPERATION
When the intake valve reaches the correct posi-
tion, the ECM (Engine Control Module) opens the
fuel injector and fuel is discharged into the intake
port at the air intake manifold by the high fuel pres-
sure inside the fuel rail. The air/fuel mixture enters
then the combustion chamber through the open
intake valve. This mixture is then ignited by the
spark plug.
