2.1.4.2 COMPONENTS
A. INTAKE MANIFOLD
The intake manifold is fitted between the electronic
throttle valve through intake adaptor pipe and the
cylinder head. The compressed air from turbo-
charger via intercooler is metered through an
electronic throttle valve into the combustion cham-
bers of the four cylinders through intake manifold.
B. INTERCOOLER
The intercooler is a heat exchanger used to cool the
compressed hot air coming from the turbocharger
before it enters the intake manifold. It increases the
density of the air and avoids the chance of pre-
ignition due to high intake air temperature.
A Temperature and manifold air pressure sensor
(TMAP sensor)
is mounted on the outlet of the inter-
cooler to measure the boost pressure.
