ENGINE 102 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.
