ENGINE 63 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 turbocharger via intercooler is metered through an electronic throttle valve into the combustion chambers 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 intercooler to measure the boost pressure. For more information on TMAP sensor refer EMS section in this group.
