1.5L REVOTORQ ENGINE 73 COMPONENTS A. AIR FILTER The Air filter is of dry type. The purpose of the air filter is to clean the atmospheric air from dirt & dust before entering the engine cylinder. Air filter needs to be cleaned periodically and replaced at recommended intervals. For air filter cleaning and air filter element replacement, please refer the “On vehicle service” section of this manual. B. INTAKE MANIFOLD The intake manifold is located between the air intake pipe supplying air from the intercooler and cylinder head. It is mounted on the cylinder head. The air from the air filter flows to the engine cylinder through the air intake manifold. C. 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 preignition due to high intake air temperature. The intercooler is mounted in front of the radiator. D. T-MAP SENSOR T-Map sensor is mounted at the air intake elbow. It measures temperature and pressure of fresh air. On the basis of which EMS ECU estimates the air flow and compares with actual air flow measured from Air mass flow sensor (AMF).
