ALTROZ SERVICE MANUAL

1.5L REVOTORQ ENGINE 67 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 recom- mended intervals. For air filter cleaning and air filter element replace- ment, please refer the “On vehicle service” section of this manual. B. INTAKE MANIFOLD The intake manifold is located between the air in- take 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 pre- ignition due to high intake air temperature. The in- tercooler is mounted in front of the radiator. D. AIR MASS FLOW SENSOR This sensor is mounted between air filter and turbocharger. It gives Information about the amount of air quantity & temperature entering the engine. This input is used by the ECU for corrections of fuel quantity based on amount of air availability for optimization of exhaust gas circulation & the turbocharger control. While assembling, the AMF sensor the point of the arrow should be towards the Turbo charger.
