1.2L REVOTRON ENGINE 85 5. 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 intercooler is mounted in front of the radiator. 6. Turbocharger (Waste Gate Turbocharger) Turbochargers are a type of forced induction system. They compress the air flowing into the Engine .The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the charging. This can significantly improve the power-to-weight ratio for the engine. In order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) -- that's about 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the temperatures in the turbine are also very high. 7. Manifold Air Pressure Sensor And Temperature Sensor (T-MAP) T-MAP sensor consists of a silicon chip mounted inside a reference chamber. On one side of the chip is the reference chamber and on the other side is the pressure to be measured. The electrical resistance of the chip varies with the variation of pressure. This change in resistance alters the voltage signal. ECM interprets the voltage signal as pressure and any change in voltage signal as change in pressure. The temperature sensor element is a NTC resistor.
