The objective of a turbocharger is to improve an engine's volumetric efficiency by increasing the density of the intake gas (usually air, entering the intake manifold of the engine). When the pressure of the engine's intake air is increased, its temperature will also increase. Turbocharger units make use of an intercooler to cool down the inlet air. In the existing direct charge air coolers the atmospheric air is used to cooling down the charge air. It means the charge air is fed to the direct charge air cooler located at vehicle front, and then it flows returned to the engine through the long routing.Here, our purpose is to bring the temperature of intake air nearer to the ambient temperature & reducing the pressure drop. The intercooling of intake air is greatly increased by installing a specially designed intercooler i.e. Indirect charge air cooler in which air will run as hot fluid and coolant (glycol + water) will run as cold fluid. The intake air will be cooled down by the air flowing through the fins of the intercooler and the coolant coming from the Low temperature radiator which is mounted on in front of High temperature Radiator at the vehicle front. And hence the density of air is increased by increasing the temperature drop across the intercooler.
