Many cars and trucks are written on their sides as turbo intercooler or simply intercooler. what does it mean? Actually an intercooler is an additional component fixed to a turbo charger to improve its performance and efficiency. It is similar to a radiator whereas a radiator cools the engine but a turbo intercooler cools the air which is fed into the engine. Lets see it brief here.
A turbocharged engine has a turbocharger which sucks and compresses the air from outside into the engine with the help of burnt exhaust gases coming out of the engine. Initially the air entering into the engine is cold so it has more oxygen, good density and volume. The dense and oxygen rich air aids in better combustion and does the work of turbocharger very efficiently. But as the time moves on, the air which is compressed by the turbocharger into the engine gets heated up due to compression. Usually when air is compressed its temperature rises and becomes hot. This hot air has low density, volume and minimum oxygen content, therefore it affects the performance of the engine.
The solution to this problem is the turbo intercooler. The turbo intercooler cools the compressed air from turbocharger and feeds it to the air intake system of the engine. So the air entering into the engine is made dense and cold. Hence it has high oxygen content and volume, which is necessary for better combustion of fuel.
The intercooler is placed before the radiator or underneath the radiator to draw the cold air directly as the vehicle moves on. Almost all turbocharged cars are intercooled. In india, cars which are equipped with intercoolers are swift, ritz, indica tdi as well as indigo tdi, vista qudrajet, scorpio, xylo, octavia, verna, safari, punto, i10, i20, older accent, MB, 320d, Toyota Fortuner, Ford endeavor etc..
