What is the difference between an intercooler and a charge air cooler?

- Jun 26, 2019-

Pressurization is a technique in which air is pre-compressed and then supplied to the cylinder to increase the air density and increase the amount of intake air. It is relative to a naturally aspirated engine.


The supercharging is divided into waste turbocharging and supercharging, and the supercharged air can reach a temperature of more than 100 degrees. In order to reduce the temperature of the air entering the cylinder, an  charge air cooler is specially provided to cool the air, thereby further improving the combustion efficiency and reducing the exhaust gas of the engine.


The intercooling boost should be called intercooling. It is actually an air cooler that cools the pressurized high temperature air, which reduces the high temperature air to below 50 degrees. The aim is to improve the combustion effect and help to improve engine power. Adding a medium cold can increase the horsepower by about 30 percent. Generally, high horsepower engines will be equipped with intercoolers.
