The temperature increases, so that not only affects the charging efficiency, but also easy to produce deflagration. Therefore, the device to reduce the intake air temperature is the intercooler. It is installed between the outlet of the turbocharger and the intake pipe to cool the air entering the cylinder. An intercooler is like a radiator.
It is cooled by wind or water, and heat from the air escapes into the atmosphere by cooling. According to the test, the intercooler with good performance can not only keep the compression ratio of the engine to a certain value, but also reduce the temperature to increase the intake pressure and further improve the effective power of the engine.
