What is the purpose of an intercooler in an engine?

[Opal]

An intercooler in an engine can reduce the intake air temperature. Lowering the intake air temperature can enhance power output and reduce the likelihood of engine knocking. However, only turbocharged engines are equipped with intercoolers, while naturally aspirated engines do not have them. The intake principles of turbocharged engines differ from those of naturally aspirated engines. Relevant information about intercoolers is as follows: 1. Introduction: An intercooler is essentially a component paired with turbocharging, and it is typically found only in vehicles equipped with a turbocharger. 2. Function: Its role is to lower the temperature of the compressed air, thereby reducing the engine's thermal load, increasing the intake air volume, and consequently boosting the engine's power.
