Description

  The present invention relates to an intercooler that cools intake air.

In an engine equipped with a supercharger, an intercooler that cools intake air that has been compressed by the supercharger and has reached a high temperature is provided in the intake passage.
The intercooler that cools the intake air with the traveling wind must be placed at a location where the traveling wind passes.
