Abstract
An engine intake system including a supercharger of a type wherein the intake air drawn from the intake air inlet port is compressed by the pressure of the exhaust gas before it is discharged through the intake air outlet port. A coarse air cleaner is provided in the intake pipe leading to the intake air inlet port and a fine air cleaner is provided in the intake passage communicating with the intake air outlet port, so that the pressure drop at the intake air inlet port can be minimized.
