ABSTRACT:
A multi-cylinder internal combustion engine having a plurality of cylinders which do not fire one after another and intake ports for the cylinders. A mechanical supercharger is disposed in an intake passage. An intake resonance passage having no enlarged volume space or chambers, which consists of a resonance passage part and a collecting passage part directly communicating with the resonance passage part, is connected to an outlet port of an intercooler forming a pressure reflecting portion. The intake ports for the cylinders are separately communicated with the collecting passage part by way of a plurality of independent intake passages. A bypass passage is connected between the collecting passage part and the intake passage downstream the mechanical supercharger so as to form a circular passage running the mechanical supercharger, intercooler, intake resonance passage.
