摘要:
An intake system is incorporated in a multi-cylinder internal combustion engine having a plurality of cylinders each being provided with at least three intake ports, at least one of the three intake port being timed to close after the remaining intake ports which are timed to close closely to each other. The intake system includes a main intake pipe introducing intake air into the intake system. The main intake pipe is connected to the remaining intake ports of the cylinder by way of a common intake pipe and to the at least one intake port of the cylinder by way of an intake pipe provided independently from the common intake pipe.
