Abstract

PURPOSE:To enhance the charging efficiency of air fuel mixture gas in an internal combustion engine at low speed time by providing a rotary changeover valve and a sub air intake passage at the air intake passage at the downstream side of the throttle valve and introducing the mixture gas from the sub air intake passage into a combustion chamber to thereby take place turbulence flow state. CONSTITUTION:There are arranged a throttle valve 12 and a rotary valve 14 at an air intake passage 5, and a sub air intake passage 17 for communicating with the upstream and downstream of the valve 14 when the valve 14 closes the passage 5. A vacuum disphragm unit 21 driven by means of air intake tube vacuum to be introuced through a vacuum passage 27 is connected to the valve 14, which is directed to closing operation at low speed time of the engine. Accordingly, the mixture gas is introduced from the passage 17 into the chamber 4 to thereby take place turbulence flow of the mixture gas in the chamber 4 so as to thereby enhance the charging efficiency of the mixture gas in the engine.
