Filed: 1980-03-07
Abstract: PURPOSE: To sufficiently supply a narrow passage with a burning gas by providing a check valve at a down side of a throttle valve in a suction passage between the throttle valve and an opening of the narrow passage so as to prevent the burning gas from being released upstream in the suction passage.  
     CONSTITUTION: In the first cylinder 26, a burning gas is ignited and released outside by opening an exhaust valve 74. Just before the exhaust valve is closed, a suction valve 36 is opened, thereby allowing some of the burning gas to flow into a suction passage 18. After the burning gas enters the suction passage 18, a check valve 64 is closed. When a suction stroke appears in the third cylinder 30, a suction valve 42 is opened, thereby causing a difference between pressures in the suction passage 18 and a suction passage 22. Due to the difference, the burning gas from the first cylinder 26 flows into an outlet passage 52 of the third cylinder 30 and swirled inside the cylinder 30. While subsequent ignition appears successively inside the fourth cylinder 42, the second cylinder 28, the first cylinder 26, and so forth, the burning gas is carried through the narrow passage 46 into a subsequent cylinder and swirled therein without running away into an upstream area in the suction passage.
