PURPOSE:To increase output by forming a chamber for the communication of each combustion chamber of the contiguous cylinders between these contiguous cylinders and installing a valve for opening each of subintake port and a subexhaust port into the chamber. CONSTITUTION:When suction valves 6,... in combustion chambers 17 and 17 are operated by a camshaft for suction valve, and main intake ports 4c,... are opened, and pistons 1 and 1 are lowered, mixed gas is sucked into the chambers 17 and 17 from carburetors 5 and 5 through the ports 4c,... and at this time, a suction valve 9 is operated in a chamber 18, and a subintake port 4f is opened. Therefore, mixed gas is sucked into the chambers 17 and 17 from also a carburetor 8 through the port 4f and the chamber 18, and the suction efficiency is improved. After the mixed gas in the chambers 17, 17 and 18 is combusted, the exhaust valve 7,... are operated by a camshaft for exhaust valve, and the combustion gas is discharged through the main exhaust ports 4d,... and at this time, also an exhaust valve 10 is opened, and the exhaust is discharged also from a subexhaust port 4g. |
