Filed: 1989-11-28
Abstract: PURPOSE:To accelerate the exhaust of combustioned gas and suppress the blowing-through of the uncombusted amount of fuel by installing a chamber in the course of an exhaust passage, which chamber communicates with the passage through a rotary valve. CONSTITUTION:In a two-stroke engine 1, an exhaust outlet port 5 opened in a cylinder 2 is opened and closed by the forward motion of a piston 8. On the way of an exhaust pipe 9, there is installed a chamber 15 communicating with the pipe 9 through a rotary valve 16. The rotary valve 16 makes the chamber 15 communicate with the exhaust pipe 9 two times at the time of early opening and late opening of an exhaust port 5. This accelerates the exhaust of combustioned gas, in the scavenging process from the early opening of the exhaust port 5 to the opening of a scavenge port 4. At the time of the late opening of the scavenge port, the exhaust pipe 9 increases the inner pressure to suppress the blowing-through of the fuel.
