ENGINES AND PROCESS FOR USING THE SAME |
摘要 |
A rotary exhaust control valve for two-stroke cycle engines is disclosed. This valve is oriented at least partially within the exhaust passage and, for each revolution of the engine, delays flow from the combustion chamber through the exhaust passage during the expansion stroke of the piston while permitting full opening of the exhaust passage and blow down to initiate the scavenging cycle of the engine. The valve of the present invention permits complete opening and closing of the exhaust passage during the appropriate portions of the engine cycle. Also disclosed is a mechanical linkage mechanism between the rotary valve and the crankshaft to provide precise control of the exhaust valve throughout the engine cycle. |
