    Abstract: A rotary exhaust control valve (38) for two-stroke cycle engines is disclosed. This valve (38) is oriented at least partially within the exhaust passage (30) and, for each revolution of the engine, delays flow from the combustion chamber (18) through the exhaust passage (30) during the expansion stroke of the piston while permitting full opening of the exhaust passage (30) and blow down to initiate the scavenging cycle of the engine. The valve (38) of the present invention permits complete opening and closing of the exhaust passage (30) during the appropriate portions to the engine cycle. Also disclosed is a mechanical linkage mechanism (72, 74) between the rotary valve (38) and the crankshaft to provide precise control of the exhaust valve throughout the engine cycle.

    Abstract: A sliding exhaust control valve (40) for two-stroke cycle engines is disclosed. This valve (40) actuates at least partially through the exhaust passage (30) and delays flow from the combustion chamber (18) through the exhaust passage (30) during the expansion stroke of the piston while permitting full opening of the exhaust passage (30) and giving complete blow down before the scavenging cycle of the engine. Also disclosed is a mechanical linkage mecanism between the slide valve (40) and the crankshaft (62) and cam controlled actuation means (52, 54, 56) to provide precise control of the exhaust valve (40) throughout the engine cycle.
