Abstract

A cross charge transfer (CCT) engine according to an embodiment of the present invention includes a 90 degree, four-cylinder engine that operates with two banks of paired cylinders. Air only is drawn into the pumping annulus through a valve. As the piston ascends, a fuel charge is transferred through a crossover system to the opposite smaller diameter or working cylinder. The engine then operates as a loop scavenged engine, except that the crankcase isolation afforded by the CCT engine enables significant fundamental durability and operational advantages.
