Abstract: The two-stroke engine has a plurality of intake passages extending from the external air inlet port through the crankcase, separating the intake air charge from the air and oil vapor within the crankcase. The piston has one or more corresponding inlet tubes depending therefrom that telescope within the crankcase intake passages as the piston reciprocates. All intake air travels through these passages and is separated from the remainder of the crankcase volume. The incoming air charge passes through a concentric poppet valve in the piston crown to enter the combustion chamber. Fuel is provided by conventional direct or port injection and ignition is provided by one or more conventional spark plugs. Diesel operation is achievable when the engine is configured appropriately. Exhaust exits the combustion chamber through a poppet valve in the cylinder head, the poppet valve being actuated by a rocker arm and pushrod from a crankshaft driven cam.

Abstract translation: 二冲程发动机具有从外部空气入口通过曲轴箱延伸的多个进气通道，将进气空气与曲轴箱内的空气和油蒸汽分离。 活塞具有一个或多个相应的入口管，当它们随着活塞往复运动时，它们在曲轴箱进气通道内望远镜。 所有进气通过这些通道并与曲轴箱体积的其余部分分离。 进气通过活塞冠中的同心提升阀进入燃烧室。 燃料由常规的直接或端口喷射提供，并且点火由一个或多个常规火花塞提供。 当发动机配置适当时，可以实现柴油机操作。 排气通过气缸盖中的提升阀离开燃烧室，提升阀由摇臂和曲轴驱动凸轮推动驱动。
