    Abstract: In a two-cycle internal combustion engine having a main combustion chamber and a pressurized crank case joined by a main scavenging passage and a main intake passage to the crank case from a main carburetor, the addition of an auxiliary combustion chamber connected to the crank case by an auxiliary scavenging passage through a pressure receiving chamber. An auxiliary intake passage is connected to the auxiliary scavenging passage between the crank case and the auxiliary chamber, and a check valve is situated in the auxiliary scavenging passage intermediate the intake passage and the auxiliary combustion chamber. An auxiliary carburetor supplies a relatively rich mixture to the auxiliary combustion chamber while the main carburetor supplies a lean mixture to the main combustion chamber whereby ignition of the mixture in the auxiliary chamber produces a blast of flame into the main chamber through a passage called a torch nozzle to ignite the mixture in the main chamber thereby achieving a more complete and consistent combustion in the main chamber.

    Abstract translation: 在具有主燃烧室和加压曲轴箱的双循环内燃机中，由主清扫通道和主进气通道从主化油器连接到曲轴箱，添加连接到曲轴箱的辅助燃烧室 通过通过压力接收室的辅助扫气通道。 辅助进气通道连接到曲柄箱和辅助室之间的辅助扫气通道，并且在进气通道和辅助燃烧室之间的辅助扫气通道中设有止回阀。 辅助化油器向辅助燃烧室供应相对较浓的混合物，而主化油器将主要的燃料混合物供应到主燃烧室，由此辅助室中的混合物的点燃通过称为火炬的通道产生火焰喷入主室 喷嘴以点燃主室中的混合物，从而在主室中实现更完整和一致的燃烧。
