研究了在有负荷时提高气缸功率的新的方法——靠把切断供油的气缸转换成充满新鲜空气的空压机工况工作,以获得工作气缸在增加循环供油量的同时增加空气充量。从被切断的气缸中吸取的补充空气沿作为空气储气管一部分的旁通管送入到工作气缸内,有利于发动机加速性能的提高。同时介绍了切断气缸的四冲程柴油机的结构。 A new method of increasing cylinder power at load is studied - by switching off the fueling cylinder to an air compressor filled with fresh air, the working conditions of the working cylinder are increased to increase the amount of air charge while increasing the circulating fuel supply the amount. The supplemental air drawn from the severed cylinder is fed into the working cylinder along a bypass tube that is part of the air reservoir, which is good for accelerating the engine. The structure of a four-stroke diesel engine with a cut-off cylinder is also introduced.
