摘要:
An internal combustion engine (10) has at least one combustion chamber (15) defined by a piston (13) accommodated in a cylinder (11). The method of operating the engine (10) comprises opening an exhaust means (30) as the combustion chamber (15) expands to permit fluid to discharge from the combustion chamber (15), opening an inlet means (20) as the combustion chamber continues to expand to admit the intake air into the combustion chamber (15); closing the exhaust means (30) as the combustion chamber still continues to expand to interrupt discharge of fluid from the combustion chamber (15), and closing the inlet means (20) to interrupt admission of the intake air into the combustion chamber (15). With this operating sequence, scavenging of the combustion chamber (15) is incomplete and so there is a relatively large residual fluid within the combustion chamber.
摘要(中):
内燃机(10)具有由容纳在气缸(11)中的活塞(13)限定的至少一个燃烧室(15)。 操作发动机(10)的方法包括当燃烧室(15)膨胀时打开排气装置(30),以允许流体从燃烧室(15)排出,当燃烧室继续时打开入口装置(20) 膨胀以允许进入空气进入燃烧室(15); 当所述燃烧室仍然继续膨胀以中断来自所述燃烧室(15)的流体排放时,关闭所述排气装置(30),并且关闭所述入口装置(20)以阻止所述进气进入所述燃烧室(15) 。 通过该操作顺序,燃烧室(15)的清除是不完整的,因此在燃烧室内存在相对较大的剩余流体。
