四次燃烧原理

四次燃烧原理
The four-stroke combustion principle is a fundamental concept in the operation of internal combustion engines. This principle involves a series of four distinct phases that occur during the combustion process. The first phase is the intake stroke, during which the intake valve opens and the piston descends, allowing a mixture of fuel and air to enter the combustion chamber. 这是四冲程燃烧原理的第一阶段，这个阶段主要是进气过程，进气阀打开，活塞下降，使燃料和空气混合物进入燃烧室。

The second phase is the compression stroke, where the intake and exhaust valves are closed, and the piston ascends, compressing the fuel-air mixture. This compression increases the temperature and pressure within the combustion chamber, preparing the mixture for ignition. 这是四冲程燃烧原理的第二阶段，这个阶段主要是压缩过程，进气和排气阀关闭，活塞上升，压缩燃料和空气混合物。

这个压缩增加了燃烧室内的温度和压力，为点火做准备。

The third phase is the power stroke, where the spark plug ignites the compressed fuel-air mixture, causing it to rapidly expand and force
the piston back down. This downward motion of the piston generates the engine's power output. 这是四冲程燃烧原理的第三阶段，这个阶段主要是动力过程，火花塞点燃了压缩的燃料和空气混合物，导致它迅速膨胀，迫使活塞再次下降。

这种活塞的下降运动产生了发动机的动力输出。

The fourth and final phase is the exhaust stroke, where the exhaust valve opens, and the piston ascends, expelling the combustion by-products from the combustion chamber. This completes one cycle of the four-stroke combustion process, and the cycle repeats to continue powering the engine. 这是四冲程燃烧原理的第四阶段，这个阶段主要是排气过程，排气阀打开，活塞上升，将燃烧副产物从燃烧室中排出。

这完成了四冲程燃烧过程的一个循环，并且该循环重复以继续为发动机提供动力。
