气缸减压装置是对具有高压缩比的柴油机降低其气缸压力的装置。它通过操纵减压手柄,转动减压凸轮轴,上顶(或下压)气门摇臂,使气门开启,气缸内部与大气相通,减低压力,便于发动机起动。这一装置同时又是一种熄火装置,发动机可在无振动状态下停止转动。气缸减压装置可分为进气门开启式和排气门开启式两种。为什么要装设此减压装置呢?因为具有较高压缩比的柴油发动机,在压缩冲程时,进、
The cylinder pressure reducing device is a device that reduces the cylinder pressure of a diesel engine having a high compression ratio. By manipulating the decompression handle, the decompression camshaft is turned on and the valve rocker arm is pushed up (or pushed down) to open the valve and the interior of the cylinder is communicated with the atmosphere to reduce the pressure and facilitate the starting of the engine. At the same time this device is a flameout device, the engine can stop rotating without vibration. Cylinder decompression device can be divided into two types of intake valve opening and exhaust valve opening. Why install this decompression device? Because of the higher compression ratio of the diesel engine, the compression stroke, into,
