1发动机润滑系统型式(1)压力润滑。压力润滑就是在汽缸体或汽缸盖上设置专门的润滑油道,利用机油泵使润滑油具有一定的压力,通过润滑油道向零件的润滑面间输送润滑油。润滑油在进入主油道前,要先经过滤器过滤(有的发动机设润滑油粗、细过滤器)。主油道上有4条油路,第1条通到正时齿轮,第2条通到曲轴轴颈和连杆轴颈,第3条通到凸轮轴轴颈再通过汽缸体油道到达摇臂轴,第4条通到空气压缩机。多数发动机对速度较高、机械负荷较大的零件都采用压力润滑型式润滑。为显
1 engine lubrication system type (1) pressure lubrication. Pressure lubrication is in the cylinder block or cylinder head to set up a special lubrication Road, the use of oil pump lubricant to a certain degree of pressure, through the lubricating oil Road lubrication parts to the interface between the transmission of lubricants. Before entering the main oil lube oil, it must be filtered through the filter (some engine oil lube, fine filter). There are 4 oil passages on the main oil passage, the first one goes to the timing gear, the second one goes to the crankshaft journal and the connecting rod journal, the third one goes to the camshaft journal and then reaches the rocker arm through the cylinder block oil passage Shaft, Article 4 leads to air compressor. Most engines on the higher speed, mechanical load larger parts are used pressure lubrication type lubrication. For the obvious
