内燃机的润滑方式基本上有三种:飞溅润滑;压力循环润滑;复合润滑(压力循环润滑和飞溅润滑的复合)。压力循环润滑就是通过机油泵,将油底壳中的机油输送到各个运动摩擦表面。机油的供给需保持一定的压力,才能建立起油膜,起到润滑作用。内燃机正常工作时的机油压力一般在1.0～5.0kgf/cm~2范围内,这个压力数值是在油压表上显示出来的。机油
There are basically three types of internal combustion engine lubrication: splash lubrication; pressure cycle lubrication; compound lubrication (pressure cycle lubrication and splash lubrication compound). Pressure cycle lubrication is through the oil pump, the oil pan oil delivered to the various sports friction surface. Oil supply needs to maintain a certain pressure, in order to establish a film, play a lubricating effect. Engine oil pressure during normal work is generally 1.0 ~ 5.0kgf / cm ~ 2 range, the pressure value is displayed on the hydraulic gauge. Oil
