发动机是汽车的心脏,发动机内有许多相互摩擦运动的金属表面,这些部件运动速度快、环境差,工作温度可达400°C至600°C。在这样恶劣的工况下面,只有合格的润滑油才可降低发动机零件的磨损,延长使用寿命,那么合格的润滑油要满足哪些要求呢?也就是说润滑油的六大作用是什么?
1、润滑减磨:活塞和汽缸之间,主轴和轴瓦之间均存在着快速的相对滑动,要防止零件过快的磨损,则需要在两个滑动表面间建立油膜。
有足够厚度的油膜将相对滑动的零件表面隔开,从而达到减少磨损的目的。
2、冷却降温:机油能够将热量带回机油箱再散发至空气中帮助水箱冷却发动机。
3、清洗清洁:好的机油能够将发动机零件上的碳化物、油泥、磨损金属颗粒通循环带回机油箱,通过润滑油的流动,冲洗了零件工作面上产生的脏物。
4、密封防漏:机油可以在活塞环与活塞之间形成一个密封圈,减少气体的泄漏和防止外界的污染物进入。
5、防锈防蚀:润滑油能吸咐在零件表面防止水、空气、酸性物质及有害气体与零件的接触。
6、减震缓冲:当发动机气缸口压力急剧上升,突然加剧活塞、活塞屑、连杆和曲轴轴承上的负荷很大,这个负荷经过轴承的传递润滑,使承受的冲击负荷起到缓冲的作用。
Engine oil Performs as a lubricant under tremendous heat and pressure and prevents friction between all metal surfaces in your engine when grinding together. It also transfers heat away from the combustion cycle and delays nasty by-products like silica (silicon oxide) and acids. There are three types of engine oils. First is mineral oil, which comes from the ground and are created from the oil refining process. Secondly is synthetic oil that is more expensive than mineral oil because of the chemical engineering involved in laboratories. It still has a base mineral oil, but it has been engineered to allow for more miles to be driven between oil changes. Lastly is semi-synthetic or premium oil, which is essentially a mixture of the above mentioned two.
