Temperatures inthe cylinder are naturally high , though only the cylinder combustion space andpiston crown are subjected to actual flame temperatures . The piston ringsexert a varying pressure on the liner walls under conditions involving rapidlychanging speed and reversal of direction of motion . Oil is supplied to thecylinder liner wall and the piston rings by means of mechanical lubricatorsgiving a carelly controlled oil feed , through injectors or quills . And insome designs it is timed so that the oil impinges only on the piston ring belt, thus ensuring the most sfficient lubrication.
The films of oilbetween the rings and the liner and between the rings and the grooves in thepiston are not only essential for lubrication by products of combustion . Someof these are acidic , particularly if residual fuels are being used and cancause corrosive conditions wich promote heavy rates of wear . Also , lacquerand carbonaceous deposits form in the ring belt which interfere with thecorrect operation of the rings . To counteract these undesirable effectscylinder oils usually contain additives formulated to impart a high degree ofalkalinity . The alkalinity neutralizes the acid conditions and the detergency cleanses the rings and grooves .

汽缸中的温度自然是很高的,然而只有汽缸燃烧空间和活塞顶接触到真实的火焰温度.活塞环在具有速度不断变换和反向运动的情况下对套壁施加大小不一的压力.在精心控制下通过喷油器或注油枪送入机械润滑油来为汽缸套壁和活塞环供油.在某些设计中,给油是定时的,这样油只会喷到活塞环带上,以确保最充分的润滑效果.

环和衬套以及环和活塞槽之间的油膜并不仅仅是必不可少的燃烧副产物的润滑剂.这些副产物中有些是酸性的,特别是当残余燃料被应用时会导致腐蚀环境产生,这会急剧加速磨损率.而且漆质和碳质的沉淀会在环带上形成,这会妨碍活塞环的正常运转.为了抵消这种不良的后果,汽缸油通常含有高碱性配比的添加剂.其碱性中和了酸性环境,其去污成分清洁了环和槽.
