PRIN. OF INTERNAL COMBUSTION ENGINES - OD1619 LESSON 2/TASK 2
increase in energy adds to the amount of heat generated, causing moving parts that
are deprived of oil to melt, fuse, and seize after a very short period of engine
operation. The effectiveness of a modern lubrication system makes possible the use
cylinder walls is severe, making effective lubrication of this area imperative.
Lubrication of the connecting rod and main bearings is crucial because of the heavy
loads that are placed on them. There are many other less critical engine parts
that also need a constant supply of oil, such as the camshaft, valve stems, rocker
arms, and timing chains.
