The Engine Lubrication SystemVersión en línea The internal combustion engine contains numerous components that cause friction. Friction wears them out and causes them to overheat. To reduce friction and remove heat, cars use a lubrication system. In the video, we will look at the structure and operation of the vehicle engine lubrication system. por Robert Chircop 1 Why do engine use a lubrication system Written answer 2 For most vital parts of the engine (e.g. crankshaft), oil is delivered under Written answer 3 In an engine, oil is stored in the ...
