Functions of Engine Lubrication System: 1. Lubricate Engine parts to minimize wear. 2. Lubricate Engine parts to minimize power loss due to friction. 3. Act as a seal between piston and cylinder wall. 4. Absorbs shock between bearings and other engine parts. Thus extending engine life reducing noise and breakage of engine parts. 5. Act as a cooling agent. 6. Also act as a cleaning agent. Properties of oil: a. Viscosity. b. Power point. c. Resistance to carbon formation. d. Oil oxidization resistance. e. Compression and rust protection. f. ...
