About Automotive Engineering; Engine Lubrication Systems

Basic Functions of lubrication system-Six main functions of Lubrication subsystems Basic components of lubrication system-Basic components of the lubrication systems Types of lubrication in IC engines-Pressure lubrication , Splash lubrication Properties of Lube oils-Flash point, pour point, viscosity, Viscosity index, Oil pressure signal in Engines Lube oil terminology-grades of lubrication , How to judge the grades of lube oil and climatic conditions in which the oil must be used Calibrate lube oil dipstick-When replacing a missing or defective dipstick, replace the engine oil and filters, installing the exact OEM specified quantity. Run the engine for a couple of minutes then shut down and leave for 10 minutes. Dip the oil sump with the new dipstick and scribe the high level graduation with an electric pencil. Measure the distance from the high-level to low-level graduations on the old dipstick and then duplicate on the replacement.
