1.	What are the main objectives of lubrication system?
Answer» The main role of the engine oil is to move the any system such as the piston in cylinder and the crankshaft smoothly. In order to achieve the objective: • The oil forms an oil film at the metal surface to reduce the friction between the metal surfaces. • The engine oil doesn’t allow the combusted gas to leak to the crankcase. • It cools the pistons and valves. It gives washing action to the cylinder wall by moving away the micro particles (impurities) to the sump. • It reduces the shock, transmitted from the piston to the crankshaft.
