Piston

An engine is usually comprised of what called as piston. The piston is used to transmit the power to the shafts and this power is obtained by the internal combustion of the petrol or diesel. The piston is usually cylindrical in shape and is closed at one end on its other end it is connected with the connecting rods for it’s to and fro motion. The piston is usually made as alloys of steel or aluminum. The piston is generally surrounded by piston rings in order to make it air tight. There should be a proper lubrication between the piston and its ring because the to and fro motion of the piston generates friction as a result of which the life of the piston rings might go down. Hence lubrication has to be provided to increase the life of the piston. The piston rod in turn connects with the crank shaft which is responsible for the rotation of the wheels. Thus the piston comprises of a piston rings and piston pins. The piston pin connects the piston and the rod. The piston which is responsible for transferring energy has to be lubricated and well maintained. The efficiency of the engine depends on the ability of the piston to transfer the energy.
