The function of an oil control orifice is that it regulates the pressure of engine oil supplied by the oil pump for the lubrication of cylinder head mechanism and other purposes.

The size of engine cylinder is referred in terms of its bore and stroke.
The stroke of an engine is the distance between T.D.C and B.D.C.
There are two types of piston rings
1. Compression Rings
2. Oil Control Rings
The top portion of the piston is called as a piston crown.
In an engine, the temperature of the piston will be more at the crown of the piston. The piston crown is subject to the high temperatures in the combustion space and the surface is liable to be eroded/burnt away. For this reason, the material from which the crown is made must be able to maintain its strength and resist corrosion at high temperatures.
