This paper deals with highlighting the current information about Four Stroke Internal Combustion Engine. The current principle of Four Stroke cylinder engine includes axis of cylinder head. This in itself has channels that are used to supply the fuel. The new principle of the cylinder head for all 4 - stroke engines include the axis of the cylinder head,which in itself has channels that are used to supply burn - smiling or flue gases. Axle head gaskets into the cylinder head of engine that has the holes that much channel cylinder head and through which piston valves which leans slight ly wire spring on shaft of cylinder head. Such Four Stroke engine has enormous advantages over record circuits and permanent set no condition in engine. https://www.ijiert.org/paper-details?paper_id=140785
