A four-stroke engine is an internal combustion engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: Intake, Compression, Power, and Exhaust. It is used widely in various automobiles (that especially use gasoline as fuel) like:- trucks, cars, and some motorbikes.
NOTE: Inorder to design fourstroke engine, varieties of components must be kept together.Though this is not the exact design as the exact one requires many more parts; but this very design only consists of four components such as: piston head, Crankshaft, connecting rod and the outer body which is setup in such a manner that the engine is created
