Four Stroke Engine Essay
The earliest internal combustion engine used in a system that rose to fame was the four stroke cycle, where an internal combustion engine is a heat engine in which the burning of fuel occurs within the confined space of an engine’s combustion chamber. Expanding hot gases act directly onto pistons, rotors and sometimes the whole engine to cause movement. The internal combustion engine(14) The four-stroke engine was one of the earliest improvements made to internal combustion engines in the late 1800s. The four-stroke engine was invented by Jean Joseph Etienne Lenoir, which provided a reliable and continuous source of power. It was first patented by Eugenio Barasanti and Felice Matteucci in 1854, followed by a first prototype in 1860. In 1862

Just to give an idea of the level of significance of such invention to the world, especially in the motorcycle world, all three Grand Prix Classes have been won by those with two-stroke engines for ‘as long as people can remember’. Nearly all Formula One drivers learnt their craft driving two-stroke Karts and most board powered boats and personal water craft are still cruised or races under two-stroke power. (ref 13) The two-stroke engine was then improved by Joseph Day, an English engineer who designed the Valve-less Two-Stroke Engine in 1889. Originally there were two flap valves in Joseph Day’s design: one in the inlet port where usually a reed valve is found in a modern two stroke engine, and one in the crown of the piston. They were then removed when the engine was modified after coming up with the idea of transfer ports a few years later with the aid of one of Joseph Day’s workmen, Frederick Cock, who made the modification which allowed the skirt of the piston to control the inlet port and do away with valves, giving rise to the classic piston ported two stroke. The two stroke engine is much lighter than its four stroke counterpart. It does not compose of any valves and therefore requires much less lubrication than the four-stroke engine does. It can also be constructed in a
