Types of automobile Engines
Two Stroke Engine: As is indicated by its name, a two-stroke engine functions on two strokes as opposed to the more popular four-stroke engines. Very rudimentary in its design, the two-stroke engines are often used in mopeds, snowmobiles, lawnmowers and a few motorcycles. They are noisier, less fuel efficient and cause greater pollution in comparison to four-stroke engines. Interestingly, the largest compression-ignition engines are two-stroke and it finds its applications in various large vessels and locomotives.
Four Stroke Engine: Invented by Nicolaus Otto, the four-stroke engine finds its use in cars, light aircrafts and large boats. Compared with the two-stroke engines, the four-stroke engines are less noisy, more efficient and larger in size.
Bourke Engine: A refined version of the two-stroke engine, the strokes in a Bourke Engine occur without the mixing of burnt gas and fresh incoming air and due to less friction between piston and cylinder walls, the fuel efficiency is also more. Also, the expansion ratio of a Bourke Engine is greater, which translates to optimum usage of the heat produced during combustion.
