IC Engine and its classification

IC Engine

IC engines is a device which act as a Powerhouse of the automobile. IC engine is also known as the heart of the automobile. The IC engine converts the heat energy produced by the burning of a fuel into mechanical power through various parts so it is an assembly of a large number of parts which are used to do work and make the transfer of energy. This energy stored in the flywheel connected to the crankshaft. The flywheel translate this energy to the road wheels through transmission system. In this way the power system i.e. the engine sets the vehicle in motion.

IC engine usually stands for internal combustion engine it is said so because the Combustion of the fuel takes place inside the cylinder of an engine. Petrol, oil and gas engines are some of the general examples of internal combustion engines.Air or mixture of air and fuel is the working agent in these engines.
