Principle of Four Stroke Engine (Petrol and Diesel)

The four-stroke engine is one of the most known internal combustion engines which is ideally implemented in the automobile industry. Such engines are usually adopted for bikes, cars, trucks, buses, and other automobiles while some of the motorbikes also go with the two-stroke engines. With the help of a four-stroke power engine, one power stroke is generated after every two cycles of the piston. The working principle of the Four-stroke engine is composed of the Intake stroke, compression stroke, compression stroke, power stroke, exhaust stroke, etc.

With the assistance of Intake Stroke, the piston ploys toward the bottom that will specifically increase the volume for the fuel-air mixture in the chamber. On the other side, in the process of Compression Stroke, the intake valve becomes close while the piston goes to the chamber that helps in compressing the fuel-air mixture greatly. Moreover, a spark plug is responsible to give the compressed fuel that will assist in the combustion process of the four-stroke engines. The power stroke is being used after the fuel arrives at the edge of the combustion and the heat liberated from combusting hydrocarbons boosts the pressure that becomes a reason to shift down the gas on the piston and thus the power output will be generated. You must have to note that when the piston goes to the bottom, the exhaust valve will free.
