An Article about Four Stroke Engine

A four-stroke engine is a type of internal combustion engine that utilizes four strokes to complete a single operating cycle. The four strokes are known as intake, compression, combustion, and exhaust. This type of engine is widely used in automobiles, motorcycles, and other types of vehicles, as well as in various industrial and power generation applications.

During the intake stroke, the piston moves downward, creating a vacuum that draws air and fuel into the combustion chamber. The intake valve is open during this stroke, allowing the air-fuel mixture to enter the chamber. Once the piston reaches the bottom of the stroke, the intake valve closes.

During the compression stroke, the piston moves upward, compressing the air-fuel mixture that was drawn in during the previous stroke. The compression increases the pressure and temperature of the mixture, making it more combustible. Both the intake and exhaust valves are closed during this stroke.

During the combustion stroke, a spark plug ignites the compressed air-fuel mixture, causing it to rapidly expand and push the piston downward. This creates the power that is used to drive the vehicle or power generation equipment. Both the intake and exhaust valves are closed during this stroke.

During the exhaust stroke, the piston moves upward again, pushing the exhaust gases out of the combustion chamber and into the exhaust system. The exhaust valve is open during this stroke, allowing the gases to exit the engine. Once the piston reaches the top of the stroke, the exhaust valve closes, and the cycle begins again with the intake stroke.

One advantage of the four-stroke engine is its efficiency, which is achieved through a more complete combustion of the air-fuel mixture. It also produces less pollution than other types of engines, due to its effective exhaust system. However, the four-stroke engine can be more complex and expensive to manufacture than other engine types, and it requires regular maintenance to ensure its proper function.

Overall, the four-stroke engine is an important technological advancement that has revolutionized the transportation industry and has become a key component of modern society
