What Does the Engine Gas Exchange Process Include?

[DiTeagan]

An engine operates through four strokes: intake, compression, power, and exhaust. The gas exchange process specifically refers to the exhaust and intake phases. Definition of Stroke: It refers to the movement of the engine piston from one end of the cylinder to the other. Engines are categorized into two-stroke and four-stroke, also known as two-cycle and four-cycle engines. Definition of Engine Cylinder: The cylinder block, also referred to as the engine block, serves as the main body of the engine. Cylinders are arranged within the block, which also contains water passages and mounting arrangements for various shafts. Early cylinder blocks were typically made of cast iron due to the underdeveloped technology for casting aluminum alloys at the time.
