FOUR (4) STROKE CYCLE ENGINES. A four-stroke cycle engine is an internal combustion engine that completes one cycle through four piston strokes: intake, compression, power, and exhaust, requiring two crankshaft revolutions (720°). This type of engine is common in small applications. Intake Stroke-The piston moves down, creating low pressure that allows the air-fuel mixture to enter the combustion chamber through the open intake valve, which closes after the cylinder fills. Compression Stroke- Th

How Does an Inline 4 Engine Work? 😍⚙️ A straight-four engine (also referred to as an inline-four engine) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with s
