A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel …

3 days ago · An internal combustion engine operates by converting the chemical energy stored in fuel into mechanical work. The four-stroke engine is the most common design of this type, …

Aug 14, 2025 · Learn all about how four-stroke engines work, their main components, and why they matter in modern vehicles.

Apr 13, 2023 · There are typically four strokes involved in the operation of a four-stroke engine: intake, compression, power and exhaust. During the intake stroke, the piston moves …

At the peak of this cycle, the spark plug fires, igniting the compressed fuel-air mixture. This controlled explosion pushes the piston down with massive force in the power stroke, which is …

Nov 19, 2025 · Four-stroke cycle, principle by which most modern automobile engines function. As illustrated by the figure, while the inlet valve is open, the piston first descends on the intake …

A four-stroke engine is an internal combustion engine that converts fuel's chemical energy into mechanical energy through four distinct piston strokes: intake, compression, power, and exhaust.

A 4-stroke engine is an IC engine that uses four strokes of the piston to complete a working cycle. It converts the thermal energy of the fuel into useful mechanical work due to the upward and …

Nov 18, 2025 · This guide explains the four-stroke cycle, including intake, compression, power, and exhaust strokes, as well as key components like pistons, valves, and spark plugs. …

A visual diagram of the 4 stroke engine cycle, showing the intake, compression, power, and exhaust strokes. Understand how the engine works and the sequence of events that occur …
