These are heavy engines than the 2-stroke engines. They are relatively easy to repair and maintain. These engines are famous because of their high reliability and efficiency. The 4-stroke engines are most commonly used in motorcycles, automobiles, and other vehicles, as well as in generators and other machinery. Therefore, it belongs to the category of the reciprocating engine.Ī four-stroke engine completes a power cycle after the completion of two revolutions of the crankshaft or 4 strokes of the piston. It converts the thermal energy of the fuel into useful mechanical work due to the upward and downward movement of the piston. What is a Four-Stroke Engine?Ī 4-stroke engine is an IC engine that uses four strokes of the piston to complete a working cycle. This article explains the 4-stroke engine working, types, components, and applications. The piston reciprocates inside the engine cylinder. This engine completes a power cycle in four strokes of the piston. A four-stroke engine is a famous type of internal combustion (IC) engine.
