How Many Horsepower is a Four-Stroke Engine?

[MakaylaDella]

Four-stroke engines produce 5.36 horsepower. Characteristics of Stroke: Four-stroke engines utilize valves, which are operated via a timing chain (small chain) driven by the crankshaft timing gear. This timing chain then drives the camshaft to control the opening/closing of the valves. Compared to two-stroke engines of the same displacement, four-stroke engines offer better fuel efficiency, although two-stroke engines generally deliver higher power output. Working Principle of Stroke: To generate power, an engine must first intake a mixture of fuel and air into the cylinder. This mixture is then compressed and ignited to produce thermal energy. The expanding gases act as the working medium, pushing the piston and connecting rod to rotate the crankshaft, thereby converting thermal energy into mechanical energy. Finally, the exhaust gases are expelled from the cylinder. This completes one working cycle of the engine.
