The power stroke in an internal combustion engine involves work done on the crankshaft through the conversion of chemical potential energy into mechanical work.
The power stroke of an internal combustion engine is the stage where work is done by turning a crankshaft. During this phase, the air-fuel mixture is ignited, leading to a significant increase in pressure, and the gas exerts a force through a distance, resulting in work being done on the crankshaft.
In a simplified Otto cycle diagram for internal combustion engines, the path CD represents the power stroke where more work is done by the gas, leading to a net work output.
This process exemplifies the conversion of chemical potential energy into mechanical work within the engine, emphasizing the crucial role of the power stroke in driving the engine's operation.
