How does stroke length affect horse power?

Answer 1

Stroke length in an engine refers to the distance the piston travels within the cylinder. A longer stroke typically allows for a larger displacement, which can lead to more power generation, as it increases the volume of air and fuel mixture that can be combusted. However, it also can affect engine speed and efficiency, as longer strokes may limit the engine's ability to rev high compared to shorter strokes. Ultimately, the relationship between stroke length and horsepower is influenced by various factors, including engine design and tuning.
