How does compression ratio affect horsepower

A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to be reached with less fuel, while giving a longer expansion cycle, creating more mechanical power output and lowering the exhaust temperature. WebThe effect of compression ratio on the engine cycle is shown in Figs 16.12 and 16.13. It can be seen that a higher compression ratio gives a higher peak pressure, but has little effect …
