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. daily charme white chrome powderWeb15 de nov. de 2024 · Designs with long crank strokes relative to their bore diameters tend to also have high compression ratios.
