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. daughters alexisWebMar 26, 2024 · Increasing compression ratio can have both positive and negative effects on turbocharger efficiency. On the positive side, increasing compression ratio can lead to higher engine efficiency, which means more power is produced for a given amount of fuel. bkw55.comWebJan 6, 2016 · Compression equals horsepower.
