WebIf the compression ratio is too low, power will be reduced and emissions may increase. If too high, cylinder temperatures will increase, the fuel air mixture may ignite before it is … 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.
