WebThe compression ratio may be higher in engines running exclusively on liquefied petroleum gas (LPG or "propane autogas") or compressed natural gas, due to the higher octane rating of these fuels. Kerosene engines … WebHowever, an excessively low effective compression ratio causes high unburned HC emissions and fuel consumption. For example, the compression ratio cannot be less than 5:1, as reported by Helmantel and Denbratt (2006).
