Abstract: A feasibility study of using mixed fuel of gasoline/jet fuel as emergency gasoline engine fuel was conducted. The properties and performance of the mixed fuel were evaluated by comprehensive approach including laboratory analysis, engine bench test and road test. Results show that by mixing jet fuel into gasoline, the volatility and anti-knock property of the mixed fuel decrease; with the increase of jet fuel mixing proportion, the power of gasoline engine reduces and the fuel consumption increases gradually. When the volume fraction of jet fuel reaches 40% in the mixed fuel, the engine power drops by 5.3%-11.7% and the fuel consumption increases by an average of 3.8%, at the meantime engine oil dilution and exhaust emission become worse. Thus for gasoline engine, the mixed fuel of gasoline/jet fuel could only be used as an emergency alternative fuel and with a volume fraction of jet fuel less than 40%, since it may be harmful to the engine.
