Experimentation Investigate of Gasoline Engine Emergency Alternative Fuel

Abstract

This paper has integrated various methods such as engine bench test and actual road test, etc. to conduct a feasibility study on the emergency alternative fuel of gasoline by mixed jet fuel and gasoline. The research is divided into three parts. The first step is to mix the jet fuel and gasoline in different proportions and to analysis physicochemical properties. The study shows that both the evaporability and anti-knock quality decrease after mixing jet fuel with gasoline. The second step is to make bench test on the external characteristics and load characteristics with CA20 made use of so as to study the influences of the jet fuel to the dynamic performance and economical efficiency of the engine. The result shows that while the mixing proportion increases, the engine power decreases and the fuel consumption increases gradually. When the proportion reaches 40 %, the engine power drops by 5.3 to 11.7 %, the fuel consumption rises by an average of 3.8 %,The third step is to make a test on actual use for 1,000 km in order to study the adaptability of the jet fuel to the gasoline cars making use of blending fuel with 40 % jet fuel mixed in. The result shows that the lubricating oil dilution and exhaust emissions of engine become worse. All of the above studies show that as for the gasoline engine, the mixed oil can only be used as emergency alternative fuel due to its harm to the engine.
