Abstract: Emergency fuel plays an important role in oil supply during war time. A research of blending gasoline in diesel fuel with various proportions was carried out to analyze the physicochemical properties of the mixed fuels and to evaluate their engine test performance. It was found that diesel fuel blended with a certain amount of gasoline could be used as emergency diesel fuel, yet it could not be used for long since the engine power, twisting moment couple and average eruptive pressure were significantly affected, resulting in poor engine power performance, increase of fuel consumption and etc.

Key words: diesel fuel, emergency, engine, gasoline
