酒精—柴油乳剂及溶液的应用试验,是作为广泛基本代用燃料试验方案的一部分。本文研究了作为中速柴油机的一种辅助燃料——酒精,在一台两缸二冲程试验样机中的应用。对稳定的或非稳定的甲醇—柴油乳剂及乙醇—柴油乳剂两者均作了试验。除此之外还对无水酒精—柴油溶液的应用作出了评价。乳剂及溶液中最大酒精含量,由于柴油含量百分比的降低受限于发动机的爆震,发动机的功率和热效率在高、中速范围内稍低于原纯柴油的水平,但在不稳定乳剂和乙醇
The application of alcohol-diesel emulsions and solutions was tested as part of a broad basic alternative fuel testing program. This paper studies the application of a kind of auxiliary fuel, alcohol, as medium speed diesel engine in a two-cylinder two-stroke test prototype. Both stable and non-stable methanol-diesel emulsions and ethanol-diesel emulsions were tested. In addition, the application of anhydrous alcohol-diesel solution was evaluated. The maximum alcohol content in emulsions and solutions is somewhat lower than that of virgin diesel at high and medium speed due to engine detonation due to a decrease in the percentage of diesel fuel but with unstable emulsions and ethanol
