摘　　要：结合甲醇燃料的理化特性,分别在495Q和JT468Q汽油发动机进行了燃用高比例M85甲醇汽油燃料和全甲醇燃料的对比试验。试验结果表明:直接燃烧定比例甲醇燃料时,功率和扭矩都略有提高;提高压缩比后,功率和扭矩都大幅度提高,燃油消耗也大幅度降低、排放明显改善。Combining with the physical and chemical properties of methanol, the compared experiment where the methanol M85-petrol fuel and methanol fuel were separately used in the vehicle petrol engines 495Q and JT468Q was done. Experiment results show that there is a little bit improvement of power and torque when using methanol M85-petrol fuel and methanol fuel directly; but after increasing the compression ratio, the power and torque increased greatly, meanwhile to a great extent the consumption of fuel cut down and the emission was improved.
