| 摘 要： | 测量并分析了由生物燃料、自来水和市售的93#汽油组成的2种配比的混合燃料发动机的燃料经济性能、动力性能、怠速时的排放性能.结果表明:与燃烧93#汽油相比,发动机燃烧混合燃料时,怠速时的HC和CO排放显著下降;混合燃料发动机的燃油消耗率在全负荷且转速小于 2 500 r/min的运转条件下降低,在全负荷且转速大于 2 500 r/min的运转条件下升高;在全负荷运转条件下混合燃料发动机的最大转矩下降约 6%、最大功率下降约7%,并且发动机的转矩随转速的增加而迅速降低.

| Abstract: | The investigation and analysis of power performance, economic performance and idle emission axe carried out on a type 1-4 spark ignition engine burning two different ratio of mixed oils which are made up of No.93 gasoline, vegetable oil, water and emulsion. The results indicate that (1) When burning mixed oil, the CO and HC emission concentration clearly decreases compared with burning gasoline at idle running condition. (2) When burning mixed oil, the oil consumption rate decreases compared with burning gasoline at full load running condition of engine at the speed of less than about 2 500 r / mm; At full load running condition of engine at the speed of larger than 2 500 r / mm, the oil consumption rate increases. (3) When burning No.1 mixed oil, the maximum torque and power of the engine respectively decrease by 6% and 7% compared with burning gasoline at full load running and the engine torque is rapidly decreasing with engine speed increasing. |
