It is pointed out that when more methanol is used, the principle of equal heating values in each cycle must be observed and the orifice of carburetor should be increased in order to guarantee better power performance. It is shown that with adjusted ignition angle of advance, larger compression ratio and appropriate preheating of the mixture, better fuel economy can be a...             本文通过在475C-2和492Q汽油机上掺烧甲醇的试验研究,分析了掺烧甲醇时汽油机的动力性能及燃油经济性,指出在掺烧较多甲醇时,应根据每循环中混合气热值不变的原则,加大化油器的量孔,以保证具有较好的动力性能;指出调整点火提前角、提高压缩比以及适当预热混合气等,可以提高掺烧甲醇时燃油的经济性.文中还通过对小白鼠的试验,论述了甲醇的毒性,并对甲醇与汽油的混溶试验进行了一些研究. 文摘来源          For exploiting alternative fuels to petroleum, intensive research has been undertaken on the utilization of methanol and methanol-gasoline blend as fuel in 4-stroke I.

Meanwhile, the centane number and calorific power are reduced. Viscosity, however,has a little change. The vaporization characteristic of blend oil is satisfactory for diesel engine. The ignition delay, maximum cylinder pressure and emission of NO and HC are rais- ed. In addition, the fuel consumption is increased because the calorific power of blend oil is...             对两类直馏与催化裂化柴油所配制的八种不同比例的混合油进行测定和分析表 明，随含催化裂化油比例增加．密度增大；十六烷值和热值都降低；粘度变化不大； 蒸发性能基本满足柴油机要求；点火延迟期增长；爆压和压升率增大；油耗因热值减 小而增高；ＮＯ和ＣＨ的排放增加．比例大于４０％后，需采取适当的技术措施才 可使燃烧性能满足要求。 文摘来源   << 更多相关文摘         相关查询: polymer blend blend method blend products blend film blend refrigerant coal blend leaf blend iterative blend polymers blend blend transportation blend polymer blend interface  对查询结果不满意
