60年代末期,苏联中央油泵油嘴科研所研制成了375型汽油机用电拧汽油喷射的试验装置(见图1)。装有该装置的375型汽车的行车试验证实,可显著地改进汽车的指标。例如,带挂车的这种汽车加速时在同一时间的车速,比不带挂车的汽化器式发动机汽车快16～20％,而加速到55km/h的时间却比后者缩短43～48％。换句 In the late 1960s, the Soviet Union central pump nozzle research institute has developed a test apparatus for gasoline-powered gasoline jetting 375 gasoline engine (see Figure 1). The driving test of the 375 car with the device confirmed that the car’s specifications could be significantly improved. For example, a car with a trailer accelerates at the same time as a vehicle with a speed 16 to 20% faster than a carbureted engine without a trailer, and accelerates to 55 km / h 43 to 48% less than the latter.
