奥地汽车公司最近发展了一种机械式汽油喷射装置,该装置以气体流量计测量发动机的进气量,并由机械式配油系统供油。其中气体流量计按定压阀(Stauklapqe)原理工作,靠转动定压阀来开关分配孔,燃油则从分配孔经平衡阀到达各个喷油咀。由于分配孔的开关特性良好,部分负荷下的燃油分配可达到空前的精确度。暖车和全负荷工况下,可以由进气压差来调节进气量以与供油加浓相匹配。用补加空气调节器调节空转时的进气量。调整定压阀可得到冷态起动用的加浓油量。该装置中还使用了电子调节元件,如λ探针。此装置已申请专刊。
Austrian Motor Company recently developed a mechanical gasoline injection device that uses a gas flow meter to measure the engine intake and is supplied by a mechanical fuel distribution system. Which gas flow meter according to the principle of constant pressure valve (Stauklapqe) work, by rotating the pressure regulating valve to open and close the distribution hole, the fuel from the distribution hole through the balancing valve to reach the nozzle. Due to the good switching characteristics of the distribution holes, the fuel distribution at part load can achieve unprecedented accuracy. Warm car and full load conditions, intake air pressure can be adjusted to adjust the amount of intake fuel enrichment and match. With additional air regulator to adjust the idle air intake. Adjust the pressure regulating valve can be used for cold start with the enrichment of oil. Electronic adjustment elements such as lambda probes are also used in the device. This device has been applied for a special issue.
