近年来,以柴油机为动力不但在重型载重汽车上,而且在轻型载重汽车上也正在不断发展。由于柴油机使用的燃料比汽油机更为经济,因而在广大农村深受用户欢迎,为了改善柴油汽车的制动性能,我们采用了带真空泵的交流发电机,即在发电机后端安装有真空泵,作为汽车真空加力制动系统中真空动力的来源。真空泵及其装有的单向阀与汽车的真空增压 In recent years, not only diesel engines have been used on heavy duty trucks but also on light duty trucks. Because diesel fuel is more economical than gasoline engine, it is widely welcomed by users in rural areas. In order to improve the braking performance of diesel vehicles, we use a vacuum generator with a vacuum pump installed at the rear of the generator as a The source of vacuum power in automobile vacuum afterburner system. Vacuum pump and its equipped with one-way valve and the car’s vacuum booster
