据英国研制一种以微处理机为主要部分的燃油供给量控制系统的人员称,有可能使大型柴油机动车辆节约达15％的燃料。这种命名为JMS的燃油控制装置是专为从事短途往返循环运输重型汽车,如公共汽车、自卸卡车和运土车而设计的。在这种车辆往返运行的条件下,司机为了克服车辆载荷的惯性,常常要大开油门,这使得一部分燃料未经燃烧就通过发动机而白白浪费掉,并且还会产生缕缕黑烟。 According to a British official who developed a microprocessor-based fuel supply control system, it is possible to save up to 15% on large diesel motor vehicles. This fuel control device, named JMS, is designed for short-distance round-trip transport of heavy vehicles, such as buses, dump trucks and earthmoving trucks. Under the condition of such vehicle running back and forth, in order to overcome the inertia of the load of the vehicle, the driver often opens the accelerator. As a result, a part of the fuel is wasted through the engine without being burnt and will generate a plume of black smoke.
