日本日野汽车工业公司开发出一种公共汽车用的柴油—电力混合式发动机,能有效地减少汽车黑烟的排放量。 这种新式发动机系统是由传统柴油机、装在柴油机飞轮壳内的电动机、特殊制动器、交流器、微电脑和铅酸电池所组成。当公共汽车行驶时,每逢制动,电动机充当发电机运行,这时从旋转车轮得到的 Hino Automobile Industry Co., Ltd. of Japan has developed a diesel-electric hybrid engine for buses, which can effectively reduce the emission of automobile black smoke. This new engine system is composed of a traditional diesel engine, a motor mounted in a flywheel housing of a diesel engine, special brakes, a commutator, a microcomputer and a lead-acid battery. When the bus is running, every time the motor is braked, the motor acts as a generator, and from the rotating wheels
