介绍了柴油机特别是机车柴油机转速和功率调节系统的发展过程及目前所达到的水平，其中包括英国Brush公司对60型内燃机车柴油机功率调节系统的改进；指出机车柴油机目前已采用微型计算机进行转速和功率的调节和控制，即出现了所谓的发动机管理系统，这种管理系统不仅能根据实际运行要求对柴油机精确地进行转速和功率调节。还可以优化燃油喷射过程以及对柴油机的各种运行参数进行监控，其中包括对排放参数的控制。
The development process of the diesel engine, especially the locomotive diesel engine speed and power regulation system, and the level reached at present are introduced, including the improvement of the diesel engine power regulation system of the 60 diesel locomotive by British Brush Company. It is pointed out that the locomotive diesel engine has adopted the microcomputer speed and Power regulation and control, that is, the emergence of the so-called engine management system, this management system can not only be based on actual operating requirements of diesel engine speed and power regulation accurately. It also optimizes the fuel injection process and monitors various operating parameters of the diesel engine, including control of emission parameters.
