柴油机电子控制系统的发展 摘要：柴油机是迄今为止热效率最高的热动力机械，柴油机的发展水平一直是车辆发展水平的重要标志，大力发展柴油机对于节约能源和解决温室效应的问题具有重要意义。由于世界石油危机和严重的环境污染，柴油机面临着日趋严格的排放法规和降低油耗等要求，采用电子控制技术是使柴油机同时满足各种要求的有效手段。柴油机的结构比较复杂，尤其是新兴的电子控制技术，对于广大汽车驾驶与维修人员来说有着十分重要的意义。本文介绍了柴油机电子控制系统中各种技术的控制原理、应用特点以及柴油机电子控制系统的发展趋势和未来的研究方向。 关键词：柴油机 电子控制 发展  Development of diesel electronic control system Abstract：Diesel engine is by far the highest thermal efficiency thermodynamic machinery, the development level of diesel engine has been the important symbol of the levels of vehicle development, vigorously develop diesel engine to save energy and solve the problem of the greenhouse effect is of great significance. Due to world oil crisis and serious environmental pollution, diesel engine is faced with increasingly stringent emission regulations and reduce fuel consumption and other requirements, using electronic control technology is to make the diesel engine at the same time meet the requirements of various effective means. The structure of the diesel engine is more complex, especially the emerging of electronic control technology, for the broad masses of vehicle driving and maintenance personnel has very important significance. Diesel engine electronic control system were introduced in this paper the control principle, the application characteristics of the various technologies and the development trend of diesel engine electronic control system and the future research direction.
