基于MC68376单片机的柴油机电控技术的试验研究

Study of diesels controlled technology on the base of MC68376

对国内外柴油机电控技术的发展态势进行了分析,阐述了柴油机燃油喷射位置式PID电子控制方法的原理。对基于MC68376单片机的柴油机燃油喷射电控系统的组成及其功能进行了研究。针对BF8L413F柴油机和BOSCH-P8AE喷油泵调速系统的特点,分析了进气压力和温度及燃油温度对电控柴油机性能的影响。台架试验结果表明,增加进气压力和温度及燃油温度等控制参数后,改善了电控柴油机的整体性能,能够满足实际车辆的使用要求。

The development process of electronic control technique of diesel engines was reviewed. The proportionalities graldifferential principles of the position electronic controlled is discussed. To feature of BF8L413F diesel engine and BOSCH- P8AE pump. The effects in fluking the diesels＇ oil temperature ＆ input air pressure were analyzed. The diesels controlled system by adding pressurizes or and temperature sense or to improve BOSCH2P8AE pump properties and adaptabilities were discus s ed. Bench test for MC683762bas ed BF8L413F dies el with this electronic control sys tern was carried out . The results of test showed that the properties of this sys tern are better and this system has some application worthiness.
