Study of diesels controlled technology on the base of MC68376

The development process of electronic control technique of diesel engines was reviewed. The proportional-integral-differential principles of the position electronic controlled is discussed. To feature of BF8L413F diesel engine and BOSCH-P8AE pump. The effects influcing the diesels' oil temperature & input air pressure were analysed. The diesels controlled system by adding pressure sensor and temperature sensor to improve BOSCH-P8AE pump properties and adaptabilities were discussed. Bench test for MC68376-based BF8L413F diesel with this electronic control system was carried out. The results of test showed that the properties of this system is better and this system has some application worthiness.
