据了解,7月3日,国家863计划支持的“高压共轨重型柴油机关键技术研究”课题,取得阶段性成果。课题设计开发了喷射压力达到180MPa的高压共轨泵,满足要求的共轨管,在冷拖实验台上进行了性能试验,并在发动机上进行了台架试验验证,为高压共轨燃油系统关键零部件开发及关键技术研究奠定了良好的技术基础。随着国外柴油机电控技术的迅速发展,国内对电控喷油系统的研究也日趋重视。电控共轨系统是目前难度最
It is understood that on July 3, the national 863 plan to support “high pressure common rail heavy duty diesel engine key technology research ” project, and achieved initial results. Design and development of the jet pressure of 180MPa high-pressure common rail pump to meet the requirements of the common rail tube in the cold drag test bench carried out performance tests and bench tests on the engine for high pressure common rail fuel system key Component development and key technology research laid a good technical foundation. With the rapid development of foreign diesel engine electronic control technology, the domestic research on the electronic fuel injection system also pay more attention. Electronic control common rail system is the most difficult
