3月28日,无锡油泵油嘴研究所副总工程师宋国民在接受《商用汽车新闻》记者采访时表示,随着我国排放法规的提升,高压共轨系统的推广势在必行。宋国民表示,共轨系统通过ECU对喷射压力、燃油分配、喷射时间和喷射速率进行控制,从根本上实现了压力建立和油量计量的分离,强化了喷油参数的全面独立掌控,更利于发动机的燃烧控制。"共轨系统在较低发动机转速下能提供很高的燃油压力,并可对每个气缸和每种工况进行工作性能优化。电控共轨喷射系统可实现喷油规律、形状的控制,灵活地为后处理装置再生提
On March 28, Song Guomin, deputy chief engineer of Wuxi Fuel Injection Research Institute, said in an interview with Commercial Vehicle News that with the promotion of China’s emission laws and regulations, the promotion of high-pressure common-rail system is imperative. Song Guomin said that the common rail system through the ECU on the injection pressure, fuel distribution, injection time and injection rate control, from the fundamental realization of the pressure to establish and the separation of fuel metering, fuel injection parameters to strengthen the comprehensive independent control, more conducive to Engine combustion control. Common rail systems provide high fuel pressure at lower engine speeds and optimize performance for each cylinder and for each operating condition. Electronically controlled common rail injection systems provide fuel injection laws and shape control , Flexibility to reprocess the post-processing device
