未来高速直喷式柴油机的发展对发动机压力测量技术提出了新的更高要求。这方面的研究开发工作要求应用性能更加完善,或是完全新型的传感器进行燃烧压力和喷射系统压力测量。介绍的工作是应用一些新型传感器在共轨系统上进行的一系列高压测量和燃烧室压力测量,探索了适应未来柴油机技术发展的压力测量技术和对压力传感器的新要求。
The future development of high-speed direct injection diesel engine put forward new and higher requirements on engine pressure measurement technology. Research and development work in this area requires improved application performance, or a completely new type of sensor for combustion pressure and injection pressure measurement. The work presented is a series of high pressure measurement and combustion chamber pressure measurement carried out by some new sensors on the common rail system. The pressure measurement technology adapting to the future development of diesel engine technology and the new requirements for pressure sensors are explored.
