, electronically controlled with pressure-pump nozzle systems

In recent years, electronic control with pressure-pump nozzle of active research. Because it does not need to drive machinery and mechanical conditioning, it can not re-design of the diesel engine under the pump nozzle to play the advantages of companies such as the United States Caterpillar The electronic control with pressure-pump nozzle systems HEUI, the system's main features are: will be electronically controlled hydraulic and technology, according to the time control process and the jet spray pressure of the system's work has nothing to do with the engine speed, in a broad Conditions within the framework of maintaining high pressure fuel injection, the maximum injection pressure to reach 1 50 MPa; has injection rate controls, the initial supply period, the ignition delay period and the main jet fuel supply during the optimization of control ; Application of the diesel engine fuel injection system of the smoke particles and NOX emissions and responsiveness have been improved.

BKM companies from the United States in 1975 started to develop electronic control with pressure-pump nozzle, in 1983 a formal mass production. This servo fuel injection system to meet the 17 ~ 2 91 0 k W Diesel needs of the match, the maximum injection pressure up 160 MPa.

Japan's Komatsu other products is also available in electronic hydraulic pump nozzle KOMPICS company, Denso's common rail system ECD-U2, and Germany's Bosch common-rail diesel engine with electronically controlled pressure-spray systems.
