5, machine-driven electronic control system pump nozzle

At present the most complete development of the Electronic Control Unit Injector system is electronically controlled machine-driven pump nozzle systems, such as Detroit (De-troit) DDEC-engine company's electronic control pump nozzle, Germany's Bosch PDE2 7, and PDE2 8 - - Pump nozzle, the U.S. company's electronic control Carterpillar pump nozzle, the United Kingdom L ucas CAV EUI-based company's electronic control, such as pump nozzle. The injection pressure of existing products as much as 1 50 MPa, scientific research on the use of diesel has been as high as 2 0 0 MPa, or even higher injection pressure of the pump nozzle systems. Machine-driven electronic pump nozzle systems in foreign countries have Access to the full development, from less than 1 L single-cylinder displacement of small single-cylinder diesel engine emissions to the L to a few of the heavy-duty diesel engines have been used satisfactory results.
