High-Pressure Injection Pumps with Electronic Control for Heavy-Duty Diesel Engines 850170

Within the Robert Bosch Diesel Injection Pump Program, the MW and P pumps have a fundamental significance concerning medium-duty and heavy- duty engines.

These engines have developed considerably in the last years with regard to combustion efficiency and emission reduction. In order to reach these new targets, specific developments of the pump were necessary to realize injection pressure of 900 bar and 1200 bar for the MW and P pumps, respectively.

A further development emphasis of the past years was the development of a robust electronic governor concept to take advantage of this new technology.

The topics of the paper are:

Further development of the pump drivetrain and housing to cope with the difficulties inherent in producing 1000 bar.
Development of constant-pressure valves.
Preparation of the electronic governor concept for commercial vehicles.
Development results of the electro-magnetic and electro-hydraulic actuators.
