  • Fuel injection system for an internal combustion engine
    Patent number: 8371267
    Abstract: The invention relates to a high-pressure fuel pump comprising a drive shaft supported by bearings, and fuel flows through the bearings in a forced manner in such a way that the mechanical and thermal load-carrying capacity of the bearings, and thus the entire high-pressure fuel pump, is significantly increased.
    Type: Grant
    Filed: May 8, 2006
    Date of Patent: February 12, 2013
    Assignee: Robert Bosch GmbH
    Inventors: Marcus Kristen, Achim Koehler, Sascha Ambrock, Walter Fuchs, Dietmar Ottenbacher, Bertram Schweitzer, Christian Langenbach, Joerg Wuerz, Saban Akmese, Marco Lamm, Karl-Heinz Traub

  • Method and device for control of the fuel injection in an internal combustion engine
    Patent number: 6823832
    Abstract: In a method and a device for controlling the injection of fuel into an internal combustion engine, a distinction is made at least between a first state and a second state. Immediately before the transition from the first state to the second state, the injection data is altered so that the emissions, in particular the production of noise, are gradually made to approximate the emissions in the second state.
