  • System and method for preventing overheating of a fuel pump
    Patent number: 8307810
    Abstract: A fuel injection system supplies fuel at high pressure to an internal combustion engine via at least two high-pressure fuel pumps and a high-pressure fuel distribution line. The high-pressure fuel pumps can operate in a first pump mode and a second pump mode, which differ in the amount of fuel that is pumped. A control unit alternately operates the high-pressure fuel pumps such that, during a first time period, at least one of the high-pressure fuel pumps is operated in the first pump mode and all other high-pressure fuel pumps are simultaneously operated in the second pump mode and such that, during a second time period, at least one of the high-pressure fuel pumps, which was operated in the second pump mode during the first time period, is operated in the first pump mode and the remaining high-pressure fuel pumps are simultaneously operated in the second pump mode.
