  • Procedure for determining the injected fuel mass of a single injection and device for implementing the procedure
    Patent number: 8290687
    Abstract: A method for determining a fuel mass of a single injection that has been injected into at least one combustion chamber of a combustion engine with at least one injection under high pressure. The method includes determining a correction variable for the single injection with the aid of a comparison of a measure for the actual amount of the injected fuel of at least one test injection, which takes place due to a measure for a default nominal amount of a desired single injection, and a measure for the nominal amount of the test injection. The method additionally includes executing a plurality of timely directly successive test injections.

  • Method and device for checking for leakage in a fuel injection valve of an internal combustion engine
    Patent number: 7937988
    Abstract: In a method and a device for testing for leakage in a fuel injection valve of an internal combustion engine, a temperature quantity is determined that characterizes the temperature of at least a part of the fuel injection valve. On the basis of this temperature quantity, the presence of a leak is inferred.
