  • Method for assessing an injection behaviour of at least one injection valve in an internal combustion engine and operating method for an internal combustion engine
    Patent number: 9458809
    Abstract: A method for assessing an injection behavior of at least one injection valve of an internal combustion engine includes putting the internal combustion engine into a special operating mode defined by control parameters and operating the engine in the special operating mode during a diagnostic time period, at least one operating parameter of the internal combustion engine being determined at least during the diagnostic time period, and at least one quantity characterizing the injection behavior of the at least one injection valve being evaluated at least during a segment of the diagnostic time period and being evaluated on the basis of the at least one operating parameter.

  • METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE
    Publication number: 20120158271
    Abstract: A method for operating an internal combustion engine, in particular, of a motor vehicle. The internal combustion engine includes an injector having a nozzle needle for injecting fuel into a combustion chamber of the internal combustion engine, as well as an output stage component. A desired signal is specified for a lift characteristic of the nozzle needle. The injector is activated by the output stage component. A lift signal is ascertained that corresponds to the actual lift characteristic of the nozzle needle. An actual signal is ascertained from the lift signal. A deviation signal is ascertained in response to a deviation of the actual signal from the desired signal.
