    摘要: A method for controlling a compression-ignition internal combustion engine includes the following steps: predefining a setpoint combustion point for the compression-ignition internal combustion engine, predefining a calculation model for calculating a probable deviation of a future cycle of the internal combustion engine from the predefined setpoint combustion point while taking an ascertained actual combustion point of a completed cycle of the internal combustion engine into consideration, predefining a mean deviation for the internal combustion engine, operating the internal combustion engine for a first cycle and ascertaining an actual combustion point of the first cycle, calculating a probable deviation of a second cycle, which occurs after the first cycle, of the internal combustion engine from the predefined setpoint combustion point, comparing the calculated probable deviation of the second cycle to the predefined mean deviation, and ascertaining at least one operating variable for operating the internal combustion engine at least during the second cycle as a function of the comparison. In addition, a control device for controlling a compression-ignition internal combustion engine is described.

    摘要: A method for operating an internal combustion engine, especially an internal combustion engine that is operable, at least in a part-load range, in an operating mode with auto-ignition, in which, at an abrupt change in load and/or at a changeover between an operating mode with auto-ignition and an operating mode without auto-ignition, a parameter of the combustion process correlating with the combustion noise is adapted stepwise over a plurality of combustion cycles from a first parameter value before the abrupt change in load or the changeover to a second parameter value after the abrupt change in load or the changeover, by influencing a combustion position of the combustion process.

    摘要: A device and a method for actuating an injector in a fuel-injection system of an internal combustion engine are described. Using a first calibration method and based on a control parameter, an injector parameter which characterizes the injection process is determined. Starting from this injector parameter, a first feature is determined for calibrating the injector. A second calibration method determines a second feature for calibrating the injector, based on an engine parameter. The first calibration method is monitored on the basis of the second feature.
