摘要： In a method for determining a vibration-optimised adjustment of an injection device of an internal combustion engine, for each cycle of the internal combustion engine, a plurality of individual injections per cylinder is carried out by the injection device, each of which is defined by a relative injection moment and an individual injection quantity. A temporal course of a resulting pressure influenced by pressure waves is determined in a fuel guiding part, and the above-mentioned adjustment is determined by variation of the injection moment of at least one individual injection and/or the individual quantity, such that the adjustment is characterised by a temporal variation of the resulting pressure, which is reduced by an at least partially destructive interference between the cited pressure waves. A corresponding device can determine a vibration-optimised adjustment of an injection device, and an internal combustion engine may have such a device.

摘要： A method for approximating a stored pilot control map of a pressure control valve of a common-rail pump to the effective of pilot control map of the pressure control valve is presented. The stored pilot control map forms a desired pressure in the rail on a control current of the pressure control valve. The method includes the following method steps a) measurement of the pressure in the rail; b) determination of the control current of the pressure control valve; and c) adaptation of the stored pilot control map by a regression process that includes the pressure measured in step a) and control current measured in step b). In the course of a test run lasting 120 seconds (s) the control deviations (dp) of the desired pressure from the actual pressure in the pressure control valve could be substantially reduced.
