Embodiment Construction

[0054] Time (time) is represented by an x-axis in a graph. Three different cases for determining the control parameters (case 1, case 2, case 3) are schematically represented above and below the y-axis. In the example shown, each involves the calculation of the injection time at which the fuel injector is controlled. Of course, other control parameters can also be calculated additionally or alternatively. In order to clearly distinguish three cases Situation 1, Situation 2 and Situation 3 through horizontal dividing lines C1, C2 and C3, wherein Situation 1 is shown above the dividing line C1, Situation 2 is shown between the dividing lines C1 and C2, and Situation 2 is shown between the dividing lines C1 and C2. Case 3 is shown between boundaries C2 and C3.

[0055] In the example shown, a fuel pressure FUP that increases linearly with time is applied to the fuel injector. This pressure is represented in the graph below the dividing line C3.

[0056] In the example shown a...

Abstract

The invention relates to a method for determining a control parameter for a fuel injector of an internal combustion engine. The problem of enabling more precise determination of the control parameter, even if the fuel pressure (FUP) present on the fuel injector varies, is solved in that the fuel pressure (FUP) present on the fuel injector during the injection (I1, I2, I1', I1'') is concluded while allowing for the time of the fuel pressure value detection and / or the crankshaft angle position of the internal combustion engine during the detection of the fuel pressure value, and that the control parameter is determined based on the fuel pressure (FUP) that was concluded. The invention further relates to a corresponding device.

Description

technical field [0001] The invention relates to a method for determining control parameters of a fuel injector of an internal combustion engine, in which method at least one fuel pressure value acting on the fuel injector is obtained, and in which method the fuel injection is determined taking into account the obtained fuel pressure value control parameters of the device. [0002] The invention also relates to a device for determining the control parameters of a fuel injector of an internal combustion engine, having a measuring device capable of obtaining at least one value of the fuel pressure acting on the fuel injector and having an evaluation device by which the obtained fuel pressure is taken into account Determine the control parameters of the fuel injector under the condition of the value. Background technique [0003] With increasing legal requirements regarding exhaust gas properties and requirements from vehicle manufacturers there is always a need for more precis...
