    摘要: The invention relates to a method for combustion misfire detection and cylinder equalization in a multi-cylinder internal combustion engine having knock control. In the method, rough-running values are individually determined for each cylinder by measuring segment times with each crankshaft rotation. The segment times include the times corresponding to the piston movement of each cylinder to be measured in which the crankshaft passes through a corresponding circular-segment angular region. Thereafter, the determined rough-running values are compared to a threshold value in a desired value comparison and, on the basis of the deviation between the determined rough-running values and the desired value, cylinder-individual equalization factors (that is, correction factors) are computed in an evaluation unit for the change of injection times or ignition time points of the individual cylinders. It is provided that the computed equalization factors (GL1) for the change of injection times or the ignition time points or the charge serve as the basis for the determination of a rough-running increase value (LUTcorrected) effected by the change and that, with the determined rough-running increase value (LUTcorrected), a computation of a corrected rough-running value (dLUT) takes place. The corrected rough-running value (dLUT) is utilized for the computation of the final equalization factor (GL2) for influencing injection times or ignition time points or the charge.

    摘要: An internal combustion engine has at least one combustion chamber which may be closed by an intake valve, at least one air intake port which leads to the intake valve, and a fuel injection device which in association with the at least one combustion chamber has a first injector and a second injector for the metered injection of fuel into at least one intake port. To achieve significantly improved mixture preparation and combustion of the fuel-air mixture in the combustion chamber, the two injectors are configured such that the first injector injects a widely divergent spray cone having a large cone angle, and the second injector injects an only slightly divergent spray cone having a much smaller cone angle.

    摘要: The functionality of the device for variably adjusting the cylinder compression ratio can be monitored easily, and without a special sensor, by ascertaining the running irregularity of the internal combustion engine both before and after controlling the device for changing the cylinder compression ratio; and by comparing the two running-irregularity values to each other, in order to determine if the runningirregularity has changed. A change in the running irregularity is an indication that the device for variably adjusting the cylinder compression ratio is functioning correctly.
