  • Diagnostic method for recognizing combustion misfiring in an internal-combustion engine
    Patent number: 5616858
    Abstract: In a diagnostic method for recognizing combustion misfiring in an internal-combustion engine, a map of characteristics, in which characteristic numbers dependent on load and on rotational speed are filed, is provided. One or more different diagnostic methods are selected by a diagnostic device depending on the respective characteristic number and allow as reliable information as possible of combustion misfiring for the respective load and rotational-speed range.

  • Method for recognizing irregular combustions in a cylinder of an internal combustion engine
    Patent number: 5503009
    Abstract: The speed for each cylinder of an internal combustion engine is detected at two crankshaft positions (z1, z2) of a cylinder and an irregular combustion is recognized when the gradient of the speed curve falls below limit value GW.

  • Method for recognizing abnormal combustions in the cylinder of an internal-combustion engine
    Patent number: 5394742
    Abstract: The speed for each cylinder is determined by means of two crankshaft positions z1, z2. The crankshaft positions z1, z2 are optimized in terms of the case of abnormal combustion. Abnormal combustion is recognized when, according to the selected definition of the speed difference .DELTA.T, a limit value GW is not reached or is exceeded.
