Detecting internal combustion engine misfires involves combining two successive ignition segments to form summation segment and defining revolution rate gradient from two successive summation segments

摘要

The method involves evaluating a revolution rate gradient defined by two successive ignition segments (ZS1-ZSn), whereby one segment is associated with a crankshaft angle range in which the associated cylinder starts the working cycle by igniting the mixture. It involves combining two successive ignition segments to a summation segment (tsh) and defining the revolution rate gradient from two successive summation segments.
