A misfire detection study on a prechamber equipped spark ignition gas combustion engine is presented. The study shows that the logarithm of the absolute valued ion current can be linearly weighted in order to detect misfire over a broad load range with only one threshold. Results also show that a very low complexity misfire detector can achieve good performance when a linear weighting technique is applied to the squared rotational speed samples. The detection performance based on the combination of rotational speed and ionization measurements is also presented.
