ABSTRACT:
The device for monitoring the combustion state of each cylinder is provided in a multi-cylinder engine and determining if combustion abnormality occurs in the cylinder. The misfiring determining circuit compares an engine speed of a previous interval with that of a current interval, calculates the speed variation of a cylinder between both intervals, and determines the misfiring level by comparing the variation with the misfiring determining level. A cylinder misfiring time counting circuit counts the misfiring time of each cylinder and informs a cylinder misfiring time calculating circuit of the counting result. The cylinder misfiring time calculating circuit serves to average the misfiring time. A cylinder abnormal misfiring determining circuit compares the average misfiring time with a predetermined misfiring time maximum value for detecting the abnormal misfiring in each cylinder.
