<p>In an internal combustion engine provided with a flywheel damper, an operation range in which misfire detection is affected by the flywheel damper is set in advance. Whether or not an operation state of the engine (internal combustion engine) is within "the operation range affected by the flywheel damper (ranges A and C)" is determined (step ST3). When the operation state is within "the operation range affected by the flywheel damper", for example a cylinder specifying process specifying a misfiring cylinder is stopped (step ST4). By such processing, erroneous detection attributed to irregular rotation fluctuation behavior caused by the flywheel damper can be avoided, and misfire detection performance can be improved.</p> |
