Abstract
It is important to calculate engine roughness for misfire diagnostics based on crankshaft speed fluctuation. This paper studies the current misfire diagnostic method and the optimizing strategy based on Chery 447F engine. Engine misfire detection method based on crankshaft speed multiple filtering is presented. After test verification, the method can recognize single-cylinder´s and multi-cylinders´ misfires accurately without Fuel-Cut Self-Learning and Fuel-On Self-Learning.
