WHAT IS MISFIRE PHENOMENON? Misfire is an undesired loss of flam which is triggering form different causes: Ignition problems: Defective ignition coil (hardware); dirty or old spark plug Injection problems: Defective Injector (hardware); Fuel pump failures; Short circuit in wiring harness Mechanical Problems: Loss of compression, valve terminals, poor carburation, extremely rich or lean mixture Some side effects of misfires: Overheating / destruction of the catalyst Increase of Emissions (mostly HC) Morgan Le Cossec 9th AVL Calibration Symposium 04 11 월 2015 4
FUNCTION PRINCIPLE Segment time [µs] Cyl #1 Cyl #2 Cyl #3 Cyl #4 Cyl #1 Cyl #2 Cyl #3 Cyl #4 Misfire detection Engine Roughness [µs] Morgan Le Cossec 9th AVL Calibration Symposium 04 11 월 2015 5
TEST PRINCIPLE An external function inside the ECU is activated via Calibration in order to generate the misfire patterns. The time between each event is necessary to cold down the catalyst. This measurement procedure has to be performed for all the operative points. 4 th 12 35 ST nd rd th Phase: Stabilization Generation paired Continuous Single opposite the operative cylinder Misfire cylinder Misfire event misfire point misfire on on (load one and each cylinder (Cylinder engine cylinder 1&3 0&1 speed) and consecutively and Cylinder 2&0) 2&3) Morgan Le Cossec 9th AVL Calibration Symposium 04 11 월 2015 6
