METHOD AND DEVICE FOR MONITORING A PARTICLE FILTER IN THE EXHAUST LINE OF AN INTERNAL COMBUSTION ENGINE |
摘要 |
<p>A device for monitoring an operating mode of an element used for aftertreatment of exhaust gases from an internal combustion engine and to an associated method. The device includes a controller configured to receive a signal that represents a characteristic magnitude of the exhaust gases downstream of the exhaust gas aftertreatment element. In addition, the controller can receive a signal that represents engine deceleration and is configured to increment a deceleration counter with each deceleration. The controller also includes a failure counter that is incremented when a variation in the above-mentioned measured magnitude is detected during a deceleration, the controller establishing a diagnostic criterion that is a function of the two counters. The controller triggers a fault signal if the diagnostic criterion exceeds programmed limits.</p> |
