Diagnosis performing method for e.g. tractor-trailer, involves comparing minimum delta of inlet and outlet pressure in memory with minimum period of time to determine whether sensor is accurate

The method involves determining pressure from one of an inlet and an outlet, when an engine (14) i.e. diesel engine, is one of low/high engine speed and low/high engine torque. One of the inlet and outlet pressure between the low engine speed and torque is compared with one of the inlet and outlet p...

Zusammenfassung:	The method involves determining pressure from one of an inlet and an outlet, when an engine (14) i.e. diesel engine, is one of low/high engine speed and low/high engine torque. One of the inlet and outlet pressure between the low engine speed and torque is compared with one of the inlet and outlet pressure at high engine speed and torque. Minimum delta of the inlet and outlet pressure of a memory e.g. ROM (102), of an electronic control unit (ECU) is compared with a minimum period of time to determine whether a sensor is accurate. Es wird ein Verfahren zum Prüfen der Funktionstüchtigkeit der Komponenten eines Dieselpartikelfiltersystems auf der Basis der Motorgeschwindigkeit, des Motordrehmoments und des Einlass- und Auslassabgasdrucks an dem Dieselpartikelfilter angegeben. Verschiedene Sensorsignale werden mit kalibrierbaren Werten in einem Speicher verglichen, um zu bestimmen, ob das Dieselpartikelfiltersystem funktionstüchtig ist.
