摘要： A method of predicting the temperature of a resistive heating element in a heating system is provided. The method includes obtaining resistance characteristics of resistive heating elements and compensating for variations in the resistance characteristics over a temperature regime. The resistance characteristics of the resistive heating element include, but are not limited to, inaccuracies in resistance measurements due to strain-induced resistance variations, variations in resistance due to the rate of cooling, shifts in power output due to exposure to temperature, resistance to temperature relationships, non-monotonic resistance to temperature relationships, system measurement errors, and combinations of resistance characteristics. The method includes interpreting and calibrating resistance characteristics based on a priori measurements and in situ measurements.

摘要： A method and system is disclosed to test for a proper functioning of a selective catalytic reduction system of an internal combustion engine. The engine is operated at idle speed and a functionality check of the pressure sensor is executed. The engine is operated to increase an exhaust gas temperature in the exhaust pipe upstream of the catalyst and a functionality check of the pump is executed. A functionality check of the injector is executed after the functionality check of the pump and once the exhaust gas temperature has reached a predetermined target value thereof. A functionality check of the supply conduit is executed after the functionality check of the injector. The selective catalytic reduction system is identified as functioning properly when all of the functionality checks yields a positive result or malfunctioning when any one of the functionality checks yields a negative result.

摘要： The present invention is intended to detect insulation failure of an EHC. In the invention, a heat generation element of the EHC is electrically insulated by an insulating member. Then, a determination as to whether insulation failure has occurred is made based on an insulation resistance value of the insulating member at the time when an amount of water absorption in the insulating member is smaller than a predetermined amount of water absorption and when an amount of PM deposition in the insulating member is smaller than a predetermined amount of PM deposition, a change in the insulation resistance value of the insulating member at the time when the amount of water absorption in the insulating member decreases from an amount equal to or larger than the predetermined amount of water absorption to an amount smaller than the predetermined amount of water absorption, and a change in the insulation resistance value of the insulating member at the time when the amount of PM deposition in the insulating member decreases from an amount equal to or larger than the predetermined amount of PM deposition to an amount smaller than the predetermined amount of PM deposition.

摘要： A control device is provided for controlling an electrically-heated catalyzer of an internal combustion engine. Electric power generated by an alternator driven by the engine is supplied to the electrically-heated catalyzer. At least one electrical parameter dependent on the electric power supplied to the electrically-heated catalyzer is detected. It is determined that the electrically-heated catalyzer is abnormal when the at least one electrical parameter falls outside a predetermined range. The predetermined range is changed according to the rotational speed of the engine detected by an engine rotational speed sensor.
