摘要： The invention relates to a method for monitoring a sensor unit (20) that is arranged in the exhaust gas region of an internal combustion engine (10). According to the invention, a sensor temperature (31, 32) is directly or indirectly determined by the sensor unit (20), and is compared to an exhaust temperature (33) that is determined by a further sensor unit and/or to model variables and/or to defined threshold values, whereby a dismounting and/or an inappropriate mounting of the sensor unit is indicated. The invention further relates to a device for monitoring a sensor unit (20) arranged in an exhaust region of an internal combustion engine (10), the sensor unit being used to directly or indirectly determine a sensor temperature (31, 32) which can be compared to an exhaust temperature (33) that is determined by a further sensor unit and/or to model variables and/or to defined threshold values in an engine control unit (14), wherein a malfunction entry and/or a warning signal can be derived from said comparison.

摘要： When a measurement trigger which is outputted at an every predetermined time after start of an engine is detected, a sensor outputting a signal in relation to concentration of a liquid reducing agent on the basis of a characteristic of heat transmission between two points apart from each other within the liquid reducing agent storage tank is triggered to measure concentration of the liquid reducing agent. Each of the number of times of determination of no liquid reducing agent, that is, the number of times concentration is successively determined to be equal to or higher than an upper limit threshold, and the number of times of determination of a solution of a different kind, that is, the number of times concentration is successively determined to be equal to or lower than a lower limit threshold is counted. When the number of times of determination of no liquid reducing agent becomes equal to or larger than the predetermined value, it is determined that no liquid reducing agent remains. When the number of times of determination of a solution of a different kind becomes equal to or larger than the predetermined value, it is determined that the liquid reducing agent is a solution of a different kind. When the number of times of determination of no liquid reducing agent and the number of times of determination of a solution of a different kind is less than the predetermined value, it is determined that the liquid reducing agent is correct one.

摘要： The invention is directed to a method for monitoring the quality of selective catalytic reduction agents, in particular for monitoring the quality of NH 3 producing reagents, such as urea solutions. The method of the present invention allows for determining the equivalent NH 3 concentration of any selective catalytic reduction reagent that forms NH 3 upon heating. Subsequently, the amount of injected reagent can be adjusted to the measured equivalent NH 3 concentration in order to optimise the NO x reduction.

摘要： Tax has become increasingly imposed one or more of harmful substances such as carbon dioxide, nitrogen oxides, sulfur oxides, and hydrogen carbides exhausted from a vehicle according to their amounts so as to heighten driver’s consciousness of emission and to promote environmental protection. An emission amount report device includes a sensor (40), a CPU (22), a ROM (26), a display (42), and a communication unit (30). The sensor (40) detects the amount of each harmful substance. From the ROM (26) storing information on tax according to emission amount, the CPU (22) obtains the tax information. The display (42) displays the obtained tax value corresponding to the detected emission amount. The CPU (22) carries out a tax payment procedure through the communication unit (30) by sending the information on the emission amount to a server (34) of the government office.
