摘要： [Objective] To provide a particulate detection system which can properly detect the presence/absence of an anomaly of particulate collection characteristics of a filter disposed upstream of a sensor.
[Means for Solution] A particulate detection system 10, 1010, 2010 detects the amount M of particulates S contained in filtered exhaust gas FEG which is a portion of exhaust gas EG flowing through an exhaust pipe EP of an engine ENG mounted on a vehicle AM and which has passed through a filter DPF and is discharged to the outside of the vehicle. The particulate detection system 10, 1010, 2010 includes a sensor 100 disposed on the downstream side DLL of the filter DPF; a sensor circuit section 400, 500, 1500, 2500 which drives the sensor and obtains in real time a sensor output Ss corresponding to the volumetric particulate amount of the particulates contained in the filtered exhaust gas; and a computation section 500, 1500, 1600, 2500 which computes a distance particulate amount MD, MDW, MDN, MD(m), MDW(m), MDN(m) which is the weight or number of the particulates discharged per unit travel distance on the basis of the sensor output Ss, Ss(n) obtained by the sensor circuit section, travel distance Dd, Dd(m), Dr of the vehicle, and flow rate Fd, Fd(n) of the exhaust gas.

摘要： An exhaust gas purification system includes a feedforward controller 47, a feedback controller 49 outputting a correcting variable for achieving a target temperature of DPF 7, and a variable adding unit 51 that adds the correcting variable output from the feedback controller 49 to a basic variable output from the feedforward controller 47 to compute a manipulated variable. The system further includes either one of an integrator resetter 55 that resets the integral value of an integrator that forms the feedback controller 49 when the amount of exhaust gas has suddenly dropped, and a basic variable calculating unit that calculates the basic variable to be output from the feedforward controller based on a signal representing the flow rate of exhaust gas.

摘要： In an internal combustion engine, a hydrocarbon feed valve (15), NO x storage catalyst (13), particulate filter (14), and electric resistance type sensor (29) are arranged in an engine exhaust passage in this order from an upstream side. The electric resistance type sensor (29) generates an output value corresponding to the amounts of deposition of particulate matter and hydrocarbons which are contained in the exhaust gas and deposited at the sensor part thereof. From the change of the output value of the electric resistance type sensor (29), it is judged if the hydrocarbons have slipped through the NO x storage catalyst (13) and if the particulate matter has slipped through the particulate filter (14).

摘要： The present invention aims to determine a failure of a DPF with higher accuracy. A diagnosis device comprises: a diesel particulate filter (DPF) (52) that collects particulate matter (PM) in an exhaust gas; a resistive type PM sensor (20) that is provided at a downstream of the DPF (52) and that detects the amount of the PM from the current flowing through the PM deposited between electrodes (22), and for which regeneration is possible that combusts and eliminates the deposited PM; an actual regeneration interval calculating unit (41) that calculates the actual interval from the completion of the regeneration of the sensor (20) to the start of the next regeneration; a PM slippage amount calculating unit (43) that estimates the amount of PM slippage in the exhaust gas that is slipped through the DPF (52) assuming the DPF (52) being normal; an estimated regeneration interval calculating unit (45) that calculates, on the basis of the PM slippage amount, an estimated interval from the completion of the regeneration of the sensor (20) to the start of the next regeneration; and a DPF failure-normal determining unit (46) that determines whether the DPF (52) has failed or is normal by comparing the actual interval to the estimated interval.

摘要： A diagnostic system for an internal combustion engine (1), the diagnostic system includes an electronic control unit (10). The electronic control unit determines that whether a predetermined condition is satisfied. The predetermined condition is a condition under which an amount of PM that separates from a filter is larger than or equal to a predetermined separation amount as a urea water-originated deposit once accumulated in the filter separates in gaseous form. When the electronic control unit determines that the predetermined condition is satisfied, the electronic control unit does not execute a diagnosis of a malfunction in the filter based on a filter differential pressure until a predetermined period elapses from the point in time at which it is determined that the predetermined condition is satisfied.

摘要： The invention relates to a method for determining a soot load (RB) of a particulate filter (18) that is connected downstream of an internal combustion engine (12), as a function of an amount of soot (RE) that has been introduced into said particulate filter (18). The invention also relates to a control device (30) which is configured to carry out this method, and to a motor vehicle (14) which comprises same. Determination of the amount of soot (RE) that has been introduced comprises the steps of detecting and taking into account such soot-emission-relevant events that cause, in a standardised operating cycle, a predetermined minimum soot emission amount from a total soot emission emitted by the internal combustion engine (12), said minimum soot emission amount of these soot-emission-relevant events being less than the total emitted soot emission. The amount of soot that has been introduced (RE) is preferably determined exclusively on the basis of such soot-emission-relevant events.
