| titleOfInvention | Method for checking the function of a particulate filter |
| abstract | Method for checking the functionality of a particle filter (7) for filtering soot particles from exhaust gases of an internal combustion engine (3), wherein the particle filter (7) is arranged in front of an electrostatic particle sensor (9) with respect to the flow direction of the exhaust gas, comprising a first electrode ( 13) and a second electrode (15), wherein a gap (17) through which the exhaust gas flows is provided between the electrodes (13, 15) and the electrodes (13, 15) have a potential difference, the electrodes (13 , 15) accumulate soot particles and move to one of a pre-loading of the electrodes (13) with soot particles dependent residence time to the respective other electrode (15, 13), so that a current flow is generated, which serves as a sensor current as a measure of the amount of soot in the exhaust stream is measured, with the following to check the function of the particulate filter (7): - Determining an operating condition of the internal combustion engine (3), in which a reduction of an exhaust gas velocity in the gap (17) occurs; - Measuring a momentarily increased sensor current in the form of a Abschaltpeaks; - Comparison of the measured Abschaltpeaks with a for an intact particulate filter (7) expected Abschaltpeak, wherein a defective particulate filter (7) is closed when a difference between the measured Abschaltpeak and the expected Abschaltpeak exceeds a predetermined value. |
