Abstract: A method for regeneration of a CDPF disposed in the exhaust stream of a diesel engine. The method includes a second phase operation following a first phase substantially as disclosed in the prior art. As the first phase ends, as indicated by a temperature sensor at the exit end of the CDPF, the temperature and oxygen content of the exhaust gas are increased at the entrance to the CDPF in an ensuing second stage. These increases cause oxidation of the soot remaining near the entrance and the sides of the CDPF, resulting in a cleaner and higher-capacity CDPF than is produced by a single-phase regeneration in the prior art. The sequential stages are implemented via an algorithm programmed into an Engine Control Module (ECM). A CDPF regenerated in accordance with the invention can have approximately 95% of its filtration capacity restored.

Abstract: The present invention concerns a method for sheathing an electrical conductor with an elastic sealing element. In the method, first a through-opening is produced in the sealing element with a first equivalent diameter. Next the through-opening which has been produced with a first equivalent diameter is expanded to a second equivalent diameter, in order to be able to introduce an electrical conductor into it. Then contraction of the through-opening which has been expanded to the second equivalent diameter is brought about, in order thus to obtain sealing off of the electrical conductor from the elastic sealing element.

Abstract: An occupant detection system, a controller for an occupant detection system and a method of detecting an occupant. The presence or absence of the occupant varies the dielectric properties of an area proximate to influence the electrical impedance of the electrode. The electrode impedance is determined based on based on the excitation signal frequency, the excitation signal magnitude, and the electrode signal magnitude, and thereby determine an occupant presence based on the electrode impedance. The excitation signal magnitude is adjusted to optimize the electrode signal magnitude. The electrode signal magnitude is optimized to be large enough to be accurately measured, but not so large as to cause excessive radiated emissions. The excitation signal magnitude may be adjusted for each excitation signal frequency so the electrode signal magnitude is optimized regardless of frequency.

Abstract: An occupant detection system, a controller for an occupant detection system and a method of detecting an occupant. The presence or absence of the occupant varies the dielectric properties of an area proximate an electrode to influence the electrical impedance of the electrode. The electrode impedance is determined by determining electrical characteristics of a filter formed by a reference impedance device and the electrode. The pole frequency and absolute attenuation of the filter are determined based on a relative ratio of the excitation signal magnitude and the electrode signal magnitude, at two distinct frequencies. A lookup table may be used to determine the pole frequency and absolute attenuation based on the relative ratio, and thereby determine an occupant presence based on the electrode impedance.

Abstract: A method for detecting an engine block heater includes block heater detection logic and a data table containing calibration thresholds. The method determines a time-series of delta (?) engine coolant temperatures (ECT), which represent the respective differences between a start-up ECT and a plurality of operating ECT values measured thereafter. The method integrates the time-series to obtain a ? ECT integral. The method also maintains an integrated engine speed parameter accumulated over the course of the detection period. Throughout the detection period, the method retrieves a threshold value from the table based on the integrated engine speed (Y-axis) versus an elapsed time (X-axis) since the detection period began. When the calculated ? ECT integral value exceeds the retrieved threshold, the method determines that the block heater was operated, which can thereafter be used to suppress sensor rationality testing or reporting of results thereof.
