Abstract: An exhaust system that processes exhaust generated by an engine is provided. The system generally includes a particulate filter (PF) that filters particulates from the exhaust wherein an upstream end of the PF receives exhaust from the engine and wherein an upstream surface of the particulate filter includes machined grooves. A grid of electrically resistive material is inserted into the machined grooves of the exterior upstream surface of the PF and selectively heats exhaust passing through the grid to initiate combustion of particulates within the PF.

Abstract: A system includes a particulate matter (PM) filter that includes an upstream end for receiving exhaust gas and a downstream end. A zoned heater is arranged spaced from the upstream end and comprises N zones, where N is an integer greater than one, wherein each of the N zones comprises M sub-zones, where M is an integer greater than or equal to one, and wherein the N zones and the M sub-zones are arranged in P layers, where P is an integer greater than one. A control module selectively activates at least a selected one of the N zones to initiate regeneration in downstream portions of the PM filter from the one of the N zones and deactivates non-selected ones of the N zones.

Abstract: A diesel particulate filter assembly includes a diesel particulate filter (DPF) and an electric heater that is integrally formed at an upstream end of the DPF. The electric heater includes a heating substrate and a resistive heating element. The heating substrate includes a central region and a boundary region around the central region. The resistive heating element includes a plurality of conductive portions. Adjacent ones of the conductive portions in the central region form a first spacing. Adjacent ones of the conductive portions in the boundary region form a second spacing. The second spacing is smaller than the first spacing.

Abstract: An assembly tool for installing a clutch pressure plate and clutch housing of a manual clutch on the flywheel of an engine includes a bell shaped housing which receives and pivotally supports a plurality of fingers having outwardly directed claws. A coaxial cylindrical portion of the bell shaped housing includes male threads which receive a complementarily threaded collar which may be rotated to engage, radially extend and retract the fingers. Internal threads in the cylindrical portion of the housing receive a complementarily threaded portion of a push rod. The push rod includes a thrust bearing at an end that engages the fingers of the pressure plate and may be rotated to engage, retract and extend the pressure plate. A method of clutch housing installation utilizing the tool is also disclosed.
