Abstract: An exhaust gas treatment system for an internal combustion engine is provided and includes an exhaust gas conduit, a hydrocarbon supply, a particulate filter (“PF”), at least one sensor, a first temperature sensor, a second temperature sensor, and a control module. The PF is in fluid communication with the exhaust gas conduit and has a filter structure for removal of particulates in the exhaust gas. The filter structure has an innermost region and an outermost region. The PF is selectively regenerated during operation of the internal combustion engine. The PF has a stratified temperature structure that causes the particulates trapped at the innermost region of the PF burn off before the particulates trapped in the outermost region of the PF during regeneration. The control module has a memory with an infinite stage temperature control curve stored thereon.

Abstract: A change-gear transmission having an input shaft, a main shaft having at least one main shaft gear, a plurality of countershafts spanning between the input shaft and main shaft gear, and gear synchronizers between selectable gears. The bore of main shaft gears have a minimal radial clearance fit with its mating parts to prevent gear synchronizer wear, while the meshing between the input shaft gears and countershaft gears is equally distributed using a means to equalize the torque transfer between countershafts. The countershafts are rotatably supported and displace axially between bearing or bushing supports, while the meshed gears comprise a helical gear tooth arrangement to create axial load on the countershaft if excessive and uneven load is sensed in one countershaft over another. This presents a new and unique countershaft meshing design that allows multiple countershafts to achieve equal load sharing while permitting gear synchronizers use on the main shaft.
