Abstract: A system for treating the exhaust output by an internal combustion engine includes a regeneration positioned upstream from a diesel particulate filter. The regeneration unit combusts a fuel to heat the exhaust entering the diesel particulate filter. An air pump supplies a secondary source of compressed air to the regeneration unit and is adapted to be driven by the internal combustion engine. A speed sensor is coupled to the air pump and operable to output a signal indicative of a rotational speed of an air pump component. A controller receives the speed sensor signal and determines an operating speed of the internal combustion engine based on the speed sensor signal. The controller controls the regeneration unit based on the engine operating speed.

Abstract: An exhaust after-treatment system including an exhaust passage having at least a first portion and a second portion. An exhaust treatment component may be positioned within the exhaust passage between the first and second portions, and an insulating blanket insulates each of the first portion, second portion, and the exhaust treatment component. Temperature sensors may be positioned at the first portion, the second portion, the exhaust treatment component, wherein each sensor monitors the temperature at its location. A controller may have access to temperature data associated with an insulated exhaust after-treatment system, and the controller compares the monitored temperatures to the temperature data to determine whether a difference exceeding a predetermined threshold exists. If the difference exceeds a predetermined threshold, the controller outputs an error signal identifying particular portions of the exhaust system that are no longer insulated.
