Abstract: An engine exhaust treatment and fuel efficiency improvement system includes a NOx module that determines a quantity of NOx emitted from an engine. A selective catalytic reduction (SCR) efficiency module determines a SCR efficiency to reduce the determined NOx quantity below a predetermined threshold. A reagent dosing module determines a quantity of reagent required to reduce the NOx quantity below the predetermined threshold. An injection optimization module determines whether an increase in system operating efficiency may be obtained by changing an injected reagent quantity and an engine operating parameter in cooperation with each other while maintaining the NOx quantity below the threshold, the system being operable to change the reagent injection quantity and engine operating parameter to increase system efficiency.

Abstract: A method of determining an optimized position for a burner in an exhaust aftertreatment system includes estimating temperature distributions across faces of exhaust treatment devices positioned within parallel paths based on an initial burner position upstream of the parallel paths. A temperature distribution across the faces of the exhaust treatment device is again estimated based on a changed burner position. A difference between the estimates is determined. The changing, estimating and determining steps are repeated to correlate the burner position with a temperature variance across the faces. An optimized burner position is determined based on minimizing the temperature variance across the faces of the exhaust treatment devices.

Abstract: A shock absorber includes a piston assembly which includes separate flow paths. Each flow path is controlled by a valve assembly and each flow path is in parallel with the other two flow paths. One flow path will generate firm damping characteristics. A second flow path opens depending on either the frequency of the shock absorber movement or the amount of movement or stroke of the shock absorber. The third flow path includes an on/off control valve and generates a soft damping characteristic when the control valve is activated. The soft damping characteristic can be generated by a tunable bleed restriction or by a passive valve assembly.
