    摘要： The muffler for a motorized vehicle includes a housing with an inlet chamber and an outlet chamber, an exhaust inlet, and an exhaust outlet. The muffler includes a first channel with a first noise dampening amount that is within the housing interior, to fluidly connect the inlet chamber and the outlet chamber. The muffler includes second channel with a second noise dampening amount that is within the housing interior between the inlet chamber and the outlet chamber. The first noise dampening amount is greater than the second noise dampening amount. A valve selectively fluidly connects the inlet chamber and the outlet chamber thorough the second channel, and is configured to variably obstruct the flow of exhaust gas through the second channel. In various embodiments, the muffler has more than one inlet chamber and more than one exhaust outlet.

    摘要： Exhaust aftertreatment assemblies and methods of manufacturing and operating exhaust aftertreatment assemblies. The exhaust aftertreatment assembly includes a reductant delivery device, a reductant source fluidly coupled to the reductant delivery device, a mixing chamber positioned between the reductant delivery device and the reductant source and thereby fluidly coupling the reductant source to the reductant delivery device, and a compressed air source fluidly coupled to the mixing chamber upstream of the mixing chamber with respect to the reductant delivery device. The compressed air source provides compressed air to mix with reductant in the mixing chamber.

    摘要： In a multi-gas sensor control apparatus 1, the concentrations of ammonia, NO2, and NO contained in a gas under measurement are computed as a result of execution of gas concentration computation processing by a CPU 61 of a microcomputer 60. In the gas concentration computation processing, depending on whether or not a correction permission condition is satisfied (S200), the CPU 61 switches its operation between an operation of storing the latest corrected ammonia concentration as a value of “NH3 concentration (this time)” (S170) and an operation of storing a value of “NH3 concentration (reference)” as a value of “NH3 concentration (this time)” (S210). The multi-gas sensor control apparatus 1 can suppress a decrease in the accuracy of detection of the ammonia concentration performed through use of a multi-gas sensor 2.

    摘要： A method is disclosed for controlling a concentration of oxygen that is measured by an oxygen sensor of an after-treatment system of an internal combustion engine when a regeneration of an after-treatment device is required. The method may be a computer-implement method, An oxygen sensor target value is lowered in a stepped phase as a function of an exhaust gas flow speed as the exhaust gas passes through the after-treatment system. The oxygen sensor target value is lowered evenly as a function of the exhaust gas flow speed and by a filter phase when a measured air/fuel ratio value is less than or equal to an AFR threshold value and until the oxygen sensor target value is equal to an oxygen sensor final target value. The oxygen concentration is controlled by applying the oxygen sensor target value.
