摘要： A method of making a titanium dioxide nanowire array includes contacting a substrate with a solvent comprising a titanium (III) precursor, an acid, and an oxidant while microwave heating the solvent, thereby forming a hydrogen titanate H2Ti2O5.H2O nanowire array. The hydrogen titanate nanowire array is annealed to form a titanium dioxide nanowire array. The substrate is seeded with titanium dioxide before starting the hydrothermal synthesis of the hydrogen titanate nanowire array. The titanium dioxide nanowire array is loaded with a platinum group metal to form an exhaust gas catalyst. The titanium dioxide nanowire array can be used to catalyze oxidation of combustion exhaust.

摘要： Methods and systems are provided for a turbocharger. In one example, a method may include bypassing exhaust gases flowing to the turbocharger in response to a catalyst temperature being less than a threshold temperature. The bypassing includes opening a bypass valve and adjusting a position of one or more turbine nozzle vanes.

摘要： A system includes an aftertreatment system coupled to an engine, a heater, at least one sensor configured to determine an exhaust gas temperature, and a processing circuit. The processing circuit is structured to determine whether the exhaust gas temperature is at or below a predefined threshold temperature; provide a first command to control the heater in response to the exhaust gas temperature being at or below the predefined threshold temperature; selectively provide a second command to increase the exhaust gas temperature; and coordinate the first and second commands, where the first command is provided followed by the second command only if the predefined threshold temperature is not attained by the first command.

摘要： An aftertreatment system includes a selective catalytic reduction (SCR) system, a heater, and a controller that determines a rise in temperature of exhaust gas at an outlet of the heater for a plurality of power levels, predicts a first temperature of the exhaust gas at the outlet of the heater based on the rise in temperature, predicts a second temperature of the exhaust gas at a location of the SCR system based on the first temperature, compares the second temperature for each of the plurality of power levels with a target temperature of the exhaust gas at the inlet of the SCR system, selects one of the plurality of power levels based on the comparison, and adjusts operation of the heater based on the selected one of the plurality of power levels to achieve the target temperature of the exhaust gas at the inlet of the SCR system.

摘要： An exhaust gas/reactant mixing assembly for an exhaust gas system of an internal combustion engine includes a mixing channel defining a longitudinal axis and extending in the direction thereof. A reactant delivery unit delivers reactant (R) into the mixing channel and an exhaust gas supply channel is arranged upstream of the mixing channel. The exhaust gas supply channel opens into the mixing channel at an opening channel region, wherein the opening channel region has at least two opening channel portions opening into the mixing channel.

摘要： A honeycomb structure according to at least one embodiment of the present invention includes: a honeycomb structure portion having: an outer peripheral wall; and a partition wall arranged inside the outer peripheral wall to define a plurality of cells each extending from a first end surface of the honeycomb structure portion to a second end surface thereof to form a flow path; and a pair of electrode portions arranged on an outer peripheral surface of the outer peripheral wall of the honeycomb structure portion. The electrode portions are each a porous body in which particles of silicon carbide are bound by a binding material, the silicon carbide contains α-type silicon carbide and β-type silicon carbide, and the silicon carbide has a D50 in a volume-based cumulative particle size distribution of 25 μm or less.
