An exhaust treatment apparatus (ATA) is provided for reducing one or more components of the airstream directed through the ATA. The ATA includes an airstream inlet, an airstream outlet, and an airstream path directed through the ATA from the airstream inlet to the airstream outlet, and at least one corona/NTP generating region for altering a composition of an airstream passing through the ATA. The ATA includes an outer enclosure forming one electrode surface and a second electrode surface positioned within and electrically insulated from the outer enclosure electrode surface, where an area between the outer enclosure electrode surface and the second electrode surface forms at least a part of the airstream path directed through the ATA. The second electrode surface comprises a series of ridges positioned along the airstream path and directed towards the outer enclosure that encourage corona generation. A method is provided for using the ATA for treating an airstream, including an exhaust airstream from a combustion engine, as well as an exhaust airstream from a compression-ignition (diesel) engine.

A method includes determining, at a controller having one or more processors, whether an ambient temperature is less than a predetermined temperature indicative of frozen reductant in an exhaust system of an engine. The method includes determining an injector thaw period for a reductant injector in the exhaust system when the ambient temperature is less than the predetermined temperature. The method includes determining a tank thaw period for a reductant tank associated with the exhaust system, the reductant tank being configured to supply reductant to the reductant injector. The method also includes controlling (i) a heater to heat the reductant tank for the tank thaw period and (ii) a current provided to the reductant injector for the injector thaw period, such that the tank thaw period and the injector thaw period end at a same time.

In one embodiment, a method for manufacturing a fluid storage tank assembly for an off-road vehicle includes disposing a support ring within a cavity of a rotational mold, in which the cavity is shaped to form a fill spout of the fluid storage tank assembly. The method further includes flowing a liquid polymeric material within the rotational mold such that the liquid polymeric material enters the cavity, directly contacts the support ring, and bonds to the support ring as the liquid polymeric material hardens.
摘要:
A method and system for treating emissions includes charging particles in an exhaust stream, producing one or more radicals, and oxidizing at least a portion of the charged particles with at least a portion of the produced radicals. At least a portion of the charged particles in the exhaust stream are then attracted on at least one attraction surface which is one of oppositely charged from the charged particles and grounded. The attracted particles are oxidized with another portion of the one or more produced radicals to self regenerate the at least one attraction surface. Downstream from where the attracted particles are oxidized, at least a portion of one or more first compounds in the exhaust stream are converted to one or more second compounds downstream from the attracting. Additionally, at least a portion of any remaining charged particles are oxidized into one or more gases.

Aggregation of particulate matter is facilitated. Provision is made for an electrode that is arranged in an exhaust passage of an internal combustion engine with a voltage to be applied thereto being able to be changed, a detection device that detects an electric current passing through the electrode, a determination device that determines whether a pulse current has been generated in the electric current detected by the detection device, and a control device that reduces the voltage to be applied more than that at this time in cases where a determination has been made by the determination device that a pulse current has been generated.
摘要:
A device and a method for producing electrical energy from an exhaust gas of an internal combustion engine include a generator with an exhaust gas inlet, an exhaust gas outlet and a heat exchange portion therebetween. The heat exchange portion includes a plurality of flow paths for the exhaust gas. The flow paths are at least partially surrounded by thermoelectric elements which are in thermally conductive communication with a cooling device on a side facing away from the flow path. A motor vehicle having the device or carrying out the method, is also provided.

A concentration of HC in an exhaust gas is estimated with a high degree of accuracy by making use of a particulate matter processing apparatus (1). In the particulate matter processing apparatus (1) in which a processing part (3) with an electrode (5) installed therein is arranged in an exhaust passage (2) of an internal combustion engine, wherein particulate matter is caused to aggregate by generating a potential difference between the electrode (5) and the processing part (3), provision is made for a power supply (6) that is connected to the electrode (5) and applies a voltage thereto, an insulation part (4) that insulates electricity between the processing part (3) and the exhaust passage (2), and a ground part (53) that grounds the processing part (3), a detection device (9) that detects an electric current in the ground part (53), and an estimation device (7) that estimates a concentration of HC in an exhaust gas based on the electric current detected by the detection device (9) at the time when the voltage is applied to the electrode (5) by means of the power supply (6).
