An exhaust gas cleaning component, having a housing with an inflow port and an outflow port, a first honeycomb structure in the housing with a casing, the casing having an outer surface over which exhaust gas can flow, and also having an applicator device by which an exhaust gas cleaning additive can be applied to the outer surface of the casing.

A cleaning system for removal of contaminants from a surface of a vehicle component exposed to a gas or fluid flow, the cleaning system comprising: an excitation device adapted to be attached to the vehicle component in the vicinity of the surface exposed to contaminants, wherein the excitation device is configured to cause the surface to mechanically vibrate by transferring a vibrational excitation to the surface; wherein the frequency of the vibrational excitation is controllable to be based on the configuration of the vehicle component as well as other modelled/measured parameters.

A vehicle includes an exhaust aftertreatment system for use with an automotive internal combustion engine. The aftertreatment system includes one or more aftertreatment devices for removing or reducing effluents from exhaust gases produced by the combustion engine. The aftertreatment devices includes a selective catalytic reduction unit that can be heated by a power source. An electrical connection system is configured to interconnect the power source and one or more electrical components to transfer and deliver electrical power to the one or more electrical components.

The presently claimed invention relates an automotive catalyst system which can be used to selectively reduce carbon monoxide. The system comprises a first close coupled three-way conversion catalytic article in fluid communication with an engine exhaust outlet, a catalytic article located downstream of and in fluid communication with the first close coupled three-way conversion catalytic article, a tail-pipe catalytic article arranged downstream in fluid communication and 1.0 to 10 feet away from the catalytic article at a position selected from before or behind a resonator, before or after a muffler, between the resonator and the muffler, inside the muffler, inside the resonator, and at a tail pipe end.

An on-board vehicle reservoir containing an ammonia/organic solvent solution may be associated with a phase separator configured to isolate ammonia from the solution. The ammonia may be introduced into an exhaust gas stream of an internal combustion engine to function as a catalytic reductant. Ammonia may be employed to generate hydrogen via catalytic decomposition of ammonia, and the hydrogen may be introduced into an exhaust gas stream to aid catalytic reactions such as catalytic oxidation of carbon monoxide (CO) and/or hydrocarbon (HC) and/or reduction of nitrogen oxides (NO); for instance during a cold-start period.

A controller is configured to control a vehicle that includes an internal combustion engine and an automatic transmission. The controller is configured to execute a shifting process that switches a gear ratio of the automatic transmission and a lean operation process that operates the internal combustion engine with an air-fuel ratio of the air-fuel mixture in a cylinder leaner than a stoichiometric air-fuel ratio. The controller is further configured to, when executing the shifting process during execution of the lean operation process, set an air-fuel ratio in a case in which the shifting process is being executed to a value closer to the stoichiometric air-fuel ratio than an air-fuel ratio in a case in which the shifting process is not being executed.

An electrochemical reactor arranged in an exhaust passage of an internal combustion engine has a honeycomb member wherein a plurality of cells are formed. The honeycomb comprising an upstream and a downstream side partial honeycombs. The upstream side has a plurality of first and second cells arranged to at least partially adjoin the first cells through partition wall base members including an ion conductive solid electrolyte. The downstream side has a plurality of third and fourth cells arranged to at least partially adjoin the third cells through partition wall base members including an ion conductive solid electrolyte. The first and fourth cells have cathode layers, and second and third cells have anode layers. The electrochemical reactor is configured so all of the exhaust gas flowing through the first cells flows into the third cells and all of the exhaust gas flowing through the second cells flows into the fourth cells.
