Abstract: An exhaust after-treatment system for treating an exhaust produced by an engine. The exhaust after-treatment system includes an exhaust passage, at least one catalytic exhaust after-treatment component in communication with the exhaust passage for treating the exhaust, and a water-removal device in communication with the exhaust passage that receives a portion of the exhaust therein at a location positioned upstream from the catalytic exhaust after-treatment component. The water-removal device is defined by a housing that includes a water-removal membrane that separates water from the portion of the exhaust to provide a permeate that is enriched with water, and to produce a retentate that is water depleted that facilitates the treating of the exhaust by the catalytic exhaust after-treatment component.

Abstract: The present disclosure provides a method of producing an insulation preform having graded porosity for an exhaust treatment component of a vehicle. The method includes obtaining a first granular insulating material having a first diameter, a second granular insulating material having a second diameter less than the first diameter, an inorganic binder, and water. The method further includes producing a slurry comprising the first granular insulating material, the second granular insulating material, the inorganic binder, and water. The slurry is introduced into a mold having at least one surface adapted for vacuum extraction. A liquid phase of the slurry is evacuated from the mold using vacuum extraction to produce a moist preform. The moist preform has graded porosity such that a greater concentration of the second insulation material is adjacent to the at least one surface than the first insulating material. The moist preform is heated to produce the insulation preform.

Abstract: A water neutralization system that includes a first source of water that is acidic and a second source of water that is basic. A storage reservoir communicates with each of the first source and the second source, and includes a pH sensor that is configured to transmit a signal indicative of a pH of the water stored in the storage reservoir. At least one valve controls fluid communication between the storage reservoir and at least one of the first source and the second source, and a controller communicates with each of the pH sensor and the valve. Based on the signal indicative of the pH of the water stored in the storage reservoir, the controller instructs the valve to adjust an amount of water received from at least one of the first source and the second source to neutralize a pH of the water stored in the storage reservoir.

Abstract: An exhaust after-treatment system for treating an exhaust produced by an engine. The exhaust after-treatment system includes an exhaust passage, a catalytic exhaust after-treatment component in communication with the exhaust passage for treating the exhaust, and a metal hydride module in communication with the exhaust passage that receives a portion of the exhaust therein at a location positioned upstream from the catalytic exhaust after-treatment component. The portion of the exhaust that enters the metal hydride module reacts with a metal hydride contained in the metal hydride module to produce hydrogen gas that facilitates the treating of the exhaust by the catalytic exhaust after-treatment component.
