    摘要： Oxides of nitrogen are adsorbed onto the surfaces of gas passages (68) in a bed (57, 100) that has relative rotation with respect to a gas inlet distributor (76, 101). The manifold has a baffle (85) or ribs (121, 122) that causes constantly flowing engine exhaust (53) to enter the gas passages over a large portion of a revolution of the adsorption bed or the distributor, and causes constantly flowing regeneration gas (54) to thereafter pass through those passages during a small portion of each revolution. The passages may be formed by planar (66a) or helical (66b) radial walls (66), a serpentine wall (70), a monolith (126), or a honeycomb (127). Either the distributor (101) or the bed (57) may be rotated to distribute the gases.

    摘要： A method for detecting a leak in a closed-volume liquid system comprises circulating a fluid through a closed-loop with a pump having a reservoir and that is driven by an electric motor. The method also comprises sensing a pressure in the closed-loop, sensing current draw by the motor and sensing fluid level in the reservoir. The method further comprises determining a presence of a leak of fluid from the closed-loop based upon two of the sensed signals using a first leak detection logic, and determining the presence of a leak of fluid from the closed-loop based upon at least one of the sensed signals using a second leak detection logic.
