Abstract: A hydrocarbon trap catalyst and method of forming the same are disclosed. The method may include introducing copper into a zeolite at 10% to 75% of an ion-exchange level of the zeolite, introducing at least one of nickel and manganese into a zeolite at 50% to 100% total of an ion-exchange level of the zeolite, and applying a three-way catalyst layer. The copper and nickel and/or manganese may be introduced into a single zeolite or the copper may be introduced into a first zeolite layer and the nickel and/or manganese may be introduced into a second zeolite layer. If copper and another metal are introduced into the same zeolite, copper may be introduced first. The disclosed trap catalyst may increase the release temperature of hydrocarbons such as ethanol, propylene and toluene, and thus reduce vehicle cold start tailpipe emissions.

Abstract: A motor-vehicle engine system comprises a first DOC configured to receive exhaust from an engine and an SCR device coupled downstream of the first DOC in a flow direction of the exhaust. The system further comprises a second DOC coupled downstream of the SCR device. The system takes advantage of hydrocarbon sorption in the SCR catalyst that is a function of temperature to enable reduced hydrocarbon emissions via oxidation at the second DOC.

Abstract: Methods and systems for controlling and/or diagnosing an emission control system of a vehicle having a first SCR region upstream of a second SCR region are provided herein. One exemplary method includes, indicating degradation based on a first SCR region performance during a first condition; and indicating degradation based on a second SCR region performance during a second condition, the first condition different than the second condition. In this way, different levels of degradation among different SCR regions may be used to indicate emissions levels have increased above a threshold value, for example.

Abstract: A reverse flow hydrocarbon trap is provided that improves the conversion of hydrocarbons present in the exhaust gases of a vehicle to more environmentally benign compounds during cold engine starts. The trap includes a substrate having at least one exhaust gas passage therethrough, with the walls of the exhaust gas passage including a hydrocarbon trapping material and an oxidative catalyst. The substrate includes an inlet for hot exhaust gas from a vehicle engine and an outlet for the exhaust gas and further includes an inlet channel, an outlet channel, and an intermediate channel through which exhaust gas flows. The intermediate channel is oriented such that the flow of exhaust gas through the exhaust gas passage is reversed from the direction of flow in the inlet and outlet channels to improve the performance of the hydrocarbon trap.

Abstract: An electrical connector includes an insulative housing defining a rear wall and a mating cavity running through a front end of the insulative housing from the rear wall, the rear wall defines an inner surface facing the mating cavity. A plurality of conductive terminals are fixed in the insulative housing and include a plurality of grounding terminals, each conductive terminal defines a body portion and a first contacting arm extending into the mating cavity. And a grounding plate is disposed in the rear wall and defines a plurality of contacting portions running through the inner surface and extending into the mating cavity and a plurality of connecting portions connecting to the respective body portions of the grounding terminals.

Abstract: An electrical connector comprises an insulative housing, a plurality of conductive terminals secured in the insulative housing, a metal shell shielding around the insulative housing and a magnetic element retained in the metal shell. The metal shell forms an accommodating room for receiving the magnetic element. The magnetic element has an outer surface and a recess defined on the outer surface. The metal shell has a retaining arm corresponding to the recess. The design of the recess and the retaining arm make a better retaining effectivity for the electrical connector.

Abstract: A material distributing boom of a material distributing apparatus comprises at least two boom sections. A material distributing control method comprises: first, controlling the first boom section to move to a vertical state, and keeping the first boom section in the vertical state; second, controlling other boom sections to move to accomplish material distributing work. A material distributing apparatus implements the material distributing control method. On the premise of ensuring maximum material distributing height, the material distributing control method provided achieves reduced supporting spans of the legs of the material distributing apparatus in material distributing work and provides possibility for reducing the strength of the legs by sacrificing the material distributing radius to some degree innovatively.
