    摘要： Methods and systems are provided for operating an engine having a hydrocarbon retaining system and an emission control device coupled to an engine exhaust, the engine exhaust comprising a venturi. One example method comprises, during a storing condition, routing exhaust gas through the venturi without generating a venturi action, and then to the hydrocarbon retaining system, while bypassing the emission control device, to store hydrocarbons in the hydrocarbon retaining system, and during a purging condition, routing exhaust gas through the venturi while generating venturi action, then to the emission control device, and then to the hydrocarbon retaining system, to purge stored hydrocarbons, wherein a flow of purged hydrocarbons is drawn back to the venturi via venturi action.

    摘要： Disclosed are an electrical connector and a method for providing transmit and receive electrical signal contacts to reduce or minimize total crosstalk. Such methods may be particularly suitable for connectors having larger near-end crosstalk aggressors than far-end crosstalk aggressors. The electrical signal contacts may be subdivided on a substrate, such as a midplane PCB, and through the opposing connectors, such that the transmitting contacts are all on one side of the connector and the receiving contacts are on the other side of the connector, with a buffer between them. The buffer may comprise a plurality of “dummy” or “buffer” contacts, which may be unassigned or devoid of electrical connectivity. This is one step beyond the primary assignment of contacts as single-ended or differential signal contacts. The contacts themselves may also receive a secondary assignment according to their desired transmitting, receiving, or buffering function.

    摘要： Provided is an electrical connector that may reduce crosstalk between leadframe assemblies. Such a connector may have a connector housing, a first leadframe assembly contained in the housing, and a second leadframe assembly contained in the housing adjacent to the first leadframe assembly. The first leadframe assembly may have a first differential signal pair of electrically-conductive contacts. The second leadframe assembly may have a second differential signal pair of electrically-conductive contacts. Each contact of the first and second differential signal pairs may have a respective first portion, a second portion, and a third portion. Crosstalk generated on the second differential signal pair by a signal traveling through the first portions of the contacts of the first differential signal pair may be reduced by crosstalk generated on the second differential signal pair by the signal as it travels through the second portions of the contacts of the first differential signal pair.

    摘要： A preferred embodiment of a modular electrical connector includes a plug having a printed circuit board, a contact finger positioned on a portion of the printed circuit board, and a housing for supporting and constraining the printed circuit board so that the portion of the printed circuit board extends from the housing. The printed circuit board has a flexible portion that permits the portion of the printed circuit board to translate in relation to the housing. The modular electrical connector also includes a receptacle for mating with the plug and having a first contact for electrically contacting the contact finger when the plug and the receptacle are mated, and a housing having a slot formed therein for receiving the portion of the printed circuit board when the plug and the receptacle are mated.
