摘要： A nozzle device includes: a charging nozzle configured to supply a charging fluid and provided to be connected to a receptacle provided in a subject; a cover member to surround the charging nozzle and the receptacle; and a fluid supply unit to supply an interior of the cover member with an anti-freezing fluid for inhibiting freezing between the charging nozzle and the receptacle, thereby obtaining an advantageous effect of preventing freezing of the receptacle and improving safety and reliability. In addition, the nozzle device may include a hydrophobic coating layer for inhibiting freezing.

摘要： A lean NOx trap (LNT) catalyst includes a plurality of carriers connected to each other in series, wherein each of the carriers is embedded with at least one of a first wash coat containing magnesium (Mg)-substituted alumina, ceria (CeO2), barium (Ba), and a precious metal, a second wash coat containing magnesium (Mg)-substituted alumina, ceria (CeO2), barium (Ba), a third wash coat containing magnesium (Mg)-substituted alumina, ceria (CeO2), and a fourth wash coat containing magnesium (Mg)-substituted alumina, ceria (CeO2), and a higher content of a precious metal than the first wash coat, a ratio of the magnesium-substituted alumina to ceria (CeO2) being lower than that of the third wash coat, wherein the third and first wash coats are disposed in a foremost carrier through which exhaust gas passes sequentially from a front portion of the foremost carrier.
