摘要： The invention relates to a device (1) for providing a gaseous mixture comprising at least one of the following substances: a) at least one reducing agent and, b) at least one reducing agent precursor. A reservoir (20) is configured for the aqueous solution (45) comprising at least one reducing agent precursor. Said aqueous solution (45) can be transported from said reservoir by transporting means (19) in at least on supply line (2) equipped with output openings (3). The invention is characterised in that said device comprises means (4) for heating the supply line (2), said means being able to heat at least one supply line (2) above a critical temperature that is greater than the boiling point of water. Said inventive device (1) and the inventive method allow the aqueous solution comprising urea to be completely evaporated in an advantageous manner and subsequently hydrolysed to a mixture comprising ammonia. Said mixture is added in an advantageous manner to a SCR catalyst (18) as a reducing agent. Evaporation is carried out outside the waste gas system enabling visibly smaller hydrolysis catalysts (17) to be formed such that the inventive device is more compact and economical compared to conventional devices used for providing a reducing agent for selective catalytic reduction of nitrogen.

摘要： A freeze-resistant metering valve is provided that comprises a magnetic part and a hydraulic part. The magnetic part has an armature biased by a spring. The hydraulic part has an annular space for receiving and conveying a liquid as well as a tappet facing a valve seat. The valve seat comprises a nozzle opening on the side facing away from the tappet. In a currentless state, the tappet blocks the annular space in the direction of an opening (nozzle opening) until a freezing pressure exerted onto the armature generates a sufficient force by virtue of the solidifying liquid. This force is used to counteract the spring force until a freeze expansion space is created by way of a relieving motion.

摘要： PURPOSE: An exhaust emission control system of internal combustion engine is provided to control a function of a NOx catalyst by injection-supplying a reducer directly into an exhaust system of the internal combustion engine, and stably supply a desired quantity of reducer at a desired timing without being influenced by the heat derived from the exhaust gas. CONSTITUTION: A fuel adding nozzle is embedded including its front end member(17c) into an internal wall of an exhaust port(40a) formed within a cylinder head(100a). An injection passageway(101c) guides, into the exhaust port, the fuel jetted out of the front end member of the fuel adding nozzle. A wall(102) provided between the front end member and the exhaust port decreases a heat receiving quantity of the fuel adding nozzle. A water jacket(110) is proximal to an outer edge of a nozzle seat(103), thereby efficiently transferring the heat contained in a gasket(17d) to cooling water in the water jacket.

摘要： 본발명에따른차량배기시스템은, 개구를구비하는엔진배기가스통로를획정하는배기부품을포함한다. 정량주입기는, 정량주입기축을획정하고, 환원제를상기개구를통하여엔진배기가스통로내로분사하도록구성되어있는정량주입기선단까지연장된다. 원뿔형부는, 상기정량주입기선단의주위에서상기배기부품내에환형갭이형성되도록, 상기개구에인접하게배치되는기단부를구비한다. 배기가스는, 상기정량주입기축을가로지르는방향으로상기환형갭을통과하여상기원뿔형부의기단부를향하게된다. 이러한구성은, 혼합물이하류측배기부품에도입되기전에, 환원제가엔진배기가스와완전히혼합될수 있게하는동시에, 침착물의형성을감소시킨다.
