摘要： The present invention relates to an injector for an exhaust purifying device of a diesel vehicle. The object of the invention is to provide an injector for an exhaust gas purifying device, which can control the jet amount of diesel fuel more precisely with minimizing the loss of performances owing to deterioration of the injector. According to the present invention, an injector is cooled by utilizing the flow of diesel fuel, to provide efficient cooling of the injector. Accordingly, the influence of lowered performances is minimized, and the problem of lowered jet efficiency of a nozzle can be fundamentally eliminated. In addition according to the present invention, the jet amount of diesel fuel can be more precisely controlled. Therefore, the required amount of diesel fuel jet in order to raise the gas temperature to a predetermined temperature can be reduced, and overall fuel efficiency of the vehicle can be thus improved.

摘要： The present invention relates to an exhaust gas purifying device for a diesel engine, which efficiently purifies nitrogen oxides ("NOx") and particulate matter in an internal combustion engine. More specifically, the present invention provides an exhaust gas purifying device having catalyst section for selective reduction of nitrogen oxides (SCR), equipped with a diesel injection unit (or called as a reductant injection unit) which can inject light oil (if necessary, hydrocarbon such as gasoline may be used) at the fore-end of the catalyst section for selective reduction of nitrogen oxides, wherein light oil as reductant flowing from a reductant injection unit into the exhaust gas purifying device via injection is treated by a plasma modifier, to be subjected to partial oxidation, so that modified reductant is injected to the fore-end of the SCR in the exhaust gas purifying device.
