Abstract (en)

[origin: WO2008143412A1] 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.
