Problems solved by technology

Therefore, the layout becomes complicated and the cost increases
[0007] In addition, when the strong alkaline urea solution is splashed back into the inlet by the pressure of the urea solution tank, the odor flows into the interior of the vehicle, causing discomfort to passengers

Abstract

The invention discloses a urea solution filler neck device which comprises: a cover body mounted on a floor of a vehicle body to correspond to a urea solution tank, the cover body has a through hole,afiller pipe body disposed at the bottom of the cover body and installed On the urea solution tank,an opening and closing cover, which is installed at the top of the through hole at the top of the filling pipe body and selectively opens and closes the through hole and the filling pipe body,and a sealing member, which is mounted on the filler pipe body within a space formed by the cover body and the filling pipe body, and a urea solution leaking from the urea solution tank is prevented from flowing into the interior of the vehicle.

Description

technical field [0001] The present invention relates to a urea solution filling pipe device, in particular to such a urea solution filling pipe device installed on the floor of a vehicle body to inject urea solution into a urea solution tank. Background technique [0002] Environmentally friendly vehicles are developing globally, and vehicle emission standards in various countries are gradually tightening. In addition, automakers have developed environmentally friendly diesel vehicles through carbon dioxide control. [0003] The core of diesel vehicle emission standards are nitrogen oxides and particulate matter. Among the reduction technologies of nitrogen oxides and particulate matter, LNT and UREA-SCR have attracted public attention. In particular, UREA-SCR is useful in reducing nitrogen oxides exhausted from diesel engines of large vehicles. [0004] In UREA-SCR, a harmless urea solution is injected into the exhaust system and the injected urea solution is converted to...
