| description | To provide a holding structure for an addition valve capable of preventing accumulation of deposit at a spray passage outlet.SOLUTION: A holding structure for an addition valve includes: an addition valve 20 adding an additive to exhaust gas of an internal combustion engine; a holder 10 holding the addition valve 20; an exhaust manifold 30; and a gasket 40 sandwiched between the holder 10 and the exhaust manifold 30. An exhaust passage 31 is provided in the exhaust manifold 30. A spray passage 11 extending from a tip 21 of the addition valve 20 to the exhaust passage 31 is provided in the holder 10. The additive is sprayed from the tip 21 of the addition valve 20 into the spray passage 31. A hole 40h allowing the spray to reach the exhaust passage 31 is provided to continue to an outlet 13 of the spray passage 11. A coating 41 is provided on the surface of the gasket 40 around the hole 40h to expose to the spray supplied from the spray passage 11, as a layer for preventing deposit.SELECTED DRAWING: Figure 2
【課題】噴霧通路出口においてデポジットの堆積を防止することが可能な添加弁の保持構造を提供する。【解決手段】内燃機関の排気ガスに添加剤を添加する添加弁２０と、添加弁２０を保持するホルダ１０と、排気マニホールド３０と、ホルダ１０と排気マニホールド３０とに挟まれたガスケット４０とを備え、排気マニホールド３０には排気通路３１が設けられており、添加弁２０の先端２１から排気通路３１まで延びる噴霧通路１１がホルダ１０に設けられており添加弁２０の先端２１から噴霧通路３１内に添加剤が噴霧され、噴霧が排気通路３１に到達することを可能にする孔４０ｈが噴霧通路１１の出口１３に連なるように設けられ、孔４０ｈの周辺に噴霧通路１１から供給される噴霧に露出するようにガスケット４０表面にデポジットを防止する層としてのコーティング４１が設けられている。【選択図】図２ |
