Description
Claims (2)
- 圧力容器から送出されたガス燃料を減圧調整するレギュレータと、減圧したガス燃料を吸気通路に送出するミキサーを備えており、前記レギュレータと前記吸気通路側が負圧配管で接続されて吸気管負圧を前記レギュレータ内に導入する負圧配管が形成されており、
EGRクーラーおよびEGRバルブを含む排気再循環装置(EGR装置)から送出された排気を前記ミキサーに導入してガス燃料に混合する方式のエンジンシステムに適用されるエンジンのガス燃料供給装置において、
前記吸気通路から侵入した水分を除去する水分除去手段が、エンジン吸気管と前記負圧配管との接続部分に配設されていることを特徴とするガス燃料供給装置。 - 前記水分除去手段は、両端側に接続口を有して気密に形成した筒状のフィルタケース内に、中空部の基端側が開口して前記接続口の一つに連通し前記中空部の先端側を閉塞してなる中空フィルタが、その外周面と前記フィルタケースの内周面との間に隙間が形成されるように挿設されており、一端側の前記接続口から導入した気体が前記中空部と前記隙間との間でフィルタを通過しながら他端側の前記接続口から送出されることで、導入した気体に含まれる水分が吸着・除去されるものとした気体用フィルタ装置であることを特徴とする請求項1記載のガス燃料供給装置。
