ENGINE SYSTEM WITH CONDENSED WATER TREATMENT FUNCTION

PROBLEM TO BE SOLVED: To provide an engine system with a condensed water treatment function capable of positively preventing condensed water generated through cooling action of an inter-cooler from flowing into an engine and additionally preventing fuel mixture gas from being discharged outside.SOLUTION: An engine system with a condensed water treatment function is constituted in such a way that condensed water W generated at an inter-cooler 3 flows into a fuel mixture gas flowing part 7. The fuel mixture gas flowing part 7 is provided with a condensed water storing part 7a where the condensed water W is stored. There is arranged a condensed water storing tank 9 enabling the condensed water W to be stored at a lower side in a vertical direction than that of the fuel mixture gas flowing part 7. There are provided a condensed water discharging pipe 10 for feeding the condensed water W from the fuel mixture gas flowing part 7 into the condensed water storing tank 9 and a feeding pipe side mixture gas return pipe 18 for connecting the condensed water storing tank 9 with an air feeding pipe 20 for feeding suction air A into a mixing unit 1, and the feeding pipe side mixture gas return pipe 18 is provided with a flame arrester 16 and a throttle valve 17.SELECTED DRAWING: Figure 4 【課題】インタークーラの冷却により発生した凝縮水がエンジンに流入することを的確に回避し、しかも、燃料混合気が外部に排出されることを回避できる凝縮水処理機能付きエンジンシステムを提供する。【解決手段】凝縮水処理機能付きエンジンシステムは、インタークーラ３で発生した凝縮水Ｗが燃料混合気通流部７に流入するように構成され、燃料混合気通流部７に凝縮水Ｗが溜まる凝縮水溜部７ａが設けられ、燃料混合気通流部７よりも鉛直方向において下方に凝縮水Ｗを貯留可能な凝縮水貯留槽９が配設され、凝縮水Ｗを燃料混合気通流部７から凝縮水貯留槽９に流入させる凝縮水排出管１０と、凝縮水貯留槽９と吸入空気Ａを混合器１に導入する空気導入管２０とを接続する導入管側混合気戻り配管１８とが設けられ、導入管側混合気戻り配管１８にフレームアレスタ１６及び絞り弁１７が設けられている。【選択図】図４
