Abstract
【解決手段】燃焼機関の排気ガスを再循環させる構造は、燃焼機関へ排気ガスを戻す戻りライン11と、燃焼機関へ導かれる前に排気ガスを冷却するEGRクーラー装置14,15と、EGRクーラー装置内に生じる凝縮液を集めるための容器装置15cと、容器装置15cをEGRクーラー装置の排気ガス流路部に連結するライン24と、容器装置15cから凝縮液をEGRクーラー装置の排気ガス流路部へ導く駆動手段とを含む。駆動手段は、容器装置15cの底部15dにおける凝縮液レベルを検出するセンサー27と、センサー27からの情報に基づいて駆動を制御されるポンプ25とを含む。
【選択図】図2
Description
第2のEGRクーラー15および過給空気クーラー9がこのように位置決めされることにより、圧縮空気および再循環排気ガスは周囲温度に近い温度にまで冷却されることができる。空気および排気ガスは小さな比容積を占めるように冷却され、これにより大量の空気および再循環排気ガスが燃焼機関のシリンダに供給できるようになる。
