Abstract
【解決手段】吸気管9のコンプレッサハウジング15aより下流に高圧スロットル弁13を配置し、内燃機関1の停止要求が発せられた場合、まず低圧スロットル弁10を開弁させてから高圧スロットル弁13を閉弁する。
【選択図】図2
Description
内燃機関の排気通路に配置されるタービンと該内燃機関の吸気通路に配置されるコンプレッサとを有するターボチャージャと、
前記タービンより下流の排気通路内を流れる排気の一部を前記コンプレッサより上流の吸気通路内に再循環させるEGR通路と、
前記コンプレッサより下流の吸気通路に設けられ、該吸気通路を開閉自在とする第1スロットル弁と、
前記EGR通路によって再循環される排気の吸気通路への導入口より上流の吸気通路に設けられ、該吸気通路を開閉自在とする第2スロットル弁と、
前記内燃機関を停止させる時に前記第2スロットル弁が開弁された状態で前記第1スロットル弁を閉弁する制御手段と、
を備えることを特徴とする。
振動・騒音の発生を抑制することが可能になる。
aが設けられている。コンプレッサハウジング15aより上流の吸気管9には、内燃機関1で発生したブローバイガスを導入するブローバイガス管21が接続されている。
御について説明する。
低圧スロットル弁10より下流の領域は負圧になり易い傾向があり、低圧スロットル弁の開度がわずかでも閉弁方向に制御されていると、内燃機関1の停止要求が発せられた時点での内燃機関1の運転状態や、低圧EGRガス或いは吸気の流れの状態などによっては、吸気管9の低圧スロットル弁10より下流の領域がすぐに負圧状態になってしまう可能性があるからである。
