Claims (1)
- 高地でのターボチャージャ付きエンジンの使用時におけるタービン回転数の過剰な上昇を回避するためのタービン保護装置であって、排気側から排気ガスの一部を抜き出して吸気側へ戻す再循環パイプと、該再循環パイプの途中に装備されて排気ガス流量を調整する制御バルブと、現在の高度を判定する高度判定手段と、該高度判定手段の判定に応じてタービン回転数を許容値以下に抑え得る開度で前記制御バルブを開操作する制御装置とを備え、前記高度判定手段が大気圧を検出する気圧センサで構成されていると共に、前記制御装置が大気圧と前記制御バルブの開度との二次元制御マップを組み込んでいて該二次元制御マップに照らして大気圧に対応する制御バルブの開度を決定するように構成されていることを特徴とするタービン保護装置。
