Description
熱交換室内の圧力を測定するステップ、
熱交換室内の圧力の曲線上の特性点を基準として定められた所定の時点に、熱交換室内の圧力を測定することにより、時間の関数として雰囲気圧を求めるステップ。
ただし、このとき雰囲気圧は測定された熱交換室内の圧力に等しくなっている。
図2〜4は、異なる状況における図1のバタフライ弁の位置と図1の熱交換室16及び給気マニホルド内の圧力とを同じグラフに示した図である。
AMP=MAP_UP+ΔP
であることが観察される。ΔPの値は特にエンジン回転数の関数として変化することが知られている。純粋に大きさのオーダーを示す目的で、例えば、アイドリング状態ではΔP≒−4mbarであり、6000r.p.mの近傍ではΔP≒−14mbarであることが分かる。
Claims (8)
