Λ approximationとは 意味・読み方・使い方

The excess air ratio and the exhaust gas temperature determined in such a manner are substituted for the approximation formula to calculate an actual theoretical excess air ratio λp, and difference Δλ between theoretical excess air ratio λ* and the actual theoretical excess air ratio λp.例文帳に追加

こうして求められた空気過剰率および排気温度を、近似式に代入し、実理論空気過剰率λpを算出し、理論空気過剰率λ^*と実理論空気過剰率λpの差Δλを算出する。 - 特許庁

Throttle opening of the engine is determined beforehand and a map Th-λof throttle opening and excess air ratio, and a constant characteristic curve map EGT-AF-Th of exhaust gas temperature and excess air ratio are created, and an approximation formula approximating to EGT-AF-Th is defined.例文帳に追加

予め、エンジンのスロットル開度を求め、スロットル開度と空気過剰率のマップTh-λと排気温度と空気過剰率の特性曲線マップEGT-AF-Thを作成し、EGT-AF-Thに近似する近似式を求めておく。 - 特許庁
