air fuel rationとは 意味・読み方・使い方

Further, the air/fuel ratio of the exhaust gas present near the second air/fuel ratio sensor is estimated as the second air/fuel ration estimated value based on the average value of the air/fuel ratios of the respective cylinders.例文帳に追加

また、各気筒の空燃比の平均値に基づいて、第２の空燃比センサの近傍に存在する排気ガスの空燃比を、第２空燃比推定値として推定する。 - 特許庁

At the initial time when regeneration control of the downstream catalyst is started, the group of first cylinders and the group of second cylinders have a rich air-fuel ratio and a lean air-fuel ration, respectively, so that an air-fuel ratio flowing into the downstream catalyst does not become a theoretical air-fuel ratio.例文帳に追加

下流側触媒の再生制御開始当初は第１気筒群をリッチ空燃比、第２気筒群をリーン空燃比として下流側触媒に流入する空燃比が理論空燃比とならないように図る。 - 特許庁

A cylinder-by-cylinder air-fuel ration F/B control is executed on the basis of an air-fuel ratio measured with the A/F sensors 58a, 58b and corrected the air-fuel ratio which is an addition value with the air-fuel ratio fluctuation estimation value.例文帳に追加

そして、Ａ／Ｆセンサ５８ａ、５８ｂにより計測される空燃比と、空燃比変動推定値との加算値である補正空燃比に基づき、気筒別空燃比Ｆ／Ｂ制御を行う。 - 特許庁

When a resuming condition of fuel injection is met from a deceleration fuel-cut state, a clamp state is held until a detected air-fuel ratio of an air-fuel ratio sensor becomes below a predetermined value, and the air-fuel ration feedback control is resumed after the detected air-fuel ratio of the air-fuel ratio sensor becomes below the predetermined value.例文帳に追加

減速燃料カット状態から燃料噴射の再開条件が成立すると、空燃比センサの検出空燃比が所定値以下になるまでクランプ状態を保持させ、空燃比センサの検出空燃比が所定値以下になってから空燃比フィードバック制御を再開させる。 - 特許庁

When the response parameter P exceeds threshold by continuous n times, activation of the air fuel ration sensor is judged.例文帳に追加

そして、前記応答パラメータＰがｎ回連続して閾値を超えるようになった時点で、空燃比センサの活性を判定する。 - 特許庁

When NOx absorption amount reaches a certain value, an exhaust air-fuel ration in #1 cylinder is made rich and NOx is separated.例文帳に追加

ＮＯｘ吸収量がある値に達すると、＃１気筒の排気空燃比がリッチ化され、ＮＯｘが脱離される。 - 特許庁

To prevent occurrence of such a condition that the air-fuel ration becomes rich so as to discharge particulate components when the operating condition of an engine abruptly varies.例文帳に追加

エンジンの運転状態が急変した場合等に、空燃比がリッチになってパティキュレート成分が排出されるのを防止する。 - 特許庁

When air fuel ration is made rich, a proportional term gain GainP which is established to satisfy an inequality GainPr(Rich)<GainPl(lean) is selected (step 110, 114, 118).例文帳に追加

リッチ寄せを行う場合には、GainPr（リッチ）＜GainPl（リーン）となるように設定された比例項ゲインGainPを選択する（ステップ１１０、１１４、１１８）。 - 特許庁
