Calculated Ignition Indexとは 意味・読み方・使い方

Cooling loss Qw is calculated from the polytropic index m and the specific heat ratio κ, and an ignition timing is corrected in accordance with the cooling loss Qw.例文帳に追加

そして、ポリトロープ指数ｍ及び比熱比κから冷却損失Ｑｗを算出し、この冷却損失Ｑｗに基づき点火時期を補正する。 - 特許庁

When rich combustion control is performed, a combustion determination index Kcr calculated from a relationship between an equivalent ratio ϕ and ignition delay time IgD with respect to cylinder inner pressure Cp (the amount of gas recirculated) is used, and the opening of an EGR valve is controlled so that the combustion determination index Kcr is reduced.例文帳に追加

リッチ燃焼制御を実行時に、等量比φと筒内圧力Ｃｐ（還流させる排気ガスの量）に対する着火遅れ時間ＩｇＤの関係から算出される燃焼判定指数Ｋｃｒを用い、燃焼判定指数Ｋｃｒが小さくなるようにＥＧＲ弁の開度を制御する。 - 特許庁

And the ECU reads the fuel increase correction coefficient ke corresponding to the start mode flag Fs and catalyst deterioration index from a correction coefficient setting map (S320 and S330), calculates the fuel injection volume required during start based on the read fuel increase correction coefficient ke (S340), and makes fuel injection and ignition control using the calculated fuel injection volume (S350).例文帳に追加

そして、始動形態フラグＦｓと触媒劣化指数とに対応する増量補正係数ｋｅを補正係数設定用マップから読み出し（Ｓ３２０及びＳ３３０）、読み出した増量補正係数ｋｅに基づいて始動時燃料噴射量を算出し（Ｓ３４０）、その噴射量の燃料を用いて燃料噴射制御及び点火制御を行なう（Ｓ３５０）。 - 特許庁
