Description
ここで、TBは基本燃料噴射時間、FAFはフィードバック補正係数、kIは増量補正係数、kFは性状補正係数をそれぞれ表している。
ここで、kFfは給油後に遮断弁20が閉弁されているときの給油室19f内の燃料の性状を表す性状補正係数を示している。
したがって、性状補正係数kFfは次式(3)で表される。
そこで本発明による実施例では、性状補正係数kFaを算出すべきときには(図6のt4)、まず遮断弁20を閉弁したまま給油室ポンプ27f及び残存燃料室ポンプ27r両方を運転し、このとき得られるフィードバック補正係数FAFの平均値FAFAの変化量から性状補正係数kFqを算出し、次いで式(3)から性状補正係数kFfを算出し、次いで式(2)から性状補正係数kFaを算出するようにしている。
