Way actual electric current of the capacity control valve which controls the fuel supply tonnage for the high tension pump which forces the high tension fuel

摘要

The occasion where ignition switch 11 is turned on, the initial value in integral calculus calculating which calculates integral calculus value of difference of target electric current and actual electric current of flow control valve 6, in flow control valve 6 at that time as target electric current is designated as specified value in order to turn on electricity, after (S102 and S104), ignition switch 11 as on between predetermined times To, although integral calculus gain K in integral calculus calculating, is designated as bigger 2nd integral calculus gain 1st than integral calculus gain K1 of the time K2 usually after predetermined time To lapse, integral calculus gain the aforementioned 1st integral calculus gainBy making K1 (S106 - S108), integral calculus value in the time of starting early point to the setting, it has become something which can assure the improvement of stability and responsiveness of rail pressure control.
