Title: Air-fuel ratio controlling device for internal combustion engine
Inventor: ASADA KIYOSHI
IPC: F02D41/20
Filed: 1991-06-10
Abstract: PURPOSE:To restrict disturbance in an air-fuel ratio in a transition period by controlling a fuel injection quantity with a transition determining means, a predicting means, a computation means, and a prediction prohibiting means. CONSTITUTION:A transition determining means M1 determines if a time is in a transition period in which a throttle opening is changed quickly or not. A predicting means M2 predicts a suction air quantity in the transition period based on the throttle opening and an engine rotation number, and a computation means M3 computes and controls a fuel injection quantity using a suction air quantity detected at a time other than the transition period, or a predicted suction air quantity instead of the detected suction air quantity in the transition period. A prediction prohibiting means M5 compares the first threshold value, which becomes larger as the rotation number is larger, and the second threshold value of a predetermined small value with the throttle opening, and prohibits prediction of the suction air quantity when the throttle opening exceeds the first threshold value, or when it is the second threshold value or less. At the time of prohibition, the computation means M3 computes the fuel injection quantity, thereby disturbance in air-fuel ration control by difference between the predicted and the actual suction air quantity can be restricted.
