Title: Control device for air-fuel ratio of internal combustion engine
Inventor: DEMURA TAKAYUKI
IPC: F02D41/22
Filed: 1989-07-20
Abstract: PURPOSE:To control air-fuel ratio to a target value by deciding blinding of an air assist passage from a deviation between air-fuel ratio study values at the time of low and high load operation and changing a correction value of control error of air-fuel ratio, generated by a differential pressure between an intake pressure in the passage and a pressure in an intake pipe, into a small value corresponding to a high load operational region. CONSTITUTION:Opening time of a fuel injection valve M1 is calculated in accordance with an operative condition by a valve-open time calculating means M5 and corrected to target air-fuel ratio by an air-fuel ratio correcting means M7. A fuel injection pressure is governed to a high predetermined value for an intake pipe pressure by a pressure governing means M3. Since the valve opening time or the fuel injection pressure is corrected by an injection fuel correcting means M8 being based on a parameter for showing a difference between an intake pressure in an air assist passage N4 and the intake pipe pressure, air-fuel ratio can be stably controlled to a target value by compensating a fluctuation of a fuel injection amount. While a study value for showing the displacement from the reference value of a correction value in the air-fuel ratio correcting means 7 is calculated in each low and high load operational region by a study value calculating means M9, when the deviation is not less than a predetermined value, the correction value of the valve opening time or the fuel injection pressure is changed into the predetermined value corresponding to the high load operational region by a correction value changing means M10.
