| description | PROBLEM TO BE SOLVED: To prevent the air fuel ratio in the transient condition from being deviated from the target value by correctly calculating the basic injection amount in the transient condition at an injection valve part even when a throttle valve opening sensor is deteriorated. SOLUTION: The learned value of the coefficient to determine the degree of the response in the transient condition is stored in a storage means 32 with the air intake throttle valve opening as the parameter. The learned value is read by a reading means 34 based on the detected value of the throttle valve opening, the basic pulse width at an injection valve part is operated by an operating means 35 from the read learned value and the detected value of the sucked air volume, and the fuel of the basic injection amount at the injection valve part is fed by opening the fuel injection valve by a driving means 36. The pressure in an air intake pipe on the downstream side of the throttle valve is detected by a detecting means 37, and the learned value to the throttle valve opening is updated by an updating means 38 based on the change of the pressure in the air intake pipe. |
