Claim 1
Independent Claim
287 words
A method of controlling an operating amount of an operation control means for controlling the operation of an internal combustion engine having an intake passage, and an intake air quantity control means arranged in said intake passage for adjusting the opening area of said intake passage, the operating amount of said operation control means being controlled in a first arithmetic manner to a first desired value determined on the basis of a first operating parameter of the engine when the engine is operating in a predetermined operating condition, while it is controlled in a second arithmetic manner to a second desired value determined on the basis of a second operating parameter of the engine when the engine is operating in a condition other than said predetermined operating condition, the method comprising the steps of: (1) detecting the pressure of intake air upstream of said intake air quantity control means; (2) when the engine is operating in said predetermined operating condition, determining a first correction value appropriate to said first arithmetic manner, as a function of the detected value of intake air pressure, correcting said first desired value of operating amount by the use of the determined first correction value, and controlling the operating amount of said operation control means to the corrected first desired value; and (3) when the engine is operating in a condition other than said predetermined operating condition, determining a second correction value appropriate to said second arithmetic manner, as a function of the detected value of the intake air pressure, correcting said second desired value of operation amount by the use of the determined second correction value, and controlling the operating amount of said operation control means to the corrected second desired value.

A method of controlling an operating amount of an operation control means for controlling the operation of an internal combustion engine having an intake passage, and an intake air quantity control means arranged in said intake passage for adjusting the opening area of said intake passage, the operating amount of said operation control means being controlled in a first arithmetic manner to a first desired value determined on the basis of a first operating parameter of the engine when the engine is operating in a predetermined operating condition, while it is controlled in a second arithmetic manner to a second desired value determined on the basis of a second operating parameter of the engine when the engine is operating in a condition other than said predetermined operating condition, the method comprising the steps of: (1) detecting the pressure of intake air upstream of said intake air quantity control means; (2) when the engine is operating in said predetermined operating condition, determining a first correction value appropriate to said first arithmetic manner, as a function of the detected value of intake air pressure, correcting said first desired value of operating amount by the use of the determined first correction value, and controlling the operating amount of said operation control means to the corrected first desired value; and (3) when the engine is operating in a condition other than said predetermined operating condition, determining a second correction value appropriate to said second arithmetic manner, as a function of the detected value of the intake air pressure, correcting said second desired value of operation amount by the use of the determined second correction value, and controlling the operating amount of said operation control means to the corrected second desired value.
Claim 3
Dependent Claim
23 words
A method as claimed in claim 1, wherein the intake air pressure upstream of said intake air quantity control means is atmospheric pressure.
Claim 4
Dependent Claim
33 words
A method as claimed in claim 1, wherein said first operating parameter of the engine is the opening area of said intake passage which is adjusted by said intake air quantity control means.
Claim 5
Dependent Claim
32 words
A method as claimed in claim 1, wherein said second operating parameter of the engine is pressure in said intake passage at a location downstream of said intake air quantity control means.
Claim 6
Dependent Claim
21 words
A method as claimed in claim 1, wherein said predetermined operating condition is a low load operating condition of the engine.
Claim 7
Dependent Claim
39 words
A method as claimed in claim 1, wherein said operation control means is a fuel supply quantity control means, said operating amount being the quantity of fuel being supplied to the engine by said fuel supply quantity control means.
Claim 8
Dependent Claim
91 words
A method as claimed in claim 6, wherein said first correction value is set to such a value that said first desired value of operating amount corrected by said first correction value decreases with a decrease in the intake air pressure upstream of said intake air quantity control means, and said second correction value is set to such a value that said second desired value of operating amount corrected by said second correction value increases with a decrease in the intake air pressure upstream of said intake air quantity control means.
