Method of controlling operating amounts of operation control means for

Abstract

A method of electronically controlling an operating amount of a control means for controlling operation of an internal combustion engine, such as a fuel injection control means. When the engine is operating in a predetermined low load condition, a desired operating amount of the control means is determined in dependence on the detected value of a first engine operating parameter indicative of loaded conditions of the engine, whereas when the engine is not operating in the predetermined low load condition, the desired operating amount of the control means is determined in dependence on the detected value of a second engine operating parameter indicative of loaded conditions of the engine. In addition, first and second provisional desired operating amounts of the control means are determined, respectively, in dependence on the detected values of the first and second engine operating parameters when it is detected that the engine has entered the predetermined low load condition from a condition other than the predetermined low load condition. The desired operating amount of the control means is determined in dependence on the second provisional desired operating amount from the time it is detected that the engine has entered the predetermined low load condition to the time the second provisional desired operating amount becomes substantially equal to the first provisional desired operating amount, even while the engine is actually operating in the predetermined low load condition. The control means is controlled on the basis of the desired operating amount thus determined.
