Abstract
In an electronically controlling, fuel injection method, wherein an electromagnetic fuel injection valve is controlled so as to control an amount of alcohol-containing-fuel being supplied into an intake system, a difference between a basic amount of fuel being injected and an actual amount of fuel being injected, or a ratio of the former to the latter, is stored in closed loop controlling in which an actual amount of fuel being injected is calculated by using air-fuel-ratio-feedback signals as parameters, the aforesaid basic amount of fuel being injected being calculated from operational parameters of the engine, besides an air-fuel ratio, and the aforesaid actual amount of fuel being injected being calculated by correcting the basic amount of fuel being injected on the basis of air-fuel-ratio-feedback signals; and the basic amount of fuel being injected is corrected on the basis of the aforesaid difference or ratio in open loop controlling, thereby calculating the actual amount of fuel being injected.
