ABSTRACT:
A method for electronically controlling fuel metering means for metering the quantity of fuel being supplied to an internal combustion engine, wherein a basic fuel quantity corresponding to a condition in which the engine is operating is corrected by the use of a first correction coefficient having a value dependent upon the engine temperature, so as to supply a required quantity of fuel to the engine. When the engine is accelerated while it is in a cold condition, the value of a second correction coefficient is set as a function of the value of the first correction coefficient, and the above basic fuel quantity is corrected by the value of the second correction coefficient thus set. Preferably, the basic fuel quantity is corrected in such a manner that an acceleration fuel increment dependent upon an accelerating condition of the engine is multiplied by the value of the second correction coefficient, and the resulting product is added to the basic fuel quantity. The second correction coefficient is applicable to both synchronous acceleration fuel increasing control synchronized with generation of a signal indicative of a predetermined crank angle of the engine, and asynchronous acceleration fuel increasing control effected independently of the above signal.
