Abstract
A method and system for controlling an amount of fuel supplied into an internal combustion engine. The system comprises: (a) first means for detecting and signalling an air quantity sucked into an intake passage of the engine; (b) second means for storing at least one first dynamic characteristic model expressing a transfer function defined between a detected air quantity value and intake air quantity actually sucked into each engine cylinder; (c) third means for calculating an actual intake air quantity to be sucked into each engine cylinder from the detected value of said first means and the first dynamic characteristic model stored within said second means; (d) fourth means for storing at least one second dynamic characteristic model expressing a transfer function defined between a signal corresponding to an amount of fuel required for the engine and actual amount of fuel sucked into each engine cylinder; (e) fifth means for calculating the amount of fuel required for the engine using an intake air quantity value calculated by the third means; (f) sixth means for calculating an amount of fuel to be supplied to the engine from the required amount of fuel calculated by the fifth m…
