Abstract:
A control apparatus for controlling an internal combustion engine comprising computing means for computing the fuel supply of the internal combustion engine at each engine cycle based on engine parameters of said internal combustion engine and control means for controlling a fuel injector to supply to said internal combustion engine according to the amount of fuel supply computed, wherein said computing means includes;first means for generating a first detection signal when said first means detects a change in a throttle opening level of said internal combustion engine from a low opening level which is lower than a predetermined opening level to a non-low opening level which is higher than said predetermined level,second means for generating a second detection signal when said second means detects that a variation .DELTA..theta..sub.TH in said throttle opening level is equal to or greater than a predetermined value,third means for generating a first increment correction value at each fuel injection of a predetermined number of fuel injections from the generation of said first detection signal and thereafter generating a second increment correction value according to an amount of said variation .DELTA..theta..sub.TH as long as said second detection signal is generated, andfourth means for correcting the amount of fuel supply in accordance with said second increment correction value.
