ABSTRACT:
A feedback control is effected during warming-up operation so as to adjust an actual air-fuel ratio to a target value. A sensing element is used to probe exhaust gases to detect an air-fuel ratio of a fuel-rich mixture that is required for warming up the engine. The amount of fuel injection is corrected so that the actual air-fuel ratio is adjusted to a target value displaced to the rich side from the stoichiometric ratio.
