ABSTRACT:
An internal combustion engine provided with an EFI (electronic fuel injection) system, in which the ratio of the amount of air introduced into the engine intake system to the amount of fuel supplied to the combustion chamber is controlled to a predetermined constant ratio irrespective of engine operating conditions, is disclosed. A part of the introduced air is diverted from the intake pipe in accordance with the engine operating condition, and is introduced into the exhaust system or re-introduced into the intake system of the engine when the engine is operating under particular conditions. Thus, a rich air-fuel mixture, which is, for example, suitable for a particular engine operating condition, can be supplied to the engine combustion chamber.
