ABSTRACT:
An internal combustion engine having a relatively large main induction system that supplies the engine charge requirements at partial and full load and a relatively small cross-sectional area auxiliary induction system that provides the charge requirements at idle and low load conditions. An exhaust gas recirculating system is also incorporated with a control whereby exhaust gases are recirculated to the engine combustion chambers only at the time when the auxiliary induction system is supplying the major portion of the engine charge requirements. This permits effective combustion control without necessitating modifications to the conventional spark timing device of the engine.
