Exhaust gas recirculation control means for multiple cylinder engine having means for controlling air-fuel ratio in accordance with a signal from an exhaust gas sensor
A multiple cylinder engine is disclosed including a first group of cylinders having a first intake passage which is provided with an air-fuel mixture of a predetermined ratio in accordance with the signal from an exhaust gas sensor provided in the exhaust passage from the first group of cylinders. The engine further includes a second group of cylinders having a second intake passage which is provided with a mixture having an air-fuel ratio which is of a predetermined relationship with respect to the air-fuel ratio of the mixture into the first group of cylinders, the predetermined relationship being determined in accordance the engine operating condition. An exhaust gas recirculation system is provided for controlling the recirculation gas flow to the second intake passage with respect to the recirculation gas flow to the first intake passage in accordance with the engine operating condition.
