    摘要: An internal combustion engine employing a siamesed exhaust port arrangement is equipped with a secondary air supply system which is arranged to induct atmospheric air into the exhaust system of the engine in response to the pressure pulsation in the exhaust port. At least two air injection nozzles are disposed open to portions of the exhaust port where they are not affected by the interaction of the pressure pulsations caused by the strokes of two adjacent engine cylinders.
