Abstract: The engine has first and second intake ports for one cylinder (combustion chamber). The intake ports are formed in a cylinder head and extend substantially parallel to each other. Downstream ends of the first and second ports open to a combustion chamber defined in the cylinder upon a compression stroke. The first intake port is a helical port to generate and supply a first swirl into the combustion chamber. The second intake port has a recess in its wall near its downstream end to reverse the flow direction of the air in the second intake port so as to generate and supply a second swirl into the combustion chamber. The recess in the second intake port reverses the air flow direction before the intake air in the second intake port enters the combustion chamber, so that the second swirl flows in the same direction as the first swirl in the combustion chamber. Therefore, a single strong swirl is obtained in the combustion chamber.
