Abstract
An engine includes an engine body and an air induction system. The engine body includes a cylinder block defining a cylinder bore in which a piston reciprocates. A cylinder head member closes an end of the cylinder bore to define a combustion chamber together with the cylinder bore and the piston. The air induction system is arranged to introduce air into the combustion chamber. The induction system includes a first intake conduit through which the air flows to the combustion chamber. A first plenum chamber unit is disposed upstream of the first intake conduit. A control mechanism is arranged to control an amount of the air flowing through the first intake conduit. The induction system also includes a second intake conduit through which the air flows to the combustion chamber. A second plenum chamber unit is disposed upstream of the second intake conduit. The second intake conduit is coupled with the first intake conduit downstream of the control mechanism.
