Abstract
An intake system is provided for a barrel internal combustion engine. The intake system includes a main air inlet, an intake plenum for a plurality of combustion cylinders, a first throttle, a second throttle and a control unit. The first throttle is operative to control a flow of air from the main air inlet, through a charging unit, and to the intake plenum. The second throttle is operative to control a flow of air from the air inlet to the intake plenum. The control unit controls the operation of the first and second throttles in supercharged or normally aspirated modes, where the first throttle operates as a main throttle and the second throttle is closed in the supercharged mode, and where the first throttle is closed and the second throttle operates as the main throttle in the naturally aspirated mode.
