    Abstract: An internal combustion engine (2) includes a crankcase (4) including a crankshaft and at least one cylinder (6; 61, 62, 63, 64) coupled to the crankcase. The at least one cylinder has an intake port (14) and defines an internal combustion chamber (10). The engine further includes a throttle body assembly (20) with a throttle valve (22) coupled to the intake port of the at least one cylinder and a throttle plate (26). Additionally, the engine includes a supplementary air inlet (42) fluidly coupled to the intake port and spaced apart from the throttle valve. The supplementary air inlet is configured to receive a flow of air from a location downstream of the throttle plate when the throttle plate is in a fully closed position and the flow of air is directed into the combustion chamber through the intake port for combustion therein.
