摘要： A carburetor may include a body having a main bore from which a fuel and air mixture is discharged for use by an engine, a throttle valve head, a choke valve head and a flow directing feature. The throttle valve head may be carried by the body and is mo veable between an idle position and a wide open position to control at least some fluid flow through the main bore. The choke valve head may also be carried by the body and is moveable between a first position and a second position to at least in part control fluid flow through the main bore. And the flow directing feature associated with the choke valve head or the throttle valve head may alter at least one of the velocity or direction of at least a portion of the fluid that flows in the main bore.

摘要： A starter system (400), for an internal combustion engine (200) including a carburetor (450) and a recoil starter (150), may include a sensor (420), a controller (430) and an actuator (440). The carburetor (450) may have at least a choke valve (322) for controlling a flow of a fresh air into a combustion chamber (232) of the engine (200) during engine start. The choke valve (322) may have a choke position and an open position and may be positioned into the choke position at engine start. The recoil starter (150) may start a rotation of an engine crankshaft causing a fuel supply to the combustion chamber (232) of the engine (200). The sensor (420) may be disposed to detect movement parameters associated with the engine (200) or crankshaft responsive to operation of the recoil starter (150). The controller (430) may be operably coupled to the sensor (420) to receive information indicative of the movement parameters and providing a control signal based on processed information providing an indication of an optimal condition for engine start. The actuator (440) may be configured to receive the control signal from the controller (430) and to initiate automatic repositioning of the choke valve (322) from the choke position to the open position based on receiving the control signal from the controller (430) responsive to the indication of the optimal condition for engine start.
