摘要： An engine starting system that includes a power source (320), an electromagnetic coil (330) and core (335), and a choke valve (340) disposed in an air intake of an air/fuel-mixing device of an internal combustion engine. At the time of starting the engine, the power source outputs an electrical signal to an electromagnetic coil and core, inducing a magnetic field from the electromagnetic coil and the core. The magnetic field from the core moves the choke valve toward a substantially closed position that enriches an intake mixture of fuel and air to the engine during starting. In one embodiment, the power source includes a moving magnet (325) that interacts with a stator coil to provide the electrical signal to the electromagnetic coil. In another embodiment, the closing of a starter switch allows a battery to provide the electrical power to the electromagnetic coil.
