Abstract
A throttle valve is supported rotatably on a pipeline. The throttle valve is driven by a motor. A downstream side of the throttle valve is connected to an engine. A means for opening the throttle valve forcedly is provided so as not to allow a tar component in the fuel for driving the engine to stick on the throttle valve at an outer peripheral portion when the engine is shut down.
