Abstract
An auto choke device for an engine includes a choke valve for varying the opening of an intake passage of the engine, and a starter motor for starting the engine. Upon activation of the starter motor, the choke valve starts valve opening motion from a fully closed position. The choke valve continues the valve opening motion at a certain valve opening speed until it achieves a start opening set based on the temperature of the engine.
