Engine auxiliary starting device
An engine auxiliary starting device for leading fuel evaporative gases produced in a float chamber to a canister and for supplying the fuel evaporative gases condensed by the canister to a fuel tank is described comprising: an electromagnetic valve which includes a bobbin made of a nonmagnetic material and having an inlet port and outlet port formed therein; a solenoid coil wound on the bobbin; an inner core positioned in a central bore formed in the bobbin; a yoke member made of magnetic material and secured on the bobbin for forming a magnetic circuit with the inner core and the solenoid coil; a valve member positioned so as to be attracted by the inner core upon energization of the solenoid coil; a housing secured to the bobbin; and sensor means for detecting a predetermined temperature upon stopping of the engine and timer circuit means responsive to a detection of at least the predetermined temperature by the sensor means for supplying an electric current to the solenoid coil to open the valve member for a predetermined time. The sensor means and time circuit means comprise an integrated circuit board positioned in the housing.
