AUTOMATIC AIR INLET CONTROL SYSTEM FOR AN ENGINE

摘要

An automatic choke for a small internal combustion engine uses an air vane (28) responsive to an air flow created by a radial fan (20) to position the choke valve (40) during engine starting. A return spring (44) or gravity may be used to reset the automatic choke after the engine has been stopped. The automatic choke includes a thermally-responsive device (49) that keeps the choke at least partially open during hot restarts of the engine.
