ABSTRACT:
A fuel supply system for an automotive engine has a thermal control regulating choke valve movement in a carburetor to provide smooth engine starting at various ambient temperatures while achieving improved fuel efficiency and pollution emission control. Motion transfer means in the control include cam, cam follower and gear means which are arranged between an electrically-heated, thermally-responsive spring and an additional spring to adapt the control to meet the performance requirements of a particular carburetor or engine. Movement of the thermally-responsive spring in response to temperature change moves the additional spring to provide any linear or non-linear changes in choke valve biasing force which may be desired for improving engine performance during engine warm up.
