ABSTRACT:
An automatic choke system of modular construction has self-regulating heaters arranged to heat a thermostatic spring to adjust a choke valve during start-up of an automotive engine. Heat storing and transferring means are located between the heaters and spring to provide heat-transfer paths of different lengths between the respective heaters and the spring for providing the thermostatic spring with non-linear heat up to improve the smoothness of initial engine operation while also minimizing the period of fuel-enriched operation during start-up. The same heat storing and transferring means is also provided with a large heat storing capacity for continuing to transfer heat to the spring after termination of engine operation to prevent any substantial fuel enrichment by the choke system if the engine should be restarted before selected portions of the engine cool below selected fuel vaporizing temperatures.
