ABSTRACT:
An electrical heating means for the bimetallic thermostatic spring controlling a carburetor automatic choke valve is in series with a negative temperature coefficient thermistor which senses engine temperature to open the choke valve in a more efficient manner and improve engine performance during warm-up. A temperature responsive switch is in series with the heater, negative temperature coefficient thermistor and a battery and senses engine block temperature to maintain current flowing in the heater after the engine is shut off and until the entire engine cools down, to provide better warm-engine restarts and reduce pollution.
