Abstract
An improved choke valve control arrangement whose regulating thermostat is heated by a separate electric heater is described. The thermostat heater is coupled to the vehicle power supply through one of a first plurality of switch controlled paths of difference impedance. Each path corresponds to a different rate of opening of the choke valve as a function of engine temperature. A separate room heater arranged to absorb heat from the engine cooling water is coupled to the power supply through a second plurality of switch controlled paths. A ganging arrangement for the switches associates corresponding pairs of paths of the thermostat and room heaters so that a change in the excitation of the room heater is accompanied by a proportional change in the rate of heating of the thermostat heater.
