ABSTRACT:
A positive temperature coefficient resistor element of the type that has a substantially constant resistance value when the temperature thereof is less than a selected value and that displays a rapid rise in resistance value when the temperature thereof reaches and increases beyond the selected value is mounted in thermal communication with a Diesel engine and is arranged to be electrically energized and deenergized simultaneously with the engine glow plug energizing circuit. An associated electrical switching arrangement is effective to complete the respective glow plug and resistor element energizing circuits across an operating potential source in response to the application of operating potential and, thereafter, is effective to alternately interrupt and complete the respective glow plug and resistor element energizing circuits in response to the electrical signal developed across the resistor element attaining a predetermined potential level and in response to the electrical signal developed across the resistor element attaining another predetermined potential level, respectively, to cyclically complete and interrupt the glow plug energizing circuit.
