31RCWO185 515-84-0010/002a AN ELECTRONIC CONTROLLER FOR PREDETERMINED TEMPERATURE COEFFICIENT HEATER Abstract of the Disclosure An electronic controller for a predetermined temperature coefficient heater provides solid state control of the application of power to the heater. In particular, a positive temperature coefficient glow plug wherein the heater is plated on a ceramic substrate glow plug is controlled by contactless solid state controller. The temperature of the glow plug is sampled by a clock signal and compared with a predetermined temperature value. Pulse power is supplied to elevate and maintain the temperature of the heater to the predetermined value. In a complete motor vehicle engine wherein one glow plug is used in each cylinder, one glow plug is sampled and controls the remainder of the plugs. (FIGURE 1)
