Abstract
An AC glow plug system is provided that includes a static converter for DC to AC conversion. Control techniques include varying the converter duty cycle according to glow plug temperature and other parameters such as engine air or coolant temperatures for smooth running as well as for prolonging glow plug life. Control is also varied according to fuel system characteristics and fuel composition.
