Abstract

See full text

A method is provided for controlling one or more glowplugs in a compression-ignition engine. The controlling of the glowplug involves the prediction of a glow plug temperature to control a power supply to the glowplug. A supplied power to a glowplug and a combustion chamber temperature is determined. A temperature of the glowplug is predicted and the predicted glowplug temperature is used to control a power supply to the glowplug. The predicted glowplug temperature is derived from a numerical solution of a differential equation for the glowplug temperature. The differential equation is nonlinear in the glowplug temperature.
