Method and device for operation of the glow plugs of a Diesel engine
First Claim
1. A method for operation of glow plugs in a Diesel engine, comprising the steps of determining what type of glow plugs are in the engine by detecting at least one of a physical and electrical characteristic of the glow plugs in the Diesel engine and evaluating the characteristics detected with respect to corresponding known glow plug characteristics of the determined type of glow plugs, and controlling operation of the glow plugs in a manner suitable for the type of glow plug that has been determined based upon the results of the detecting and evaluating steps.

Abstract
A method and device for operation of glow plugs of a Diesel engine in which the type of glow plugs used is determined, by a parameter typical of the glow plugs, for example, the electrical glow plug resistance, being detected and evaluated. The detected values of the parameter typical of the glow plugs are compared with corresponding data for various types of glow plugs stored in the glow controller to determine the type(s) of glow plug(s) in the engine. After identification of the type(s) of glow plug(s), stored sets of parameters, which correspond to the type(s) of glow plug(s) determined, are likewise called upon to control the glow plugs.
