Abstract
The heating glow plug controller for diesel engines is capable of controlling the activation of the glow plugs and consists of a set of electronic relays which in addition can also detect failures due to open circuit or short-circuit, and then acting in under 1 millisecond since electronic relays are semiconductors and no electromechanical elements are involved. There is one electronic relay per glow plug and each one may consist of a separate semiconductor wafer or alternatively, several relays may be integrated in a single semiconductor wafer. The set of relays is in turn connected to controlling or calculating module, and may even be included in the same block as the calculator module or in a different one connected by connectors and leads to the calculator block.
