Abstract: Method for heating an electrical heating element, for example, a glow plug for an internal combustion engine, from an initial temperature to the operating temperature. In order to prevent the heating element from overheating in cases where the initial temperature is higher than a set temperature that is normally taken as a basis, the actual initial temperature of the heating element is first determined, and an amount of electrical power depending on the level of the determined initial temperature is supplied to the heating element. In this way, the supplied amount of electrical power is reduced at higher initial temperatures, thus preventing the heating element from becoming overheated to a temperature at which damage can occur.

Abstract: The invention relates to a method and a device for automatic starting of a diesel engine, actuation of the ignition key (1) initiating preheating (2) and turnover of the engine by the starter (3) and fuel injection (4) being triggered at the earliest when the minimum temperature of the glow plugs (2′) required for starting of the engine has been reached.
Abstract: A method and device for controlling the heating of the glow plugs in a diesel engine, wherein the engine temperature is determined, independently of initialization of the engine control system and following a signal for starting the engine, by a sensor communicating with the glow control system. A glow command is generated if the engine temperature is below a predetermined value. Commencement of the heating procedure is automatically determined by the glow control system independently of initialization of the engine control system, and heating of the glow plugs can start prior to completion of initialization of the engine control system. The time required for the completion of initialization of the engine control system can be saved during heating of the glow plugs.

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.
