摘要:
A method for heating a glow plug for a diesel engine to its desired temperature by supplying power to the glow plug in a controlled fashion. During a certain time interval after termination of a previous glow process, a mathematical model is used to determine the values for the supply of power to the glow plug, which includes the values of the actual thermal state of the glow plug, the time elapsed since the end of the previous glow process and the parameters of the diesel engine relevant for a glow process.

A process and device for controlling the heating of the glow plugs of a diesel engine. To be able to take into consideration the thermal behavior of the glow plugs while controlling the current supply of the glow plugs (3) of a diesel engine, the thermal behavior of the glow plugs (3) is emulated via a physical model. Formed on the corresponding output signal of the model (4), which is proportional to the glow plug temperature, is a reference signal, which as a control value, lies on the electronic control (12) controlling the heating flow of the glow plugs (3), which accordingly controls the heating of the glow plugs (3) using the actual glow plug temperature determined from emulation.
摘要:
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.

摘要:
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.

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.
摘要:
The invention describes a method for operating glow plugs, that comprise a housing and a heater element projecting beyond that housing, in a diesel engine which interacts with an engine control unit and a glow plug control unit which latter, following a preheating phase, controls the electric power supplied to the glow plugs in response to an input received from the engine control unit. It is provided according to the invention that the engine control unit determines a value representative of a temperature that is to be reached at the heater element and the engine control unit transmits that value as target value to the glow plug control unit which implements that target value using an algorithm stored in the glow plug control unit and with reference to characteristic values stored in the glow plug control unit.
