Definitions

  • the invention is based on a method having the features specified in the preamble of claim 1. Such a method is in the article "The electronically controlled glow system ISS for diesel engines, published in the DE-Z MTZ Motortechnische Zeitschrift 61, (2000) 10, pp. 668-675 , known.
  • FIG. 1 shows the block diagram of a glow plug control unit 1 for carrying out the known method.
  • This control unit includes a microprocessor 2 with integrated digital-to-analog converter, a number of MOSFET power semiconductor 3 for switching on and off an equal number of glow plugs 4, an electrical interface 5 for connection to a motor control unit 6 and an internal power supply 7 for the microprocessor 2 and for the interface 5.
  • the internal power supply 7 has connection with the vehicle battery via the "terminal 15" of the vehicle.
  • the microprocessor 2 controls the power semiconductors 3, reads their status information and communicates via the electrical interface 5 with the engine control unit 6.
  • the interface 5 makes an adjustment of the signals required for communication between the engine control unit 6 and the microprocessor 2.
  • the power supply 7 supplies a stable voltage for the microprocessor 2 and for the interface 5.
  • Glow plugs have the task of causing a cold start of the diesel engine, a secure ignition of the fuel-air mixture and then effect in a Nachglühphase a smooth running of the diesel engine until it is so warm that it runs evenly without support by glow plugs ,
  • the afterglow phase lasts up to several minutes.
  • the glow plug should assume a constant temperature, the steady-state temperature, for which with steel glow plugs approximately 1000 ° C is a typical value.
  • modern glow plugs do not require the full voltage from the vehicle electrical system, but only a voltage of typically 5 volts to 6 volts.
  • the microprocessor 2 controls the power semiconductors 3 for this purpose by a method of pulse width modulation, with the result that the voltage from the electrical system, which is the power semiconductors 3 via the "terminal 30" of the vehicle is modulated so that the desired voltage is applied to the glow plugs in the time average.
  • the control unit 1 supplies the glow plugs 4 with a higher heating voltage of, for example, 11 volts in order to achieve a temperature of the glow plugs as quickly as possible in the amount of steady-state temperature or - preferably - still some 10 ° C temporarily.
  • the rapid heating of the glow plugs in the pre-glow phase is energy-controlled, ie, the respective glow plug is supplied with an energy which is predetermined so that the steady-state temperature is reached in any case.
  • the steady-state temperature is initially exceeded once and then decreases to the steady-state temperature.
  • the engine After a cold start, the engine is for a certain period of time in the so-called cold run phase, which is characterized by an idle speed, which is above the idle speed with warm engine.
  • the effective voltage applied to the glow plugs i.e. the voltage averaged over time due to pulse width modulation, is determined by the initial heating voltage of e.g. 11 volts (the "initial value") gradually lowered to a voltage of e.g. 6 volts (the "final value" of the voltage) at which the steady state temperature of the glow plugs of e.g. 1000 ° C can be maintained. Fluctuations in the vehicle electrical system voltage can be compensated during pulse width modulation by changing the switch-on time.
  • the gradual lowering of the voltage applied in the mean time to the glow plugs 4 voltage in the cold running phase takes place during a predetermined period of time according to empirical values that are stored in the microprocessor 2.
  • the period of time during which the effective stress is raised in the cold-running phase is at most as long as the cold-running phase itself, preferably shorter than this.
  • the glow plugs are cooled to different degrees.
  • the electric power supplied to the glow plugs is adjusted to the changing conditions. This is done in accordance with the specifications of the engine control unit 6 by raising or lowering the final value of the voltage applied to the glow plugs 4 on average over time.
  • the engine control unit decides on the basis of evaluations that it makes itself, when annealing processes are triggered and how long they last.
  • the engine control unit has an intelligence that is exercised by means of a state machine, which is integrated in the engine control unit.
  • the state machine operates according to a rigid, fixed scheme and generates command signals which are transmitted to the usually mounted on the engine block glow plug control unit, which implements the specification of the engine control unit and taking into account a stored in the glow plug control unit Model of the glow plugs controls the electrical power supplied to the glow plugs. This requires a mutual adaptation of the two control devices and the algorithms running in them, as far as they relate to the control of the glow plugs.
  • the present invention has for its object to reduce the cost of realizing the control of glow plugs.
  • the inventive method for operating glow plugs which have a housing and a projecting over the housing glow element, in a diesel engine, which cooperates with a motor control unit and a glow plug control device, which following a Vorglühphase the glow plugs supplied electrical power in response to a Controlled by the engine control unit specification is controlled, characterized in that the engine control unit determines a size which is a measure of a temperature that is to occur on the glow element.
  • This quantity is transmitted by the engine control unit as a target to the glow plug control device, which converts this target specification with an algorithm stored in the glow plug control device and taking account of characteristic values which are likewise stored in the glow plug control device.
  • the engine control unit determines the target temperature for the glow element of the glow plug in an advantageous manner depending on the operating state of the diesel engine. It is not only a consideration of the current operating condition of the diesel engine in question, but also the previous development of the operating condition of the diesel engine, which can observe the engine control unit with the aid of sensors associated with it, be taken into account in determining the target for the temperature. This allows a faster response to changes in the operating state of the diesel engine, which can be predicted based on the observed past development even for a certain period of time.
  • the effectiveness of a glow plug depends primarily on the surface temperature of the glow element of the glow plugs.
  • the surface temperature is therefore the primary objective for the specification to be determined by the engine control unit.
  • the surface temperature of the glow element of the glow plugs can not be measured directly in the diesel engine.
  • the glow plug controller includes the type of engine, the glow plug type, the electrical resistance of the glow plugs at a reference temperature, the dependence of the electrical resistance of the glow plug on the temperature
  • the heat capacity of the glow plugs the cooling behavior of the glow plugs in dependence on the speed of the engine, the coolant temperature and the sign of a speed change of the engine, and the heat supply from burns under one or more selected load conditions of the engine.
  • Limit and threshold values which limit the conversion of the target specification transmitted by the engine control unit in the annealing control unit can also be taken into account with advantage; so z.
  • Example be ensured that a transmitted from the engine control unit target for the temperature of the heating element, which would overload the glow plugs used, is limited to a value that is still beneficial for the glow plugs used.
  • the target of the engine control unit for the temperature of the glow element can therefore be interpreted in an advantageous development of the invention of the glow plug control and adapted to the type of glow plug used after the glow plug control device has determined himself or he has been entered the glow plug control unit.
  • the adaptation may be an increase or decrease in the temperature specification and a change in the temperature curve leading thereto, which could be determined from a pattern characteristic curve of a glow plug stored in the glow controller by modifying the pattern characteristic.
  • the coolant temperature can be used to form a limit, z. B. in such a way that a target of the engine control unit for a higher glow plug temperature is disregarded to protect the glow plugs when and as long as the coolant temperature exceeds a threshold.
  • the glow plug control device can take into account in the implementation of the target with advantage parameters which are supplied to it from the outside, preferably from the engine control unit, namely z.
  • the fuel injection rate per clock the coolant temperature, the speed of the diesel engine, the sign of a speed change of the diesel engine and the temperature of the incoming into the cylinder of the diesel engine combustion air.
  • the Glüh horrinology can also the maximum possible temperature z. B. consider when using steel glow plugs. It may limit or interpret the predetermined temperature based on the type of glow plug detected or communicated by the glow controller.
  • the target value for the temperature of the glow element is determined by the engine control unit so that a basic temperature for the afterglow phase is initially set and that a lower temperature than the base temperature in one or more of the following cases is specified as a target:
  • the diesel engine is in overrun mode ( in this case, the fuel supply may be switched off);
  • the coolant temperature exceeds a threshold (the higher the coolant temperature, the more likely it is possible to dispense with hot glow plug combustion support);
  • the temperature of the combustion air entering the cylinders exceeds a threshold (an increase in the temperature of the combustion air increases the ignitability of the mixture and allows the glow plug temperature to be lowered);
  • the voltage of the electrical power source present in the vehicle (vehicle electrical system voltage) falls below a limit (as a precaution, the current drain from the vehicle electrical system is limited if this is too weak).
  • a higher temperature than the previously specified by the engine control unit temperature can from the engine control unit z. B. be given if one or more of the following cases exist:
  • the pollutant content in the exhaust gas of the diesel engine exceeds one or more limits (in this case, an increase in the Glow plug temperature to assist combustion); a coasting phase of the diesel engine is ended (the glow plug, which has become colder during the coasting phase, is reheated for the following load case); the coolant temperature falls below a threshold as it occurs in prolonged stop-and-go operation (an increase in the glow plug temperature promotes combustion and reduces pollutant emissions, which is particularly important in city traffic); the temperature of the combustion air entering the cylinders falls below a threshold (an increase in the glow plug temperature promotes combustion and reduces pollutant emissions); the fuel injection amount or load of the diesel engine increases and / or exceeds a threshold (the glow plug may act to assist combustion at least temporarily with combustion support); during annealing to assist the regeneration of a particulate filter present in the exhaust line of the
  • a matrix of correction values can be stored in the glow plug control device with which the supply of electrical energy to a glow plug intended for a standard case is corrected as a function of the rotational speed and the instantaneous fuel consumption (eg in mm 3 per stroke).
  • the matrix contains the correction values for discrete value pairs of speed and consumption. The energy supply to the glow plugs tends to increase with increasing speed and decreases with increasing consumption.
