Definitions

  • the invention relates to a self-igniting internal combustion engine with a glow plug, which is connected to an electrical resistance measuring device connected to the input of evaluation electronics for determining the electrical resistance of the glow plug.
  • Such internal combustion engines are generally known under the name "diesel engines”.
  • An internal combustion engine of the above type is described in US-A-40 02 882.
  • the evaluation electronics serve to determine the glow plug temperature on the basis of the resistance of the glow plug in order to control the energization of the glow plug in such a way that overheating of the glow plug can be avoided. Information other than the temperature of the glow plug cannot be obtained by the known evaluation electronics.
  • Optimizing the way an internal combustion engine works has recently become increasingly important. Effective control of an internal combustion engine can ensure, for example, optimum efficiency, the lowest possible consumption, the most harmless exhaust gas composition, low noise and the longest possible service life.
  • numerous sensors are installed in the internal combustion engine, which have evaluation electronics with information about the operating behavior supply the internal combustion engine. Unfavorable operating values are then either displayed or automatically changed to favorable operating values by actuating actuators.
  • a disadvantage of the known internal combustion engines is that the arrangement of sensors causes relatively high costs.
  • the temperature inside an internal combustion engine is particularly instructive. Especially there, however, temperatures can only be measured with great effort using the previously known means.
  • the invention has for its object to design an internal combustion engine of the type mentioned in such a way that optimal control and regulation can be carried out with as little effort as possible.
  • the evaluation electronics working with the electrical resistance of the glow plug as an input signal is designed to determine the temperature in the combustion chamber of the internal combustion engine which fluctuates periodically with the ignition frequency and / or operating data of the internal combustion engine which can be derived from the temperature in the combustion chamber.
  • the glow plug which is normally required in auto-ignition internal combustion engines to start the internal combustion engine, is used as a temperature sensor, since it changes its electrical resistance as a function of the temperature in the combustion chamber. This allows the temperature in the combustion chamber to be determined without the need for an additional temperature sensor. Thanks to the invention practically all temperature-dependent effects within the internal combustion engine can be observed and measured.
  • the average temperature of each cylinder can be determined via the resistance of the respective glow plug. This makes it easy to detect combustion irregularities in individual cylinders.
  • the ignition timing is also easy to determine because the ignition causes the temperature of the glow plug to rise due to the burning mixture.
  • a mixture that is too rich or too lean can also be determined via the temperature, because depending on its composition it cools the glow plug more or less when it flows into the combustion chamber.
  • the evaluation electronics can replace a speed sensor if, in a development of the invention, it is designed to determine the speed of the internal combustion engine based on the periodic temperature fluctuations of the glow plug.
  • the resistance measuring device of the glow plug could be a measuring value transmitter for various display instruments, for example a thermometer or a speed display.
  • the resistance measuring device as a measuring value transmitter for an automatic control circuit by the evaluation electronics having at least one actuator for controlling or regulating the internal combustion engine.
  • the actuator can control very different influencing variables, for example the coolant supply.
  • the actuator is designed to control a speed controller of the internal combustion engine.
  • a particularly advantageous engine management system results if the actuator is designed to control the mixture setting of the internal combustion engine.
  • the ignition point of a self-igniting internal combustion engine can be brought forward if the actuator is designed for the speed-dependent supply of heating current to the glow plug of the internal combustion engine. In such an internal combustion engine, ignition is initiated by periodically heating up the glow plug. This results in a further possibility of influencing the work of the internal combustion engine.
  • the invention permits numerous embodiments. To further clarify its basic principle, one of them is shown very schematically in the drawing and is described below.
  • the drawing shows an average of the upper area of a four-stroke self-igniting internal combustion engine, such as that used for model aircraft.
  • the internal combustion engine has in a cylinder 1 above a piston 2 a combustion chamber 3 into which an inlet duct 4 leads, which is controlled by means of an inlet valve 5.
  • An outlet channel 7 controlled by an exhaust valve 6 leads away from the combustion chamber 3.
  • the fuel is not injected, but is instead introduced into the inlet duct 4 by means of a carburetor 8.
  • a conventional throttle valve 9 is connected upstream of the carburetor 8.
  • a glow plug 10 which is required anyway for starting the internal combustion engine and leads into the combustion chamber 3, simultaneously serves as a sensor for monitoring the internal combustion engine.
  • a voltage source 11 Glow plug 10 leading line 12 an electrical resistance measuring device 13 switched. This measures the current flow through line 12. Since this is directly dependent on the electrical resistance of glow plug 10, which changes with the temperature of glow plug 10, the resistance measuring device provides information about the temperature of the glow plug.
  • evaluation electronics 14 Downstream of the resistance measuring device is evaluation electronics 14, which take into account in particular the fluctuations in the electrical resistance. For example, it can control a display instrument 15, which is, for example, a tachometer. It is also possible for the evaluation electronics 14 to compare the value measured by the resistance measuring device 13 with a setpoint from the setpoint generator 16 and to actuate an actuator immediately afterwards, for example the throttle valve 9.
  • the setpoint generator 16 is the receiving system which receives its control commands from the remote control transmitter .
