Definitions

  • the invention relates to a controller for the fuel metering of an internal combustion engine according to the preamble of claim 1.
  • DE 44 35 419 A1 is a control system for describes the fuel metering of an internal combustion engine, where a hot start situation is then assumed when the temperature of the coolant of the internal combustion engine above a predetermined threshold temperature is the difference in the intake air temperature between the current value and a saved one previous value exceeds a predetermined size.
  • the Hot start situation is no longer considered a given, when the engine coolant temperature is below a second threshold temperature or if the internal combustion engine draws in a predetermined amount of air Has.
  • the object of the invention is a controller for the fuel metering of an internal combustion engine according to to form the preamble of claim 1, that a hot start situation under all operating conditions the internal combustion engine with little effort is reliably recognized.
  • the invention solves this problem with the characterizing Features of claim 1.
  • the subclaims have advantageous development of the invention to the subject.
  • the invention assumes that the main problem a hot start from vapor bubble formation runs out within the injector.
  • the capture of the Temperature at the injection valve via temperature sensors would, however, cause considerable effort in which there is an installation space for such a sensor and a signal line to the sensor should. It would also require sensor monitoring to check the functionality of the sensor to provide.
  • the response behavior the control for recognizing a hot start situation become.
  • the values of the current temperature on Injector depending on voltage and resistance on the electrical conductor of the opening device in a memory in the signal processing system be stored so that the temperature values in real time even with low computing power of the signal processing system be available.
  • the signal processing system can be advantageous Way through the already existing electronic Engine control unit to be formed.
  • the calculated resistance ⁇ is then converted to the current resistance ⁇ on Injector local temperature T determined (Box 5).
  • the current temperature T determined in this way is compared with a calibrated temperature value T K determined by experiment and stored in the signal processing system (box 6).
  • This temperature value T K represents the hot start limit to be observed for the present internal combustion engine. If this limit is reached or exceeded, there is a hot start condition (Box 7).
  • a hot start correction (box 8) for the injection signal is then generated (box 9).
  • other engine parameters can be adjusted with the hot start correction, such as: B. a correction of the air requirement, an increase in the idle speed or a correction of the ignition timing.
