  válasz Qru #222689 üzenetére

  Ebben GDI és MPI van, kis terhelésen és fordulaton a szívócső-, padlógázon a direktbefecskendezés megy, köztes állapotban vegyesen üzemelnek. (asszem jól írtam)

  Szerk: Nagyjából jól írtam, ezek szerint nem üzemelnek vegyesen.

  Operating Modes
  The control concept for executing the operation modes has been standardized using a mapping. The mapping determines if and when the engine can be operated SRE mode and when it can operate in high pressure mode. It distinguishes between the following operating modes:
  - Single injection SRE
  - single high-pressure injection
  - Double high-pressure injection
  - Triple high-pressure injection
  The engine switches between different operating modes depending on the temperature, the load and the engine speed.

  Starting the engine
  In cold engine and a temperature of the coolant below 45 ° C and at each engine start, a triple direct injection takes place during the compression stroke through the high pressure injection system.

  temperature and catalyst heating climb
  During this phase, a double direct injection takes place during the intake and compression time. The ignition point is shifted slightly towards the "delay". intake manifold flaps are closed.

  Motor operating in partial load range
  When the motor temperature exceeds 45 ° C and the engine operates in the partial load range, there SRE switching mode. •
  Intake manifold flaps remain largely closed.

  Motor operating in full load range
  Because of the high power requirement, the system returns to high pressure mode. A double direct injection takes place during the intake and compression time.

  degraded mode operation
  In case of failure of one of the two injection systems, the engine is driven only with the remaining system by the engine computer. The vehicle thus remains operational. •
  The red light engine in the instrument cluster lights up.
