Definitions

  • the invention relates to a method for injecting fuel into the Combustion chamber of a cylinder of a reciprocating piston internal combustion engine Diesel design in part-load operation according to the upper clause of claim 1.
  • EP 0 775 821 describes a method for injecting Fuel in the combustion chamber of a slow-moving cylinder Two-stroke reciprocating internal combustion engine of the diesel type known.
  • the Fuel is injected into the combustion chamber with two to four fuel injectors injected, with the injectors constantly over the entire load range are in operation.
  • the for one Work cycle determined amount of fuel using only one injector injected, and in the next work cycle the amount of fuel the second injector injected so that through each injector alternately, the required during one work cycle Amount of fuel is injected.
  • a disadvantage of this injection method is the fact that in particular incomplete combustion occurs during partial load operation in the combustion chamber, so that the combustion fumes have a high proportion of visible smoke, in English called "visible smoke".
  • the object of the present invention is the reciprocating piston internal combustion engine to operate the diesel type in such a way that it is a more advantageous Has running behavior.
  • the object is achieved in particular with a method for injection of fuel in the combustion chamber of a cylinder one Reciprocating internal combustion engine of the diesel type at partial load operation, whereby at least two injection nozzles are assigned to each combustion chamber by the Fuel is injected so alternately that during at least two consecutive work cycles with at least one no fuel is injected into the injectors, and that after that during at least two consecutive work cycles from the no fuel is injected into another injector.
  • This method allows a higher zone in the combustion chamber Generate temperature.
  • the Fuel for at least three minutes, preferably between 10 and 30 minutes, from the same injector or asymmetrically injected from the same injectors to thereby generate a higher temperature in the combustion zone in the long term.
  • An advantage of this method is that the number is thermal Load changes, compared to that in EP 0 775 821 disclosed method, is reduced, which is favorable to the Material fatigue.
  • the locally higher temperature in and around the Combustion zone reduces visible smoke.
  • the Injecting the fuel with only one nozzle has the advantage that the Fuel is injected through this nozzle for a longer period of time, which causes a stable, reproducible injection results.
  • a constant change between the individual nozzle during injection has the disadvantage a higher number of thermal load changes.
  • the fuel is preferably injected through a single nozzle.
  • the partial load operation leads to a lower overall temperature level in the Combustion chamber and on the combustion chamber components. That's why they're through the uneven temperature distribution caused higher voltages of the combustion chamber components so that none on the combustion chamber components excessive or critical tensions occur. Even the appearance of High temperature corrosion due to a locally higher combustion chamber temperature excluded due to the lower overall temperature level.
  • the method according to the invention is particularly suitable for very deep ones Part load operations of less than 15% of full load are suitable, especially for Partial loads between 1% and 3% of full load.
  • the inventive method allows an environmentally friendly Combustion in part-load operation, and has the decisive advantage that the optically disturbing, gray or black exhaust gas clouds are avoided become. This is particularly advantageous for marine diesel engines.
  • the method according to the invention is suitable for the operation of stationary and movable two-stroke and four-stroke diesel engines, especially for Four-stroke diesel engines with a cylinder bore of more than 150 mm or for two-stroke diesel engines with a cylinder bore of more than 300 mm in diameter.
  • Switching an injector on and off when switching to one of the three operating modes mentioned advantageously take place with one Switching function that has a hysteresis.
  • first and second partial load ranges that, starting from the first partial load range, with a partial load of 12.5% of the full load in the operating mode according to the second partial load range is switched, whereas, starting from the second part-load range a partial load of 17.5% of full load in the operating mode according to the first Partial load range is switched.
  • Switching from one operating mode to another can also be done, for example in such a way that a time control is used, so that after a certain time, for example 20 seconds after the lower or exceeding a predetermined threshold, to another Operating mode is switched. Switching from one to the other Operating mode can also be abrupt, so that with a larger one Change in load, for example 5%, immediately to another Operating mode is switched.
  • one cycle is used to operate the Reciprocating engine understood process taking place, which among other things the actuation of the valves, the injection of fuel, the Burn, and the emission of the combustion exhaust gases includes.
  • a 2-cycle machine is usually a work cycle after one Revolution completed, whereas the working cycle for a 4-stroke machine is completed after two turns.
  • Fig. 1 shows a two-stroke diesel engine 1 with a plurality of cylinders 11 and Piston 10, in which the interaction between the crankshaft 2, the Fuel supply and the movement of the exhaust valve 13 electronically is controlled.
  • a high pressure pump 4 With a high pressure pump 4, the fuel on the Pipeline 6 and the accumulator 5 of the injection nozzle 12 are supplied.
  • On hydraulic system comprising the pressure pump 7, the pipeline 9 and the accumulator 8 allows the position of the exhaust valve 13 to be actuated.
  • the longitudinally flushed two-stroke diesel engine 1 has a centrally arranged one Exhaust valve 13 and a plurality of peripherally on the cylinder cover arranged injectors 12. Usually such a Two-stroke diesel engine 1 has two to four fuel injectors 12.
  • FIG. 2a schematically shows the combustion chamber of the cylinder 11 with three peripherals and regularly spaced injection nozzles 12a, 12b, 12c.
  • This process example shows a partial load operation with one each single active injector 12a. Via the injection nozzle 12a Fuel 14a is injected, while injectors 12b and 12c in shown time no fuel 14a is injected. While at least two consecutive work cycles will only be done through the Injector 12a fuel 14a injected to thereafter during at least two consecutive working cycles of fuel 14a only via the injector 12b and then for at least another two successive duty cycles only through the injector 12c inject. In a particularly advantageous method, during much more than two successive work cycles, for example, for 10 to 30 minutes, fuel from a single one Injector 12a supplied.
  • 2b shows a process example in partial load operation with two each simultaneously active injection nozzles 12a, 12b.
  • Analogous to 2a is also the fuel 14a, 14b during at least two consecutive work cycles the injectors 12a, 12b are fed, then for at least two successive working cycles only via the injection nozzles 12b, 12c, and then via the two injection nozzles 12c, 12a. This method is repeated continuously.
  • the fuel 14a, 14b for 5 to 60 minutes, in particular 10 to 30 minutes through the same two injectors 12a, 12b inject before another pair of injectors 12b, 12c, is changed.
  • FIGS. 2a and 2b show just two examples of a variety of ways, like in a two-stroke or four-stroke diesel engine, each with two to four fuel injection nozzles 12 per cylinder 11 by opening only part of the existing nozzles Fuel 14a, 14b can be injected asymmetrically to thereby a longer and more stable injection duration and a temporarily uneven Temperature distribution in the combustion chamber, or one Combustion zone with a higher temperature during part-load operation achieve.
  • the injection nozzles 12a, 12b, 12c are for dimensioned an operation at nominal load. For an advantageous spray behavior it is therefore advantageous to obtain the relatively low one at low partial loads Amount of fuel through a single injector 12a, 12b, 12c Feed the combustion chamber.
