  • ignition systems for internal combustion engines which supply the necessary for triggering the combustion of a fuel-air mixture in a combustion chamber of the engine initial energy based on high-voltage induced sparks.
  • Ignition devices for internal combustion engines are also known from the prior art, in which the initial energy required for igniting the explosion of the fuel-air mixture is supplied by means of high-frequency energy waves, in particular microwaves.
  • microwave ignition Due to ever stricter legal standards for exhaust emissions and the increasing demand for lower fuel consumption of engines, The improvement of the efficiency of internal combustion engines is an important aspect in engine development. Achieving these goals is only possible with the use of microwave ignition, which significantly increases the spatial extent, the energy released and the duration of the ignition compared with the conventional spark plug so that a more homogeneous and complete combustion is possible.

  • a microwave source for example, a magnetron, klystron, gyrotron, a traveling wave tube or the like is provided. These require a complex pulse high-voltage power supply to convert the usual on-board vehicle voltage of 12 or 24 V in the operating voltage for the microwave source.

  • the ignition power of the microwave pulse ignition generator according to the invention is dependent on the number of microwave sources used and on the strength of the pulsed supply voltage which provides the microwave control for the operation of the microwave sources.
  • the proposed waveguide coupling section allows merging, ie, bundling of the respective microwaves emanating from the microwave sources without significant loss of power.
  • a large and heavy microwave source can be easily replaced by a number of smaller microwave sources, wherein the ignition performance of the microwave pulse ignition generator advantageously remains unchanged or can be increased.
  • the size and number of the smaller microwave sources can be selected and arranged relative to one another in such a way that the overall size and the total weight of the microwave pulse ignition generator can be significantly reduced in comparison with a single strong microwave source.
  • smaller and thus less radiation microwave sources usually require a reduced operating voltage, so that the pulse generator control can be performed correspondingly weaker, lighter and thus smaller.
  • the two or more microwave sources of the microwave pulse ignition generator according to the invention are preferably connected directly to the hollow line coupling section, from which the microwave discharge leads to the combustion chamber, wherein the microwave feed lines can run in a straight line and / or bent.
  • the invention also includes that with a larger number of microwave sources used, these are guided indirectly to the hollow line coupling section connected to the combustion chamber, i. the microwave radiation from at least two of the provided microwave sources upstream of this hollow duct coupling section, which has the microwave discharge leading to the combustion chamber, brought together via at least one further upstream waveguide coupling section and only then connected to the waveguide coupling section having the microwave derivative.

  • the offset is favorably chosen such that the microwaves from the various microwave feed lines after entering the waveguide coupling section do not or as little as possible mutually influence each other, resulting in a reduction of the intensity of the respective microwave radiation.
  • the offset is formed such that in the waveguide coupling section results in an amplification of the intensity of the microwave radiation, which is derived by the microwave derivative.

  • a phase shift of typically 360 ° after passing through the microwave inlets is provided in the waveguide coupling section.
  • This can be technically particularly simple and inexpensive to achieve, since in the pulse generator control no frequency modulator for the modulation of microwaves is necessary.
