Definitions

  • the invention relates to the power supply of an electrically generated plasma for the ignition of fuel-air mixtures, wherein for the initiation of the plasma, the electrical breakdown, a high voltage at high impedance at the discharge gap between usually two electrodes is neces sary.
  • the ignition of lean ( ⁇ > 1) directly injected and layer-charged air-fuel mixtures makes high demands on the ignition system.
  • a large as far as possible projecting into the combustion chamber ignition volume is required, but also a high ignition energy to ignite the flame retardant mixtures can.
  • An electrical supply that is designed to achieve a high voltage for the electrical breakdown is usually unsuitable to effectively supply the plasma during the further gas discharge course. The reason for this is the substantial impedance change after the formation of a conductive plasma channel at an ignition device.
  • the ignition should usually be carried out under pressures between 5 to 50 bar.
  • the characteristic ambient pressure at the spark gap is to be considered.
  • the specified ignition point must be reached at every pressure with the same tolerance of a few ⁇ s.
  • Ignition point is also very variable.
  • the operating room / combustion chamber is not oxygen-free and the components are exposed to strong corrosion.
  • the choice of materials used is thus severely limited.
  • Existing fluid flows up to 100 m / s must not interfere with the initiation of the plasma nor the further supply of the plasma channel with energy.
  • the plasma must not go out for a required burning time.
  • the ignition is usually carried out serially or periodically with a frequency of, for example, 8-70 Hz. The requirement for the ignition is to ignite non-ionized gas, in each case in the cold state.
  • Conventional ignition systems with ignition coil and spark plug represent, among other things, a compromise between spark duration, high voltage and electrode burn-up. After the breakthrough phase in the arc discharge, they supply the energy still stored in the system. This process is typically after one ⁇ s completed. In the following glow discharge, the energy stored in an ignition coil is converted in the plasma channel. The temperature of the plasma decreases in this phase. The duration depends on electrical parameters and can not be actively influenced in a given system. A to be adapted due to variable operating conditions power supply is not feasible. Conventional ignition systems can not be used for high pressures because, due to the material, the electrical feedthrough does not meet the voltage requirements that increase with pressure.
