The invention relates to a
detonation-wave-front high-
voltage electric
plasma gas
relay coupling ignition
detonation engine which is formed by a pre-
detonation burning
pipe (7), a high-
voltage ignition head c (8), a high-
voltage ignition head, a
plasma flow guide
pipe (10), an annular face magnetic pole plate (14), a
field coil (15), a detonation spraying
pipe (16), a current controller (17), a high-voltage ignition-oil injection control ECU (19), a fuel and air premixing chamber (22), an
air velocity transducer (25) and a
high pressure oil spraying pump (26). Through multi-stage high-voltage ignition and
plasma gas
discharge, after a tiny pulse detonation wave is subject to three-stage
relay coupling ignition, energy is amplified continuously, the best energy is achieved finally, the energy is sprayed out from a
fuel gas spraying opening (24), and generation of detonation is guaranteed. The detonation-wave-front high-voltage electric plasma gas
relay coupling ignition detonation engine has the beneficial effects that (1) the detonation, control and quick holding of the knock can be solved, and the pulse detonation wave can be gradually amplified; (2) atomization, jetting and
doping of
liquid fuel and an
oxidizing agent can be achieved; (3) stable pushing force can be generated,
low frequency to high-frequency continuous work can be achieved; and (4) pulse knock
engine power adjustment can be achieved.
