Numerical Simulation of Ignition of Premixed Air/Fuel Mixtures by Microwave Streamer Discharge [PDF]
IEEE Transactions on Plasma Science, 2019 A subcritical microwave streamer discharge is used to initiate ignition of premixed air/fuel mixture. The streamer is arising on the internal surface of the dielectric tube using a passive vibrator in a single-pulse regime at atmospheric pressure and temperature. The propagation speed of the combustion front in the quartz cylindrical tube filled by the

Air fuel ratio control for a lean mixture combustion.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1986 If a gasoline engine can be run with a lean air-fuel mixture, a considerable improvement is expected in fuel consumption and in exhaust emissions. Especially in the case of automobile use, this effect is remarkable because of a peculiarity in the high frequency usage of engines operating under a partial load.

Hydrodynamic effects induced by nanosecond sparks in air and air/fuel mixtures [PDF]
55th AIAA Aerospace Sciences Meeting, 2017 It was found that short and intense energy release in nanosecond sparks can induce hydrodynamic motion of the gas over a long distance of the order of centimeter. The gas motion induces the transport of active species produced by plasma into the surrounding space.
