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

Multi-point ignition of air/fuel mixture by the initiated subcritical streamer discharge [PDF]
Acta Astronautica, 2022 Abstract An experimental study of ignition and combustion of a propane/air mixture is carried out, and the efficiency of two ignition systems is compared. The first one is the traditional technology with conventional spark plugs, and the second one is a system with microwave initiated streamer discharges.

Auto-Ignition and Flame Stabilization of Hydrogen / Natural Gas / Nitrogen Jets in a Vitiated Cross-Flow at Elevated Pressure [PDF]
, 2013 The influence of natural gas (NG) on the auto-ignition behavior of hydrogen (H2)/nitrogen (N2) fuel jets injected into a vitiated cross-flow was studied at conditions relevant for practical combustion systems (p = 15 bar, Tcross-flow = 1173 K).

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.
