Betterment of ecological parameters of a diesel engine using Brown‘s gas
Journal of Environmental Engineering and Landscape Management, 2013 Hydrogen could become an important element, allowing us to accumulate and transfer energy in a clean way. Hydrogen can be used in cars as a fuel additive which increases the combustion efficiency of the fuel-air mixture.

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.

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.

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.

Transient plasma ignition of quiescent and flowing air/fuel mixtures
IEEE Transactions on Plasma Science, 2005 Transient plasmas that exist during the formative phase of a pulse-ignited atmospheric pressure discharge were studied for application to ignition of quiescent and flowing fuel-air mixtures. Quiescent methane-air mixture ignition was studied as a function of equivalence ratio, and flowing ethane-air mixture was studied in a pulse detonation engine (PDE)
