Extending Lean Operating Limit and Reducing Emissions of Methane Spark-Ignited Engines Using a Microwave-Assisted Spark Plug

open access: yesJournal of Combustion, 2012
A microwave-assisted spark plug was used to extend the lean operating limit (lean limit) and reduce emissions of an engine burning methane-air. In-cylinder pressure data were collected at normalized air-fuel ratios of λ=1.46, λ=1.51, λ=1.57, λ=1.68, and ...

Observations on the spark discharge [PDF]

open access: yesProceedings of the Royal Society of London, 1890
Abstract The subject of dust-figures produced by electrical discharge has received much attention at various times. In the following notes I have refrained, to the best of my knowledge, from going over old ground. The subject has been reviewed in Lehmann’s recently published ‘Molekularphysik.’ It is a sufficient substitute for the ...

A Simple Model of Spark Gap Discharge Phase [PDF]

open access: yesEngineering and Technology Journal, 2013
A simple computational model is established to simulate the spark gap discharge phase. The proposed computational approach is based on Rompe- Weizel model for the resistive phase of the spark discharge where the plasma resistance decreases dramatically ...

The emission of light from spark discharges [PDF]

open access: yesProceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1946
Abstract The investigation is concerned with the transitory effects occurring in spark channels, after the discharge gap has been' bridged completely by a streamer. Observations have been made for various gases, in particular for hydrogen and argon, at pressures of the order of 1 atm.

A Novel Way to Enhance the Spark Plasma-Assisted Ignition for an Aero-Engine Under Low Pressure

open access: yesApplied Sciences, 2018
Finding a new ignition strategy for ignition enhancement in a lean-burn combustor has always been the biggest challenge for high-altitude, long-endurance unmanned aerial vehicles (UAVs).
