Symposium (International) on Combustion, 1988
An experimental investigation was carried out to determine the minimum spark ignition energy of monodisperse tetraline aerosols in a laminar gas flow. Results, presented in terms of spark ignition frequency, and for droplet sizes between 6.7 μm and 40 μm, showed: a relatively weak dependence on spark duration, an optimum spark gap width between 3 and 4

Calorimetry of Ignition Sparks
SAE Technical Paper Series, 1988<div class="htmlview paragraph">The thermal energy transferred to noncombusting gases by a spark at pressures from 1 to 7 atmospheres was measured using a pressure-rise calorimeter. The energy transfer efficiency (from electrical to thermal energy) was determined for conventional coil ignition systems, a plasma jet ignitor, and an ultra-short ...

This chapter considers how the combustion process is initiated and constrained in spark ignition engines. The air/fuel mixture has to be close to stoichiometric (chemically correct) for satisfactory spark ignition and flame propagation. The equivalence ratio or mixture strength of the air/fuel mixture also affects pollutant emissions, as discussed in ...

Spark Spectroscopy for Spark Ignition Engine Diagnostics
SAE Technical Paper Series, 1995<div class="htmlview paragraph">The light emissions from a spark discharge were observed by inserting a fibre optic cable through the centre electrode of a spark plug, to investigate the possibility of determining the fuel-air ratio in the spark gap at ignition with spectroscopy.</div> <div class="htmlview paragraph">The total ...

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">A new “Traveling Spark Ignition” (TSI) system which, aided by a Lorentz force, propels a large plasma into the chamber of internal combustion engines, has been developed and tested on a single cylinder 4-stroke engine run on natural gas. Engine test scenarios included: conventional spark plugs with high energy CDI (

The Prediction of Auto Ignition in a Spark-Ignited Engine
SAE Technical Paper Series, 1984<div class="htmlview paragraph">A constant volume combustion simulation has been used to compute the ignition delays of pure fuels and binary fuel mixtures in air. Minima in the ignition delays were predicted by a comprehensive chemical kinetic mechanism for binary fuel mixtures with methane.

Modern ignition systems may be conveniently divided into TWO types. These are: The first system, having contact breaker points, may be as shown opposite. To improve cold start performance this system may have included into it a The second system may use one of many methods of allowing transistors to switch-off the primary current (this being the ...

In the context of nonshock initiation of secondary explosives, electric sparks and lasers represent sources of external power that may stimulate exothermic reaction in energetic materials, and generate enough heat and reaction product gases to ignite a propagating combustion reaction.
