“…An orifice at the cavity exit is often used to pressurize the ionization and combustion products and cause a hot jet of reactive species to issue into the combustion chamber. Open cavity designs are also common (Asik et al, 1977;Edwards et al, 1983;Kupe et al, 1987). Plasma jet ignitors can effectively ignite a mixture outside the ignitor when there is not a combustible mixture in the cavity (Smy et al, 1985).…”

“…The ionized spark kernel is immediately moved away from the housing where it is created, to a location within the combustion chamber where the thermodynamic conditions are more favorable for rapid flame growth. Experiments performed applying plasma jet igniters to production and research engines [18][19][20][21][22] show the extensions of lean operation and the improvements in engine efficiency at all engine loads. Exhaust emission measurements show no differences for CO and HC emissions, while NOx levels are higher with the plasma jet systems due to faster combustion.…”

“…Ignition systemparameterscan be separated into two categories; those relating to the spark plug and those relatinl_ to the electrical energy supply system. Studiesrelated to the spark plug itself include investigationsof the effect of electrode material [1], diameter [2,3], and orientation [4]; as well as more drastic changesto the standardJ-gapdesign such as surface gap plugs [5,6] and plasma jet ignitors [7]. Numerous studieshave also been made of the effect of the rate and duration over which energy is delivered to the spark, in most cases relative to conventional J-gap plugs.…”

An experimental study of the effect of spark power on the growth rate of spark-ignited flame kernels was conducted in a turbulent flow system at 1 atm, 300 K conditions. All measurements were made with premixed, propane-air at a fuel/air equivalence ratio of 0.93, with 0%, 8% or 14% dilution. Two flow conditions were studied: a low turbulence intensity case with a mean velocity of 1.25 m/sec and a turbulence intensity of 0.33 m/sec, and a high turbulence intensity case with a mean velocity of 1.04 m/sec and a turbulence intensity of 0.88 m/sec. The growth of the spark-ignited flame kernel was recorded over a time interval from 83/lsec to 20 msec following the start of ignition using high speed laser shadowgraphy. In order to evaluate the effect of ignition spark power, tests were conducted with a long duration (-4 msec) inductive discharge ignition system with an average spark power of-14 watts and two short duration (- .-100 nsec) breakdown ignition systems with average spark powers of-6 x 104 and-6 x 105 watts. The results showed that increased spark power resulted in an increased growth rate, where the effect of short duration breakdown sparks was found to persist for times of the order of milliseconds. The effectiveness of increased spark power was found to be less at high turbulence and high dilution conditions. Increased spark power had a greater effect on the 0-5 mm burn time than on the 5-13 mm burn time, in part because of the effect of breakdown energy on the initial size of the flame kernel. And finally, when spark power was increased by shortening the spark duration while keeping the effective energy the same there was a significant increase in the misfire rate, however when the spark power was further increased by increasing the breakdown energy the misfire rate dropped to zero.
