“…This has the effect of lengthening the distance between the inner and outer electrodes and better matching of the impedance of the ignitor and spark source. A ‘soup of ions’ is formed by an arc discharge within this cavity from which it is expelled by a high-pressure gradient created between the medium in the cavity and the unburned gas [ 2 , 5 ]. The advantages of FDI igniters are found to be the higher velocities and reaction rates and the increased production of radicals, which are proven to chemically augment the combustion and stability of the system.…”

“…There is a small difference between plasma jet igniters (PJIs) and FDIs. PJIs usually feed continuous gas into the cavity of the igniter (continuous plasma jet) [ 5 , 6 ] in order to enhance radical production. FDIs, on the other hand, create a plasma discharge with whatever exists at the cavity of the igniter during the operation of the engine [ 3 ].…”

“…De esta forma, se han llevado a cabo investigaciones en torno a la posibilidad de incorporar combustibles alternativos en el ámbito de los motores de combustión interna alternativos. Por citar algunos ejemplos en este punto, se han desarrollado distintos ensayos con gas natural y metano [7][8][9][10][11][12][13][14][15][16][17][18], etanol [19][20][21][22][23], metanol [24][25][26][27], propano [28][29][30][31][32][33] y con hidrógeno [34][35][36][37][38][39][40][41]. Este último, el hidrógeno, ha suscitado el interés de múltiples grupos de investigación en su afán por conseguir un combustible que, al no contener átomos de carbono en su molécula, mostraría unas emisiones nulas en cuanto a CO2 se refiere, explotando al mismo tiempo su condición de vector energético [3].…”
