<p>Spark plug (1) comprising at least two insulated electrodes (5), and (6), an earthed electrode (7) and a chamber (4) so arranged with respect to one another that when a voltage is applied arcs are struck in series between electrodes (7) and (6) and (6) and (5) to provide a continuous plasma jet expelled from the chamber (4) at low energies (< 100mJ) and which can be used for combustion of a lean air/fuel mixture. </p> |
