An ignition system (10) comprises a spark plug (12) having a first end (14) defining a spark gap (16) between a first electrode (18) and a second electrode (20). A transformer (46) comprises a primary winding 44 and a secondary winding (50) also forms part of the system. The secondary winding is connected in a secondary circuit to the first electrode 18 and the secondary winding has a resistance of less than 1KΩ and an inductance of less than 0.25 H. A drive circuit (26) is connected to the primary winding.
1. A method of monitoring at least one parameter associated with a gaseous substance in a chamber, the method comprising the steps of: utilizing a first electrode and a second electrode, at least one of which is exposed to the substance and which collectively define a gap and form an electrode capacitor, to generate a corona at the at least one electrode without creating a spark over the gap;causing the corona to change an electrical parameter in a region of the at least one electrode which is indicative of the at least one gas parameter;causing a signal...
