ABSTRACT:
A diesel engine is started by plural ignition plugs, each installed in a swirl chamber of a corresponding cylinder. Each ignition plug includes (a) an elongated center electrode, (b) a fuel-absorbent electrical insulator that encapsulates the center electrode so as to allow only one end of the center electrode to protrude, and (c) a plurality of elongated grounding electrodes arranged symmetrically around said insulating member to define a discharge path in conjunction with the protruding end of the center electrode. The discharge path includes part of the surface of the insulating member and an air gap between free ends of the grounding electrodes and opposing surfaces of the insulating member.
