Abstract (en)
[origin: WO2006106267A1] The invention concerns an internal combustion engine radio frequency spark plug (1) comprising two plasma-generating electrodes (2, 3) separated by an insulator (4) which constitute respectively an outer shell (3) enclosing the insulator and a central electrode (2) housed in a central bore of the insulator. The invention is characterized in that it has a deep opening (6) over the entire circumference of the shell (3), forming a heat-exchanging chamber inside the spark plug shell (1), opening outwards.
