Abstract (en)

[origin: WO2010109137A1] The invention relates to a method of igniting a mixture of oxidant and fuel (1) in a combustion chamber (2) of a combustion engine using a spark plug (3) arranged so that it protrudes into the combustion chamber of the engine (3), said method including a first step of powering the spark plug using a first alternating electrical signal of a frequency higher than 1 MHz (4). The method also includes a second step of powering the spark plug using a second alternating electrical signal of a frequency higher than 1 MHz (5), said second step taking place after the first step and following a time delay (6).
