Abstract:
A method of igniting a mixture of oxidant and fuel in a combustion chamber of a combustion engine using a spark plug arranged so that it protrudes into the combustion chamber of the engine. The method includes powering the spark plug using a first alternating electrical signal of a frequency higher than 1 MHz, and second powering the spark plug using a second alternating electrical signal of a frequency higher than 1 MHz, the second power taking place after the first powering following a time delay.
