PCT No. PCT/EP92/00977 Sec. 371 Date May 5, 1995 Sec. 102(e) Date May 5, 1995 PCT Filed Mar. 5, 1992 PCT Pub. No. WO92/20912 PCT Pub. Date Nov. 26, 1992.A second spark is triggered, after a first ignition spark. The initiation overvoltage of the second spark is detected. The overvoltage and the occurrence or the non-occurrence of a failure of ignition of the air/fuel mixture prior to the second spark is deduced, according to whether the overvoltage is greater or less than a predetermined threshold voltage. Application to the protection of a chamber containing an oxidation, reduction catalyst for the exhaust gases of the engine.
