Abstract (en)
[origin: FR2895024A1] The method involves determining loss and failure of combustion e.g. diesel combustion, in a combustion chamber of an engine by comparing a running average value of a predetermined variable of the engine with a predetermined threshold value. The running average value of the variable is modified when the failure of combustion is detected, where the variable depends on release of energy of a gas in the combustion chamber.
