ABSTRACT:
A method and apparatus for operating an internal combustion engine in which in the event of erroneous fuel injection, combustion is maintained following the expansion stroke via a constantly hot spot in the combustion chamber, in such a way that erroneously introduced fuel is combusted, by reducing the oxygen content in the combustion chamber, such that no later than by the end of the compression stroke of the engine, a possible conversion of existing fuel and existing oxygen can no longer occur to any substantial extent, because of the heating of the contents of the combustion chamber toward the end of the compression stroke, thus preventing this malfunction from destroying the engine.
