    Abstract: The invention provides a combustion engine comprising at least one combustion chamber, preferably several combustion chambers (1), wherein to each combustion chamber a piston (2) moving within a cylinder (3), a cylinder head (4) comprising at least one admission valve (5), at least one outlet valve (6), at least one spark plug (7) an intake port (13) and a throttle (8) controlling the engine load, is assigned. The combustion chamber (1) comprises a secondary injector means (14) for injecting a secondary fuel directly into the combustion chamber (1) in the direction of the spark plug (7) and secondary fuel supply means (15) for supplying a gas as a secondary fuel to said secondary injector means (14). Supply means (16) for compressed air and mixture means for providing a mixture of air and gas fuel to said secondary injector means (14), facilitating the stoichiometric air-to-fuel ratio to be held at λ=1.
