Internal Combustion Engine Having a Splitted Fuel Admission and a Respective Combustion Process

摘要

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.

1. Combustion engine comprising at least one combustion chamber, wherein to each combustion chamber a piston moving within a cylinder, a cylinder head comprising at least one admission valve, at least one outlet valve, at least one spark plug, an intake port with a primary fuel injector or a carburettor and a throttle controlling the engine toad, is assigned, wherein said combustion chamber comprises a secondary injector means for injecting a secondary fuel directly into the combustion chamber and secondary fuel supply means for supplying a gas as a secondary fuel to said secondary injector means,
characterized in that said secondary injector means for injecting a secondary fuel directly into the combustion chamber are arranged so that said secondary fuel is injected in the direction of said spark plug; said combustion engine further comprises supply means or pressure air and mixture means for providing a mixture of air and gas fuel to said secondary injector means said at least one of
control means for controlling the penetration length of the mixture injected by said secondary injector means, by controlling the injection pressure of the mixture injected by said secondary injector meansadjusting means for adjusting the penetration length of the mixture injected by said secondary injector means, by adjusting the injection pressure of the mixture injected by said secondary injector means.
