  • Arrangement and method for efficient combustion of fuel in a combustion engine
    Patent number: 8701627
    Abstract: In a combustion space of a combustion engine, an inlet valve to supplies a gaseous medium which contains oxygen to the combustion space. A movable piston to compress the gaseous medium in the combustion spaces. An injector injects fuel in the combustion space in a jet which comprises a multiplicity of small fuel drops. The injector injects fuel in the combustion space at such a high initial velocity that the fuel injected in the jet mixes with the gaseous medium to form a substantially homogeneous mixture before the mixture has been decelerated to a velocity at which the fuel ignites and burns. Devices may cool the gaseous medium and the fuel before entry into the combustion space.
