Abstract:
1. An arrangement for a combustion engine, wherein the combustion engine comprises a combustion space, a piston which is arranged for movement in the combustion space and is operable to compress a fuel mixture in the combustion space for causing self-ignition of the fuel mixture in the combustion space the arrangement comprises a first fuel delivery arrangement operable to supply a first partial quantity of the fuel mixture to the combustion space, a second fuel delivery arrangement operable to supply a second partial quantity of the fuel mixture to the combustion space, wherein the second partial quantity of the fuel mixture is at a different fuel concentration than the first partial quantity of the fuel mixture, the fuel delivery arrangement operable to supply the partial quantities of the fuel mixture in such a way as to create at least one region in the combustion space which is at a higher fuel concentration than other regions in the combustion space and in which self-ignition of the fuel mixture is intended to start.
