DIESEL INTERNAL COMBUSTION ENGINE

摘要

The invention relates to an internal combustion engine comprising at least one cylinder (1) in which a combustion chamber (5) is defined between a piston (3) and a cylinder head (2), a fuel injector (6) arranged in the cylinder head (2), and a piston cavity (4) arranged in the piston (3). Fuel is injected into the combustion chamber (5) during a working cycle, by means of an injection nozzle (6a), in the form of a plurality of partial quantities as a pre-injection, main injection and/or secondary injection. When the fuel meets the piston cavity (4), it is guided at least partially along a cavity bottom contour (11) between a compression projection (10) and a cavity edge (15), and the fuel parts guided along the cavity bottom contour (11) are at least partially separated from a cavity bottom surface or deviated by means of a change (16) in the incline of the cavity bottom (14) or by a convex region (R2) in the cavity bottom (14).
