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).

摘要： A method for operating an internal combustion engine, injects fuel directly into a combustion chamber as a main injection, a postinjection and optionally also as a preinjection. An injection nozzle with a plurality of injection bores effects the preinjection and the postinjection preferably which is carried out cyclically. To minimize wetting of the combustion chamber walls, during the postinjection the partial quantities of fuel and a lift of the nozzle needle of the injection nozzle are set so that, for each partial quantity of the postinjection injected into the combustion chamber, the reach of the respective fuel jet in the combustion chamber is limited and the reach is less than the distance to a combustion chamber boundary.

摘要： The method involves partially guiding fuel along a cavity bottom contour between a compression projection and a cavity edge, when the fuel impinges on a piston cavity (4) that is arranged in a piston. The fuel parts guided along a cavity bottom contour are partially separated from a cavity bottom surface or deviated by inclination change of the cavity bottom or by a convex region in the cavity bottom. An independent claim is also included for an internal combustion engine for implementing the method for operating the internal combustion engine.

摘要： A method is provided for operating an internal combustion piston engine, in which fuel is injected directly into a working chamber in the form of a pre-injection and main injection by means of an injection nozzle with a plurality of injection holes. The pre-injection takes place in a clocked manner. In order to minimize the moistening of the walls of the combustion chamber, a higher fuel pressure prevails in an injection device during the main injection than during the pre-injection. Furthermore, optimum homogenization of the pre-injected quantity of fuel is obtained by restricting the range of the injected fuel jets while simultaneously maximizing the atomization of the fuel particles and reinforcing the disintegration of the fuel jets during the clocked pre-injection.

摘要： The operating cycle is for a direct injection internal combustion piston engine, in which fuel is injected at high pressure, into the working volume (8), centrally with respect to the piston (7) crown trough (6). The fuel is injected shortly before crankshaft (2) top dead center (BTDC) (12), to form a heterogeneous mixture with defined layering, achieved as for diesel engines. The system includes an electronic calculator (16) and involves careful adjustment of air movement in the cylinder (9), injection pressure and timing. Alternatively, fuel may be injected much earlier, at a crank angle of 180-20 degrees BTDC, so that a combustible, homogeneous mixture is formed to enable uniform combustion in the load region. Fuel is injected at a lower pressure in the central part of the load region, to enable homogeneous mixture formation during the phase occurring between 180 and 20 degrees BTDC. The remainder of the fuel charge is injected, at a higher pressure, in the phase around TDC.

摘要： The invention relates to a method for injecting fuel into the combustion chamber of an internal combustion engine, especially for injecting diesel oil, via an injection nozzle. According to said method, a plurality of rows of punched holes are provided that are arranged one on top of the other and/or one behind the other in the direction of the injection nozzle. In the partial load range pre-injection jets (14) with different injection directions and/or angles are injected into the combustion chamber via at least one first row of pre-injection openings (8, 9) in such a manner that an at least substantially homogeneous mixture of air and fuel is produced. In the approximate full load range main jets (13) are injected into the combustion chamber by means of additional main injection openings (10) that are distributed across the circumference. The fuel injection is guided in such a manner that the main jets (13) interact with at least two pre-injection openings (8, 9) that are allocated to one main injection opening (10) and that are at least mainly integrated into the main jet (13) that is produced upstream of the allocated main injection opening (10) to give a jet cluster that is distributed across the circumference.
