| 摘要 |
The invention relates to a method for operating an internal combustion engine (20) comprising a fuel-injection unit (25) and a laser ignition-unit (26). According to the invention, during a compression cycle of the internal combustion engine, fuel is injected into the combustion chamber (29) by means of the fuel-injection unit (25) in such a way that an ignitable, round, flat mixed region (28) of fuel and air forms on a plunger (21) and a predetermined period elapses between the end of the fuel injection and the start of ignition in order to form the round flat mixed region (28). Ignition then takes place within the flat round mixed region (28) by means of the laser-ignition unit (26).
