Abstract (en)

[origin: DE102005056520A1] Method involves a fuel-injection unit (25) and a laser ignition-unit (26). During compression cycle of the internal combustion engine (20), fuel is injected into combustion chamber (29) by fuel-injection unit in such a way that an ignitable, round, flat mixed region (28) of fuel and air forms on 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. Ignition then takes place within the flat round mixed region by means of the laser-ignition unit. An independent claim is included for the internal combustion engine.
