Injection system for compression-ignited diesel engines

摘要

The fuel injection system has a first injection nozzle that is arranged centrally above a combustion chamber (117). A second controllable injector nozzle (101) is arranged in an upper wall or confinement region of the combustion chamber. The homogenous air-fuel mixture is formed in the combustion chamber below a self-ignition limit by the second injector nozzle. The amount of fuel is introduced as ignition injection by third injection nozzle (107) according to the state change of the temperature and pressure within the cylinder.
