Definitions

  • the invention relates to a method for control the fuel injection at a fast running according to direct injection diesel engine the preamble of claim 1.
  • the object of the present invention is to achieve this based on a method for controlling fuel injection with multi-cylinder high-speed direct injecting diesel engines with solenoid valves cylinder-selectively controlled cam driven Injection pumps, such as B. a distributor injection pump, to create a drop in fuel injection pressure below a predetermined tolerable value too is avoided at low speed and load and so too in this operating area through good fuel conditioning in the combustion chamber a good efficiency and cheap Emission values can be achieved.
  • the invention solves this problem with the features of claim 1.
  • the sub-claims have advantageous Developments of the invention to the subject.
  • the triggering time of the injection valve at least one cylinder set to zero.
  • the control time is in a manner known per se of the other injectors raised so that whose fuel injection quantity increases by an amount which a constant torque of the internal combustion engine backs up.
  • Fuel injection quantity is now sufficient one for fuel processing in the combustion chamber build up sufficiently high injection pressure.
  • the injector size can be selected almost optimally, the compromise between optimal performance and low emissions is defused.
  • the invention is relatively simple by itself Modification of the engine control software can be implemented.
  • Fuel temperature, coolant temperature or oil temperature and air mass as well as the position the accelerator pedal (e.g. in a motor vehicle drive), current engine torque and driving dynamics (i.e. pedal travel depending on the time) can be particularly low dynamic or in steady operating conditions the number of the internal combustion engine depending on the map required injections per cylinder applied become.
