A method of operating an air-compressing, self-igniting combustion engine for liquid fuels, in an arrangement that includes a combustion chamber depression in a piston for receiving injected fuel predominantly in the vicinity of the wall thereof and for receiving rotating combustion air at the time of fuel injection. Oxygen-containing fuel that is reluctant to ignite is injected through a first injection device into the combustion chamber depression; through a second injection device there is injected fuel that is willing to ignite, for instance oil fuel, gas oil or Diesel fuel, for initiating and/or maintaining the fuel combustion in the combustion chamber depression. Furthermore, the injection times of the fuel that is willing to ignite and the oxygen-containing fuel that is reluctant to ignite overlap each other. The first and second injection nozzles each are arranged with an injection pump and are rigidly coupled and have a common injection adjuster. Both injection nozzles are combined in a single-nozzle body. One injection nozzle is embodied as a two-hole nozzle which is inclined at an acute angle in the twist direction, the fuel streams of which however form such a small differential angle with respect to each other that the droplets of the oxygen-containing fuel that is unwilling to ignite in essence form a common droplet veil or mist. The injection nozzles are so directed that a separate droplet veil or mist results for both fuels. |
