Definitions
- the present invention relates to a method for injecting a fuel into an internal combustion engine or a nozzle engine, wherein after compression, fuel is injected into the internal combustion engine or the nozzle engine, and to an injection nozzle for injecting a fuel into an internal combustion engine or a jet engine, with a fuel injection into the internal combustion engine or the jet engine taking place after compression.
- the present invention aims to further reduce the consumption of fuels, in particular in an internal combustion engine or a jet engine.
- an inventive method for injecting a fuel into an internal combustion engine Machine or a jet engine essentially characterized in that the fuel is heated to a high temperature before the injection and the fuel is injected in the vapor state.
- a very high pressure is created in an injection nozzle, by means of which the fuel or fuel in the form of steam is pressed into a piston chamber of a downstream internal combustion engine or into a jet engine.
- the fuel reaches an even higher temperature, in particular due to friction.
- the high temperature that the fuel has at the time of injection and the first contact with oxygen molecules results in an almost explosive combustion.
- the method according to the invention also enables combustion or the use of mineral fuels with higher viscosities and of vegetable fuels or of ethylene glycols and other flammable liquids by heating the fuel.
- the fuel is heated to a temperature above its self-ignition temperature.
- Raising the temperature above the self-ignition temperature of the fuel immediately before being discharged from an injection nozzle can subsequently dispense with any additional ignition device.
- preheating may also be omitted or electrical ignition of the fuel in gasoline engines is no longer necessary.
- fuels with higher autoignition temperatures can be provided according to a further preferred A s Solutionssfor that the vapor fuel is ignited when it emerges from an injection nozzle, so that the ignition takes place directly at the outlet from an injection nozzle and separate, additional ignition devices are not required.
- the heating and / or ignition of the fuel by electrical resistance, spark discharge, induction, a piezo element or the like. is made.
- the fuel be preheated in the injection nozzle before it is heated, as corresponds to a further preferred embodiment of the method according to the invention.
- Type is essentially characterized in that a heating element for heating the fuel to be injected is integrated in the injection nozzle. By means of such a heating element, the desired increase in the temperature of the
- the heating element is formed by a resistance heater, such a resistance heater correspondingly allowing the desired high temperatures of the fuel to be achieved.
- an ignition device in particular ignition electrodes, is provided at the outlet of the injection nozzle for igniting the vaporous fuel.
- Such an ignition device, in particular ignition electrodes can be easily integrated directly into the injection nozzle at its outlet end.
- the fuel is supplied to the injection nozzle in a conventional manner or through a pressurized storage container, the injection of the fuel or the triggering of the injection process being able to be carried out mechanically and / or hydraulically, for example using a lifting magnet.
- an injection nozzle is generally designated 11, a magnet coil 1 and a magnetic core 2 being provided in the injection nozzle in order to initiate the injection process in a manner known per se or to control.
- a fuel supply line with one or more channels for supplying a possibly preheated fuel and / or fuel which is already under an increased pressure into the interior of the injection nozzle is indicated by 3 ' .
- connection 4 denotes a connection which is accommodated in an insulation 5, the electrical connection 4 serving on the one hand to supply the heating element or evaporation element 6 formed for example by a resistance heater and on the other hand supplying the ignition device or Ignition electrode 10 for igniting the vaporous fuel, which has a high temperature when it emerges from the injection nozzle 11.
- the heating of the fuel in the injection nozzle 11 to a high temperature and a conversion to the vapor state makes it possible overall to reduce the amount of fuel required to operate an engine or a jet engine, in addition to corresponding environmental protection requirements with regard to subsequent combustion of the fuel can be achieved.
