  • a fuel supply device which has the task of enabling the method according to the invention to be carried out in an optimal manner.
  • This object is achieved in that one air supply line and one water supply line are connected to the water tank, while a line is provided for the supply of the fuel-air mixture, which leads into the supply line to the incineration plant or machine gas-air mixture is provided ist'Pumpe r .or "compressor or a suction device in the intake passage introducing the.

  • the combustion air is supplied, as shown in the figure, by a blower or a compressor 8 via a line 9 into the feed line 7.
  • An air filter 10 is connected upstream of the blower or compressor 8, so that the air is cleaned by a Suction line 11 flows to the blower or compressor 8. If the internal combustion engine 1 is a piston engine, the fan 8 can be omitted.

However, direct heat exchange through the combustion gases in the exhaust is also possible.
  • the heating of the water in the water tank 12 is necessary because the dissociation of the water into oxygen and hydrogen triggered by the catalyst increases in intensity with increasing temperature.

  • the fuel-air mixture can be introduced into the feed line 7 in various ways. If the machine 1 is a carburetor machine, the fuel mixture delivered from the water tank 12 is introduced into the air line 9. Since the combustion air is sucked in by the combustion machine - there is no need for the blower or compressor 8 - the fuel mixture with the sucked-in air is also fed into the combustion chamber. However, if the combustion Air is supplied by the blower or compressor 8, the fuel mixture coming from the water tank 12 is introduced into the air line immediately before the combustion chamber. In this case, the blower or the compressor 23 connected to the water tank 12 generates the pressure required to introduce the gas mixture into the feed line 7.
  • the described system ensures that a system or a machine can be operated in such a way that the fuel content of hydrocarbons 2 can be significantly reduced. Since, in addition, waste heat that would otherwise be lost is used for heating the water in the line circuit 19, the efficiency of the system or the machine 1 is significantly increased compared to known systems or machines.
  • the water temperature in the water tank 12 is kept at a relatively low temperature, e.g. kept in the range of 40 ° - 120 ° C.
  • the mixture supplied to the feed line 7 can also be heated, e.g. by a heat exchanger fed by the exhaust gases or the cooling water.

Abstract

Le carburant fourni à la machine (1) est composé d'hydrocarbures (2) et d'un mélange d'oxygène, d'hydrogène et d'air. Le mélange est produit dans un réservoir d'eau (12) dans lequel de l'eau est soumise à une dissociation oxygène-hydrogène en présence d'un catalyseur (13) et en chauffant l'eau au moyen d'une source de chaleur (21). Simultanément, de l'air fourni par un ventilateur ou un compresseur (23) est introduit dans le réservoir d'eau (12). Le mélange ainsi obtenu est amené par le conduit (7) à l'installation ou à la machine soit par compression, soit par aspiration. Ainsi, on peut réduire la proportion d'hydrocarbure dans le carburant. Le mélange sortant du réservoir d'eau (12) qui comprend moins d'azote que l'air, entraîne une diminution considérable d'oxyde de carbone et d'oxyde d'azote dans les gaz d'échappement.
