  • the fuel supply of an automobile engine is to supply the liquid fuel of the fuel tank by a fuel pump or a high pressure pump.
  • the fuel pressures supplied by these pumps are supplied at a pressure so high that they cannot be used in the combustion chamber.
  • the engine is equipped with a fuel pressure regulator in order to prevent such high pressure fuel from being supplied directly to the combustion chamber immediately.
  • the fuel pressure regulator serves to adjust the fuel pressure to be supplied to the combustion chamber and the fuel pressure to be returned to the fuel tank to receive the excess pressure of the fuel pumped by the pump.
  • the fuel pressure to be supplied to the combustion chamber is kept in the fuel supply pipe in which the injector, which is an injector for finally injecting fuel into the combustion chamber, is kept and the remaining fuel pressure is sent back to the fuel tank.

  • the fuel injection time supplied to the combustion chamber also coincides with the engine speed.
  • the injector when the engine speed is low, the injector is open for a long time, and the fuel injection time is long, so the amount of fuel supplied to the combustion chamber is increased, and when the engine speed is high, the time for injecting fuel is short, because the injector is short, the combustion chamber is short. The amount of fuel supplied to the car will also be reduced.
  • the fuel supply pressure is maintained the same by the fuel pressure regulator, but it may appear that there is no problem in the fuel supply because the flow rate supplied to the combustion chamber also changes according to the fuel injection time.
  • the fuel supply pressure should not be regarded as the correct fuel supply only by matching the fuel injection time according to the engine speed under the same fuel supply pressure. Since the load on the engine is different when the engine is lowered, the fuel pressure to be supplied to the combustion chamber must be selectively supplied according to the conditions of the different roads.
  • the load on the engine also works differently depending on how much a person rides or rides less, or when a lot of loads are loaded with less load.
  • the need to supply selectively according to the conditions can be seen as the key to correct fuel supply.
  • the existing fuel supply technology does not have the technology to automatically adjust the fuel pressure according to various road conditions or driving conditions during driving. Therefore, the fuel pressure regulator is adjusted based on the fuel with the highest fuel consumption among the conditions so that the fuel supply pressure is not insufficient even when driving with a lot of luggage. At this time, there is a big problem that can lead to fuel waste.

Abstract

La présente invention se rapporte à un appareil d'alimentation automatique d'atomisation de carburant de véhicule et, plus spécifiquement, à un appareil d'alimentation automatique d'atomisation de carburant de véhicule, qui, lors de l'acheminement du carburant liquide à une chambre de combustion d'un moteur, ne permet pas une alimentation directe forcée au moyen d'une pompe à carburant d'un réservoir de carburant, mais permet à la quantité de carburant requise d'être apportée en fonction d'une force d'aspiration de piston de la chambre de combustion et permet également au carburant liquide d'être automatiquement apporté dans un état atomisé, ce qui permet de mettre en contact sans à-coups et de mélanger l'air de combustion et le carburant atomisé de telle sorte qu'une combustion complète soit réalisée dans la chambre de combustion, que la sortie d'un véhicule soit améliorée, que l'apparition de bruit soit réduite, qu'il n'y ait pas de production de gaz d'échappement au moment de l'allumage et qu'on puisse économiser le carburant du fait d'une alimentation en carburant appropriée. La présente invention permettant d'atteindre l'objectif précité se rapporte à un appareil de commande automatique de la pression d'alimentation en carburant de véhicule et de l'atomisation de carburant, l'appareil comprenant : une partie corps principal ; une partie de commande de carburant installée sur l'intérieur de la partie corps principal ; une partie d'alimentation en carburant installée au niveau de l'extrémité inférieure de la partie de commande de carburant ; une partie de sortie de carburant installée au niveau de l'extrémité supérieure de la partie de commande de carburant ; et une partie de conversion d'alimentation en carburant installée au niveau de l'extrémité supérieure de la partie de sortie de carburant de manière à changer le chemin d'alimentation en carburant.
