Definitions

  • the invention relates to a method according to the preamble in claim 1 and an apparatus according to claim 10.
  • Gasoline engines which supply the fuel liquid gas indirectly to the combustion chamber via the intake line of the combustion air, mainly use the evaporation process to bring the liquefied gas into the supply channel for the combustion air.
  • the liquefied gas is forced out of the tank by its own vapor pressure into a cooling-water-heated evaporator in which it is completely transferred from the mixing phase into the gas phase.
  • the gaseous liquefied gas is supplied under pressure to its own distribution bar, from which each cylinder, computer-controlled via clocked solenoid valves, the appropriate amount of gaseous fuel is injected into the incoming combustion air for each combustion cycle.
  • DE 201 01 672.9 it is proposed to activate the on-board air conditioning system via a knock sensor or a temperature probe in the exhaust duct when a temperature limit is exceeded.
  • the air conditioner supplies coolant to an evaporator through which the intake air flows.
  • the on-board air conditioning system limits the cooling temperature to approx. 5 0 C. This configuration allows cooling only up to this temperature.
  • the system works with conventional refrigerants and not with LPG, so it does not use the dual character of fuel and cooling medium.
  • the object of the present invention is to render the fuel supply process thermally more stable and the thermodynamic cycle thermodynamically more efficient.
  • the present method has advantages at several levels. It saves components, makes the fuel supply of the fuel LPG ther- more robust and increases the efficiency of the thermodynamic cycle.
  • a fuel evaporator nor a fuel pump in the liquefied gas tank is required because the air conditioning compressor gaseously aspirates the liquefied gas, which is both fuel and refrigerant in the process described herein.
  • the fuel supply system gains thermal stability.
  • any heat input into the fuel on its way from the LPG tank to the injectors had to be compensated for by increased pressure or additional cooling, while at this point in the refrigeration cycle additional warming is welcome as it is the gas phase of the LPG Stabilizes fuel and ensures that the compressor is supplied only liquid gas in the gas phase.
  • Figure 1 forms a fuel-cooling system with direct injection of
  • FIG. 2 shows a fuel-cooling system with injection of the fuel into the intake passage of the gasoline engine, with FIG. 2 essentially differing from FIG. 1 by the omission of the high-pressure fuel pump. For this reason, FIG. 1 will be described in greater detail below.
  • FIG. 1 is a schematically illustrated fuel-cooling system whose components fuel tank, device for fuel heating, compressor, condenser, high-pressure fuel pump, expansion valve of the refrigeration cycle, two parallel evaporators connected by fuel lines are connected to a circuit. It shows a diversion from 120 fuel in the high-pressure fuel pump which leads to the fuel rail with the injection valves of a (not shown here) gasoline engine, where the fuel is injected directly into the combustion chamber.
  • Figure 1 also shows schematically the connection of an air conditioning circuit with which, for example, the cabin of a motor vehicle can be air-conditioned.
  • the compressor 2 of the fuel-cooling circuit sucks in gaseous liquefied petroleum gas and compresses it. In a preferred embodiment, it is driven independently of the internal combustion engine, preferably electrically. This has the advantage that the compressor 2 can start even before the engine starts and thereby the fuel supply system (7 - 11) when starting
  • combustion chamber of the internal combustion engine is injected.
  • the one branch 19 supplies a heat exchanger 20, through which a heat transfer medium, preferably a water-antifreeze mixture flows, which receives the cold of the evaporating liquefied gas, from where it to another
  • heat exchanger 22 is pumped inside the cabin by a circulation pump 23. By suitable coupling to the heating circuit, the desired temperature can then be adjusted by mixing the heat transfer media.
  • the other strand 24 leads to two evaporators 25,26 that of the coolant
  • the combustion air temperature of the evaporator 25 which is first passed through by the combustion air, is regulated in such a way that it precipitates the moisture contained in it and is discharged downwards in liquid form 28.
  • a refrigerant line 30 continues downstream in the direction of the compressor 2 after the refrigerant line 19 of the heat exchanger has previously been added.
  • the fuel tank 1 is connected by a line 12. From the fuel tank 1, the fuel consumed in the combustion process is supplemented via an expansion valve 16, whereby it evaporates to cool the combustion air 27.

Abstract

L'invention propose un procédé et un dispositif qui utilise simultanément dans un unique système couplé le caractère double, particulier parmi les carburants habituels pour moteurs à combustion interne, du gaz liquéfié, pour pouvoir utiliser ce dernier aussi bien comme carburant pour un moteur à combustion interne que comme fluide de refroidissement dans un circuit de refroidissement. En couplant l'amenée de carburant aux soupapes d'injection en des emplacements appropriés du circuit de climatisation, on peut utiliser une partie du circuit de climatisation en même temps comme groupe d'amenée et pour l'injection de carburant. En même temps, l'évaporateur du circuit de climatisation est utilisé non seulement pour la climatisation de l'habitacle, par exemple d'un véhicule automobile, mais également pour refroidir jusqu'en dessous du point de congélation de l'eau l'air de combustion apporté au moteur à combustion interne. Cela améliore le rendement thermodynamique du processus de combustion largement au-delà des limites de ce que l'on peut obtenir sur les moteurs à essence.
