Definitions

  • a fuel delivery system may be disposed in a fuel tank of a motor vehicle and may be used to supply an internal combustion engine with fuel.
  • the fuel delivery system may have a fuel filter to purify the fuel of undesirable particles before being supplied to the internal combustion engine.
  • the fuel in the fuel tank and in particular in the fuel filter can outgas. When restarting, this can lead to higher pressure build-up times in the fuel filter, since first the gases must be compressed and liquefied.
  • fuel filters can be kept under pressure under standby conditions, in particular under system pressure. However, this leads to a life-time stress on the fuel filter.
  • the EP 1 126 157 A2 discloses such a fuel supply device.
  • the WO 2006/079 402 A1 proposes to maintain a lower pressure throughout the system via a second pressure valve in the Abstellfall.
  • the WO 2008/052 873 A1 describes the problem that the filter is heavily loaded in the Abstellfall and also proposes to reduce the pressure throughout the system.
  • a fuel delivery system includes a fuel filter that cleans or filters a fuel delivered from a storage pot to an internal combustion engine. Furthermore, the fuel delivery system has a suction jet pump (SSP) for filling the storage tank with fuel from a fuel tank.
  • the fuel filter is hydraulically connected via a tether with the suction jet pump.
  • a first pressure valve is provided which opens automatically in the direction of the suction jet pump when a pressure in the fuel filter exceeds a first threshold.
  • the idea of the invention is based on integrating a pressure valve with a defined opening pressure into a feed of the ejector pump.
  • the opening pressure is between a vapor pressure of the fuel and the system pressure. That is, the opening pressure of the first pressure valve may be selected at the pressure limit for outgassing of the fuel.
  • a subsystem pressure is applied to the fuel filter.
  • the fuel delivery system cost-effective filter housing such as polyoxymethylene (POM)
  • POM polyoxymethylene
  • the overflow of the fuel can be used to feed the ejector. That is, the first pressure valve can pass during operation of the internal combustion engine or the fuel delivery system funded by a fuel pump to the reservoir cup and not required by the internal combustion engine amount of fuel as a flow in the haulage. In this way, the overflow can be used to power the ejector. This in turn allows a higher efficiency of the fuel delivery system compared to previous solutions in which the spill freely flows, i. e.g. was returned to the fuel tank.
  • the fuel delivery system may for example be used in a fuel tank of a motor vehicle.
  • the motor vehicle may be, for example, a motor vehicle with an internal combustion engine, such as an internal combustion engine.
  • the motor vehicle may have an electric drive and be designed as a hybrid vehicle.

  • the fuel filter and in particular the filter housing can be designed to be used at a system pressure of 7 to 8 bar.
  • the fuel can be pumped from the fuel tank into the interior of the storage pot via a suction line of the suction jet pump.
  • the fuel can be pumped out of the storage pot by a fuel pump, in particular an electric fuel pump, to the filter and then through a supply line to an injection system of the internal combustion engine.
  • the suction jet pump can be arranged on the storage pot and designed as a horizontal or vertical suction jet pump. Due to the tethering of the suction jet pump fuel is delivered directly from the fuel filter to a suction line. At the connection point between the suction line and the haulage line, a constriction is provided after which the cross section in the suction line increases again. By increasing the cross section, the pressure in the intake manifold decreases, so that fuel from the fuel tank is sucked through the intake manifold into the storage pot.
  • the suction jet pump By supplying the suction jet pump with fuel directly from the fuel filter, a clean supply of the suction jet pump can be ensured.
  • the direct supply of the suction jet pump from the fuel filter the life of the electric fuel pump can be increased.
  • the suction jet pump can be turned “on” and "off".
  • the first pressure valve may also be referred to as a partial pressure relief valve, pressure relief valve or pressure relief valve.
  • the first pressure valve is arranged on or in the treble line.
  • the first pressure valve has a defined opening pressure. That is, the pressure valve opens only when a predetermined first pressure threshold is exceeded. In this case, when the first threshold value is exceeded, the first pressure valve opens automatically, that is to say without the need for activation.
  • the first pressure valve limits the maximum pressure prevailing in the fuel filter in the shutdown case of the fuel delivery system.
  • the first pressure valve may have a seal and a spring. By means of the spring, the opening pressure or the first threshold value can be determined, for example, via the spring constant.
  • the first threshold value lies between a vapor pressure of the fuel at a shut-off temperature of the fuel delivery system or of the motor vehicle and a system pressure.
  • the vapor pressure of the fuel can correspond to a pressure limit of the outgassing of the fuel. In this case, this vapor pressure can depend both on the temperature and on the type of fuel.
  • the shutdown temperature can be between 0 ° C and 60 ° C, for example.
  • the first threshold is selected such that the first pressure valve opens at the highest possible shutdown temperature in the fuel filter of, for example, 60 ° C and at a fuel having the highest vapor pressure, only when the subsystem pressure in the fuel filter is high enough To prevent outgassing.
  • the first threshold value is between 1.5 bar and 4 bar.
  • the first threshold is greater than 2.2 bar.
  • the first threshold is 2.5 bar.
  • the fuel delivery system further comprises a control unit and a fuel pump for delivering fuel from the storage pot to the fuel filter.
  • the control unit is designed to control the fuel pump in such a way that a supply to the ejector pump is switched off by operating the fuel pump at a pressure which is less than the first threshold value of the first pressure valve.
  • the feeding of the suction jet pump that is to say the supply of the suction jet pump with the propellant fuel
  • the fuel pump which can be designed as an electric fuel pump.
  • the fuel delivery system at sufficiently high tank level in the fuel tank and at normal operating parameters of the injection system or the internal combustion engine are operated at a pressure below the first threshold pressure.

  • a second pressure valve is provided which opens to the fuel tank when a pressure in the flow line exceeds a second threshold.
  • the second threshold is greater than the first threshold.

  • the second pressure valve may be similar to the first pressure valve, for example, designed as a spring-loaded pressure relief valve and having a predetermined opening pressure.
  • the opening pressure of the second pressure valve is higher than the first pressure valve, since the temperatures rise towards the internal combustion engine and thus a higher pressure on the combustion engine side of the fuel delivery system is appropriate to avoid outgassing of the fuel.
  • the second pressure valve opens in the direction of the fuel tank and can run, for example, excess funded fuel from the flow line back into the fuel tank or in the storage tank.
  • the second threshold value is between 5 bar and 7.5 bar.
  • the second threshold is 7.5 bar.
