Definitions

  • the invention relates to a method and a device for operating a tank ventilation system and a tank ventilation system.
  • Vehicles especially motor vehicles, are known to be equipped with tank venting systems to prevent evaporation of hydrocarbons from the fuel tank to the atmosphere.
  • the tank ventilation systems are often equipped with activated carbon filter.
  • activated carbon filter can only absorb a limited amount of hydrocarbons and must be regenerated, that is purified, at least when reaching a certain degree of saturation.
  • the activated carbon filter can thus serve as an intermediate storage for the hydrocarbons dissolved from the fuel, whereby the hydrocarbons dissolved from the fuel can be fed to combustion of an internal combustion engine.
  • DE 10 2007 002 188 A1 discloses a tank ventilation system for a hybrid vehicle, wherein the tank ventilation system comprises at least one fuel tank and a suction line leading from a regenerable filter device to an intake tract of the internal combustion engine.
  • a control device is provided, which can actuate different valve devices for purging the filter device, so that ambient air can be fed to the internal combustion engine through the filter device and the suction line.
  • the control device is also designed so that it in a pure electric operation of the hybrid vehicle, the internal combustion engine in response to a Loading state of the filter device or Spülgaskonzentration connects.
  • US 2005/0211228 A1 discloses a fuel vapor treatment system for an internal combustion engine.
  • a pump generates a gas flow within a metering passage having an orifice.
  • a differential pressure sensor detects a pressure difference between both ends of the orifice.
  • switching valves are arranged to generate a first concentration measurement state in which the measurement passage is opened at both ends thereof and in which the gas flowing through the measurement passage is the atmosphere and to generate a second concentration measurement state in which the measurement passage its two ends communicating with a container and in which the gas flowing through the measuring passage is a fuel vapor which is an air-fuel mixture provided by the container.
  • An ECU calculates a fuel vapor concentration based on a pressure difference detected in the first concentration measurement state and a pressure difference detected in the second concentration measurement state.
  • the object underlying the invention is to provide a method and a corresponding device for operating a tank ventilation system as well as a tank ventilation system which enable flexible tank ventilation and contribute to simplifying a desired fuel injection.
  • the invention is characterized by a method and a corresponding device for operating a tank ventilation system with an adsorption vessel, a regeneration channel and a pump.
  • the adsorption vessel is used for collecting and buffering fuel vapors emerging from a fuel tank, wherein the adsorption vessel can be flowed through by a purging air stream.
  • the regeneration channel connects the adsorption vessel with an intake passage.
  • the pump is arranged in the regeneration channel and designed to suck the purge air from the adsorption and to add an intake air in the intake passage.
  • a density of the purge air flowing in the regeneration channel is determined.
  • a purge air mass flow flowing in the regeneration channel is determined depending on the density of the purge air and a predetermined pump characteristic of the pump.
  • this can make a contribution to form a precontrol of a lambda control and / or a controller for fuel metering sufficiently accurate and / or to keep control fluctuations in the fuel metering low.
  • the pump in the regeneration passage between the adsorption vessel and the intake passage makes it possible to carry out a purging of the adsorption vessel independently of a negative pressure prevailing in a suction tube of the internal combustion engine. In this way, an independent of an operating range of the internal combustion engine flushing of the adsorption vessel can take place.
  • the density of the scavenging air flowing in the regeneration channel is determined as a function of a detected hydrocarbon concentration of the scavenging air and / or a temperature of the intake air and / or a Temperature of an ambient air flowing into the adsorption and / or a detected pressure difference in the regeneration channel.
  • the pressure difference represents a difference between a first pressure downstream of the pump and a second pressure upstream of the pump.
  • the temperature or temperatures and the pressure difference can be detected with already existing in existing systems sensor elements, whereby a cost-effective implementation is possible. Sensor elements for measuring the hydrocarbon concentration are also being considered for future systems.
  • a speed of the pump is detected and the purge air mass flow determined depending on the speed of the pump.
  • the pump is designed such that a volume flow rate of the pump is proportional to a rotational speed of the pump.
  • the pump is designed as a radial pump. This allows a cost-effective implementation of a tank ventilation system, since a radial pump can be carried out inexpensively compared to other pump types with comparable performance and a control or regulation of a radial pump can be easily formed, since a change in the pump speed both the volume flow rate and the pressure and thus the Power consumption changed.
  • the pump is designed as a vane pump.
  • higher pressure differences can be generated with a vane pump.
  • a control of the pump and / or a scavenging air valve, which is arranged in the regeneration channel, is controlled.
  • the invention is characterized by a method and an apparatus for operating a tank ventilation system with an adsorption container, a regeneration channel and a pump.
  • the adsorption is used for collecting and buffering emerging from a fuel tank fuel vapors, wherein air can pass through an air channel into the adsorption and the adsorption is flowed through by a scavenging air.
  • the regeneration channel connects the adsorption vessel with an intake passage.
  • the pump is disposed in the air passage and configured to exhaust the purge air from the adsorption vessel and to add an intake air into the intake passage.
  • a density of the purge air flowing in the regeneration channel is determined.
  • a purge air mass flow flowing in the regeneration channel is determined depending on the density of the purge air and a predetermined pump characteristic of the pump.
  • the arrangement shown has a tank ventilation system 100, a device 200 for operating the tank ventilation system 100, an internal combustion engine 90 with an intake tract, and a fuel tank 20.

  • the adsorption container 10 is arranged downstream of the tank ventilation channel 24 downstream. Hydrocarbons which evaporate due to heating of the fuel are conducted via the tank venting channel 24 into the adsorption vessel 10.
  • the adsorption container 10 includes, for example, an activated carbon filter 12 for temporarily storing the outgassing from the fuel tank 20 hydrocarbons. Such an activated carbon filter 12 can only temporarily store a limited amount of hydrocarbons. The activated carbon filter 12 must therefore be regenerated, that is freed from the hydrocarbons absorbed therein.
  • the adsorption container 10 therefore has, for example, an air channel 14 in which air can flow from the environment into the adsorption container 10.
  • Both in the air channel 14 and in the tank venting channel 24 can each be arranged a controllable valve.
  • the adsorption vessel 10 is connected to the intake passage 60, which is part of the intake tract of the engine 90, by means of the regeneration passage 50.

  • an opening degree of the scavenging air valve 35 for scavenging the adsorption vessel 10 may be adjustable in the regeneration passage 50 depending on a predetermined operating range of the engine 90 and / or on a predetermined loading level of the adsorption vessel 10 and / or the hydrocarbon concentration of the scavenging air.
  • a pressure generating device such as a pump 30 is disposed in the regeneration passage 50.
  • the pump 30 is designed to generate a pressure difference in the regeneration channel 50, so that air from the environment can be sucked in via the air channel 14 and the activated carbon filter 12 can be flowed through by the air and thus cleaned.
  • the purging air enriched with fuel vapor is added to intake air flowing in the intake passage 60, and thus can be supplied to combustion of the engine 90.
  • the pump 30 may be arranged, for example, in the engine compartment.
  • the purge valve 35 may be disposed downstream of the regeneration passage 50 both before and after the pump 30.
  • the tank ventilation system 100 may, for example, various sensor elements 81, 82, 83, 83 ', which are designed to detect different state variables.
  • the respective detected state variables can, for example, be evaluated by the device 200 for operating the tank ventilation system 100 such that a density of the purging air flowing in the regeneration channel 50 can be determined.
  • the tank ventilation system 100 may include at least a first sensor element 81 configured to detect a hydrocarbon concentration of the purge air in the regeneration channel 50.
  • the first sensor element 81 for detecting the hydrocarbon concentration can be arranged, for example, in the regeneration channel 50. An arrangement is possible both near the engine and near the tank.
  • the tank ventilation system 100 may comprise at least one second sensor element 82, which is designed to detect a temperature of the purging air in the regeneration channel 50.
  • the tank ventilation system 100 may for example comprise a third sensor element 83, 83 ', which is designed to detect a pressure in the intake duct 60 and / or in the air duct 14, via which ambient air can flow into the adsorption tank 10.
  • the third sensor element 83 ' which is arranged for example in the air duct 14, an ambient pressure can be detected.

  • a scavenging air mass flow can be determined.
  • the pump 30 is designed such that the volume flow rate of the pump 30 is proportional to a rotational speed of the pump 30.
  • the purging air mass flow (M) can be determined in this case, for example, depending on the product of the density and a volume flow in the regeneration channel 50, wherein a temporal first derivative of the volume flow rate of the pump represents the volume flow.
  • the pump 30 may be formed, for example, as a radial or vane pump.
  • the radial or vane pump can be driven for example with a brushless electric motor. This makes it possible, for example, to detect the rotational speed and / or a power consumption of the pump 30, for example by means of the device 200 for operating the tank ventilation system 100.
