Definitions

  • the invention relates to a method for determining the gas recirculation rate at dispensers with two dispensing points (each for carburetor fuels), wherein each dispensing point (one or more) fuel flow meter and two dispensing points is assigned a common gas flow meter.
  • Gas recirculation systems at service stations have been mandatory in some European countries since the early 1990s.
  • a gas recirculation system With a gas recirculation system, the fuel vapors displaced during filling of the fuel in the tank of the motor vehicle are sucked by a gas pump and returned to the storage tank of the gas station when refueling a motor vehicle.
  • the fuel flow rate (fuel flow rate) and the gas flow rate (gas flow rate), i. the volumes of fuel or gas (vapors) delivered per unit of time are the same.
  • the terms gas recirculation rate, gas flow rate and gas volume flow are used synonymously here.
  • the gas flow rate which a gas pump delivers is adjusted either by a speed control of the drive motor of the gas pump or by a throttle valve.
  • the parameters of how to adjust this gas volume flow for the different fuel flow rates are stored in the operating electronics of the vapor recovery system (calibration data). To determine these parameters is a calibration process the gas recirculation is performed so that the gas suction of a dispensing valve, a flow meter (usually a bellows counter) is connected, the flow measurements can be assigned to the setting parameters respectively. This assignment is stored in the operating electronics of the gas recirculation system and makes it possible, in the subsequent tank operation - after the removal of the bellows counter - to adjust the gas recirculation so that the gas volume flow corresponds to the fuel volume flow.
  • the prior art monitors the gas recirculation for each bleed point with a gas flow meter (flow sensor) so that any discrepancies between the readings from the gas flow meter and readings from the bleed point fuel flow meter may indicate a gas recirculation malfunction affected Zapf Vietnamese is detected. Such a malfunction must then be signaled. This is done by transmitting a signal to a higher level system, e.g. the dispenser computer, which transmits this information to the cash register of the gas station, where it is made visible to the operator. In the event that the fault has not been resolved over a defined period of time, a shutdown signal is generated by the gas recirculation monitoring, which shuts off the dispensing point concerned so that it can no longer be refueled there.
  • a gas flow meter flow sensor
  • a petrol pump at a petrol station has two fueling points, so that two gas flowmeters are used in the petrol pump.
  • Fuel dispensers with two dispensers can be refueled on both sides at the same time.
  • simultaneous refueling operations are not very common.
  • Such a procedure is described in US 6,622,757 .
  • all fuel volumes conveyed during refueling operations are registered in a specific period of time, the gas flows of which are assigned to the one flow sensor, and the total recirculated gas volume is determined. This process is repeated as many times as there are taps on a gas flow sensor. Then, a clearly solvable linear system of equations results, so that each return point can be assigned a return ratio of the volumes (gas volume / fuel volume).
  • the return ratio may be different. This is relatively common in practice. Hereby only an average for the Zapf Vietnamese be determined, and the actual cause of error in case of deviations can not be detected.
  • gas recirculation rate / fuel delivery rate i.e. volume of gas recirculated per unit time / volume of fuel delivered per unit time.
  • the object of the invention is therefore to provide a method for determining the gas recirculation rate at filling stations that manages with a reduced number of gas flow meters (especially with only one gas flow meter per dispenser), and this still allows each refueling operation in a timely manner and to determine the gas recirculation rate and thus the recirculation rate, even if these refueling operations are overlapping in time.
  • the inventive method is designed to determine the gas recirculation rate at two dispensers (a first bleed point and a second bleed point), each bleed point having its own fuel flow meter (or even multiple fuel flow meters if multiple carburetor fuel grades are available at the bleed point) and two fueling points a common gas flow meter is assigned.
  • This gas flow meter is arranged behind a combination of the gas flows of the two fueling points. In this case, the measured values obtained by the fuel flow meters of the two fueling points and by the gas flow meter are recorded (in the form of measuring signals or after electronic processing) at short predetermined time intervals associated with each other.
  • time intervals By short time intervals is meant here time intervals that are small in comparison to the duration of a typical refueling operation, so that the measured values for the refueling operations, e.g. graphically as a function of time with sufficient temporal resolution.
  • simultaneous refueling operations at both fueling points ie at time overlapping refueling operations determined from the measured values of the fuel flow meter information about the time course of the two refueling operations for disassembling the measured sum of the gas flow of both fueling points in the first dispensing point Gas flow and a second bleed point associated gas flow.
  • the time course of the fuel flow and the associated gas flow in a refueling operation on a tapping point is generally box-shaped (eg box-shaped with steep start-up and Abschaltflanken, as in normal refueling operations, the rule), this evaluation is particularly simple. This will be explained below with reference to exemplary embodiments. However, the examples also illustrate to the person skilled in the art that an evaluation is also possible with other time profiles.
  • the method according to the invention has its limits only when the simultaneous refueling operations at the two fueling points start practically simultaneously and stop practically simultaneously, which is extremely rare in practice. If, in fact, such a case does occur, these two refueling operations could exceptionally be assigned no gas flow.
  • a method analogous to the method according to the invention can in principle also be applied to dispensers which have more than two dispensing points and in which only one gas flow meter is available for more than two dispensing points.
  • the measured fuel flow may be compared to the associated gas flow, e.g. in the form of the quotient gas recirculation rate / fuel delivery rate (return rate ratio). Or, for a given refueling operation, one compares the measured fuel volume with the associated gas volume determined by integrating the associated gas flow over time. The further evaluation or utilization of the values can thus be carried out as if the gas flow rate had been measured directly for each dispensing point.
  • each pump point can be assigned its own gas pump, or two pump points are assigned a common gas pump, which is arranged behind the junction of the gas flows of the two pump points.
  • the inventive method thus makes it possible to operate the two gas recirculation of the fueling points with a single gas flow meter in a gas pump.
  • the savings in the cost of a gas flow meter may be higher than the additional expense of evaluating the measurements, which typically can be performed in a control and monitoring device (e.g., a computer, optionally with extra electronics) already present in the dispenser.
  • the method is suitable for retrofitting petrol pumps, which have only one gas flow meter.
  • the gas recirculation rates as well as the recirculated gas volumes can be detected separately for each bleed point and thus, e.g. meet the requirements of authorities and environmental protection.
  • the condition that a certain number of refueling operations in sequence must be outside of specified tolerance limits can only be checked if this sequence can actually be evaluated.
  • the inventive method allows such a timely evaluation for each refueling operation. With the known technique explained above, this was not possible.
  • the gas flow meter is designed as a thermal flow sensor.
  • the gas flow is used to cool a heated probe. Since heat dissipation from the sensor is via the gas mass flow, ie, the mass of gas passing the sensor per unit of time, a thermal flow sensor, strictly speaking, does not measure a gas volumetric flow but a gas mass flow. However, this is exactly what is desired in the monitoring of a gas recirculation system: The gas volume flow at the inlet of the dispensing valve is to be detected. Frictional losses in the gas pump and adiabatic compression increase the gas temperature, so that changes according to the gas equation, the gas flow rate on the gas flow path.
  • the pressure increases, which likewise influences the gas volume flow.
  • a flow sensor responding to the gas flow would give incorrect readings.
  • the gas mass flow is not changed by the effects mentioned (continuity) and can be calculated back to the gas volume flow at the inlet of the dispensing valve.
  • a pulsation damper for example, configured as a muffler / condenser
  • thermal conductivity sensors in the gas flow path information about the composition of the recirculated gas can be obtained, in particular via the proportion of air in a hydrocarbon mixture (see, for example DE 199 13 968 A ).
  • ORVR vehicle coal canister vehicle
  • the measured values obtained from the fuel flowmeters are recorded, their long-term history can be used as information about the condition of fuel filters of the fuel piping. If the fuel flow over time decreases, this is a sign of deterioration of the fuel filter.
  • FIG. 1 schematically illustrated a dispenser 1 at a gas station with the most important arranged therein or the dispenser 1 associated parts, including the components of a vapor recovery system.
  • the dispenser 1 has two dispensing points, a first dispensing point 2 and a second dispensing point 2 ', so that two motor vehicles can be refueled at the same time.

  • the fuel pumps 6 and 6 ' are omitted.
  • the fuel vapors (gas) above the liquid fuel in the tank of the motor vehicle are sucked off, which is indicated by the two small arrows on the respective nozzles 12 and 12'. of the first dispensing point 2 and the second dispensing point 2 'is displayed.
  • gases are sucked in by a gas pump 14 or 14 'via a separate line guided inside the dispensing hose 10 or 10' and pass back into the storage tank 3 through a gas line 15 or 15 '.
  • the gas pump 14 or 14' is closed by a drive motor 16 or 16 'driven.
  • the drive motors 16 and 16 ' are operated via an electronic control unit 18, since in the exemplary embodiment the gas flow is controlled via the rotational speed of the drive motor 16 or 16'.
  • a pulsation damper 21 is arranged, which is designed in the form of a muffler / Kondensatabscheiders to reduce the pulsation of the gas flow.
  • the gas flow rate must be adjusted to the fuel flow rate.
  • the volume delivery rate of the gas pump 14 or 14 '(gas recirculation rate) is monitored.
  • a monitoring unit 22 is provided in the dispenser 1, which is connected to the dispenser computer 24.
  • the dispenser computer 24 receives the signals from the fuel flow meter 8 or 8 'and forwards them to the monitoring unit 22, which is connected to the control electronics 18.

  • a separate gas flow meter is provided for each dispensing point whose signals or measured values are applied to the monitoring unit in order to obtain the signals of the respective fuel flow meter and the respective gas flow meter in the control and monitoring device to compare, evaluate and use to assess the gas recirculation.
  • the dispenser 1 has only one common gas flow meter 20, whose signals or measured values are fed to the monitoring unit 22 and thus are available for the monitoring device 22.
