Definitions

  • the present invention relates to a device for automatically introducing means forming an additive into the fuel tank of a motor vehicle.
  • the exhaust gases of compression-ignition engines and in particular diesel engines which use diesel as fuel, contain both gaseous pollutants such as hydrocarbons, nitrogen oxides and carbon monoxide CO and solid pollutants which mainly consist of soot particles.
  • Such a filter is installed in the exhaust line of the engine and comprises porous ceramic filter elements which are traversed by the exhaust gas and which make it possible to retain the solid particles suspended in these gases.
  • the filter elements are loaded into soot particles and clog gradually. Unclogging of the filter elements can be achieved by burning the soot deposited on these elements during operation of the engine.
  • the soot burns at temperatures of the order of 550 to 600 ° C.
  • Such thermal levels are only rarely achieved by the exhaust gas of a diesel engine of a passenger vehicle. It is therefore necessary to promote the start of the regeneration of the filter elements, by adding to the fuel means forming an additive allowing in particular to lower the soot combustion temperature.
  • the most commonly used additives consist of organometallic compounds which, mixed in specific proportions with diesel, are injected into the combustion chamber, by the injection pump, and are found in the exhaust gas.
  • composition of the additives may be necessary to adapt the composition of the additives to the characteristics of the engine in which they are used.
  • Another known solution is to incorporate the additives to the fuel, automatically, inside the vehicle tank after each filling operations of this tank.
  • the dosage of the additives is carried out so that the concentration of fuel additive inside the tank remains perfectly constant.
  • the organometallic additives become metal oxide particles intimately mixed with the soot particles.
  • the predetermined concentration of the additive in the fuel is set at a value such that the fuel injected into the engine cylinders constantly contains an amount of additive sufficient to lower the soot combustion temperature in the particulate filter of the vehicle, up to at a level ensuring satisfactory combustion even when the engine load level is low.
  • the initial level of fuel in the vehicle is measured.
  • the tank, prior to each replenishment operation of this tank the final level of the fuel in the tank is measured and, on the one hand, the quantity of fuel introduced into the tank at each replenishment operation from the initial level is determined. and the final level measured and, secondly, the amount of additive contained in a quantity of fuel equal to the amount introduced into said tank.
  • the measurement and recording of the fuel level in the tank are automatically controlled when opening and closing a filling cap of the tank filling pipe or when opening and closing a shutter of a portion of the vehicle body giving access to filling means of the tank.
  • the amount of additive means injected at the present time is determined so as to obtain permanently in the fuel tank, an additive rate of the order of 10 ppm.
  • this ratio depends on the temperature of the gases reached in the regeneration phase, which itself is highly dependent on the running conditions of the vehicle.
  • the regeneration can be done on the motorway, it is relatively easy to obtain exhaust gas temperatures of 600 ° C in the particulate filter, the additive then being practically unnecessary.
  • the particle filter must be regenerated during an urban run, the gas temperature reaches at best 450 ° C and the additive is then of a precious help.
  • the additive dosage is now fixed and defined, so that we obtain an additive ratio on carbon of 1.4% in urban traffic. Operation current is not optimized when the use of the vehicle is mostly extra-urban type.
  • an overdose of additive can also lead to cracking or even to a breakage of the particulate filter.
  • the object of the invention is therefore to solve these problems.

  • the suction pipe 4 has an end portion opposite the pump 3 which is dipped inside the tank 2 to open, at its lower part, in the form of a suction strainer 6.
  • the pump 3 is connected to the cylinders of the engine 1 by lines each providing the supply of an injector 9 associated with a cylinder of the engine.
  • the tank 2 is equipped with a level gauge 7 to determine the position of the diesel fuel level in the tank 2.
  • the tank 2 also comprises a filler pipe 8 opening into the upper part of this tank 2 and equipped with a closure cap 8a.
  • the exhaust line of the vehicle whose propulsion is provided by the diesel engine, comprises a particulate filter, not shown, for stopping the soot particles formed in the exhaust gas of the engine.

  • the automatic additive introduction device comprises an electronic control unit 20 integrated in the vehicle and making it possible to provide all the adjustment and monitoring functions of the introduction of additive in metered quantities into the fuel tank. fuel 2 of the vehicle.
  • the automatic additive introduction device also comprises means for measuring the amount of fuel introduced into the reservoir 2 during each replenishment operation.
  • these measuring means are formed for example by a mono-directional flowmeter 17 placed directly in the tubing 8 for filling the fuel tank 2.
  • the flowmeter 17 is connected to the control unit 20 by an electric cable 21 which makes it possible to transmit automatically to said housing 20 the amount of fuel introduced into the tank 2 when refilling this tank 2 with fuel.
  • the level gauge 7 associated with the fuel tank 2 is connected by an electric cable 22 to the housing 20, so as to transmit to this housing 20 as well as to the driver of the vehicle, an electric signal representative of the fuel level inside. of said tank 2.
  • the electronic box 20 is connected by electric cables, respectively 23 and 24, to the pump 13 and the injector 14, so as to transmit to these elements of the additive introduction device a control signal ensuring an injection into metered quantity of additive in the tank 2 of fuel, under the conditions which will be described later.
  • a level gauge 18 connected to the control unit 20 by an electric cable 25 makes it possible to transmit to this housing 20 an electrical signal when the level of additive in the tank 10 has reached a minimum position close to the bottom of this tank 10.
  • a temperature sensor 19 disposed in the additive reservoir 10 makes it possible to transmit to the electronic control unit 20, via an electric cable 26, a signal representative of the temperature of this liquid additive inside said reservoir 10.
  • the electronic unit 20 comprises at least one output 27 constituted by at least one electrical cable connected to lights which can be located advantageously in the passenger compartment of the motor vehicle.
  • the ignition of a first indicator is obtained when the level of additive detected by the gauge 18 in the additive reservoir 10 has reached the position corresponding to the minimum level near the bottom of the reservoir 10 and the ignition of a second indicator light is obtained when the level of fuel detected by the gauge 7 in the fuel tank 2 has reached a position corresponding to the minimum level close to the bottom of this fuel tank 2.
  • the electronic unit 20 also receives, as input data, an electrical signal representative of the concentration of additive that it is necessary to maintain in the fuel, that is to say in the diesel fuel injected into the cylinders 9 of the engine 1. depending on the driving conditions of the vehicle.
  • this concentration of additive depends on the driving conditions of the vehicle.
  • means 30 for analyzing the running conditions of the vehicle and for determining vehicle running conditions that are favorable or unfavorable for the regeneration of the depollution means, are used to deliver to this electronic box 20 a nominal metering information corresponding to unfavorable driving conditions, for example of urban type, or minimal metering information, corresponding to favorable driving conditions, for example on the motorway.
  • This information is for example delivered by storage means designated by the general references 31 and 32 on this figure 1 , which then deliver, depending on the rolling conditions encountered, the nominal dosing information or the minimum dosing information to the electrical box 20 in order to control the additive injection means accordingly.
  • the device according to the invention it is therefore possible to establish the concentration of additive in the fuel at the value just needed.
  • the diesel can indeed be additivé in two stages, a first time during a replenishment and a second time, if this is deemed necessary after analysis of the driving conditions of the vehicle.
  • the two dosages indicated above namely the nominal dosage corresponding to the rolling conditions unfavorable to the regeneration and already implemented in the devices for introducing the state. of the technique, and the minimum dosage adapted to conditions favorable to regeneration, such as for example when driving on the motorway.
  • This analysis of the driving conditions of the vehicle may for example be based on an analysis of a driving history of the vehicle. So, by for example, if the use of the vehicle over the last 50 kilometers traveled corresponds to a taxi in town, then the additive is injected at the nominal dosage. In the opposite case, that is to say for example if the vehicle is used on the highway, it is possible to inject the minimum dosage.
  • the means for analyzing the running conditions of the vehicle detect a change in conditions, such as for example a transition from a highway taxi to a city taxi, we can inject an additional amount of additive to bring the concentration to the nominal dosage value.
  • Such a strategy makes it possible, for example, for vehicles essentially traveling on motorways, to operate mainly with a minimum dosage of additive.
  • a first strategy for choosing the minimum dosage is illustrated in the table of the figure 3 .
  • This minimum dosage is chosen so that the additive ratio on carbon is constant regardless of the type of rolling. In the illustrated example, this is dose on the highway at 6 ppm instead of 10 ppm. When returning to urban use, the soot in the particulate filter is correctly additive.
  • the figure 4 represents a table illustrating a second strategy of minimal dosage choice.
  • the minimum highway dosage is lowered to the level just needed to regenerate under these favorable driving conditions.
  • the highway is thus measured at 2 ppm instead of 10 ppm, which represents a very significant gain in durability for the customer.
  • a difficulty in this case is that during a return to urban use, the soot in the particulate filter are sub-additive and it is impossible to add the additive later in the soot. This can then lead to a difficulty in burning these soot. But such a case is rare, because after a runway road / highway, the particle filter usually contains little soot. In fact, either they burned naturally thanks to the temperatures reached on the highway, or the operating supervisor of the particulate filter took advantage of the favorable conditions to trigger the regeneration in an anticipated manner. In addition, soot accumulated subsequently during a taxi in the city have the right dosage which allows to initiate combustion in the particulate filter. Moreover, the possible problem does not only one regeneration in the city. Indeed, if the vehicle stays longer in town, the dosage then becomes nominal for subsequent regenerations.
  • a possible alternative is to trigger an exceptionally regeneration at a higher temperature to compensate for the underdosing additive, considering that the impacts in consumption and dilution are bearable because exceptional and not critical for a vehicle traveling in the city.
  • the table of the figure 5 shows that the gain in additive consumed is considerable especially for the second strategy but is also interesting for the first strategy.
  • the bonus acquired at the beginning of life is preserved in some way in the form of an additive not consumed subsequently.
  • Some elements of the additive introduction device may be constituted by elements conventionally used for the construction of motor vehicle engines and their control members.
  • the additive injection assembly comprising the pump 13, the pressure regulator 16 and optionally the injector 14 can be constituted by a conventional injection device as used on motor vehicles comprising a injection engine.
  • the flowmeter 17 directly measures, in the pipe 8, the amount of fuel introduced into the tank 2.
  • the flowmeter 17 therefore transmits through the electric cable 21 the signal representative of the quantity of fuel introduced into the tank 2.
  • the electrical contact of the vehicle makes it possible to put into operation the electronic control unit 20 for determining and carrying out the injection of additive into the fuel tank 2.
  • control unit 20 calculates the quantity of additive to be introduced into the tank 2, as a function of the quantity of fuel introduced into this tank 2 and the concentration of additive of the fuel delivered by the means of fuel. analyzing the driving conditions 30, 31, 32 to obtain satisfactory operating conditions of the particulate filter.
  • the signal representative of the quantity of additive to be introduced into the fuel tank 2 is converted into a control signal of the injection pump 13 and to a control signal of the injector 14.
  • the control signal of the injector 14 keeps the injector open for a time sufficient to effect the injection of the determined amount of constant pressure additive into the fuel tank 2, the pump 13 remaining in operation for a time sufficient to carry out this injection directly into said fuel tank 2.
  • the gas oil contained in the tank 2 has an additive concentration which corresponds perfectly to the concentration necessary to obtain a satisfactory operation of the particulate filter according to the determined driving conditions.
  • the concentration of additive of the gas oil in the tank 2 is perfectly homogeneous due to the mixing provided by the injection pump 3.

  • the temperature measured by the gauge 19 can be taken into account by the control unit 20 to calculate the injection time of the additive at constant temperature. Indeed, the injection time of a fixed amount of additive at constant pressure varies depending on the viscosity, therefore the temperature of this additive.
