Definitions

  • the present invention relates to an automatic adjustment method and devices for internal combustion engines using polyfuels.
  • the essential object of the present invention is to meet these various requirements.
  • a device for implementing the invention comprises a data processing member associated with the engine and connected to means for detecting operating parameters of this engine and to means for adjusting this operation. It is characterized in that said automatic data processing device comprises means for entering data external to the engine suitable for recording the quantity and characteristics of a fuel supplying the engine supply tank, and in that said automatic data processing device is suitable for producing adjustment signals for engine operating control devices from said data concerning the quantity and characteristics of the fuel supplying the tank, as well as the quantity and characteristics of the fuel previously contained in the tank.
  • the characteristics of the fuel (liquid or liquefied gas) taken into account may be, in particular, its composition (petrol / alcohol or liquefied gas ratio), the stoichiometric air-fuel ratio, characteristic of this fuel, its density, its index octane ... etc ...
  • the invention also relates to the combination of a fuel distribution system for motor vehicles and an automatic data processing device fitted to these vehicles, characterized in that said distribution system is equipped with means delivering data concerning the quantity and the characteristics of the fuel supplying each vehicle in a form suitable for being read by means of introducing said data into said data processing device, and in that the latter is suitable for producing adjustment signals for the control devices of the operation of the engine from said data concerning the volume and characteristics of the fuel supplying the vehicle.
  • the reference M designates a motor supplied with fuel from the tank 1 through the pipe 2, on which the solenoid valve 3 is placed, making it possible to adjust fuel flow.
  • the fuel level in the tank 1 is measured by the gauge 4.
  • the air supply is carried out from the air filter 5 by a pipe 6 passing through a heater 7 and on which is placed a solenoid valve 8 allowing adjust the air flow.
  • This flow rate is measured by the sensor 9.
  • Other sensors 10 and 11 cooperating with a flywheel 12 driven in rotation by the engine respectively determine the engine rotation speed and the passage of the piston at top dead center in each cylinder at each cycle -engine.
  • a combustion sensor 13 determines the abnormal combustion cycles in which the rattling phenomenon occurs.
  • a probe 14 placed on the exhaust gases determines whether these gases come from the combustion of a stoichiometric mixture, fuel / air.
  • the automatic data processing unit (Calc) can be adapted to automatically adjust the ignition advance to an optimal value avoiding the appearance of rattling, as a function of the signals received, in particular, of the sensors 10, 11 and 13, for example according to the method described in US-A-4,120,272.
  • the automatic data processing unit (Calc) is connected to data input means external to the engine comprising the quantity and the characteristics of the fuel supplying the tank 1, this data being introduced at each new refueling of this tank.
  • These data entry means designated by the letter L in Figure 1 may be constituted by a device for reading data carriers such as cards or magnetic strips delivered by the fuel pump at each refueling (magnetic card 17 in the figure 1) and on which are recorded in particular the volume and the characteristics of the fuel supplying the tank 1, in particular its density, its volume and the stoichiometric air / fuel ratio which characterizes it, or the volumetric ratio of two or more constituents of this fuel , such as gasoline and alcohol.
  • data carriers such as cards or magnetic strips delivered by the fuel pump at each refueling (magnetic card 17 in the figure 1) and on which are recorded in particular the volume and the characteristics of the fuel supplying the tank 1, in particular its density, its volume and the stoichiometric air / fuel ratio which characterizes it, or the volumetric ratio of two or more constituents of this fuel , such as gasoline and alcohol.
  • a manually controlled keyboard 18 can be connected to the data processing unit (Calc) in parallel with the reading unit L, by means of an OR gate indicated by the reference 19, to compensate for any failure of the L system for automatic data entry, allowing manual entry of data into the processing unit (Calc) when the tank 1 is refueled.
  • the automatic data processing unit (Calc) may also include circuits for entering data relating to the R settings, this data being for example established during engine bench tests.
  • the device fitted to each vehicle then includes an on-board computer fitted with a magnetic card or magnetic stripe reader coupled with a manual keyboard for entering data.
  • Data will be entered automatically, preferably by magnetic card containing the vehicle's anti-pass code.
  • the anti-theft code In the event of loss of the magnetic card, the anti-theft code must be entered manually at 18.
  • a bypass button on the pump control system can nevertheless allow filling of the tank and distribution of a magnetic ticket 17, to be inserted into the on-board reader L.
  • the user In the event of pumps not yet equipped with these systems, the user will manually enter the volume and the code of the type of fuel displayed at the pump in the on-board computer , the rest of the operations being carried out as above.
  • the automatic data processing unit (Calc) can be adapted to determine, after each refueling, the values (A / F) 3 , V 3 and D 3 of the resulting mixture 3 on the basis of the three relationships (1), ( 2) and (3) above from the initial values (A / F) i , V i and D i and the values (A / F) 2 , V 2 and D 2 characterizing the refueling carried out, these values being plotted on the magnetic card 17.
  • the data processing unit (Calc) will be informed (by transmission of a signal from the sensor 4) each time the tank 1 is filled at 100%, and will then automatically correct it if necessary.
  • the member (Calc) delivers electrical signals for adjusting the solenoid valves 3 and 8 controlling the fuel flow and the air flow respectively, in order to adapt the ratio of these debits to the new value (A / F) 3 .
