    A control system for controlling an internal combustion engine which is provided with at least one fuel injection pump which comprises for the control of the fuel injection pump a control rod, a servomotor, which is adapted to be mechanically coupled to said control rod, and a microcomputer for controlling said servomotor in dependence on operating conditions of the engine and on the position of an arbitrarily operable travel control lever. Means are provided for establishing a direct mechanical connection between the arbitrarily operable travel control lever and the control rod so that the latter can be moved under the control of the travel control lever in case of a failure of the electric system which comprises the sensors, the microcomputer and the servomotor.

    This invention relates to mechanical engineering, in particular, to fuel management systems for an internal combustion engine,
    The purpose of the invention is to increase the reliability of control in case of electronic unit failure.
    Fig, 1 shows a diagram of the device in the position of zero fuel supply and disconnected electronic unit; in FIG. 2, the same in the zero-feed position and the electronic unit turned on; in fig. 3 - the same, in the position of maximum fuel supply in the case of control of electrical means; FIG. 4 is the same in the position of maximum fuel supply in the case of controlling mechanical means;
    The device comprises a high pressure fuel pump 1, the regulating element 2 of which is associated with the pump rail 3.
    The rail 3 in the zero-feed position (FIG. 1) is pressed by the spring 4 against the stop 5. A swivel dog 6 is mounted on the rail 3, which is kept in the resting position with the help of the spring (FIGS. 1 and 4). The pawl 6, mounted on the axis 7, has two restrictive stops in the form of bolts 8 and 9, with the bolt 8 forming the first stop shorter than the bolt 9 serving as the second stop. In the case of control by electric means, the rail 3 is moved with the help of a pivoting lever 10, which is held in the rest position by means of the spring 11, which is a setpoint sensor, and the sensor 21, which is installed with the possibility of interaction with the lever 10, provides valid values to the microcomputer 16 . The microcomputer 16 is connected to a power source using a switch 22,
    The angular movement of the lever 15 is limited by an adjustable stop 23. To determine the position of the lever 10, the control device is equipped with a switch 24 installed in the signal lamp circuit 25.
    The device works as follows.
    When the switch 22 is closed, an electric control device is activated, consisting of sensors 17, 20 and 21, a microcomputer 16 and an executive motor 13; the pivot arm 10 with the help of the actuating engine 13 is deflected to the position shown in FIG. 2, in which the rail 3 still occupies the zero fuel supply position, and the pawl 6 tilts upwards with the help of the beveled surface of the lever 10 and the first stop of the pawl-bolt 8, The second stop of the pawl, the bolt 9, is out of the way of turning the lever 15. If the fuel control knob 19 is actuated and the lever 15 is deflected, this causes the displacement of the adjusting level of the executive engine 13, which corresponds to the angle of rotation of the lever aha 15, by reading the position of the lever 15 by means of the sensor 20 and the microcomputer 16, so that
    j2, and deflects from the polo-O, the pivot arm 10 is deflected and
    Rest with the help of an executive engine 13, another pivot arm 15 is mounted on the axis 14 of the arm 10, and the arm 10 is mounted to engage the bolt B of the pawl and the arm 15 is connected with the longer bolt 9,
    The control of the actuating motor 13 is carried out by means of an electronic unit, for example, a microcomputer-Q switch, the possibility of operation is maintained.
    A tera 16 in which various operating parameters of the internal combustion engine are introduced by means of several sensors 17. The lever 15 is connected: through the system tg 18 to the fuel supply control knob 19 jj, the position of the lever 15 being read by means of the sensor 20, which is also connected to the microcomputer 16, the sensor 20
    in emergency mode, because by returning the lever 10 to the rest position, determined by the stop 12, the dog 6 returns to the rest position under the action of the spring, in which the second stop bolt is in the way of the turn of the lever 15, and mk 19 regulating fuel supply to the rail 3
    This, through the first stop, the bolt 8 carries with it the rail 3 from the zero feed position. When this occurs, the movement of regulator link 2 and on. 5 coy 1 delivers the appropriate amount of fuel.
    If the electric control device fails, then with the aid of the supply control knob 19 of the emergency mode, since by returning the lever 10 to the rest position, determined by the stop 12, the pawl 6 returns to the rest position in which the second the stop bolt is on the way of turning the lever 15, and a force closure is created from the fuel control handle 19 to the rail 3
    515
    With the fuel supply adjustment knob 19 completely rejected and the mechanical means controlled, it is impossible to reach the full stroke of the rail 3 and thereby complete cycle supply, because the turning path of the lever 15 is limited by the stop 23. At the rest position of the lever 10, the switch 24 and the light bulb 25 signals the failure of an electronic device.
