Abstract

PURPOSE:To make it possible to rotate the engine at a predetermined speed irrespective of the variation of an engine load during idling by a method wherein when an accelerator pedal is released, a control circuit drives a motor in response to the signal from each of parameter sensers and the opening degree of a throttle valve is controlled through a worm gear. CONSTITUTION:When the accelerator pedal is released from the foot of the driver and a throttle lever strikes a stopper pin 17 to cause the left end surface of the pin to come into contact with an electrode 11, cables 1-2 and 1-3 are held conductive so that an electronic control circuit 1 begins to operate. Thus, when the negative pressure of air intake increases excessively to allow an excessive fuel to be supplied from the slow system of the engine, the control circuit 1 rotates the control motor 2 in a direction in which a male screw 10 advances to the left so that the throttle valve is closed completely to thereby interrupt the fuel supplied from the slow system in response to the signal from a negative pressure sensor or a rotation sensor. Further, the output signals from the various kinds of operation parameter sensors rotate the motor 2 clockwise or counter-clockwise so that the opening degree of the throttle valve is controlled through the pin 17 to cause the engine to operate at a predetermined idling speed.

。When operating equipment that requires an increase in idling rotation speed, such as when operating an air conditioner compressor, the idling rotation speed can be increased by an on signal from the electric circuit of the equipment. During deceleration, when the accelerator pedal is released and the throttle valve is suddenly closed, the throttle valve is completely closed by the negative pressure signal generated in the intake system 1 or the signal from the rotation sensor. It is possible to cut off the fuel supply,
Also, when the key switch is turned OFF, the power supply is cut off by the action of the delay circuit, and then the throttle valve can be fully closed. The circuit relates to a mechanical control mechanism including a control motor that performs forward and reverse rotation based on output signals generated by inputting and calculating the various signals described above.The features and value of the present invention are explained below based on the attached drawings. This will become clear from the description of the invention effect in the explanation pot.

して過剰燃料がスロー系から供給される様なときには。When the engine is operated by the driver, that is, when the accelerator pedal is depressed, the throttle valve lever is not in contact with the throttle stopper pin 17, so the throttle stopper pin 170 is The left end surface is away from the end surface of the electrode body 11, and the connection between cables 1-2 and 1-3 is broken. In this state, the electronic control circuit 1 is not operating at all. In this state, the position of the male threaded body IO has nothing to do with the operating state of the engine (...Next, the driver releases his or her foot from the accelerator pedal, the throttle lever hits the throttle stopper pin 17, and the throttle return spring forces the throttle stopper. When the left end surface of the bottle 17 comes into contact with the end surface of the electrode body 11, conduction is established between the cables 1-2 and 1-3, and the electronic control circuit starts operating. When the engine intake negative pressure increases significantly and excess fuel is supplied from the slow system.

度を設定したアイドリンク速度となる様に制御する。The electronic control circuit rotates the control motor 2 in the direction in which the male threaded body 10 moves to the left in the figure, and the throttle valve completely closes and slows down. After cutting off the fuel in the system, input signals from various operating parameter sensors of the engine are calculated, and the output signals give forward and reverse rotation to the control motor and set the throttle valve opening degree via the throttle stopper bin 17. The idle link speed is controlled so as to achieve the specified idle link speed.

２３の中に後退することができる。In order to control the opening degree of the throttle valve according to engine operating parameters, the opening degree is increased or decreased with respect to the reference opening degree, so it is necessary to determine the reference opening degree. The reference opening degree is adjusted so that the left end of the electrode body 11 in FIG. 9 comes into contact with the sphere built in the screw body 23 at the rotational speed set under standard idling operating conditions. Since the screw body 23 is connected to the cable 1-4, the above contact is between the cable 1-3 and the cable 1-4.
It becomes conductive with. □For example, if the temperature of the machine / machine / machine rises above the standard temperature and the 1 rotation speed tends to increase, the control circuit 1 inputs the signal from the temperature sensor or the signal from the rotation sensor. A signal in the direction of closing the throttle valve opening is given to the control motor 2. The sphere 23-1, which is the electrical contact of the screw body 23, is connected to the coil spring 23-
2, it can follow the electrode body 11 and retreat into the screw body 23.

and the electrode body 11 is separated.

It is also possible to provide a function to cut off slow type fuel.

A hollow male threaded body 10. which moves in the direction of the center line of the rotational axis of the worm gear 9 by threading anastomosis with the worm gear 9. An electrode body which is electrically insulated and fixed to the hollow male threaded body IO on one end side of the hollow part of the hollow male threaded body 1/0, and whose outer end side protrudes from the hollow part]1. It is slidably fitted into the other end of the hollow part and is urged by a spring 18 in a direction away from the inner end surface of the electrode body 11, so that it comes into contact with the inner end surface of the electrode body 11 when the accelerator pedal of the surrounding vehicle is released. Consists of a throttle stopper pin 17° constituting an electrical contact and a screw body 23 disposed facing the outer end protrusion 11-1 of the electrode body 11 and constituting a switch mechanism for determining the reference opening of the throttle valve. and the control electric motor 2. Worm 6, worm gear 9. A hollow male threaded body IO and a threaded body 23 constituting a switch mechanism for determining the reference opening of the throttle valve are assembled in the casings 4 and 5 made of an electrically insulating material, and the hollow male threaded body IO]0. Electrode body 11. and a screw body 23 constituting a switch mechanism for determining the reference opening of the throttle valve, which is electrically connected to the electronic control circuit l (2). The screw body 23 constituting the switch mechanism has a thread on its outer peripheral surface, and the spherical body 23-1 constituting the electrical contact is connected to the coil 23-
The idle link speed control device for an engine according to Claim No. 11 (3), which comprises a cylindrical body with a bottom that can be elastically retracted by the hollow male screw body 10 and the electrode body 11, respectively. Electronic control circuit 1 via coil springs 19 and 20
