DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be specifically described below based on the embodiments shown in the drawings.

A fuel injection pump for an internal combustion engine, in particular a spark-ignition internal combustion engine, which is shown in a highly simplified manner in FIG. 1, has a pump piston 10, which is provided by means not shown. It is driven so as to perform a reciprocating motion simultaneously with a rotating motion. Pump piston 10
A pump working chamber (not shown) is partitioned by the escape working passage 11 in the pump piston 10 leading from the pump working chamber to the surface of the pump piston 10.
Ring slider 1 arranged as a fuel amount adjusting mechanism
It is covered by 2 or opened. When the pump piston 10 reciprocates, the relief passage 11 is opened early or late depending on the position of the ring slider 12 after a certain stroke, thereby ending the injection. Therefore, the axial position of the ring slider 12 determines the amount of fuel injected.

One arm of a two-arm adjusting lever 15 as an adjusting mechanism is engaged with the ring slider 12 via a ball head 14, and the adjusting lever 15 can pivot about a shaft 17. . On the other arm of the adjusting lever 15, a speed governor 18, which is shown schematically, acts with a speed-related force, which speed governor is designed especially as a centrifugal speed governor. Driven in synchronization with. Further, a speed control spring 20 and an idling spring device 21 act on the other arm of the adjusting lever 15.

The adjusting lever 15 has a hole in its end region, through which the pin 23 is guided. The pin 23 has a head 29 at one end thereof, and an adjusting spring 30 configured as a pressing spring is arranged between the head 23 and the adjusting lever 15. The adjusting spring 30 has an Angleich function for adjusting the adjusted fuel injection amount in relation to the rotational speed. The speed control spring 20 acts on the other end of the pin 23 via a spring receiver 24. The speed control spring 20 is configured as a push spring,
4 is fastened between the connecting member 26 and the connecting member 26, which is connected via an eccentric disc or lever arm to an adjusting lever 27 arranged outside the fuel injection pump. Useful for adjusting the fuel injection amount. The speed control spring 20 can also be configured as a tension spring.
The tightened speed control spring 20 acts against the adjustment of the adjusting lever 15 by the force related to the speed of the speed governor to increase the injection amount, and when the final speed is reached, the injection amount is increased. Compressed to reduce. In the case of full load adjustment, the adjusting lever 15 is in contact with the stop 32, either by the action of the speed control spring 20 or by a corresponding adjustment of the adjusting lever 27. The stopper 32 is a two-arm full load adjusting lever 3
3 is formed on one end of the lever arm.

The full load adjusting lever 33 is rotatably supported on a stationary shaft 35, and an adjusting member 36 of an adjusting motor 38 is provided at the other lever arm end of the full load adjusting lever 33.
Are engaged. The adjusting motor 38 is in this case configured as a linear motor, but it can also be configured as a rotary motor to rotate the adjusting member 36. The adjusting member 36 is configured as a rod, through which a lateral pin 37 penetrates and engages the full load adjusting lever 33 in a direction of adjusting the stopper 32 so as to increase the full load injection amount. A return spring 42 is tightened between the full load adjusting lever 33 and an immovable member, for example, a casing 41 of the adjusting motor 38. The return spring 42 reduces the full load injection amount and reduces the full load adjusting lever 33. And has a larger initial spring force than that of the governor spring 20. A spring bearing 44 having a predetermined thickness is arranged between the return spring 42 and the full load adjusting lever 33, and this spring bearing moves the full load adjusting lever 33 in a direction to increase the full load injection amount. Helps limit the distance. In this case, the full load adjusting lever 33 is supported by the casing 41 via the spring bearing 44. Therefore, by properly selecting the thickness of the spring receiver 44, the maximum full load injection amount can be limited to an allowable value. In addition, the spring bearing 44 serves as a starting stop for the adjusting motor 38, so that each time the fuel injection pump is started, the adjusting member 36 is supported by the casing 41 via the spring bearing 44, for the subsequent adjustment of the adjusting motor 38. A fixed starting position will be given. The movement of the full load adjusting lever 33 is restricted by the stopper 45 in the direction of decreasing the full load injection amount. This stopper 45 is in particular constructed as an eccentric disc which is adjustably mounted on the casing of the fuel injection pump. The adjusting motor 38 is designed in particular as a stepper motor and is operated by a control device 39 which is only shown schematically. Control device 39
Inside, various operating parameters of the internal combustion engine operated by the fuel injection pump, such as load, temperature and boost pressure, are processed. By means of the control device 39, the full-load adjusting lever is brought into a position corresponding to the maximum full-load injection quantity that can be tolerated under the actual operating parameters of the internal combustion engine.

The idling spring device 21 is attached to the adjusting lever 1
In order to connect with 5, the adjusting lever has another hole through which a pin 47 is guided, on which the idling spring device 21 acts. The idling spring device 21 consists of two initially spring-loaded push springs 49, 50, which are fixed in the region of the end of the pin 47 on the side opposite the adjusting lever 15. It is supported by a spring receiver 52 and a collar of a support member 53 configured as a sleeve. Pin 4
7 is movable in the support member 53 together with the spring receiver 52. The push spring 50 is supported by a spring bearing 52 and possibly also via a spring bearing on one lever arm end of a two-arm idling adjustment lever 55. The end of the lever arm of the idling adjustment lever 55 is formed in a fork shape and holds the pin 47. The pin 47 penetrates the hole of the holder 48 fixed to the adjusting lever 15, and is supported by the head 51 on the side of the holder 48 opposite to the idling spring device 21. In this case, the head 5 of the pin 47 acting on the adjusting lever 15 is pushed by the push spring (idling spring) 49.
Via 1, the adjusting lever 15 is pulled against the governor 18. In this case, the initial spring force of both push springs 49, 50 acts on the spring receiver 52, and thus on the adjusting lever 15 via the pin 47. The idle adjusting lever 55 is pivotally supported on the same shaft 35 as the full load adjusting lever 33. The adjusting member 36 of the adjusting motor 38 acts on the other end of the lever arm of the idling adjusting lever 55. A return spring 58 is tightened between the idling adjustment lever 55 and the fuel injection pump casing 56, and the return spring 58 is used by this return spring.
Is loaded in a direction opposite to the direction of adjustment by the adjusting motor 38. In this case, the return spring 58 has a larger initial spring force than the push spring 50. The movement of the idling adjusting lever 55 is limited in the direction opposite to the direction of adjustment by the adjusting motor 38 by means of a stop, which is in particular the same member as the stopper 45 for the full load adjusting lever 33, but of this member. It is formed on the opposite side.
No stopper is provided to limit the movement of the idling adjusting lever in the adjusting direction of the adjusting motor 38. If an immovable stopper is provided for this purpose, the adjusting motor 38 pushes the idling adjusting lever 55 against the immovable stopper, causing a malfunction of the adjusting motor 38 when the adjusting member 36 can no longer move in the adjusting direction. Sometimes. The use of a stepper motor makes it possible, for example, to provide in the control unit a maximum number of steps that the stepper motor must not exceed, which ensures that the idle adjusting lever 55 is separated from the pump casing. can do.

When the idling adjusting lever 55 is adjusted by the adjusting motor 38, one supporting point of the push spring (idling spring) 50 is adjusted. Adjustment motor 3
8, the idling injection amount can be reduced from the amount determined by the stopper 45. In this case, the adjusting member 36 of the adjusting motor 38 moves the idling adjusting lever 55 against the force of the return spring 58. In this case, the supporting point of the push spring (idling spring) 50 is adjusted in the direction to reduce the spring force, the force acting on the adjusting lever 15 via the pin 47 is reduced, and the adjusting lever is adjusted by the speed governor 18. It In this case, ring slider 1
2 is adjusted to decrease the fuel injection amount. By means of a control device which operates the adjusting motor 38, the idling injection quantity can be adjusted as a function of operating parameters in order to maintain a constant idling speed of the internal combustion engine. For example, when operating additional equipment such as air conditioning compressor / lighting equipment or cooler blower,
The amount of idling injection required to achieve stable idling is large. If the additional equipment is not operated, the adjusting motor 38 can correspondingly reduce the idling injection quantity.

The supporting member (sleeve) 53 of the idling spring device 21 is axially displaceable from the outside of the casing of the fuel injection pump and is supported for this purpose, for example on an eccentric disc, for idling. The basic adjustment of the fuel injection amount of is possible. When the support member (sleeve) 53 is adjusted, the support point of the push spring 49 is adjusted relative to the spring receiver 52, and the spring force of the push spring 49 is changed. In this case, the pin 47 moves when the other force is unchanged, whereby the position of the adjusting lever 15 is changed, and the adjusting lever is moved by the speed governor 1.
The force of 8 and the force of a push spring (idling spring) 49 changed at the time of adjustment are used for turning. In this case, the adjustment lever 15 is engaged with the ring slider 12, so that the fuel injection amount is changed. In this case, when the spring force of the push spring (idling spring) 49 is increased, the idling injection amount is increased, and conversely, when the spring force is decreased, the idling injection amount is decreased. In the case of the basic adjustment of the idling injection amount described above, the position of the idling adjustment lever 55 does not change with respect to the casing of the fuel injection pump. The lever arm of the idling adjustment lever 55 acting on the push spring 50 limits the movement of the pin 47 in the direction of reducing the fuel injection amount of idling.

At the time of starting the internal combustion engine, no force is exerted on the adjusting lever 15 by the speed governor 18. Therefore, the adjusting lever 15 is stopped by the adjusting spring 20 and the pressing spring (idling spring) 49 acting on the adjusting lever 15.
Be attracted to. In this case, the full load adjusting lever 33 is adjusted by the adjusting motor 38 in relation to the temperature of the internal combustion engine, and the required amount of starting fuel is adjusted each time. The adjusting mechanism of the fuel injection pump is therefore particularly simple, since no starting spring and / or starting lever is required for controlling the starting fuel quantity, only the adjusting lever 15 is required. During idling operation of the internal combustion engine, the speed control spring 20 is compressed in the direction of the minimum fuel injection amount, the adjusting lever 15 is separated from the full load stopper 32, and the adjusting lever 15 is connected via the pin 47. It is only loaded by a push spring (idling spring) 49 acting on. In this case, the idle adjustment lever 55 is moved by the adjusting member 36 of the adjusting motor 38 to the position shown in FIG. The full load adjusting lever 33, which no longer follows the adjusting member 36, is pressed against the stopper 45 by the return spring 42, so that the full load injection quantity is limited to a minimum value. This adjustment of the full load adjusting lever 33 is also realized in the case of an emergency operation in which the adjusting motor 38 fails in the idling position and no adjustment is made. This prevents excessive fuel injection and a smoke shock when transitioning from idling to full load operation via partial load operation with corresponding adjustment of the adjusting lever 27 and speed control spring 20. When the full load injection amount is controlled by the adjusting motor 38 during load operation,
The adjusting member 36 is moved to the right from the position shown in FIG. 1, which also moves the full load adjusting lever 33 to the right. In this case, the idling adjusting lever 55 is pressed against the stopper 45 by the return spring 58, and the maximum fuel injection amount for idling is adjusted. This guarantees a soft transition to idling.

The adjusting lever 15 can be mounted on the adjusting lever 60 via a shaft 17. Adjustment lever 60
Is rotatably supported on a stationary shaft 61, in this case pressed against an adjusting screw 64 by a spring 63,
The adjusting screw 64 can be operated from outside the pump casing.

In the variant shown in FIG. 2, a starting lever is additionally provided. In this case, ring slider 1
A starting lever 66 is connected to the shaft 2. The starting lever can be swung around a stationary shaft 67, and the speed governor 18 acts on the starting lever. The adjusting lever 15 is also mounted so as to be pivotable about a shaft 67, in which case the speed control spring 20 acts on this adjusting lever 15 and the idling spring device 21 acts on the starting lever 66.

The adjusting lever 15 is provided with an arm 69 facing the speed governor 18, which has a pin 70 extending transversely to the direction of rotation of the starting lever 66,
This pin 70 projects into the movement path of the starting lever 66. The pin 70 forms a stop for the starting lever 66, which cannot be separated too far from the adjusting lever. As a result, the maximum fuel injection amount when starting the internal combustion engine is limited.

When starting a low temperature internal combustion engine, the maximum amount of fuel is injected. In this case, the adjusting lever 15 is pin 2
It is pressed against the stopper 32 formed by the lever arm of the full load adjusting lever 33 via the head 29 of No. 3, and is in the full load position. The full load adjusting lever 33 is brought to a position of maximum fuel injection amount by an adjusting motor 38. As soon as the speed governor 18 starts rotating,
Starting lever 6 on which the idling spring device 21 operates
Engage 6 The speed governor 18 operates at a small number of revolutions,
The starting lever 66 is moved towards the adjusting lever 15.

When the warmed internal combustion engine is started, the adjusting motor 38 controls the adjusting lever 15 via the full load adjusting lever 33 in the direction away from the speed governor 18.
The starting lever 66 is pulled toward the pin 70 of the adjusting lever 15 by the idling spring device 21. Pin 70
Forms a stopper for increasing the fuel amount at the time of starting. That is, the pin 70 is adjusted via the adjusting lever 15 and the stop 32 which is brought from the maximum full load adjustment amount adjustment position to the small full load adjustment amount adjustment position in the case of a low temperature internal combustion engine. It The adjustment of the temperature-dependent stopper 32 via the adjusting motor 38 produces a temperature-related starting fuel quantity at the start of the warmed-up internal combustion engine, which fuel quantity is supplied to the idling spring device 21 quickly after starting. It can be reduced against. Therefore, in the case of starting the internal combustion engine which is warmed up, the fuel increase is controlled via the pin 70 of the adjusting lever 15 in relation to the temperature of the internal combustion engine.

During the idling operation of the internal combustion engine, the starting lever 66 is not in contact with the pin 70 or the adjusting lever 15. In this case, the position of the starting lever depends on the force of the idling spring device 21 acting on it and the governor. It is determined by the balance with the power of 18. Idling spring device 21
The force exerted on the starting lever 66 by means of the pin 47 is changed by the adjusting motor 38 via the idling adjusting lever 55, as in the embodiment shown in FIG.

During load operation, the starter lever 66 moves the governor 1
8, the adjusting spring 15 on which the speed controlling spring 20 is operating
Pressed against. In this case, governor spring 20 and governor 1
The balance of forces between 8 and 8 determines the position of the adjusting lever 15 and the starting lever 66. In the fully loaded position, the adjusting lever 15 is in contact with the stop 32 whose position is determined by the adjusting motor 38. In the case of deceleration control,
The adjusting lever 15 is separated from the stopper 32 by the speed governor 18 via the starting lever 66 in the direction of reducing the fuel injection amount against the force of the speed controlling spring 20.

In order to be able to selectively implement the idling injection quantity control or the full load injection quantity control, the control device 39 must be supplied with information about the operating state of the internal combustion engine. For this purpose, a transmitter 28 is provided which is operated by the adjusting lever 27. As the transmitter 28, for example, a potentiometer adjusted by the adjusting lever 27 can be used. It is also possible to limit the adjustment distance of the adjusting lever 27 by the idling stopper and the full load stopper, and to equip both stoppers with limit switches operated by the adjusting lever 27 as transmitters.
