The control of fuel injection amount and injection timing, which was previously controlled mechanically, is now being focused on electronically controlled gantry, which uses microcomputer control to precisely control the amount and timing of fuel injection according to each operating condition. In particular, the electronically controlled governor that controls the fuel injection amount is, for example, a Bosch distributed injection pump, as shown in FIG. An engine rotation sensor 4 is provided on the accelerator pedal 5, and an accelerator position sensor 6 is provided on the accelerator pedal 5. Signals obtained from these sensors are input to a control unit 7 from a microcomputer, etc. The actuator 8 is operated in response to a command, and the injection amount adjustment sleeve 9 (spill ring) is moved to control the fuel injection amount according to each driving situation. When the spill ring 9 moves to one side, the injection amount increases and its upper limit determines the maximum injection amount, and when it moves to the other side, the injection amount decreases and its lower limit becomes the idle rotation state. Therefore, without having to perform the spill ring 9 mechanically, the injection amount can be obtained according to each driving condition based on the data set by the signals of each sensor, and the power, fuel consumption, and fuel efficiency can be improved. It's starting to get hot.

Incidentally, in addition to the above-mentioned driving conditions, the weight of the vehicle is also a major factor that determines the power characteristics of the vehicle. Conventionally, since the driving force of a vehicle is proportional to the maximum injection amount, the upper limit position of the spill ring 9 has been set at the engine adjustment stage so as to be commensurate with the total vehicle weight.

However, although it is possible to freely set the upper limit position of the spill ring 9, which determines the maximum injection amount, once it is set, it is a fixed type that cannot be moved unless it is adjustable, so if the weight condition matches the set value. However, since the maximum injection amount is determined regardless of the size of the cargo, there is a possibility that there will be a surplus of driving force, and in this case, the disadvantage is that the fuel consumption will deteriorate because the vehicle will be accelerated more than necessary. was there.

Nowadays, the amount of luggage loaded on vehicles increases, and the weight of the loaded vehicle increases, and the standard value is W. If the condition exceeds WI, the strain gauge 17 attached to the vehicle frame 16 will immediately detect this.
The detection signal O is sent to the controller I roll unit l-12. Arithmetic unit 1 provided in control unit 12
9 receives the detection signal C described in 1- and corrects the full rack position corresponding to the weight of the loaded vehicle from XO to X+. At the same time, as shown in FIG. 4, the amount of change in movement of the injection amount adjustment rack 14 per stroke of the accelerator pedal is corrected to match the corrected full rack position XIK, and the full rack position X is set. The amount of movement of the injection amount adjustment rack 14 is increased compared to when the injection amount adjustment rack 14 was used. The above modification is necessary because the full stroke of the accelerator pedal is constant and cannot be changed.

Through such control, the maximum fuel injection amount for each mode increases, and the fuel injection amount over the entire stroke length of the accelerator pedal also increases uniformly, so that the fuel injection amount is equal to or higher than the standard value Wo and the loaded vehicle weight W is increased. It was worth it. Driving force can be obtained and there will be no lack of acceleration or stalling.

Similarly, if the weight of the loaded vehicle decreases to W2, the full rack position of the injection amount adjustment rack 14 is corrected to X, and the amount of movement of the injection amount adjustment rack 14 is corrected in the direction of decreasing. In the case of W, 2, the value of X2 can also be entered in all rack positions above rack position X2. With this control, it is possible to obtain one driving force that is less than the standard value Wo and that is commensurate with the loaded vehicle weight W2, and there is no surplus in one driving force and there is no need to accelerate the vehicle more than necessary.

Therefore, at full load, as shown in FIG. 5, the actual injection amount adjustment rack 14 is controlled directly depending on the weight of the loaded vehicle, that is, the size of the cargo, and the position of the rack increases or decreases.
Since the maximum injection amount increases or decreases, only the necessary driving force can be extracted efficiently, acceleration performance is good, and fuel efficiency can be improved.

As can be seen from FIG. 5, the control according to the present invention is not performed during startup, idling, or maximum speed control. This is because it requires a larger amount of fuel to be injected at startup than the injection amount at full load, so the main order 8b is the sub-unit 4? e
This is because the system gives priority to overcharging.
