Description

258605

BACKGROUND OF THE INVENTION The present invention relates to a wiring for a regulated load control motor. It can be used in vehicles with electric or hydraulic power transmission of the combustion engine to the drive wheels.

[0007] The prior art wiring for control combustion engines associated with electrical or hydraulic transmission utilizing electronic components is complex. Although contactor and magnetic amplifier systems are simple, they have insufficient regulatory properties and low system dynamics.

The above-mentioned disadvantages are eliminated by the connection for controlling the combustion engine with a variable load according to the invention. The interconnection includes one controller, two delay elements, two two-input summator, one two-input summator and one non-linear converter. The advantage is that the output of the non-linear transducer is connected to the first input of the controller and the non-inverting input of the second summator. The input of the non-linear converter is coupled to the output of the first summator. The output of the second summator is coupled to the input of the first delay member, which output is coupled to the inverting input summator. The second non-inverting input of the first summator is coupled to the input of the second delay member, which output is coupled to the non-inverting input of the third summator. The inverting input of the second summator is coupled to the second input of the controller, the output of the controller being coupled to the batch determining the fuel of the combustion engine. The output of the third conductor is connected to the block determining the combustion engine. The second non-inverting input of the first summator is coupled to the blocking of the desired power of the combustion engine, and the first non-inverting input of the first starter is coupled to the auxiliary drive output block and the inverting input of the second summator is coupled to the rotational speed of the combustion engine. Advantages of the solution according to the invention are that, in a simple connection, the regulation of the combustion engine is made possible with optimum mode while maintaining good dynamic properties.

The circuit diagram of the control of the combustion engine that drives the regulated load is shown in Fig. The wiring consists of controller 1, first summator 3, second summator 4, third summator 5, non-linear transducer 2, first delay the member 6, the second delay member 7 and the blocks corresponding to the power drives 18, the desired power 19, the actual speed 20, the combustion engine and the fuel dosage block 21a of the combustion engine 22. The role of controller 1 is to maintain the actual combustion engine speed at the setpoint, which is obtained through a non-linear converter 2 from the set power of the combustion engine. The non-linear transducer 2 includes an optimum transmission characteristic of the combustion engine output in relation to its speed. The set power consists of the power of the auxiliary drives and the required power. The desired output of the combustion engine also proceeds through the second delay member 7, which operates only in the upward direction and the third accumulator 5 and determines the load of the combustion engine. The delay of this signal, i.e. the load increase delay, will allow the combustion engine to acquire more speed faster and prepare for higher power take-off.

In a bad technical condition, when the combustion engine will not be able to maintain the set speed, it will bind the remaining of the second summator 4 and the first delay member 6. In the second dryer 4, a signal was generated corresponding to the difference between the set and the actual turns of the combustion engine and delayed in the first delay member 6 to the third summator 5 with a negative indication and cause a reduction in power consumption. The setting of the constants of the second summator 4, the third summator 5, the first delay member 6 and the second delay member 7 determines the properties of the system in transient modes, whereby, together with the characteristics determined in the nonlinear converter 2, it can be set to the optimal mode combustion engine.

The wiring described can be applied to diesel-engine and electric or hydromechanical transmi- ders, for example in diesel-electric locomotives, heavy vehicles and the like.
