The purpose of the invention is to increase the speed of the device in emergency situations of transport means.

The drawing shows a diagram of the proposed device.

The device contains a iiiai-new electric motor (111D) 1 associated with a fuel supply metering authority 2 (fuel pump rail - PTH), electric drive 3 of a HiaroBoro engine, the output of which is connected to the sensor input 4 11tak) P1e1 () nanografi, ycTpoiicTBO 5 adjusting the speed of the SM on one niaioBOM displacement, the input of which is connected to the output of sensor 4, is powered on by the device. The output of the sensor H of the organ for setting the fuel consumption is connected to the input of the key device 7, the nerve output of which is connected to the first input of the additional comparison unit 8, and the BTopoit output to the input of the first memory block 9, the second memory block 10, block 1 1 with three inputs, which are connected respectively to the output of the SM speed control device 5 in one step movement, to the output of the first memory block 9 and to the input of the second memory block K), and the output is connected to the input of the SM control unit 12, the first output of which connected to the course of the second block K) to us, and the second B1.1X () D - to e. 1 niaroBoi electric shock 3, sensor 13, position opi aHa 2, fuel metering, the output of which is connected to the second input of the battery) b.yuka 8 of comparison, and lenepaTop 14 pulses, the input of which (31H) is connected with B1) the input of the donor block 8 is compared, and the output is connected to the electric peep 3 niaroBoro of the engine 1. Electric circuit 3 niaroBoro of the 1П1 engine comes from the electric1 | ICE network ..

The device for motor control in the case of HHei o C1 () transunortal injury is as follows.

When neither the DV operation mode is changed (the transport means (change the position of the or- ganization of fuel consumption) signal, but the flow rate is from the B1 of the sensor input () through the key ycTpoi icTBO 7 and is input to the f) input () of memory block 9, where and there is a CIO memorization. In the exec case (i.e., when) the key ycTpoiicTBo 7 with its second B1) 1x () house is connected to the nepBoio input of block 9 of us gi. The power supply of the Glit electric line 3 111/1 1 is measured at the same time. This means that the sensor of the first 4 sensors is fed to the input of the device for controlling the speed of the SD in one movement. Depending on the magnitude of 1 1 signal I, the device 1 (station 5 is outputted to the first input of block II with a signal. V.: 1 Jun.1 and 11 tpe1339282

the buoy speed of movement of the rotor SM 1 on one step move.

The memory of the second memory block 10 stores information on the fuel supply of the previous operating mode of the two transport means. The second input of the comparator unit 11 receives the signal Z (required fuel supply) from the output of the first memory unit 9, and the third input of the comparator unit 11 receives the signal Z, from the output of the memory unit 10. (fuel supply of the previous steady state operation of the engine). In block 11 of the comparison, the signals Z and Z are compared and the result of this comparison (signal AZ) from the output of the block

11 comparison enters the input unit 12 controls the SM. The comparison of the signals Z, and Zj occurs every time when the first input of the comparator 11 receives the signal V from the output of the device 5 pa.

Depending on the size of the signal DZ, from the second output of the SM control unit 12, the driving pulses of the required shape and duration are rotated into the electric stump 3 of the stepping motor 1 in one direction per Hiar with the required speed (.) To rotate the rotor 1 and Д 1. At the same time, from the first output of the control unit 12111D to the input BTopoi o of the memory block K), the compiler Z arrives, increasing the contents of the memory of the second memory unit 10 by one.

In the case of the second output unit

12S71 shreddings into the HiaroBoro electric circuit 3 of the engine 1 receive the driving pulses of the required form and duration for turning the rotor of the SM 1 in the opposite direction of one tag at the required speed. At the same time, the signal AZ, which arrives from the first output of the SM control unit 12 and the input to the second memory block 10, reduces the memory contents by one. The fuel metering unit 2 (fuel rail 1x pumps) associated with the rotor 1 and D 1 increases (or decreases) the supply of fuel to the cylinders of the internal combustion engine. Regulation of fuel iodachi occurs to the moment Z, Z.

With a sudden failure of the organ to set the fuel consumption to the zero (n) position, if an emergency stop is needed) at the output of the sensor (i but is signal Z ,. At the same time, the key device 7 connects the output of the sensor Ci with the nerve output to B. Yuka 8. Comparison. C. The output of the sensor 6 is signal. I Zo through the additional unit 8 of the comparison enters the input of the generator 14 name. ibcoB and starts eix). The generator 14 pulses start to generate electrical impulses of the required shape and duration in e. 1ektrichesky chain 3 SMD frequency, ensuring the occurrence of uiai4) Boro engine 1 in synchronism without slip, i.e. The rotor of the SM 1 starts to rotate synchronously with the change of the electromagnetic field in the working gap, and not discretely. Thereby, the time of permutation of the organ 2 for metering the fuel supply to zero fuel delivery is minimized. From the output of the PTH position sensor 13, the signal ZP about the actual position of the PTH is fed to the second input of the additional comparison unit 8, 1 de compares with the signal Ze.

If there is a mismatch from the output of the additional comparison unit 8 to the input of the generator 14: 1 i s passes the iZp signal, and thus the pulse generator 14 continues to send electrical pulses to the electric stump 3 W / 1, causing synchronous (continuous) rotation of the rotor SM 1, and, therefore, continuous (not discrete) reduction of fuel supply by org 2 of dosing of fuel supply.

In the absence of a mismatch (Zp Zj) from the output of the additional comparison unit 8, the signal is not received at the input of the generator of 14 pulses, so. 0, and the pulse generator is turned off. The rotor of the stepping motor 1 stops, the rail of the fuel pumps two is set to zero fuel supply. Thus, the absence of a mismatch signal on the course of the additional comparison unit 8 indicates that the fuel in the engine pilins is not iodine.

The use of the proposed device in comparison with the known one allows to increase its speed by minimizing the reuse time of the fuel metering body to zero fuel delivery while dramatically moving the body to set the fuel consumption to zero and thereby improving vehicle safety.
