ELECTRONIC CONTROLLER OF SPEED OF ROTATION FOR CONTROLLING FUEL SUPPLY BY HIGH-PRESSURE FUEL PUMP Russian patent published in 1996 - IPC

FIELD: engine engineering. SUBSTANCE: electronic controller has load governor 1 whose core 2 coupled with either pedal 3 (car version) or pedal 3 and handle 4 (tractor version) for controlling fuel supply has shorted one-layered winding 5. The width of the layer of winding 5 can varies and is defined by the stroke of pedal 3 or handle 4. In addition the load governor has two multi- layered windings-coils. One of the them is short measuring winding 6 and is 5 mm in length. The other is long exciting winding 7 whose width corresponds to the stroke of the core. Exciting winding 7 is energized with sinusoidal voltage. Depending on a position of shorted core 2 in long winding 7 currents of different amplitudes were induced in core 2 causing different voltages at measuring winding 6. The signal proportional to displacement of core 2 is fed to the electronic portion of the controller from measuring winding 6. EFFECT: enhanced reliability. 2 cl, 2 dwg
