AUTOMATIC CONTROL SYSTEM OF CARBURETOR ENGINE OPERATION IN DYNAMIC MODE OF INDEPENDENT IDLING Russian patent published in 2019 - IPC F02D41/02 F02D41/16 F02M3/00 

FIELD: engine building.

SUBSTANCE: invention can be used in carburizing internal combustion engines. System for automatic control of carburetor engine operation in independent idle dynamic mode comprises automobile carburetor engine (1), high-speed mode selector in the form of accelerator pedal (2), actuating mechanism in the form of electromagnetic or electro-pneumatic valve (3), electronic control unit (4), switch (9) and DC source (10) with voltage of 12 V. Electromagnetic or electro-pneumatic valve is arranged in output channel of carburetor idling system. Electronic control unit is electrically connected to the crankshaft rotation speed sensors (5) of the engine, the position of the speed setting device (6), the clutch pedal position (7) and the neutral position of the car gearshift lever (8). Electronic control unit consists of voltage stabilizer (11), amplifier-shaper (12) of high-voltage pulses with value of 4.5 V and low level of 0.5 V, monostable multivibrator Schmid trigger (13), microcontroller (14). Voltage stabilizer converts input supply voltage of 12 V into output voltage of 5 V to supply electric circuits of radio components of unit. Monostable multivibrator Schmid trigger generates rectangular voltage pulses at the output with definite duration and pause between them. Microcontroller is electrically connected with electromagnetic or electropneumatic valve.

EFFECT: technical result is broader functional capabilities of the system.
