METHOD OF CONTROLLING FUEL-AIR COMPOSITION IN CARBURETOR INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: current speed of rotation of the engine shaft is measured and additional fuel is periodically fed to the flowing passage of the carburetor through a valve of fuel pipe. Real current value of the speed of rotation of the engine shaft, which is measured at maximum power, is compared with a given speed of rotation of the shaft, which corresponds to maximum power of the engine for given speed regime of the engine operation and given opening of the throttle gate, which is also measured. When the speed of rotation exceeds the real one the pipe line valve is open to provide additional fuel supply and reaching a required power of the engine. EFFECT: simplified method. 1 dwg
