A fuel regulator for two-cycle and/or four-cycle internal combustion engines, particularly those found in model airplanes, comprises a microprocessor, a thermocouple exhaust gas temperature sensor, and a fuel regulating valve installed in a low-pressure fuel delivery system between the fuel tank and the carburetor. During operation, the microprocessor continually receives signals from the exhaust gas temperature sensor. These signals are compared with stored temperature ranges to determine the optimum fuel mixture for the current engine operating conditions. If the current engine operating conditions require a variation in the fuel mixture setting, the microprocessor adjusts the degree of opening of the in-line fuel regulating value, and accordingly regulates the flow of fuel into the carburetor.

1. For use in combination with an internal combustion engine having an fuel supply system, a throttle, an exhaust system, and a fuel regulator for the engine, comprising:a plurality of sensors configured to generate signals indicating the operating condition of said engine, at least one of said signals being indicative of exhaust gas temperature; a control valve in the fuel supply system, said control valve regulating the flow of fuel through the fuel system; and a control unit for controlling operations of the engine at all times and speeds, said control unit receiving said signals, said control unit actuating said control valve in response to said received signals, said control unit continually without intermission readjusting the flow settings based on said signals, thereby attempting to achieve optimal performance for said internal combustion engine for any operating condition thereof during the entire time of engine operation.
