Latest Patents

Isobe holds a patent for a system titled "Coarse and fine air supply control for closed-loop controlled carbureted." This invention focuses on a closed-loop air-fuel mixture control system for carburetor-equipped internal combustion engines. The system utilizes an exhaust gas sensor to provide a feedback signal to a control unit. This signal is modified to align with the control characteristics of the closed loop. The modified feedback signal is then converted into digital pulses, with the pulse width varying according to the amplitude of the feedback signal. Additional air is supplied to the engine through an air bleed based on the magnitude of the analog feedback signal, allowing for coarse control of the air-fuel ratio. The system also responds to digital pulses for fine control, enabling a wide range of mixture ratios without the need for calibration.
