Title: Takahide Kuma: Innovator in Engine Control Systems
Introduction
Takahide Kuma is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of electronic control engines, holding 2 patents that showcase his innovative approach to engine management systems.
Latest Patents
One of his latest patents is a learning control system of air-fuel ratio in electronic control engines. This system computes the final fuel injection amount TAU based on a specific formula. Another important patent is an engine idling rotational speed control device. This device utilizes a stepping motor to control the opening area of an intake air flow rate control valve. It ensures that the engine rotational speed in a substantially full-close position of a throttle valve is maintained within a target rotational speed range, which is related to the engine coolant temperature. The system detects the intake air quantity and engine rotational speed to determine the ratio of these two factors. Notably, downward control to the intake air flow rate control valve is inhibited when the ratio of intake air quantity to engine rotational speed falls below a predetermined reference.
