Title: Kiyoshi Ohtaki: Innovator in Automotive Technology
Introduction
Kiyoshi Ohtaki is a notable inventor based in Fuchu, Japan. He has made significant contributions to automotive technology, holding a total of 6 patents. His work focuses on improving engine performance and efficiency through innovative systems.
Latest Patents
Ohtaki's latest patents include an automatic choke system for automotive engines. This system features a thermostatic spring connected to a choke valve, along with a heater designed to heat the thermostatic spring to open the choke valve. A control circuit regulates the current passing through the heater, allowing for a gradual opening of the choke valve when the engine starts and the cooling water temperature is below a predetermined level. Conversely, when the temperature exceeds this threshold, a rated current is supplied to quickly open the choke valve.
Another significant patent is an air-fuel ratio control system for internal combustion engines. This system incorporates an electromagnetic valve to adjust the air-fuel ratio of the mixture, an O₂ sensor to detect oxygen concentration in exhaust gases, and a feedback control circuit that generates pulses based on the oxygen concentration. The system also includes circuits for detecting engine deceleration and light load conditions, which produce a deciding signal. This allows for enriching the air-fuel mixture during deceleration when the throttle valve closes.
