Title: Tsuyoshi Kitahara: Innovator in Air-Fuel Ratio Detection Technology
Introduction
Tsuyoshi Kitahara is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of automotive technology, particularly in the area of air-fuel ratio detection. With a total of 8 patents to his name, Kitahara's work has been instrumental in enhancing the efficiency and precision of fuel mixtures in combustion engines.
Latest Patents
One of Kitahara's latest inventions is a device for detecting the air-fuel ratio of a mixture over a wide range. This innovative device detects the air-fuel ratio by causing an electric current to flow through an oxygen ion-conductive solid electrolyte. This process facilitates the migration of oxygen ions between atmospheric air and a gas receiving portion, where exhaust gases from the combustion of the fuel mixture are diffused via gas diffusion restricting means. The device also includes means for detecting the electric current.
Another notable patent is the air/fuel ratio detecting device and control system using the same. This invention allows for increased precision control of the air/fuel ratio by selectively using a pump electric current indicative voltage and a pump electric voltage as an air/fuel ratio indicative signal. The pump electric voltage is utilized at stoichiometry, while the pump electric current indicative voltage is employed for air/fuel ratios other than stoichiometry. Additionally, the pump electric current indicative voltage is offset in response to step changes in the pump electric voltage, generating an air/fuel ratio indicative signal that changes rapidly at stoichiometry.
