Title: Masaki Nishizawa: Innovator in Air/Fuel Ratio Control Systems

Introduction

Masaki Nishizawa is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of internal combustion engines, particularly in the development of air/fuel ratio control systems. With a total of 2 patents to his name, Nishizawa's work has had a meaningful impact on automotive technology.

Latest Patents

Nishizawa's latest patents focus on innovative air/fuel ratio control systems for internal combustion engines. The first patent describes a system that includes a first air/fuel ratio detector positioned upstream of a catalytic converter. This detector measures the air/fuel ratio from exhaust gas components. The system also features a second air/fuel ratio detector located in the exhaust system, which has a slower detection response speed. The control device adjusts the air/fuel ratio based on comparisons between the first detector's readings and a predetermined reference value. Additionally, it corrects the control based on the second detector's readings and shifts the reference value to a lean air/fuel ratio side during specific engine operation states.

The second patent similarly outlines an air/fuel ratio control system for internal combustion engines. It includes an air/fuel ratio detector positioned upstream of a catalytic converter and a control device that adjusts the air/fuel ratio based on comparisons with a reference value. This system also allows for shifting the reference value to a lean air/fuel ratio side during specific operational conditions.
