Title: **Etsuo Kawabata: Innovator in Automotive Technology**

Introduction

Etsuo Kawabata is a prominent inventor based in Wakoh, Japan, known for his significant contributions to automotive technology. With two patents to his name, he has made strides in developing innovative systems that enhance vehicle performance while addressing environmental concerns.

Latest Patents

Kawabata's latest patents include a **Throttle Opener Device for Vehicle Engines** and an **Exhaust Gas Recirculation Control Device for Internal Combustion Engines**.

The throttle valve opener is designed to be actuated by suction pressure from the intake passage of a vehicle engine, which weakens due to atmospheric air during specific operating conditions. Importantly, it cuts off suction pressure when the vehicle speed or engine RPM exceed predetermined values, or when the engine's cooling water temperature rises above a predefined limit. This innovative system effectively controls the engine's deceleration to minimize exhaust pollutants while ensuring that drivability remains unaffected.

His second patent focuses on the method and apparatus for exhaust gas recirculation within internal combustion engines. This design enables the recirculation of exhaust gases through a dedicated passage that connects the engine's exhaust and intake passages. Utilizing a vacuum-response type recirculation control valve, the system operates based on vacuum levels detected near the throttle valve, contributing to improved engine efficiency and reduced emissions.
