Title: Nobuyuk Kobayashi: Innovator in Internal Combustion Engine Technology

Introduction

Nobuyuk Kobayashi is a notable inventor based in Toyota, Japan. He has made significant contributions to the field of internal combustion engines, particularly through his innovative designs and patents. His work focuses on enhancing engine efficiency and performance.

Latest Patents

Kobayashi holds a patent for a control device of an internal combustion engine. This invention features a swirl control valve located in the intake port. When the engine operates under partial load, a lean air-fuel mixture is introduced into the engine cylinders, while the swirl control valve is closed to create a swirl motion in the combustion chamber. Conversely, when the throttle valve is fully open, a rich air-fuel mixture is fed into the cylinders, and the swirl control valve remains closed. Additionally, the ignition timing is retarded. When the throttle valve is slightly closed, the swirl control valve is kept open, allowing an approximately stoichiometric air-fuel mixture to enter the cylinders, with a slight advancement in ignition timing.
