Yusuke Kawai

Introduction

Yusuke Kawai is a renowned inventor based in Hiroshima, Japan, holding an impressive 35 patents. His work primarily focuses on the advancements in internal combustion engine technology, showcasing his dedication to innovation and efficiency in automotive engineering.

Latest Patents

Among his latest inventions is a control apparatus for compression-ignition type engines. This apparatus features an ignition control section and an injection control section designed for optimal combustion. When partial compression ignition is employed, the ignition control section initiates combustion through a main ignition phase that occurs late in the compression stroke or early in the expansion stroke. The system also incorporates preceding ignition, where the spark is generated earlier than the main ignition. Furthermore, the injection control section strategically times fuel injection to ensure fuel presence in the cylinder prior to the preceding ignition, optimizing performance based on in-cylinder temperature.

Another significant patent developed by Kawai relates to an internal combustion engine equipped with a variable phase mechanism. This mechanism alters the rotational phases of intake and exhaust camshafts, achieving precise valve overlap. The design of the intake cam lobe ensures that the open period of the intake valve efficiently manages crank angles, contributing to enhanced overall engine performance.
