Title: The Innovative Mind of Naoya Matsuo: Pioneering Spark-Ignition Engine Technologies

Introduction

Naoya Matsuo, an inventive engineer based in Higashihiroshima, Japan, has made significant contributions to the automotive industry, specifically in spark-ignition engine technologies. With five patents to his name, his innovative approaches have set new standards in engine performance and efficiency.

Latest Patents

Matsuo's most recent patents include groundbreaking techniques for controlling spark-ignition engines. One notable patent outlines a method for controlling the engine when preignition is detected. In scenarios where engine speed is below a predetermined value, the air-fuel ratio is enriched. However, if preignition persists, the effective compression ratio is reduced, and fuel injection occurs during the compression stroke. This inventive process effectively suppresses preignition while minimizing adverse effects on emission performance and engine power output.

Another notable patent from Matsuo involves an abnormal combustion detection method for spark-ignition engines. It utilizes a vibration sensor to monitor maximum vibration intensity. If this intensity exceeds a certain threshold with regards to engine conditions, adjustments are made to the spark timing of the engine. By detecting changes in vibration before and after this adjustment, Matsuo's method reliably distinguishes between preignition and traditional knocking.
