Introduction

Hideaki Yokohata is a notable inventor based in Hatsukaichi, Japan. He has made significant contributions to the field of engine control technology, holding 2 patents that showcase his innovative approach to enhancing engine performance.

Latest Patents

One of Yokohata's latest patents is an engine control device. This device includes an injector with a needle that can be displaced between a closed position, where no fuel flows into a sac portion, and an open position, where fuel is allowed to flow. The control device features a fuel injection controller that manages the fuel injection period and an injector controller that regulates the needle's motion. Notably, the injector controller reduces the needle's moving speed before it reaches the closed position when the injection period concludes.

Another significant patent is a predictive analysis method and system for engine performance, along with a control program for its application. This system analyzes the flow of intake and exhaust gases in a four-cycle multi-cylinder engine using computational fluid dynamics (CFD). It allows for the selection of dimensions for analyzing gas flow during the intake, compression, expansion, and exhaust processes. The physical model simulates the gas flow from the intake to the exhaust system, enabling accurate predictions of engine performance while minimizing the time required for CFD operations.
