Title: Innovative Contributions of Makoto Miwa in Fuel Technology

Introduction

Makoto Miwa, a prolific inventor based in Kariya, Japan, holds a remarkable 27 patents that reflect his dedication to advancing fuel technology and internal combustion engines. His innovative approach focuses on enhancing the performance and efficiency of fuel systems, contributing to cleaner and more efficient automotive technologies.

Latest Patents

Among his latest inventions, Miwa has developed a Diagnostic Apparatus for Fuel-Property Reforming System. This system operates in a reforming driving mode, where an Exhaust Gas Recirculation (EGR) valve facilitates the recirculation of exhaust gas into the intake pipe. The reforming-fuel injector then injects a reforming fuel into the exhaust gas, which is vaporized and sent to a fuel-reforming catalyst, converting it into a more combustible fuel. A computer monitors the air-fuel ratio to identify malfunctions in the reforming-fuel injector, implementing a fail-safe process to prevent erroneous fuel injection.

Another significant invention is the Controller for Internal Combustion Engine. This system intelligently controls valve timing to create a negative valve overlap period, optimizing fuel reforming through direct injection followed by port injection. This innovation allows for precise self-ignited combustion control, enhancing engine performance by adjusting fuel injection quantities based on real-time combustion conditions.
