Title: Innovations in Diesel Engine Technologies by Masahiro Aketa

Introduction

Masahiro Aketa, a prominent inventor based in Sakai, Japan, has made significant contributions to the field of diesel engine technology. With an impressive portfolio of 24 patents, Aketa is renowned for his innovative solutions that aim to improve engine performance and reduce emissions.

Latest Patents

One of Aketa’s latest inventions is an exhaust treatment device for diesel engines. This advanced device incorporates an exhaust flow divider within the exhaust path, which enables the efficient management of exhaust gas. The design allows for the recirculation of EGR (Exhaust Gas Recirculation) gas, which contains particulate matter (PM), in a controlled manner. The first corona discharge passage at the exhaust flow divider generates electron attachment with PM, water vapor, and oxygen in the exhaust. This technology utilizes electrostatic forces to distribute the prepared EGR gas unevenly while maintaining a separate flow for discharged gas, leading to improved combustion efficiency. The second discharge passage further enhances the system by facilitating the dissociation of gas molecules, effectively reducing nitrogen oxides (NOx) in the discharged gas to harmless nitrogen.

Career Highlights

Masahiro Aketa is currently associated with Kubota Corporation, a leading player in the manufacturing and development of advanced agricultural and industrial machinery.
