Title: Kazuji Minagawa: Innovator in Fuel Supply Systems

Introduction

Kazuji Minagawa is a notable inventor based in Tokoname, Japan. He has made significant contributions to the field of fuel supply systems, holding a total of 14 patents. His innovative designs focus on improving fuel efficiency and reducing vapor generation in internal combustion engines.

Latest Patents

One of his latest patents is a fuel supply system with fuel evaporation prevention. This system ensures that when the differential pressure between fuel flowing into and out of a fuel control valve reaches a predetermined value, the valve member is seated to terminate communication between the fuel inlet and outlet passages. This design maintains different fuel pressure levels, which helps suppress fuel vapor generation during engine stoppage while providing appropriate fuel injection pressure during rapid deceleration. Another significant patent is the antidissipation apparatus for evaporated fuel vapor. This apparatus connects the intake manifold and fuel tank through a purge passage, where a canister adsorbs evaporated fuel vapor. A purge pump, driven by fuel flow, delivers the adsorbed vapor to the intake manifold, ensuring efficient fuel management even in lean-burn engine types.
