Title: Innovations of Hidekazu Fujie
Introduction
Hidekazu Fujie is a notable inventor based in Yamato, Japan. He has made significant contributions to the field of automotive technology, particularly in fuel injection and exhaust purification systems. With a total of 10 patents to his name, Fujie's work has had a considerable impact on improving engine efficiency and reducing emissions.
Latest Patents
Fujie's latest patents include a fuel injection control information generation device and an exhaust purification system. The fuel injection control device aims to suppress both NOx emissions and fuel consumption deterioration. It features a test point information storage unit that holds various test points defined by engine speed, fuel injection amount, and oxygen concentration. The control information generation unit then produces fuel injection control information that optimizes fuel injection timing for minimal emissions and fuel consumption.
The exhaust purification system consists of a diesel oxidation catalyst (DOC) and two diesel particulate filters (DPF) positioned along the exhaust path. This system collects particulate matter from exhaust gas and includes electrodes to detect capacitance in the upstream DPF. A particulate matter accumulation estimating unit assesses the amount of particulate matter in the downstream DPF, while a forced regeneration control unit injects fuel into the DOC to burn off accumulated particulate matter when necessary.
