Introduction

Hirofumi Shinohara is a notable inventor based in Aki-gun, Japan. He has made significant contributions to the field of engine technology, holding a total of three patents. His work primarily focuses on improving engine efficiency and performance.

Latest Patents

One of his latest patents is an intake device for an engine. This device includes an intercooler, an intake passage with a downstream-side intake passage, and an EGR passage that recirculates exhaust gas to the downstream-side intake passage. The design features an intake-air supply opening that has a smaller area than the downstream-side face of the intercooler core. Additionally, the downstream-side intake passage includes an extension passage portion that extends upwardly along the downstream side wall. The intake-air supply opening is designed to separate the intake air flowing from the inside wall face of the extension passage portion, forming main streams of intake air within the extension passage. EGR introduction ports are strategically arranged to supply EGR gas toward these flowing main streams.

Another significant patent involves an engine control device and method. This invention determines whether the amount of condensed water remaining in an intake passage exceeds a predetermined upper limit. If this condition is met during engine operation in an unsupercharged mode, the device performs a condensed water discharging operation of a supercharger, allowing the condensed water to be discharged to the engine's cylinder.
