Introduction

Toshio Shioya is a notable inventor based in Urawa, Japan. He has made significant contributions to the field of internal combustion engines, holding a total of six patents. His work focuses on enhancing fuel efficiency and emissions control in automotive technology.

Latest Patents

One of his latest patents is a fuel feeding system for an internal combustion engine. This innovative fuel injection system features a fuel distributor connected to a fuel supply tube. The main fuel nozzles are strategically fitted into openings in the lower surface of the fuel distributor and holes in the intake manifold near the main combustion chambers. A holding member supports the mid-portion of the fuel nozzles and connects to the fuel distributor. Additionally, a fuel branching member supplies fuel to the sub fuel injection nozzle, which is sealed from the atmosphere by a cap. An accommodating chamber is formed within a holding cylinder that fits around the leading end portion of the sub fuel injection nozzle. A fuel mixer within this chamber emulsifies the fuel, which is then injected into the unit sub intake passage through an emulsion tube. A regulator valve is also attached to the branched fuel passage to regulate the fuel pressure of both the main and sub injection nozzles.

Another significant patent is an exhaust gas recirculation system for an internal combustion engine. This system employs a recirculation control valve in a passageway connecting the engine exhaust passage to the intake passage downstream from the throttle valve. An air conduit with an air control valve provides atmospheric air to the intake passage. Vacuum responsive actuators operate the control valves, regulated by a valve responsive to differential pressure between vacuum intensity in the intake passage and modified atmospheric pressure. This innovative design aims to improve engine efficiency and reduce emissions.
