Title: Innovations by Yasuhiko Hosoya in Engine Exhaust Gas Purification
Introduction
Yasuhiko Hosoya, an accomplished inventor based in Himeji, Japan, has made significant contributions to the field of engine technology, particularly in the purification of exhaust gases. With a remarkable portfolio of 19 patents, Hosoya has been instrumental in developing innovative systems that enhance the efficiency and effectiveness of internal combustion engines.
Latest Patents
One of Hosoya's latest patents is an "Apparatus for purifying engine exhaust gas." This innovative system includes an air introducing means that features an air pump for directing air into the exhaust pipe, along with a heating device designed to warm the introduced air. The heating device is integrated with a control unit that ceases heating once the engine's cooling water temperature surpasses a predetermined threshold. Additionally, the invention provides an idle rotation regulator that maintains the engine's rotational speed above idle level. A control unit is also implemented to activate the idle rotation regulator when the engine is idling, efficiently generating additional power through the dynamo to offset the energy consumed by the heating device.
Another significant patent encompasses a "Controlling apparatus for introducing air into an exhaust pipe of an internal combustion engine." This mechanism is designed to introduce air from the intake to the exhaust side, thereby enhancing exhaust gas purification efficiency and preventing a drop in catalyst efficacy under low starting temperatures. The invention includes a control valve situated in an air introducing pipe, which remains closed during the starting phase and for a brief period thereafter.
