Title: Tetsuya Ishino: Innovator in Marine Engine Technology
Introduction
Tetsuya Ishino is a notable inventor based in Shizuoka, Japan. He has made significant contributions to marine engine technology, holding a total of 7 patents. His innovative designs focus on improving the efficiency and functionality of cooling and air induction systems in small watercraft.
Latest Patents
One of Ishino's latest patents is a cooling system for marine engines. This system is particularly suited for use in small watercraft and is designed to supply and evacuate coolant from the engine effectively. The engine features a body that defines at least one water jacket. The coolant supply passage routes coolant into thermal communication with a portion of the exhaust system before supplying it to the water jacket. When the engine is turned off, the coolant drains from the water jacket through a drain passage, which is connected to the coolant supply passage upstream from the exhaust system. This design allows the coolant to travel in reverse through the supply passage, ensuring efficient drainage from the cooling system. During normal operation, a restriction orifice within the drain passage allows only a small amount of coolant to be supplied to the engine water jacket without routing it into thermal communication with the exhaust system.
Another significant patent is the air induction system for small watercraft. This system is designed to guide air into the engine for combustion. The induction system includes an inlet assembly that features various constructions to enhance water preclusive effects, ensuring optimal performance in marine environments.
