Title: Innovations of Rio Shimizu

Introduction

Rio Shimizu is a notable inventor based in Mishima, Japan. He has made significant contributions to the field of internal combustion engines, holding a total of 5 patents. His work focuses on enhancing fuel supply systems, which are crucial for improving engine efficiency and performance.

Latest Patents

One of his latest patents is a fuel supply system and fuel supply method for internal combustion engines. This innovative system includes a heat exchanger that features a heat exchanging wall between a liquefied fuel passage and an engine coolant passage. The heated and vaporized fuel flows out from the liquefied fuel passage of the heat exchanger and is supplied to the internal combustion engine. The flow rate of liquefied fuel supplied to the heat exchanger is carefully set, while the flow rate of engine coolant is determined based on the temperature of the engine coolant. This design ensures that nucleate boiling or transition boiling of the liquefied fuel occurs near the boundary between these two boiling types in the liquefied fuel passage.

Another significant patent by Shimizu is a fuel feed system that causes liquid fuel to evaporate, thereby feeding gaseous fuel. This system includes an evaporator with a heater that heats the liquid fuel to vaporize it, along with an electric heater that adjusts the temperature of the heater. The heater is designed with a heat conduction surface that supplies heat to the liquid fuel. The difference between the temperature of the heat conduction surface and the boiling point of the fuel at the evaporator is utilized to change the heater's temperature and adjust the heat flux at the heat conduction surface.
