Title: Hisatoshi Shibuya: Innovator in Fuel Control Technologies
Introduction
Hisatoshi Shibuya is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of fuel control technologies, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of fuel injection systems and high-pressure pumps.
Latest Patents
His latest patents include a "Control device for high-pressure pump and method for controlling the same." This invention involves a metering valve that supplies and blocks fuel from a pressurizing chamber by moving a valve body through the energization and de-energization of an electromagnetic unit. The energization control unit performs both valve closing and opening control to minimize operating sound during the opening and closing period. Additionally, a time control unit regulates the moving speed of the valve body to ensure that the energization period does not exceed the upper limit value.
Another significant patent is the "Control device for fuel injection system." This device is part of a fuel injection system that includes various components such as a low-pressure pump, a high-pressure pump, an accumulator, and a fuel injection valve. The high-pressure pump increases the fuel pressure and discharges high-pressure fuel, while the accumulator stores this fuel. The relief valve opens during high-pressure abnormalities, allowing the return pipe to redirect high-pressure fuel back to the low-pressure portion.
