Title: Innovations by Yukihiro Natsuyama
Introduction
Yukihiro Natsuyama is a notable inventor based in Anjo, Japan. He has made significant contributions to the field of fuel injection technology, holding a total of five patents. His work focuses on enhancing the efficiency and functionality of internal combustion engines.
Latest Patents
One of his latest patents is a fuel injection pump for an internal combustion engine. This innovative pump includes a valve that opens and closes an overflow passage, connecting a high-pressure chamber to a low-pressure chamber. The low-pressure chamber reserves low-pressure fuel, while the high-pressure chamber pressurizes fuel sent from the low-pressure chamber and discharges it to fuel injectors. The design features a plunger with intake grooves that facilitate communication between the high-pressure and low-pressure chambers during the pump's intake action. Additionally, the body of the pump contains a feed passage that connects the high-pressure chamber to a control chamber. The pressure in the control chamber is adjusted by a piezoelectric actuator, which influences the valve's operation, allowing for precise control over the fuel injection period and ratio.
Another significant patent is for a fuel injection system that integrates a fuel injector with a fuel pressure control chamber. This system creates pressure that forces a needle valve to open and close the nozzle hole. It includes an accumulator to retain fuel discharged from the nozzle hole and connects to the fuel injection pump through a single piping system. The volume of the fuel pressure control chamber can be adjusted using a piezo-actuator, and a check valve ensures that fuel is efficiently directed into the control chamber and accumulator.
