Title: Seiji Kunihiro: Innovator in Fuel Technology
Introduction
Seiji Kunihiro is a notable inventor based in Kariya, Japan. He has made significant contributions to the field of fuel technology, holding a total of 3 patents. His work primarily focuses on enhancing the efficiency and safety of fuel systems in automotive vehicles.
Latest Patents
One of Kunihiro's latest patents is a fuel pump that features a cylinder forming a compression chamber to pressurize fuel. This innovative design includes a plunger that compresses the fuel, a cam that pushes the plunger, and a driven gear that engages a driving gear to transmit rotational driving force. The cam's profile is configured such that the peak arrival range is half or less of the compression range. The cam speed is derived by differentiating the lift amount of the plunger by the rotation angle of the cam. This design ensures efficient fuel compression and delivery.
Another significant patent is an evaporated fuel leakage detector designed for automotive vehicles. This detector connects to the fuel tank through a canister that absorbs evaporated fuel. When the engine is not in operation, air in the fuel tank is drawn by a pump within the detector. If the pressure in the fuel tank drops to a predetermined level, it indicates that the evaporated fuel leakage is within an acceptable range. The detector's design includes a slanted orifice passage that reduces pressure loss, ensuring compactness while effectively detecting evaporated fuel leakage.
