Latest Patents

Kuriyagawa holds a patent for a fuel supply control device and fuel supply system. This device is designed to perform power supply control of a shut-off valve, which includes a first valve body that is positioned in a fuel supply path from a gaseous fuel tank to a regulator. The first valve body is opened in advance during power supply, while a second valve body opens due to a decrease in differential pressure between upstream and downstream after the first valve body is opened. The control unit of the device sets a delay time from the initiation of power supply to the shut-off valve to the initiation of fuel injection, based on the first fuel pressure upstream and the second fuel pressure downstream of the regulator. Fuel injection is initiated after the delay time has passed following the power supply to the shut-off valve. Kuriyagawa's innovative approach enhances the efficiency and reliability of fuel supply systems.
