Latest Patents

Yoshikazu Ohshima holds a patent for a gas fuel supply system for vehicles. This system is designed to stop the supply of fuel when the fuel pressure, sensed by a pressure sensor upstream of a regulator, falls to a predetermined value or less. This mechanism helps to avoid abnormal combustion caused by improper adjustments of the air/fuel ratio. The system is capable of detecting even slight variations in fuel pressure by monitoring it during intervals after a fuel shut-off valve has been closed. Additionally, it can identify abnormal states in the fuel system by comparing the accumulated value of injected fuel with the estimated fuel consumption in the tank. The patent also includes a feature that controls the peak current value of the fuel injection valve to ensure smooth engine starts, especially in low-temperature conditions.
