Apparatus for determining a gas fuel shortage and fuel supply control device

摘要

A gas fuel shortage determination device that determines a gas fuel shortage includes: a pressure gauge that measures the pressure of the gas fuel; and a fuel shortage determining part that determines that the gasoline is insufficient in a case where the pressure measured by the pressure measuring part has changed from a value higher than a first threshold value to a lower value than the first threshold value, and determines the gasoline fuel is not insufficient in a case where the pressure measured by the pressure measuring member has changed from a lower value than a second threshold value higher than the first threshold value to a value higher than the second threshold value, wherein the fuel shortage The determination part determines that the gas fuel is not insufficient when the pressure measured by the pressure measuring part has changed from a lower value than the first threshold to a value higher than the first threshold for the first time after the pressure measuring part has started measuring the pressure.
