Abstract
A gaseous fuel supply device includes processing circuitry configured to control a direct injection valve and a shut-off valve. The processing circuitry determines an energization time for the direct injection valve based on a pressure of gaseous fuel supplied from a supply passage to the direct injection valve. When a temperature of the direct injection valve becomes greater than a temperature determination value, the processing circuitry starts an opening-closing process that repeatedly switches the shut-off valve between a closed state and an open state. The opening-closing process is a process that brings the shut-off valve into the closed state when the pressure of the gaseous fuel supplied to the direct injection valve is greater than a pressure lower limit value and brings the shut-off valve into the open state when the pressure of the gaseous fuel becomes less than or equal to the pressure lower limit value.
