Abstract
On the basis of a decrease in a high-pressure detection value and a low-pressure detection value during fuel control using a CNG injector, an electronic control unit automatically switches the combustion control to combustion control using a gasoline injector even when the amount of CNG remaining is insufficient. When the first shutoff valve is forcibly switched to an closed state by inputting a forcible shutoff command of a first shutoff valve to a terminal and the combustion control using the CNG injector is performed, a switching process to the combustion control using the gasoline injector is inhibited regardless of the decrease in the high-pressure detection value and the low-pressure detection value.
