Provided is a DME fuel supply method in which a target supply amount of DME is supplied into a fuel tank (3) of an engine (1) through a fuel supply line (111). In the DME fuel supply method, the fuel supply line (111) is opened (step S3); thereafter, a pressure difference which is obtained by subtracting the pressure in the fuel tank (3) from the pressure of the fuel supply line (111) is monitored (steps S4); when the pressure difference is below a predetermined set value, a purging electromagnetic valve (RV-2) for the fuel tank (3) is opened (step S5); when the pressure difference is above the predetermined set value, the purging electromagnetic valve (RV-2) is closed. |
