PURPOSE: A fuel blending device for a liquefied petroleum gas (LPG) engine is provided to be light in weight and miniaturized in size and to have excellent fuel-air mixing efficiency. CONSTITUTION: A fuel blending device for a liquefied petroleum gas (LPG) engine comprises a housing (10), an opening and closing cylinder (20), a cylinder movement control unit, and a cylinder return unit (30). The housing includes a fuel mixing chamber (11), a main fuel flow path (12), and a main air flow path (13); where the main fuel flow path and the main air flow path intersect in the housing. The opening and closing unit has a blocking projection and a blocking part which blocks the main air flow path when the blocking projection blocks the main air flow path, and moves to open the main fuel flow path and the main air fuel flow path. The cylinder movement control moves the opening and closing cylinder to open the main fuel flow path and the main air flow path. The cylinder return unit moves the opening and closing cylinder to block the main fuel flow path and the main air flow path.
