The invention discloses a fuel oil supply device and method for a multi-fuel-charge compression combustion engine, and the device comprises two groups of direct injection systems arranged on the engine, two groups of air duct port injection systems connected with an air inlet pipe of the engine, a sensor group arranged on the engine, and an electronic control unit. Wherein the electronic control unit is respectively connected with the sensor group, the two groups of direct injection systems and the gas port injection system, judges the operation condition of the engine according to acquired sensor signals, and correspondingly outputs instructions to control the conveying of three fuels so as to realize the control of tail gas emission. The engine can be ensured to be in the optimal working state all the time, fuel consumption is reduced, tail gas emission is reduced, the optimal heat efficiency and the lowest emission are kept under all the working conditions, nitrogen oxide emission can completely meet the n
