A multi-fuel switching device, including a gas part, is provided. The gas part includes a switching valve. The switching valve includes a housing having an air inlet and an air outlet. An internal rotation of the housing is provided with a valve core located between the air inlet and the air outlet. The valve core is provided with a first airway and a second airway. Cross-sectional sizes of the first airway and the second airway are different. The first airway or the second airway is selected through rotating the valve core to connect the air inlet and the air outlet. The solution solves the issue that a fuel switching device in the prior art cannot adapt to three or more fuels, which causes an internal combustion engine to be unable to maintain the optimal working state.
