The invention provides an electromagnetic valve group mounting bracket of a dual-fuel engine, which comprises a long strip base plate and a side plate welded on the base plate, wherein a longitudinal section formed after the long strip base plate and the side plate are welded is in an L shape; the left end and the right end of the base plate are respectively provided with a mounting hole matched with an engine; and the positions of the side plate approaching both ends are respectively provided with a projection welding nut for assembling an electromagnetic valve group. When the electromagnetic valve group bracket is improved, both ends of the side plate are formed symmetrical L-shaped bends, the whole side plate is approximately shaped like the Chinese character ji, and the L-shaped bend is arranged outside the projection welding nut; both ends of the side plate are formed a structure similar to a reinforcing rib by the side plate structure in a shape like the Chinese character ji; and the model state and the strength of the bracket can be improved and the integral working reliability can be reinforced under the condition of not increasing the thickness of bracket materials.
