Description

Mounting structure of power device and dual-fuel motorcycle Technical Field The utility model relates to the technical field of dual-fuel motorcycles, in particular to a mounting structure of a power device and a dual-fuel motorcycle. Background In the related technology, the current fuel motorcycle has higher cost on fuel, and the fuel cost for long-term use is a little expense. In addition, when the fuel oil motorcycle burns gasoline or diesel oil, various harmful gases are generated, and the pollutants pollute the atmospheric environment, exacerbate the environmental problems of haze and the like and also endanger the health of human bodies. Natural gas is a nontoxic, odorless and colorless gas, does not contain cancerogenic substances such as benzene, lead, sulfur and the like, is low in price, and has been widely used as automobile fuel at present, and is stored in a gas cylinder mounted on an automobile. Because the structure of the motorcycle is compact, for the motorcycle adopting fuel oil and natural gas simultaneously, the gas cylinder is difficult to place, and the rigidity and the strength of the frame are difficult to balance after the gas cylinder is installed, so that the control level of the vehicle is reduced. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the utility model provides the mounting structure of the power device and the dual-fuel motorcycle, the mounting layout of the gas cylinder is optimized, and the structural strength and rigidity of the vehicle are improved. A mounting structure of a power plant according to an embodiment of a first aspect of the present utility model includes: Frame, engine and gas cylinder, the frame includes the roof beam, well frame and chassis, and the chassis is located the roof beam lower part, and well frame is connected in the one end of roof beam, and the bottom and the roof beam of well frame are connected respectively at the both ends of chassis to roof beam and chassis enclose into first installation cavity, and the engine is located first installation cavity, and well frame includes two side frames, and two side frames enclose into second installation cavity, and first installation cavity and second installation cavity are linked together, and first installation cavity and second installation cavity are worn to locate by the gas cylinder.
