Problems solved by technology

The existing fuel pump assembly is fixed and placed in the fuel tank through a special bracket. Once the shape of the fuel tank changes, the structure of the bracket and the structure of the fuel pump assembly must be adjusted accordingly, which greatly improves the motorcycle. Design and manufacturing costs increase the time cycle of motorcycle fuel pump assembly design, which is neither scientific nor economical

Abstract

The motorcycle oil supply system includes one oil tank and one fuel oil pump assembly. The fuel oil pump assembly outside the oil tank includes one primary filter, one electric pump, one fine filter and one pressure regulating valve connected successively to form one oil path. The fuel oil pump assembly has use and fixation not limited by the oil tank and occupies no volume inside the oil tank, so that the motorcycle oil supply system can lower the design and manufacture cost of motorcycle, shorten the design period, increase the volume of the oil tank and raise the range ability of the motorcycle.

Description

technical field [0001] The invention relates to an oil supply system of a motorcycle. Background technique [0002] The fuel supply system of the existing motorcycle includes a fuel tank and a fuel pump assembly, the fuel pump assembly is placed inside the fuel tank, and the fuel pump assembly draws fuel from the fuel tank to the engine. However, the structure of the motorcycle is very compact, and the space left for the fuel tank is very limited. Placing the fuel pump assembly in the fuel tank further reduces the fuel storage capacity of the fuel tank, which directly affects the battery life of the motorcycle. In addition, in order to attract more consumers, the appearance of motorcycles is constantly being updated. As the fuel tank is an important part of the appearance of the motorcycle, the change of the shape of the motorcycle will inevitably directly lead to the change of the shape of the fuel tank. The existing fuel pump assembly is fixed and placed in the fuel tank...
