Universal electronic injection motorcycle throttle valve body

Abstract

The invention discloses a universal electronic injection motorcycle throttle valve body. The valve body comprises an air inlet manifold and a throttle valve main body, an air inlet seat connecting pipe is arranged between the air inlet manifold and the throttle valve main body, an air inlet manifold positioning groove is formed in a port of the air inlet manifold, a throttle valve body protrusion is arranged at an end opening of the throttle valve main body, an air inlet seat connecting pipe groove is formed in the end face of one side of the air inlet seat connecting pipe, and a plurality of air inlet seat connecting pipe protrusions are arranged on the end face of the other side of the air inlet seat connecting pipe. The air inlet seat connecting pipe groove is matched with the throttle valve body protrusion, and the air inlet seat connecting pipe protrusions are matched with the air inlet manifold positioning groove. Due to the fact that clamping grooves are designed in the air inlet manifold and the throttle valve main body respectively, and a protruding limiting structure is arranged on the air inlet connecting pipe mechanism, the air inlet manifold and the throttle valve main body can be connected at various relative positions conveniently, and universality of the throttle valve main body is guaranteed.

Description

technical field [0001] The invention relates to a motorcycle part, more specifically, a general electric fuel injection motorcycle throttle valve body. Background technique [0002] In order to adapt to the implementation of the National IV emission standards for motorcycles, all the original fuel motorcycles on the market need to undergo EFI transformation. One of the most important tasks is to transform the original motorcycle carburetor into a special throttle valve body for EFI. The installation method of the throttle valve body and the intake manifold that is common in the market is: directly connect the throttle valve body and the intake manifold by means of flange surfaces, and the relative installation position of the throttle valve body and the intake manifold is fixed. of. This will cause a problem. When this engine is matched with different motorcycle models, due to the different internal structures of various models, it will cause the throttle valve body and bo...

AI Technical Summary

Problems solved by technology

This will cause a problem. When the engine is matched with different motorcycle models, due to the different internal structures of various models, the throttle valve body and body parts (such as frame side pipes, frame middle beams, and body plastics) will etc.) interference

Generally, for different models, it is necessary to re-select or design the throttle body, which will increase the development cost and prolong the development cycle
