Description

Intake manifold structure Technical Field The utility model relates to the technical field of automobile engine accessories, in particular to an intake manifold structure. Background An intake manifold refers to an intake conduit after a carburetor or throttle body and before an intake port in a cylinder head. Its function is to distribute the air and fuel mixture from carburetor or throttle valve to the inlet channel of each cylinder. The term "manifold" is used because the air flow path is "split" after the air enters the throttle valve and passes through the manifold buffer system, and the number of cylinders of the engine corresponds to the number of cylinders of the engine, for example, four cylinders of the four-cylinder engine and five cylinders of the five-cylinder engine, so that the air, the fuel mixture or the clean air is distributed into each cylinder as uniformly as possible. The water cooler is a radiator, can keep a state without sound in the heat absorption and radiation process, basically has no noise, can radiate very fast, can radiate heat while running, has strong adaptability to surrounding temperature and environment, and has better adaptability no matter cold or hot. When the existing air inlet manifold is installed, a plurality of bolts are manually installed in corresponding bolt holes one by using a tool by a worker and then are connected and assembled with corresponding equipment; in order to facilitate installation and cleaning and maintenance in the future, a space is reserved for future further modification, some air inlet manifolds are up and down, the upper and lower parts of the upper and lower air inlet manifolds are required to be assembled before being installed on corresponding equipment, and when the air inlet manifolds are assembled, a plurality of bolts are connected and installed in corresponding bolt holes on the upper and lower air inlet manifolds in a manual installation mode of staff so as to complete integral assembly.
