Abstract
The utility model discloses a guiding device of intake manifold inner chamber, intake manifold include the casing and rather than the lower casing of cooperation installation, still include the inner chamber between casing and the lower casing, the inner chamber includes the air inlet and is used for a plurality of air flues of giving vent to anger, just be equipped with the guiding mechanism that can make gaseous even reposition of redundant personnel in the inner chamber, reduce the vortex between air inlet and the air flue. The flow guide mechanism comprises a flow guide plate, and the flow guide plate is installed in a shape matched with the inner cavity. And a channel which can be used for guiding air flow is arranged on the guide plate. In order to realize the installation of the guide plate and the lower shell, the guide plate is connected with the lower shell through a clamping jaw. The utility model can evenly divide the gas in the inner cavity of the intake manifold, increase the length of the air premixing distance, reduce the vortex and smoothly divide the gas into each air passage; effectively guide the air current, reduce the vortex to alleviateed the impact force to the intake manifold inner chamber.
Description
Technical Field
The utility model relates to an auto parts device field especially relates to a guiding device of intake manifold inner chamber.
Background
The intake manifold is located between the throttle and the engine intake valve and is called the manifold because the air flow path is branched after the air enters the throttle and passes through the manifold buffer system, and the air flow path is branched corresponding to the number of the engine cylinders, for example, four paths exist in a four-cylinder engine and five paths exist in a five-cylinder engine, and the air is respectively introduced into each cylinder.
The air inlet manifold comprises a lower shell and an upper shell which is connected with the lower shell in a matching mode, an air flow channel is formed in the shell, and air flow enters from an air inlet and then enters each air passage respectively. The traditional air passage has large air flow space, short air premixing distance, easy generation of vortex, strong impact force and certain damage to the inner cavity of the air inlet manifold.
Disclosure of Invention
The purpose of the invention is as follows: the utility model provides a guiding device of intake manifold inner chamber, the device have solved traditional intake manifold inner chamber because the air current space produces the vortex greatly, to the great problem of inner chamber impact force.
The technical scheme is as follows: the utility model discloses a guiding device of intake manifold inner chamber, intake manifold includes the casing and rather than the lower casing of cooperation installation, still includes casing and the inner chamber between the casing down, the inner chamber includes the air inlet and is used for a plurality of air flues of giving vent to anger, just be equipped with between air inlet and the air flue and evenly shunt, increase the air and mix apart from the guiding mechanism of length, reduction vortex in the inner chamber.
In order to realize that the diversion mechanism shunts gas, the diversion mechanism comprises a diversion plate, and the diversion plate is installed in a matched manner with the inner cavity.
And a channel which can be used for guiding air flow is arranged on the guide plate. The uniform gas distribution is smoothly realized, and the eddy current is reduced.
In order to realize the installation of the guide plate and the lower shell, the guide plate is connected with the lower shell through a clamping jaw.
Has the advantages that: 1. the utility model can evenly distribute the gas in the inner cavity of the intake manifold, reduce the eddy and smoothly distribute the gas into each air passage; 2. effectively guide the air current, reduce the vortex to alleviateed the impact force to the intake manifold inner chamber.
Drawings
FIG. 1 is a schematic view of the structure and the direction of airflow of the present invention;
FIG. 2 is a schematic view of the structure of the baffle and the direction of the air flow;
fig. 3 is a schematic view of the connection structure between the middle deflector and the lower housing of the present invention.
Detailed Description
Referring to fig. 1 to 3, in the preferred embodiment of the present invention, the air inlet manifold includes an upper housing 1 and a lower housing 2 installed in cooperation with the upper housing 1, and further includes an inner chamber between the upper housing 1 and the lower housing 2, the inner chamber includes an air inlet 3 and a plurality of air passages 4 for giving vent to anger, and a flow guiding mechanism for evenly distributing air in the inner chamber and reducing vortex is disposed between the air inlet 3 and the air passages 4.
The flow guide mechanism comprises a flow guide plate 5, the flow guide plate 5 is installed in a matched manner with the inner cavity in shape, and is specifically connected with the lower shell 2 through a clamping jaw 6. And the guide plate 5 is provided with a channel which can be used for guiding the airflow.
The utility model discloses a theory of operation does: a guide plate 5 capable of enabling gas to be evenly distributed is arranged between the gas inlet 3 of the inner cavity of the gas inlet manifold and each gas passage 4, vortex is effectively reduced, and therefore impact force on the inner cavity is relieved when gas flows.
