Description
Technical field
The invention belongs to technical field of engines, specifically, relate to a kind of engine induction manifold joint pipe.
Background technique
The intake manifold of motor car engine directly is connected with Carburetor, and air is sent in the Carburetor, and enters the acting of motor internal combustion after gasoline mixes, for car load provides power.The general intake manifold and the structure of Carburetor have single chamber intake manifold to join single-barrel carburetor, and the two-chamber intake manifold joins the twin barrel carburetor dual mode, and the deficiency that their exist is:
1, uses single chamber intake manifold, the generation of streaming is arranged in intake manifold, intake resistance is bigger, it is not very abundant that gas mixes, and causes power character and Economy undesirable, and there is great restriction at the angle of inclination when motor installed, if change the setting angle of motor, must change intake manifold simultaneously, not only expense costliness, and the change cycle is very long.
2, use two-chamber intake manifold and twin barrel carburetor, because twin barrel carburetor complex structure, manufacture cost is higher, and component are more, the assembling difficulty, twin barrel carburetor is damaged easily, feasible use is inconvenience very, and also there is great restriction at the angle of inclination when motor installed, if the setting angle of change motor, also must change intake manifold, still have expense costliness, long problem of change cycle.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of can adapt to the engine induction manifold joint pipe that needs are installed between single-barrel carburetor and the two-chamber intake manifold.
Technological scheme of the present invention is as follows: a kind of engine induction manifold joint pipe, be to constitute by the Carburetor mounting disc that has the Carburetor mounting hole, the intake manifold mounting disc that has the intake manifold mounting hole and suction tude body, be connected by the suction tude body between described Carburetor mounting disc and the intake manifold mounting disc, the top of this suction tude chamber body is single chamber, and single chamber connects to the exterior edge face of Carburetor mounting disc; The bottom of described suction tude chamber body is a two-chamber, and this two-chamber communicates with single chamber respectively, and connects to the bottom surface of intake manifold mounting disc.
Adopt above technological scheme, make motor car engine can use the two-chamber intake manifold to join the structure of single-barrel carburetor, be connected by the present invention between two-chamber intake manifold and the single-barrel carburetor, be that intake manifold mounting disc of the present invention is fixed by the attachment face in bolt and two-chamber intake manifold outlet port, the outlet in two chambeies of intake manifold is docked with two-chamber of the present invention respectively; The Carburetor mounting disc is fixed by the attachment face of bolt and single-barrel carburetor inlet, and single chamber of the present invention is docked with the import of Carburetor.Like this ensureing that gas mixes fully, in the good dynamic property, can adapting to the needs of the different setting angles of motor,, make it attachment face with Carburetor inlet and adapt and get final product as long as adjust the angle of Carburetor mounting disc.
In order further to reduce intake resistance, to be convenient to install, above-mentioned suction tude body is an arc, and is mutual vertical between the shaft axis of the shaft axis of Carburetor mounting disc and intake manifold mounting disc.
For ease of processing, reducing cost, between above-mentioned Carburetor mounting disc, suction tude body and the intake manifold mounting disc integrative-structure by casting.
Adopt motor of the present invention to detect the chamber by experiment, the performance parameter of motor is as follows:
