Abstract
The utility model belongs to suction tude technical field, particularly relate to a kind of engine air inlet tube, comprise suction tude body, described suction tude body offers suction port, have a pressure stabilizing cavity be communicated with described suction port in described suction tude body, described pressure stabilizing cavity is integrated the cavity structure of communication type.The beneficial effects of the utility model: processing is simple, and cost is lower, and Pressure measurement difference reduces greatly, make each cylinder burning conformity improve, improve power character and the Economy of motor significantly.
Description
Technical field
The utility model belongs to suction tude technical field, particularly relates to a kind of engine air inlet tube.
Background technique
Existing suction tude is for having manifold-type structure, there is in suction tude a pressure stabilizing cavity, and in pressure stabilizing cavity, be separated into multiple cavity, respectively intake manifold is provided with in each cavity, the intake duct that each intake manifold and engine cylinder cover is communicated with, when utilizing this suction tude to carry mixed gas in each cylinder of motor, mixed gas enters pressure stabilizing cavity after suction tude suction port, then enters by the intake manifold in each chamber the intake duct that engine cylinder covers again.
The suction tude of this structure above-mentioned is first higher to the designing and making required precision of each manifold, and each manifold length needs consistent, and manifold passage is smooth and easy, virtually causes that processing is bothersome and processing cost is high;
Separately, by calculating each cylinder Pressure measurement difference of this structure at about 1.5%-3%, each cylinder air inflow differs greatly, and burning conformity is poor, thus directly affects power character and the Economy of motor.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of engine air inlet tube, intake manifold is there is with the engine air inlet tube solving existing use, the air inflow difference causing mixed gas to enter in each cylinder of motor is large, and burning conformity is poor, affects the technical problem of motor usability.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of engine air inlet tube, comprise suction tude body, described suction tude body offers suction port, have a pressure stabilizing cavity be communicated with described suction port in described suction tude body, described pressure stabilizing cavity is integrated the cavity structure of communication type.
As improving further, the air outlet of described pressure stabilizing cavity is the full unenclosed construction consistent with the outlet side structure of described pressure stabilizing cavity.
After have employed technique scheme, the beneficial effects of the utility model are:
Owing to having a pressure stabilizing cavity be communicated with suction port in suction tude body, pressure stabilizing cavity is integrated the cavity structure of communication type, processing is simple, cost is lower, and mixed gas directly enters by pressure stabilizing cavity the intake duct that engine cylinder covers after suction port, motor each cylinder Pressure measurement difference is about 0.55% as calculated, and Pressure measurement difference reduces greatly, each cylinder burning conformity is improved, improves power character and the Economy of motor significantly.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model embodiment;
Fig. 2 is the worm's eye view of Fig. 1;
Fig. 3 is the rear view of Fig. 1;
In figure, 1, suction tude body, 2, suction port, 3, pressure stabilizing cavity, 4, air outlet, 5, mounting hole.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 to Fig. 3 jointly shown in, a kind of engine air inlet tube, comprise suction tude body 1, suction tude body 1 offers suction port 2, there is in suction tude body 1 pressure stabilizing cavity 3 be communicated with suction port 2, as shown in Figure 2, pressure stabilizing cavity 3 is integrated the cavity structure of communication type, and the air outlet 4 of pressure stabilizing cavity 3 is the full unenclosed construction consistent with the outlet side structure of pressure stabilizing cavity 3.
During concrete use, first by corresponding with engine cylinder cover for the mounting hole of 12 on suction tude body 15 and be fixed together by fastening piece, suction tude pad is set between suction tude body 1 and engine cylinder cover simultaneously, realize sealing between the two, the intake duct that pressure stabilizing cavity 3 in suction tude body 1 covers with engine cylinder is respectively corresponding to be communicated with, then mixed gas enters pressure stabilizing cavity 3 by suction port 2, directly enter in the intake duct of engine cylinder cover from the air outlet 4 of pressure stabilizing cavity 3, pressure stabilizing cavity 3 is the integrative-structure of communication type, and air outlet 4 is the structure of adaptive full open type, the Pressure measurement difference entered like this in each cylinder is little, each in-cylinder combustion conformity improves, effectively improve power character and the Economy of motor, overall structure is simple, user cost is high.
The utility model utilizes the suction tude of new structure, mixed gas is made directly to enter by pressure stabilizing cavity the intake duct that engine cylinder covers after suction tude suction port, motor each cylinder Pressure measurement difference is about 0.55% as calculated, Pressure measurement difference reduces greatly, each cylinder burning conformity is improved, improves power character and the Economy of motor significantly.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
