Abstract
The utility model discloses an air inlet pipe for a natural gas engine. The air inlet pipe comprises a pipe body, an air inlet cavity is formed in the pipe body, an air inlet communicated with the air inlet cavity and a plurality of uniformly-distributed air outlets are formed on both sides of the pipe body respectively, the air outlets are formed in parallel, the air inlet and the air outlets are in opposite directions, the air inlet is formed on the pipe body and is positioned in the middle of the length direction of the pipe body, the air outlets are connected with the pipe body through an air inlet branch pipe, the air inlet branch pipe is arc-shaped and is in smooth transition connection with the air outlets and the air inlet cavity. The air inlet is formed in the middle of the length direction of the pipe body, the air inlet branch pipe is circular-arc-shaped, and the air outlets are in smooth transition connection with the air inlet cavity, thereby realizing uniform air inlet and reducing the air inlet resistance. Moreover, the air inlet branch pipe is lengthened, air inlet interference among cylinders is avoided, and the air inlet uniformity of each cylinder is high, thereby improving the performance of the engine.
Description
Technical field
The utility model relates to natural gas engine technical field, relates in particular to a kind of natural gas engine suction tude.
Background technique
At present, natural gas engine is to use inflammable gas as power raw material, rock gas has price advantage, and environmental protection, therefore rock gas is very popular with users, what natural gas engine entered cylinder is inflammable gas and air, each cylinder shares a suction tude, suction tude only has a suction port, the gas entering is assigned to each intake manifold, intake manifold is connected with each cylinder by air outlet, distribution by intake manifold to suction tude gas, at present, the intake manifold of the suction tude that natural gas engine uses is shorter, suction port biasing, each cylinder intake uniformity differs larger, affect the performance of motor.
Summary of the invention
Technical problem to be solved in the utility model is: the natural gas engine suction tude that a kind of air inlet distributed uniform is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of natural gas engine suction tude, comprise body, in described body, be provided with air-inlet cavity, the both sides of described body are respectively equipped with suction port and several equally distributed air outlets of being communicated with described air-inlet cavity, described air outlet be arranged in parallel, described suction port and air outlet towards the opposite, described suction port is arranged on described body, and be positioned at the middle part of described body length direction, described air outlet connects described body by intake manifold, described intake manifold is arc, rounding off connects described air outlet and air-inlet cavity.
As a kind of preferred version, described air outlet has 4, is uniformly distributed along the length direction of described body.
As a kind of preferred version, described suction port is equipped with air outlet the flange being connected with motor.
Owing to having adopted technique scheme, by by the centre of inlet tube body length direction, and suction port is arranged on body, and intake manifold is circular arc, and air outlet is connected with air-inlet cavity rounding off, make air inlet even, intake resistance reduces, and the length of intake manifold is also longer compared with originally, avoids each cylinder air inlet to disturb, each cylinder intake uniformity is better, thereby can improve the performance of motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 be Fig. 1 along A-A to sectional view;
In figure: 1, body; 11, air-inlet cavity; 2, air outlet; 3, intake manifold; 4, suction port.
Embodiment
As shown in Fig. 1 and Fig. 2 are common, a kind of natural gas engine suction tude, comprise body 1, in described body 1, be provided with air-inlet cavity 11, the both sides of described body 1 are respectively equipped with suction port 4 and several equally distributed air outlets 2 of being communicated with described air-inlet cavity 11, described air outlet 2 be arranged in parallel, described air outlet 2 has 4, length direction along described body 1 is uniformly distributed, described suction port 4 and air outlet 2 towards the opposite, suction port 4 is equipped with air outlet 2 flange being connected with motor, described suction port 4 is arranged on described body 1, and be positioned at the middle part of described body 1 length direction, described air outlet 2 connects described body 1 by intake manifold 3, it is just comparatively even that suction port 4 is assigned to the gas flow of each intake manifold 3 like this, described intake manifold 3 is arc, rounding off connects described air outlet 2 and air-inlet cavity 11, both increased the length of intake manifold 3, avoid each cylinder intake to disturb, and make intake resistance less.
Claims (3)
1. natural gas engine suction tude, comprise body, in described body, be provided with air-inlet cavity, the both sides of described body are respectively equipped with suction port and several equally distributed air outlets of being communicated with described air-inlet cavity, it is characterized in that: described in each, air outlet be arranged in parallel, described suction port and air outlet towards the opposite, described suction port is arranged on described body, and be positioned at the middle part of described body length direction, described air outlet connects described body by intake manifold, described intake manifold is arc, and rounding off connects described air outlet and air-inlet cavity.
2. natural gas engine suction tude as claimed in claim 1, is characterized in that: described air outlet has 4, is uniformly distributed along the length direction of described body.
3. natural gas engine suction tude as claimed in claim 1, is characterized in that: described suction port is equipped with air outlet the flange being connected with motor.
