Abstract
The utility model discloses an engine degassing pipe connects, remove trachea, cylinder cap including EGR and connect and house steward, EGR remove the trachea with the cylinder cap removes the trachea and connects respectively two inlet ends that Y type connects, the end of giving vent to anger that Y type connects is connected the house steward. The utility model provides an engine degassing pipe connects, two way degasings converge and adopt Y type articulate, and the engine degassing is more smooth and easy.
Description
Technical Field
The utility model relates to an engine cooling lubricating system technical field especially relates to an engine degassing pipe connects.
Background
Degassing is an important part of a waterway cooling system, because if gas is not removed in the cooling system, not only the cooling performance of the whole system can not be exerted, but also if steam is formed at a key component where bubbles are gathered, the key component can be damaged because the temperature of the steam is far higher than that of water. If the efficiency of the degassing system is not high, the cooling system needs to be operated repeatedly for multiple times of filling, and the working efficiency is low. According to the traditional engine air removal pipe, two paths of air removal and convergence are mostly connected in a T shape, as shown in figure 2, an EGR air removal pipe 1 and a cylinder cover air removal pipe 2 are connected through a T-shaped joint 5, and the traditional engine air removal pipe has the advantages that the pipeline is horizontal, flat, vertical and attractive. But causes a problem of poor degassing due to a large flow resistance.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides an engine degassing pipe connects, two way degasses converge and adopt Y type articulate, and the engine degassing is more smooth and easy.
The utility model discloses take following technical scheme to realize above-mentioned purpose:
the utility model provides an engine degassing pipe connects, removes trachea, cylinder cap including EGR and removes trachea, Y type joint and house steward, EGR remove the trachea with the cylinder cap removes the trachea and connects respectively two inlet ends that Y type connects, the end of giving vent to anger that Y type connects is connected house steward.
Preferably, the drift diameters of the main pipe are larger than the drift diameters of the EGR degassing pipe and the cylinder cover degassing pipe.
Preferably, the included angle of the two air inlet ends of the Y-shaped joint is designed to be 15-45 degrees.
The utility model has the advantages that:
the utility model discloses an engine degassing pipe connects, EGR removes trachea and cylinder cap and removes the trachea two way degasses and converge and adopt Y type articulate to join the house steward through Y type joint, can reduce the pipeline flow resistance, the engine degasification is more smooth and easy.
Drawings
FIG. 1 is a schematic structural diagram of an engine degassing pipe joint according to an embodiment of the present invention;
fig. 2 is a schematic structural diagram of an engine scavenging pipe joint provided in the background art.
In the attached drawing, 1-EGR degassing pipe, 2-cylinder cover degassing pipe, 3-Y type joint, 4-header pipe and 5-T type joint.
Detailed Description
The present invention will be described in detail with reference to fig. 1 and the following detailed description.
Referring to fig. 1, the present embodiment provides an engine degassing pipe joint, which includes an EGR degassing pipe 1, a cylinder head degassing pipe 2, a Y-joint 3, and a manifold 4. The EGR degassing pipe 1 and the cylinder cover degassing pipe 2 are respectively connected with two air inlet ends of the Y-shaped joint 3, and an air outlet end of the Y-shaped joint 3 is connected with the header pipe 4.
The utility model discloses an engine degassing pipe connects when using, EGR removes trachea 1 and cylinder cap and removes 2 two tunnel degasses of trachea and converge and adopt Y type to connect 3 and connect to connect 3 collection house steward 4 through Y type, can reduce the pipeline flow resistance, the engine degassing is more smooth and easy.
In the embodiment, the drift diameters of the header pipe 4 are larger than those of the EGR degassing pipe 1 and the cylinder cover degassing pipe 2, so that the flow resistance of a pipeline is reduced to a certain extent, and the degassing efficiency is improved.
The included angle of the two air inlet ends of the Y-shaped joint 3 is designed to be 15-45 degrees. In the present embodiment, the angle between the two air inlet ends of the Y-joint 3 is designed to be 45 °.
CAE analysis is performed on the flow of EGR (exhaust gas recirculation) degassing pipes and cylinder cover degassing pipes of two schemes (namely a T-shaped joint 5 in the background technology and a Y-shaped joint 3 in the scheme), and the results are shown in a table 1:
TABLE 1
| Flow rate | T-shaped joint | Y-shaped joint |
| EGR degassing pipe (L/min) | 1.95 | 2.50 |
| Cylinder cover degassing pipe (L/min) | 1.39 | 2.80 |
According to CAE analysis, the flow of the EGR degassing pipe can be increased by 0.55L/min by using the Y-shaped joint 3 instead, and is increased by 28 percent compared with the T-shaped joint 5 in the original scheme; the flow of the cylinder cover gas-removing pipe can be increased by 1.41L/min, which is increased by 101% compared with the T-shaped joint 5 in the original scheme. The main reason for flow promotion is that except that the position flow area that the trachea converges increases, adopt the Y shape to converge for the flow resistance reduces.
The degassing results for both solutions (i.e. the T-joint 5 in the background art and the Y-joint 3 in the present solution) are shown in table 2:
TABLE 2
Experiments prove that the engine degassing improvement effect is obvious after the Y-shaped joint 3 is used, and the degassing efficiency is high.
Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the scope of the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
