Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, is intended to be illustrative, and not restrictive, and it is intended that all such modifications and equivalents be included within the scope of the present invention.
In the following detailed description, directional terms, such as "left", "right", "upper", "lower", "front", "rear", and the like, are used with reference to the orientation as illustrated in the drawings. Components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.
Referring to fig. 1-2, an engine intake plenum 100 according to a preferred embodiment of the present invention has a plenum body defining an intake passage of an engine in which an ice blocking member 1 is disposed. The ice block blocking component 1 is provided with an annular part 13, the outer wall of the annular part 13 is matched with the pressure pipe body, a grid component 14 is arranged in the inner wall of the annular part 13, the grid component 14 comprises a plurality of separating sheets, the end parts of the separating sheets are fixedly connected to the inner wall, and the separating sheets divide the circular section defined by the inner wall into a plurality of gaps which are arranged in a grid shape.
As will be readily understood, one end of the pressure increasing pipe body is an engine connection port 31 that is connectable to a throttle body of an engine, the other end of the pressure increasing pipe body is connected to the outside, and the ice blocking member 1 is disposed upstream of the engine connection port 31. When the air temperature drops to zero, the mixed gas may be liquefied in the pipe body and further frozen when flowing through the air inlet pressure increasing pipe, and the formed ice blocks may be sucked into the throttle valve body to cause engine failure. For this reason, the mesh member 14 in the ice-blocking member 1 divides the cross section defined by the inner wall into a plurality of voids having a small area to effectively block the larger (i.e., ice larger than the size of the voids) from being sucked into the throttle body by the engine. When the engine continuously works, the temperature of the inlet air rises, ice blocks are melted into water in the pipe body, and the water is carried into the engine cylinder by airflow and finally discharged into the atmosphere. Meanwhile, the design has small influence on the inner section of the air inlet passage, so that the influence on the air inlet resistance of the air inlet pressure increasing pipe is extremely small.
Referring to fig. 1-2, the engine intake plenum 100, according to some preferred embodiments of the present invention, comprises two sections of first and second plenum bodies 2 and 3. The ice blocking member 1 has an outer connecting portion 11 and an inner connecting portion 12 which are integrally formed, wherein the inner connecting portion 12 includes the ring portion 13. The ice blocking member 1 may be arranged such that the outer connection 11 is in a relatively upstream position in the inlet line with respect to the inner connection 12. The outer connecting portion 11 and the inner connecting portion 12 are both substantially annular, the former having a slightly larger diameter than the latter. The ice block blocking component 1 is sleeved and fixed to the first pressure increasing pipe body 2 through the outer connecting portion 11 of the ice block blocking component, one end of the first pressure increasing pipe body 2 is connected to the outside, the inner connecting portion 12 of the ice block blocking component is embedded and fixed to the second pressure increasing pipe body 3, and one end of the second pressure increasing pipe body 3 is connected to a throttle valve body of an engine. By this design, the ice-blocking member 1 effectively constitutes a pressure inlet joint connecting two sections of pressure inlet pipe body by the outer connecting portions 11 and the inner connecting portions 12 at both ends, and the entire engine intake pressure inlet 100 can be formed by assembling the two sections of pressure inlet pipe body via the pressure inlet joint.
Further preferably, as shown with reference to fig. 2, the mesh member 14 in which the annular portion 13 communicates may be located at an end of the entire ice blocking member 1 away from the external connection portion 11, that is, the annular portion 13 is located at an end of the ice blocking member 1 downstream of the intake passage. And outer connecting portion 11 and inner connecting portion 12 can adopt different connected modes to fix to two sections pressure boost pipe bodys respectively, for example, first pressure boost pipe body 2 of fixed can be established to the mode cover that outer connecting portion 11 can the joint, and inner connecting portion 12 can set up the external screw thread, arranges the internal thread in the tip of second pressure boost pipe body 3 through the cooperation and realizes fixed connection, perhaps, outer connecting portion 11 or inner connecting portion 12 also can be via interference fit or utilize other modes such as fastener with first pressure boost pipe body 2, second pressure boost pipe body 3 respectively fixed connection.
According to further alternative preferred embodiments of the present invention, ice blocking member 1 does not have a connection for connecting a pipe body, i.e. is not used as a pressure inlet joint, unlike the above-described embodiments. In these embodiments, the inner pipe wall of the whole segment of the pressure inlet pipe body is provided with a clamping installation part at a proper position, the outer wall of the annular part 13 of the ice block component 1 is provided with a clamping structure matched with the outer wall, and the ice block component 1 is fixed in the inner pipe wall through the matching of the clamping structure and the clamping installation part. For example, the clamping installation portion and the clamping structure may be an annular groove and an annular protrusion, respectively, and the annular protrusion is embedded in the annular groove so that the ice blocking member 1 is fixed in the inner pipe wall of the pressure pipe body.
Of the above two preferred embodiments of the present invention, including the ice blocking member 1 having the outer connection portion 11 and the inner connection portion 12, there is an advantage in that the ice blocking member 1 is relatively easy to remove, replace and maintain.
According to some preferred embodiments of the invention, the ice blocking member 1 is integrally injection molded. In other alternative embodiments, in the ice blocking member 1 having the outer connecting portion 11 and the inner connecting portion 12, the ring portion 13 in the inner connecting portion 12 and the mesh member 14 composed of a plurality of partition pieces in the inner wall are manufactured by injection molding, and the outer connecting portion 11 and the inner connecting portion 12 are formed by assembling and fixing two portions separated from each other.
According to some preferred embodiments of the present invention, the respective spacers of the grid member 14 are arranged such that, among the plurality of gaps arranged in a grid-like manner, the maximum length and the maximum width of the inscribed rectangle of each gap are within the preset size interval. Thereby, the sizes of the plurality of pores are made as even as possible, thereby achieving both reduction of the adverse effect of the ice-block blocking member 1 on the intake resistance of the supercharged intake duct and blocking of smaller-sized ice blocks.
According to some preferred embodiments of the present invention, the length and width of any inscribed rectangle of each gap are respectively smaller than a preset maximum length threshold and a maximum width threshold, wherein the maximum length threshold is not larger than 25 mm, and the maximum width threshold is not larger than 12 mm. In this case, only ice cubes having a cross section of less than 25 mm × 12 mm are possible to pass through without being blocked. This is primarily designed in view of the extreme size of the ice that the throttle body will not be affected by normal operation. In order to minimize the adverse effect on the intake resistance of the engine, the design of the grid member 14 may be such that it is possible to form ice cubes of the necessary larger size, but still with relatively large voids.
According to some preferred embodiments of the invention, at least one of the spacers passes through the center of the circular cross-section. Further preferably, referring to fig. 2, the plurality of spacers may be configured to include a Y-shaped spacer 141, a main spacer 142 and a sub-spacer 143, the main spacer 142 divides the circular cross section into two semicircular cross sections, the Y-shaped spacer 141 and the main spacer 142 intersect at the center of the circular cross section, and divide the first semicircular cross section into three sector-shaped gaps with 60 ° angles and the second semicircular cross section into two quarter circular cross sections, and the sub-spacer 143 is parallel to the main spacer 142 and divides the two quarter circular cross sections into four gaps.
According to some preferred embodiments of the present invention, in order to minimize the adverse effect of the provision of the ice-blocking member 1 on the intake resistance of the supercharged intake duct, while making the necessary strength of the partition pieces of the mesh member 14, and taking cost into consideration, the partition pieces may be made of an engineering plastic or alloy material. It is further preferred that the separator is made of 30% glass fibre reinforced PA66 type plastic, said separator having a thickness not less than 1 mm and not more than 2 mm.
