As shown in fig. 1 and 2, an engine 100 according to an embodiment of the first aspect of the present utility model includes a cylinder head 1 and a camshaft housing 2.
Specifically, the cylinder head 1 is formed with a plurality of passages 11. In the description of the present utility model, "plurality" means two or more. The camshaft box 2 is arranged on the cylinder cover 1, the camshaft box 2 and the cylinder cover 1 jointly define a containing cavity 21, an inlet 22 is formed in the containing cavity 21, a flow guiding structure 23 is arranged in the containing cavity 21, at least one flow guiding channel 211 is jointly defined by the flow guiding structure 23 and the inner wall of the containing cavity 21, the containing cavity 21 comprises at least one resonant cavity 212, the resonant cavities 212 are respectively communicated with the channels 11, and the resonant cavities 212 are communicated with the inlet 22 through the flow guiding channels 211. For example, in the example of fig. 1 and 2, the lower side of the camshaft housing 2 is connected to the upper side of the cylinder head 1 in the up-down direction. The inlet 22 penetrates through the inner wall of the accommodating cavity 21, four channels 11 are formed in the cylinder cover 1, the four channels 11 are sequentially arranged at intervals along the left-right direction, and the four channels 11 are communicated with the accommodating cavity 21. The flow path of the fluid within engine 100 (e.g., indicated by arrow B in fig. 1) is generally as follows: the fluid enters the diversion channel 211 along the inlet 22, flows through the diversion channel 211 and flows into the resonant cavity 212, and finally the fluid in the resonant cavity 212 flows into the channels 11.
So set up, the simple structure of water conservancy diversion structure 23 is favorable to the production of water conservancy diversion structure 23. Meanwhile, the flow guide structure 23 and the accommodating cavity 21 together define a flow guide channel 211, and the flow guide channel 211 has a guiding function on the fluid flowing into the accommodating cavity 21, so that the fluid flowing from the inlet 22 can smoothly flow into the resonant cavity 212 under the action of the flow guide channel 211, thereby being beneficial to the fluid in the resonant cavity 212 to flow into the plurality of channels 11 more uniformly. Moreover, the smoothness of the fluid flow is improved, and turbulence of the fluid at the inlet 22 is avoided, thereby facilitating the flow of the fluid in the engine 100. In addition, the fluid collides with the inner wall of the resonant cavity 212 during the flowing process, so that the flowing path of the fluid is changed, the fluid can uniformly flow into the plurality of channels 11, the uniformity of combustion of each cylinder (not shown) in the engine 100 is improved, and the shaking of the engine 100 is avoided. When engine 100 is used for a vehicle, vehicle shake is effectively avoided. In addition, the passage 11 is provided in the engine 100, and the heat generated during the operation of the engine 100 prevents the condensation water remaining in the passage 11 from freezing in extremely cold weather, thereby reducing the influence on the operation of the engine 100. It should be noted that, the inlet 22 may be disposed on the camshaft housing 2, the inlet 22 may also be disposed on the cylinder cover 1, and the position of the inlet 22 and the number and arrangement of the channels 11 may be specifically set according to the actual situation, so as to better satisfy the practical application.
According to the engine 100 of the embodiment of the utility model, the diversion channel 211 is provided, so that the diversion channel 211 has a guiding effect on the fluid flowing into the accommodating cavity 21, and the fluid flowing from the inlet 22 can smoothly flow into the resonant cavity 212 under the action of the diversion channel 211, thereby being beneficial to the fluid in the resonant cavity 212 to flow into the plurality of channels 11 more uniformly. In addition, the resonant cavity 212 helps to change the flow direction of the fluid, so that the fluid is easy to uniformly flow to the plurality of channels 11, thereby improving the combustion uniformity of each cylinder in the engine 100 and avoiding the engine 100 and the vehicle from shaking. In addition, the passage 11 is provided in the engine 100, which can effectively prevent the condensed water remaining in the passage 11 from freezing in severe cold weather, thereby preventing the passage 11 from being blocked and further facilitating the normal use of the engine 100.
Further, referring to fig. 1 and 2, one end of the guide channel 211 communicates with the inlet 22, and the other end of the guide channel 211 communicates with the resonant cavity 212 and is opposite to at least one sidewall of the resonant cavity 212. For example, in the example of fig. 1 and 2, the end of the flow-directing channel 211 remote from the inlet 22 communicates with the resonant cavity 212, and the end of the flow-directing channel 211 remote from the inlet 22 is opposite at least one side wall of the resonant cavity 212. Fluid flows from the inlet 22 into the diversion channel 211 and then along the diversion channel 211 into the resonant cavity 212, where the fluid collides with at least one side wall of the resonant cavity 212, resulting in a change of the flow path of the fluid, and finally the fluid with the changed path flows to the plurality of channels 11 respectively. Thereby, the fluid flowing from the inlet 22 is facilitated to flow into the diversion channel 211, and the fluid flowing through the diversion channel 211 is ensured to flow to the side wall (such as the side wall indicated by arrow C in fig. 1) of the resonant cavity 212, so that the possibility of collision of the fluid with at least one side wall of the resonant cavity 212 is improved, the fluid is facilitated to uniformly flow into the plurality of channels 11, the combustion uniformity of each cylinder in the engine 100 is further improved, and the shake of the engine 100 is further avoided.
According to some embodiments of the present utility model, referring to fig. 1 and 2, both the inlet 22 and the resonant cavity 212 are formed on the opposite side wall of the camshaft housing 2 from the plurality of channels 11. For example, in the embodiment of fig. 1 and 2, the inlet 22 extends through the upper sidewall of the camshaft housing 2 and the resonator 212 is disposed opposite the plurality of channels 11. Thereby, the fluid in the resonant cavity 212 can smoothly flow into the plurality of channels 11, thereby further improving the smoothness of the fluid flow. In addition, the inlet 22, the resonant cavity 212, and the plurality of channels 11 are reasonably arranged to facilitate the flow of fluid within the receiving cavity 21, thereby facilitating normal use of the engine 100.
Referring to fig. 1 and 2, the junction of the inlet 22 and the resonant cavity 212 is opposite the flow directing structure 23 to define a flow directing channel 211. By the arrangement, the space of the accommodating cavity 21 can be reasonably utilized to be favorable for forming the flow guide channel 211, so that fluid can be guided after entering the flow guide channel 211 along the inlet 22, and the smoothness of fluid flow is improved. In addition, the arrangement among the flow guiding structure 23, the inlet 22 and the resonant cavity 212 is compact, so that the engine 100 is compact in structure, and the installation and the use of the engine 100 are facilitated.
Optionally, referring to fig. 1 and 2, a side surface of the flow guiding structure 23 facing away from the plurality of channels 11 has at least one flow guiding surface 231, the flow guiding surface 231 being configured to guide at least a portion of the fluid flowing in from the inlet 22 to at least one side wall of the resonant cavity 212. For example, in the example of fig. 1 and 2, the upper surface of the flow guiding structure 23 has at least one flow guiding surface 231, and an end of the flow guiding surface 231 remote from the resonant cavity 212 is opposite to at least a portion of the inlet 22. Thereby, at least a portion of the fluid flowing in from the inlet 22 contacts the guide surface 231 and flows to the side wall of the resonant cavity 212 along the extending direction of the guide surface 231, so that the fluid can smoothly flow from the inlet 22 to at least one side wall of the resonant cavity 212, and the accuracy of the fluid flow direction is improved.
According to some embodiments of the present utility model, referring to fig. 2, the guide surface 231 is formed as a concave surface recessed toward the plurality of channels 11. For example, in the embodiment of fig. 2, the flow guiding surface 231 is a downwardly concave cambered surface. Thus, the fluid is facilitated to smoothly flow into the guide passage 211 along the inlet 22, and the fluid flowing out from the end of the guide passage 211 away from the inlet 22 can be accurately caused to flow to the side wall of the resonant cavity 212, thereby facilitating the flow of the fluid in the resonant cavity 212.
According to some embodiments of the utility model, referring to fig. 1 and 2, the resonant cavities 212 are plural, and the inlet 22 is located between the plural resonant cavities 212. The flow guiding structure 23 is opposite to the inlet 22, and a plurality of flow guiding surfaces 231 are formed on the flow guiding structure 23, and the fluid flowing from the inlet 22 is suitable for flowing to the plurality of resonant cavities 212 through the plurality of flow guiding surfaces 231 respectively. For example, in the example of fig. 1 and 2, two resonant cavities 212 are provided, with the inlet 22 being located between the two resonant cavities 212. The flow guiding structure 23 is formed with two flow guiding surfaces 231, and the inlet 22 is located at an upper position between the two flow guiding surfaces 231. The fluid flowing from the inlet 22 can flow through the two diversion surfaces 231 into the two resonant cavities 212 respectively, and the fluid with the flow direction changed by the two resonant cavities 212 flows into the corresponding multiple channels 11 more uniformly. By such arrangement, the fluid flowing in from the inlet 22 is easily guided into the two resonant cavities 212 along the two guide surfaces 231 in a dispersed manner, so that the amount of the fluid entering the single resonant cavity 212 is reduced, the distribution uniformity of the fluid in the plurality of channels 11 is further improved, the use of the engine 100 is more facilitated, and the use performance of the engine 100 is further improved. It should be noted that, the number and arrangement of the resonant cavities 212 and the diversion surfaces 231 may be specifically set according to the actual situation, so as to better satisfy the practical application.
Further, referring to fig. 1, the plurality of resonant cavities 212, the plurality of channels 11, and the plurality of guide surfaces 231 are symmetrically arranged about the central axis of the inlet 22. For example, in the example of fig. 1, the two resonant cavities 212, the four channels 11 and the two flow guiding surfaces 231 are symmetrically arranged about the central axis of the inlet 22, the two channels 11 located on the left side of the flow guiding structure 23 and the resonant cavities 212 located on the left side of the inlet 22 are opposite and communicate with each other, and the two channels 11 located on the right side of the flow guiding structure 23 and the resonant cavities 212 located on the right side of the inlet 22 are opposite and communicate with each other. By this arrangement, the uniformity of the fluid flowing into the accommodation chamber 21 along the inlet 22 and then dispersed into the two resonance chambers 212 is improved, so that the uniformity of the distribution of the fluid in the four passages 11 is improved, and the uniformity of the combustion of each cylinder in the engine 100 is further improved.
According to some embodiments of the utility model, referring to fig. 2, the flow directing structure 23 is part of the camshaft housing 2. For example, in fig. 2, the flow directing structure 23 is integral with the camshaft housing 2. By the arrangement, the connection stability of the flow guiding structure 23 and the camshaft box 2 is enhanced, and therefore the long-term use stability of the flow guiding structure 23 is improved.
Alternatively, the cylinder head 1 and the camshaft housing 2 are fixedly connected by bolts (not shown), and the upper surface of the cylinder head 1 is stopped against the lower surface of the camshaft housing 2. By the arrangement, the connection tightness of the cylinder cover 1 and the camshaft box 2 is enhanced, so that the tightness of the accommodating cavity 21 is improved, the fluid is prevented from flowing out of the accommodating cavity 21, and the utilization rate of the fluid is improved. In addition, the attachment and detachment of the cylinder head 1 to and from the camshaft housing 2 is facilitated, thereby facilitating the assembly and maintenance of the engine 100.
According to some embodiments of the utility model, referring to fig. 1, the cross-sectional area of the resonant cavity 212 gradually increases in a direction toward the plurality of channels 11. For example, in the example of fig. 1, the cross-sectional area of the resonant cavity 212 gradually increases from top to bottom, the cross-sectional shape of the resonant cavity 212 may be configured as a trapezoid, and the resonant cavity 212 located on the left side of the inlet 22 is disposed between the plurality of channels 11 located on the left side of the flow guiding structure 23. So set up, resonant cavity 212's simple structure, production and processing is convenient to improve engine 100's production efficiency. In addition, after the fluid enters the resonant cavity 212, uniformity of the fluid flowing into the plurality of passages 11 is improved, thereby further improving uniformity of combustion of each cylinder in the engine 100.
According to some embodiments of the utility model, the volume of the resonant cavity 212 is V 1 The volume of exhaust gas generated by engine 100 in a single work is V 2 ，V 1 、V 2 The method meets the following conditions: v is 8 to or less 1 /V 2 And is less than or equal to 12. When the volume V of the resonant cavity 212 1 Volume of exhaust gas V generated by a single work with engine 100 2 When the ratio of (2) is smaller than 8, the volume of the resonant cavity 212 is smaller, and the uniformity effect of the fluid in the resonant cavity 212 is poor, so that the combustion of a plurality of cylinders in the engine 100 is uneven, and the engine 100 is easy to shake. When the volume V of the resonant cavity 212 1 Volume of exhaust gas V generated by a single work with engine 100 2 When the ratio of (2) is greater than 12, the volume of the resonant cavity 212 is large, which is inconvenient for the spatial arrangement of the engine 100, and thus is inconvenient for the installation and use of the engine 100. Thus, by setting the volume V of the resonant cavity 212 1 Volume of exhaust gas V generated by a single work with engine 100 2 Meet V of 8-less 1 /V 2 And 12, the effect of the resonant cavity 212 is ensured, and the fluid is facilitated to uniformly flow into the plurality of channels 11, so that the uniformity of combustion of a plurality of cylinders in the engine 100 is improved, and the engine 100 is effectively prevented from shaking. Moreover, the spatial arrangement of engine 100 is facilitated, and the spatial utilization of engine 100 is improved. For example, volume V of resonant cavity 212 1 Volume of exhaust gas V generated by a single work with engine 100 2 Satisfy V 1 /V 2 When=10, the fluid distribution effect of the cavity 212 is better.
