Fig. 1 is a perspective view of a mounting structure of an internal combustion engine according to the present invention, fig. 2 is a partially enlarged view of a region a of the mounting structure of the internal combustion engine according to fig. 1, and fig. 3 is a partially sectional view of the mounting structure of the internal combustion engine according to fig. 2 along a line B-B. Referring to fig. 1 to 3, in the present embodiment, the internal combustion engine 100 includes an intake manifold 110, a positive crankcase ventilation chamber as a chamber 120, and an air cleaner as an intake member 130, and further includes not shown ventilation chambers, throttle valves, turbines, and other members, and a plurality of passages connecting the members, wherein the positive crankcase ventilation chamber as the chamber 120 is disposed outside the intake manifold 110, and the air cleaner as the intake member 130 is disposed outside the intake manifold 110, that is, the intake manifold 110, the positive crankcase ventilation chamber as the chamber 120, and the air cleaner as the intake member 130 are disposed adjacent to each other as shown in fig. 1 to 3, but the present invention is not limited to the specific composition of the internal combustion engine 100, and may be adjusted according to requirements.
Specifically, in the mounting structure of the internal combustion engine 100 of the present embodiment, the positive crankcase ventilation chamber as the chamber 120 includes the chamber upper cover 122 and the chamber lower cover 124 fixed to each other, the flat surface 126 is formed on the upper surface of the positive crankcase ventilation chamber as the chamber 120, and the protrusion 128 is formed on the flat surface 126 and extends above the intake manifold 110.
Further, the flat surface 126 and the protruding portion 128 are formed on the upper face of the chamber upper cover 122, the chamber upper cover 122 and the chamber lower cover 124 constitute a positive crankcase ventilation chamber as the chamber 120 for introducing positive crankcase gas (PCV gas) through a passage, not shown, after being fixed to each other, and the positive crankcase ventilation chamber as the chamber 120 can be fixed to the outside of the intake manifold. In this way, the flat surface 126 and the protrusion 128 may be integrally formed on the chamber cover 122 during the process of manufacturing the chamber cover 122 without providing a separate fixing structure. However, the present invention is not limited to the specific structure of the positive crankcase ventilation chamber as the chamber 120, and it can be adjusted according to the requirement.
In the mounting structure of the internal combustion engine 100 according to the present embodiment, the phrase "the flat surface 126 is formed on the upper surface of the chamber upper cover 122" means that at least a part of the upper surface of the chamber upper cover 122 is flat, and the flat region referred to herein is the aforementioned flat surface 126. Preferably, the upper surface of the chamber lid 122 is substantially flat, that is, although the upper surface of the chamber lid 122 has a concave-convex structure, the whole chamber lid 122 is substantially flat, so as to obtain a wide range of flat surfaces 126. However, as long as at least a portion of the upper surface of the chamber cover 122 is flat, the protrusion 128 may be formed as the aforementioned flat surface 126, and the present invention is not limited to the range of the flat surface 126, and may be adjusted as required.
In addition, in the mounting structure of the internal combustion engine 100 of the present embodiment, the air cleaner as the intake member 130 has the fixing portion 132. An air cleaner as the intake member 130 is mounted above the positive crankcase ventilation chamber as the chamber 120 and the intake manifold 110 with a fixing portion 132 fixed to the protrusion 128. More specifically, the fixing portion 132 is a fixing structure such as a plate extending outward from a casing 134 of the air cleaner as the air inlet member 130, and has an opening 132a into which the protrusion 128 is inserted.
In this way, in the process of mounting the air cleaner as the intake member 130 above the positive crankcase ventilation chamber as the chamber 120 and the intake manifold 110, the air cleaner as the intake member 130 is moved toward the protruding portion 128 by the fixing portion 132, and the protruding portion 128 is inserted into the opening 132a of the fixing portion 132. The protrusion 128 is, for example, a bolt (stud) and can be fixed to the fixing portion 132 after being inserted into the opening 132a, and a washer 140 (shown in fig. 2 and 3) can be disposed between the bolt as the protrusion 128 and the opening 132a of the plate as the fixing portion 132 as required. However, as long as the air cleaner as the air inlet member 130 has a fixing structure for fixing the protrusion 128, the present invention is not limited to the specific structure of the fixing portion 132, and it can be adjusted as required.
As described above, in the mounting structure of the internal combustion engine 100 according to the present embodiment, since the upper surface of the chamber upper cover 122 of the positive crankcase ventilation chamber as the chamber 120 is substantially flat and has the flat surface 126, the operation of mounting the air cleaner as the intake member 130 above the positive crankcase ventilation chamber as the chamber 120 and the intake manifold 110 by using an additional fixing means can be omitted by forming the protrusion 128 on the flat surface 126.
Further, in the mounting structure of the internal combustion engine 100 of the present embodiment, the positive crankcase ventilation chamber as the chamber 120 and the air cleaner as the intake member 130 are provided outside the intake manifold 110 so as to be adjacent to each other, respectively, and further, a space exists between the positive crankcase ventilation chamber as the chamber 120 and the air cleaner as the intake member 130. As such, the protrusion 128 formed on the flat surface 126 of the chamber upper cover 122 extends toward the air cleaner as the air intake member 130, and is located in a space between the positive crankcase ventilation chamber as the chamber 120 and the air cleaner as the air intake member 130, that is, in a space above the positive crankcase ventilation chamber as the chamber 120. With the above configuration, the protrusion 128 is formed on the flat surface 126 of the chamber cover 122, and the air cleaner as the air intake member 130 can be fixed by effectively utilizing the shape of the positive crankcase ventilation chamber as the chamber 120 and the upper space.
In the mounting structure of the internal combustion engine 100 according to the present embodiment, since the upper surface of the chamber upper cover 122, which is the positive crankcase ventilation chamber of the chamber 120, has the flat surface 126 in a wide range, the protrusion 128 can be formed on the flat surface 126 of the chamber upper cover 122 with good rigidity, compared to the case where the protrusion 128 is formed on the side or corner of the chamber upper cover 122. The radiated sound generated during the operation of the internal combustion engine can be reduced along with the increase in rigidity of the entire structure of the positive crankcase ventilation chamber as the chamber 120.
In summary, in the mounting structure of the internal combustion engine of the present invention, the internal combustion engine includes an intake manifold, a chamber provided outside the intake manifold, and an intake member provided outside the intake manifold, the flat surface is formed on the chamber, the protrusion is formed on the flat surface and extends above the intake manifold, and the intake member is fixed to the protrusion and mounted above the chamber and the intake manifold. In particular, the flat surface and the protruding portion are formed on the upper surface of the chamber upper cover. It can be seen that the protruding portion is in the space above the chamber, and therefore the protruding portion can fix the intake member as a fixing means without increasing the occupied space, and the protruding portion is integrally formed on the upper surface of the chamber to present a flat region and have good rigidity. Therefore, the utility model discloses a mounting structure of internal-combustion engine can effectively utilize the shape and the top space of cavity to come fixed component to have good rigidity, and then produced radiated sound when reducing the internal-combustion engine function.
