BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for engine peripheral parts.

[0002]

2. Description of the Related Art As a conventional support structure for engine peripheral parts, a structure shown on page B-30 of "New Car Manual (R10-1)" issued in June 1990 by Nissan Motor Co., Ltd., or FIG. There is something like that shown in

Reference numeral 1 denotes an engine, and a cylinder block 2
And a cylinder head 3 mounted on the upper side thereof, and an oil pan 4 mounted on the lower side of the cylinder block 2 for pooling lubricating oil. This engine 1
Are arranged in an upright state, and an intake manifold (engine peripheral parts) 5 composed of a plurality of pipe members is provided on a side surface portion on the rear side (A direction in the drawing) of the cylinder head 3. The distal end portions of these intake manifolds 5 are connected to an intake collector (engine peripheral parts) 6 to be integrated.

[0004] The lower end of the intake collector 6 has bolts 11a and 2b attached to the boss portions 2a and 2b of the cylinder block 2, respectively.
Are supported from below by the two stays 7a and 7b attached at the positions. Also, of the boss portions 2a and 2b,
Only the upper end 10 of the support bracket 9 for the drive shaft 8 is fastened to the upper boss 2a together with the lower end of the stay 7a by a bolt 11. Since the lower end of the support bracket 9 gets over the position of the oil pan 4, it is not fixed anywhere and is in a free state.
The reason that the support bracket 9 is in a cantilever state with only the upper end portion 10 in this manner is that the height position of the support bracket 9 itself is now set because the drive shaft 8 needs to be positioned at a constant height H. This is because they cannot be moved upward.

[0005]

However, in such a conventional technique, the distance between the bosses 2a, 2b of the cylinder block 2 and the intake collector 6 is long, and the length of each stay 7a, 7b is large. Because of this, the support strength of each of the stays 7a and 7b is reduced, and a plurality of stays 7a are required to support the intake collector 6 of the intake manifold 5 as in the conventional example. , 7b are required. Therefore, it is very disadvantageous in terms of weight and cost. As a countermeasure,
It is conceivable that a short stay is attached to the support bracket 9 and the intake collector 6 is supported by this stay. However, since the support bracket 9 itself is in a cantilever state as described above, sufficient support is provided even in such a case. Strength may not be obtained.

The present invention has been made by paying attention to such a conventional technique, and provides a support structure for engine peripheral parts which can reliably support engine peripheral parts without increasing the number of stays. Is what you do.

[0007]

According to the present invention, there is provided a support structure for a peripheral component of an engine in which an engine is disposed in a state of being inclined to one side in a front-rear direction and a support bracket for a drive shaft is provided on a side surface of a cylinder block on the inclined side. And upper and lower ends thereof are fixed to each other, and a connecting member attached to the support bracket supports an engine peripheral part.

[0008]

According to the support structure for engine peripheral parts according to the present invention, since the engine is arranged in an inclined state, the support bracket (drive shaft) for the engine is provided.
Relative height of the support bracket can be fixed to both the upper and lower ends of the support bracket to the cylinder block of the engine. Therefore, the mounting strength of the support bracket to the engine is greatly improved. Then, the connecting member is attached to the support bracket having the increased mounting strength, and the engine peripheral component is supported by the connecting member. Therefore, the support of the engine peripheral component becomes reliable and strong.

Further, since the connecting member is attached to the support bracket instead of the engine, the length of the connecting member is shorter than that of the related art. Therefore, the supporting strength of the connecting member is improved and the number of connecting members is one, which is very advantageous in terms of weight and cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIG. Here, the same reference numerals are used for portions common to the above-described conventional example, and the description is omitted.

The engine 20 according to this embodiment has an intake system component on the rear side and an exhaust system component on the front side, and the cylinder head 21 and the cylinder block 22 move rearward (direction A in the figure). The oil pan 25 attached to the lower part of the engine 20 has a lower surface in a horizontal state, and has an upper surface obliquely cut. As described above, the height H of the drive shaft 8 itself is the same as that of the related art because the engine 20 is tilted backward, but the relative position of the drive shaft 8 with respect to the engine 20 is increased. The support bracket 24 for supporting the shaft 8 has upper and lower ends 24a, 24b.
Bosses 26a, 26b of the cylinder block 22
Can be fixed by the bolt 11.

The distance between the support bracket 24 attached in this way and the intake collector (engine peripheral parts) 29 of the intake manifold (engine peripheral parts) 23 is close to each other. The upper and lower ends of short stays (connecting members) 27 corresponding to the distance are attached to the collector 29 with bolts 28, respectively, thereby supporting the intake collector 29 of the intake manifold 23 from below.

As described above, since the engine 20 is inclined rearward, the support bracket 24 is mounted not only on the upper side as in the conventional case but also on the upper and lower ends 24a and 24b. Can be firmly attached to the side surface of the cylinder block 22, and the mounting strength of the support bracket 24 is greatly improved. The stay 27 attached to the support bracket 24 allows the intake manifold 2
Since the third intake collector 29 is supported, the intake manifold 23 is reliably supported. Further, since the stay 27 is shorter than the conventional one, even one can reliably support the intake manifold 23, and there is no need to use a plurality of stays unlike the conventional one. Therefore, it is very advantageous in terms of weight and cost.

Next, another embodiment will be described with reference to FIGS. An engine 20 according to this embodiment has an exhaust system component disposed on the rear side and an intake system component disposed on the front side. Reference numeral 30 denotes a catalyst (engine peripheral component), which is not shown and protrudes from the cylinder head 21. It is connected to an exhaust manifold and absorbs harmful components of exhaust gas. The catalyst 30 is located behind the engine 20 and is supported by a stay 31 having one end attached to the rear end of the support bracket 24 as in the above-described embodiment.

The other constructions and functions and effects are the same as those of the previous embodiment, and a duplicate description will be omitted. In both of the above embodiments, the intake manifold 23, the intake collector 29, the catalyst 30, and the like are taken as examples of the engine peripheral parts. However, the present invention is not limited to these, and the exhaust manifold, the turbocharger, etc. The present invention can be widely applied to all components mounted around the engine 20.

[0016]

[Effect of the Invention] The support structure of the engine peripheral parts according to the present invention has the above-described contents. Since the engine is rearranged in an inclined state, the support bracket (drive shaft) relative to the engine is provided. As the height increases, both the upper and lower ends of the support bracket can be fixed to the engine cylinder block. Therefore, the mounting strength of the support bracket to the engine is greatly improved. Then, the connecting member is attached to the support bracket having the increased mounting strength, and the engine peripheral component is supported by the connecting member. Therefore, the support of the engine peripheral component becomes reliable and strong. Further, since the connecting member is attached to the support bracket instead of the engine, the length of the connecting member is shorter than before. Therefore, the supporting strength of the connecting member is improved and the number of connecting members is one, which is very advantageous in terms of weight and cost.
