Description

The present invention relates to an engine cover mounting structure that covers a cylinder head cover attached to a cylinder head of an engine.

For example, in a vehicle where the engine as a drive source is housed in the engine room at the front of the vehicle body, a cylinder attached to the engine cylinder head is installed to suppress the radiation of engine noise to the outside and the propagation of radiant heat from the engine. A configuration is adopted in which the head cover is covered by the engine cover. In an engine, a cylinder head is attached to a cylinder block that is equipped with a cylinder and a piston that reciprocates within the cylinder, and this cylinder head has a cam mechanism that drives intake and exhaust valves, etc. Valve mechanism etc. are installed inside. A cylinder head cover is attached to this cylinder head, and this cylinder head cover is covered by an engine cover for the above-mentioned purpose.

By the way, regarding the engine cover, for example, Patent Document 1 discloses that the engine cover is divided into two parts, an intake side and an exhaust side, and the intake side engine cover, which is relatively low temperature, is made of synthetic resin, and the exhaust side, which is relatively high temperature. It has been proposed that the side engine cover be constructed from a laminated member in which an elastic material is sandwiched between a plurality of metal plates. According to such a configuration, it is possible to effectively insulate noise generated from the engine (particularly noise toward the exhaust side) and prevent deterioration of the sound absorbing material due to heat from the exhaust system.

Further, in Patent Document 2, the front and rear of the engine cover are each supported by cover mounting brackets, and one (rear) cover mounting bracket is provided with a stay that extends in the vehicle width direction near the auxiliary equipment. A configuration has been proposed in which a protector is attached to cover the rear of the vehicle for auxiliary equipment. According to this configuration, when an excessive force biased toward one side in the width direction is applied to the vehicle, the engine and parts disposed on the dash panel can be protected by the protector.

Conventionally, engine covers have been installed by, for example, forming a locking part on the head of a bolt that attaches the cylinder head cover to the cylinder head, and press-fitting an elastic member such as a grommet held on the inner surface of the engine cover into this locking part. It was done by doing.

However, the above mounting structure requires a special dedicated bolt (a special bolt with a locking portion formed in the head) as a bolt for attaching the cylinder head cover to the cylinder head, and therefore has the following problems.

That is, since they are special bolts, there is a problem in that not only does the cost increase, but also that management becomes complicated because it is necessary to assemble them during mass production (separation into normal bolts and special bolts). Additionally, when the engine cover is attached to a cylinder head cover that has relatively low rigidity, the engine cover resonates with the cylinder head cover, causing the problem that vibration and noise cannot be effectively suppressed depending on the engine cover. be.
Furthermore, as proposed in Patent Document 1, the cover is attached to the engine by fitting a long fitting pin extending from the head cover or cylinder head into a rubber bush attached to the inner surface of the engine cover. Therefore, if the rigidity of the fitting pin is low, there is a problem in that the engine cover resonates with the head cover and the cylinder head, and vibration and noise cannot be effectively suppressed by the engine cover.

Note that, as proposed in Patent Document 2, when a configuration in which the front and rear of the engine cover are respectively supported by cover mounting brackets is adopted, there is a problem that the number of parts increases.

The present invention has been made in view of the above problems, and its purpose is to suppress vibration and noise by the engine cover by attaching at least a portion of the engine cover to a highly rigid cylinder head without using special bolts. The object of the present invention is to provide an engine cover mounting structure that can enhance the effectiveness.

According to the above structure, the engine cover is supported by a simple operation of pushing the elastic member held on the inner surface of the extension part into the cylinder head cover side with the elastic member held on the inner surface of the extension part positioned on the locking pin attached to the support. It can be easily attached to the fixture with one touch. Further, since vibrations can be effectively absorbed by the elastic deformation of the elastic member, vibrations of the engine cover can be suppressed.

Furthermore, in the mounting structure of the engine cover (16), an end edge of the extension part (16B) of the engine cover (16) is bent at a substantially right angle to form a skirt part (16C). The mounting portion and a portion of the support (18) may be covered by the mounting portion.

According to the above configuration, the rigidity of the engine cover is increased by the skirt portion, so that vibrations of the engine cover are suppressed. Further, since the mounting portion and a portion of the support are covered by the skirt portion of the engine cover, the overall appearance of the engine is improved.

In addition, in this embodiment, the holders 16c and 16d are integrally provided on the inner surface of the engine cover 16, and a configuration is adopted in which these holders 16c and 16d do not open on the upper surface of the engine cover 16, so that the upper surface of the engine cover 16 is a flat surface, and the appearance of the engine cover 16 is improved. On the other hand, a configuration may be adopted in which the holders 16c and 16d are opened on the upper surface of the engine cover 16, and by adopting such a configuration, the grommet 17 and the grommet 17 when attaching the engine cover 16 as described above can be adopted. The advantage is that positioning with each of the locking pins 20, 21 is facilitated, and the work of attaching the engine cover is facilitated.

As described above, the engine cover 16 is attached to the cylinder head cover 15 at two places on the left and right on the intake side, and to the cylinder head 6 at two places on the left and right on the exhaust side. Since the engine cover 16 is attached to the highly rigid metal cylinder head 6 at two locations on the left and right sides of the exhaust side via the supports 18, the support rigidity of the engine cover 16 is increased. Therefore, the effect of suppressing vibration and noise by the engine cover 16 is enhanced.

In addition, since there is no need to use special dedicated bolts (bolts with a locking part formed on the head) used to attach the cylinder head 6 of the cylinder head cover 15 to attach the engine cover 16, there is no need to use them to attach the engine cover 16, which increases costs and reduces the need for mass production of bolts. There is no need to complicate management due to grouping. Furthermore, since a plurality of locations on the exhaust side of the engine cover 16 can be attached to the cylinder head 6 simply by adding the support 18, the number of parts does not increase significantly.

Furthermore, in the present embodiment, the engine cover 16 is formed with an extended portion 16B extending toward the exhaust system (exhaust pipe 11 and supercharger 12), and a mounting portion provided on the extended portion 16B is formed on the engine cover 16. Since the left and right parts of the exhaust side of the engine cover 16 are attached to the support 18 by the holder 16d, the grommet 17 held by the holder 16d, and the locking pin 20, the support rigidity of the extension part 16B of the engine cover 16 is reduced. As a result, the effect of suppressing vibration and noise and the effect of blocking radiant heat from the exhaust device by the extension portion 16B are enhanced.

Further, in this embodiment, the engine cover 16 is placed on the cylinder head cover 15 side with the grommet 17 held on the inner surface of the extension portion 16B positioned on the locking pin 20 attached to the support 18. It can be easily attached to the support 18 with one touch by simply pushing it in. In this case, since vibrations can be effectively absorbed by the elastic deformation of the grommet 17, vibrations of the engine cover 16 can be suppressed even more effectively.

Furthermore, since the skirt part 16C formed on the engine cover 16 covers the mounting part (holder 16d, grommet 17, and locking pin 20) and a part (upper part) of the support 18, the mounting part and the support 18 are covered. A part of the engine 1 is not exposed to the outside, and the appearance of the engine 1 is improved. Further, since the rigidity of the engine cover 16 is increased by the skirt portion 16C, vibrations of the engine cover 16 are suppressed.

Furthermore, in the present embodiment, since the left and right side plates 18A of the support 18 are arranged parallel to each other along the longitudinal direction of the vehicle, the running wind is guided to the cylinder head 6 by the rectifying action of the left and right side plates 18A. The cylinder head 6 is then cooled. Therefore, excessive temperature rise in the engine room of the vehicle that houses the engine 1 is effectively prevented. Since the support 18 is made of a metal plate, the rigidity of the support 18 is increased, so that the support rigidity of the engine cover 16 to the cylinder head 6 is increased.

In addition, in this embodiment, the grommet 17 held on the inner surface of the intake side of the engine cover 16 is attached to the locking pin 21 erected on the cylinder head cover 15 at two places on the left and right on the intake side of the engine cover 16. Since they are attached to the cylinder head cover 15 by press-fitting them, a total of four locations on the intake side and exhaust side of the engine cover 16 can be attached to the cylinder head 6 and cylinder head cover 15 with one touch by press-fitting the grommet 17 into the locking pins 20, 21. Easy to install. Furthermore, by making the spacing between the two locking pins 21 on the intake side and the spacing between the two locking pins 20 on the exhaust side different from each other, it is possible to prevent incorrect assembly of the engine cover 16 on the intake side and exhaust side. This can be prevented and the workability of assembling the engine cover 16 can be improved.

By the way, as shown in FIG. 8, as the support 18, one in which the left and right side plate portions 18A are erected in a straight line without bending can be used, and by using such a support 18, The exhaust side of the engine cover 16 can be arranged outside the exhaust side end of the cylinder head cover 15.

Although the present invention is applied to the engine cover mounting structure of a 4-stroke, 4-cylinder engine, the present invention is applicable to the engine cover mounting structure of any other 4-stroke, multi-cylinder engine. is similarly applicable.

In addition, the application of the present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims and the technical idea described in the specification and drawings.
