Description

[Detailed description of the invention] This invention relates to a front engine front drive vehicle, and more specifically, an air cleaner and a resonator are provided in the space above the transmission, and the intake system is used for both non-supercharged engines and supercharged engines. This invention relates to a front-engine, front-drive vehicle that makes it possible to install a resonator without changing the layout.

For front engine front drive cars,
Regardless of whether the engine is a non-supercharged engine or a supercharged engine, it is extremely economical as long as there is no major change in the layout of the intake system piping in the engine room. Furthermore, even if a mechanism for alleviating intake noise in the case of a supercharged engine is added, it will be more economical if the layout does not change significantly.

Based on the above points of view, the purpose of the present invention is to enable the supply air piping to be basically the same regardless of whether a non-supercharged engine or a supercharged engine is mounted on the tower, and to To provide a front engine front drive vehicle which is extremely advantageous in terms of noise control.

Embodiments of the present invention will be described below with reference to the drawings. As shown in a side view in FIG. 1 and in a rear view in FIG. 2, a transmission 2 is provided at the rear of an engine 1 provided in an engine room. An air cleaner 4 is fixed on the transmission 2 by a bracket 3,
Furthermore, the bracket 3 is located below the air cleaner.
A resonator 5 is located and fixed on the housing of the transmission 2.

In a front-engine, front-drive vehicle, there is a relatively large space above the transmission 2, and the air cleaner 4 and resonator 5 are housed in the space and are arranged at approximately the same height as the engine 1. The air cleaner 4 and the resonator 5 are communicated by a connecting pipe 6, and although the resonator 5 is of a resonant type in this embodiment, it may also be of a hollow type.

The bracket 3 is shown in FIG. 3 as a longitudinal rear view, as shown in FIG. 4 as a side view in the direction of the arrow in FIG. 3, and as shown in FIG. The legs 3A, 3B are in surface contact with the flange 2A of the housing 2, and the top plate 3C is for fixing and supporting the air cleaner 4. The legs 3A, 3B have holes 8, 8 through which bolts 7 are inserted. The top plate portion 3C is provided with holes 10 at four predetermined locations through which stud bolts 9 installed at four predetermined locations on the bottom of the air cleaner 4 are inserted. The legs 3A and 3B are each provided with holes 13 that can fit in bolt holes 12 of projections 11 (only one of which is shown in FIG. 6) provided on the lower left and right sides of the front surface of the resonator 5. Legs 3
A hole 15 is provided in the upper part of B for passing a bolt for fixing a rectangular bracket 14 that connects the bracket 3 and the engine main body 1A.

On the other hand, the top plate 5A of the resonator 5 is provided with a connecting port 16 for connecting the connecting pipe 6, and positioning claws 18, 18 that engage with notches 17 (only one shown) provided in the side walls 3D, 3D of the bracket 3. There is.

Instead of the positioning means of the resonator 5 using the notch 17 and the claw 18, a hole 19 is provided in the side wall 3D of the bracket 3, and a hole 20 is provided on the side of the resonator 5, as partially shown in a perspective view in FIG. The bolt 22 and the nut 2 are
3 may also be used.

In the figure, reference numeral 24 is a set plate, 25 is a primary side opening of the air cleaner 4, 26 is a secondary side opening, 27 is a rubber washer, 28 is a spring washer, and 29 is a nut.

The front engine front drive vehicle of the present invention having the above-mentioned structure has an air cleaner 4 above the transmission 2 provided at the rear of the engine 1.
Since the resonator 5 is installed in a non-supercharged engine, the air flowing from the primary side of the air cleaner 4 to the secondary side is directly supplied to the intake manifold (not shown) provided on one side of the engine 1. In the case of a supercharged engine, exhaust from an exhaust manifold (not shown) provided on the other side of the engine 1 is supplied to a turbocharger (not shown) also provided on the side of the engine 1. The air flowing from the air cleaner 4 to the turbocharger is made high-pressure and is supplied to the intake manifold. At this time,
If a charge air cooler (not shown) is installed, the charge air cooler will be interposed in the same system.

In either case, the air cleaner and resonator installed on the transmission 2 at the rear of the engine 1 are of course connected to the intake manifold.
The air supply system piping required for connection with turbochargers, charge air coolers, etc. becomes extremely simple.

Furthermore, since the top of the transmission 2 is the center of gravity mount for front-engine, front-drive vehicles, it is extremely advantageous in terms of vibration levels. This is extremely effective in reducing intake noise.

FIG. 8 shows a side view of a modification in which an air cleaner 4 is attached to the bracket 3 and a resonator 5 is attached thereon.

9, 10, 11, and 12 respectively show examples in which the air cleaner 4 and the resonator 5 are arranged at the same level on the left and right sides, but in each case, the air cleaner 4 and the resonator 5 are It is fixed to the engine body and transmission and supported by a bracket 3 provided on the transmission.

As is clear from the above explanation, the front-engine, front-drive vehicle of the present invention has an air cleaner and a resonator installed on the transmission, which were not used in the past, so it can run either a non-supercharged engine or a supercharged engine. Even in this case, the intake system can have a reasonable piping layout, most parts can be used in common, and in particular, intake noise can be reduced.
