Description

TECHNICAL FIELD The present invention relates to an intake device for an engine, and more particularly to a layout of an air cleaner and a battery in an engine room.

(Prior Art) Conventionally, as a layout of an air cleaner in a vehicle,
For example, as disclosed in Japanese Examined Patent Publication No. Sho 61-28041, in a vehicle in which a transmission is connected to the end of the engine, an air cleaner is provided above the transmission, and the dead space above the transmission is effectively used to effectively surround the engine. It is known that the items are compactly summarized.

(Problems to be solved by the invention) By the way, an engine is horizontally mounted on a front portion of a vehicle body so that an output shaft thereof is oriented in an axial direction of the vehicle body, and a transmission is provided on a side of the engine (vehicle body width direction side). Placed
In the case of FF type vehicles, the dead space above the transmission is located in the approximate center of the engine room,
In addition to the air cleaner, a battery can be arranged in this dead space, and in this case, the area around the engine can be made more compact. In that case, there is a demand for the air cleaner to smoothly introduce air, and on the other hand, there is a demand for protecting the battery from the hot air flowing backward from the radiator to prevent early deterioration.

The present invention was made by paying attention to such points,
The purpose of this is to lay out the air cleaner and the battery properly above the transmission so that the functions of the air cleaner and the battery can be fully exerted while keeping the area around the engine compact.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the solution means of the present invention is premised on an engine horizontally mounted on the front part of the vehicle body and having a transmission arranged on the side thereof. Then, an air cleaner and a battery are arranged above the transmission, and the air cleaner is arranged on the front side of the battery.

(Operation) With the above-described configuration, in the present invention, the air cleaner and the battery are arranged above the transmission, so that the dead space above the transmission is effectively used and the area around the engine is compacted.

In that case, since the air cleaner is arranged on the front side of the battery, the air cleaner is close to the air intake on the front of the vehicle body, and the intake passage for introducing air into the air cleaner is simple, and the air cleaner has no air flow. It is introduced smoothly.

Moreover, this arrangement prevents the hot air flowing backward from the radiator from being blocked by the air cleaner and hitting the battery,
The battery is protected against heat and prevented from premature deterioration.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show a V-type engine equipped with an intake device according to an embodiment of the present invention and installed in an FF type vehicle. In these figures, 1 is a vehicle body, and
An engine room 2 is formed at the front of the engine room 2, and a bonnet panel 3 is provided on the engine room 2.

In the engine room 2, a V-type engine 6 is mounted horizontally so that its output shaft faces the width direction of the vehicle body 1. Reference numeral 7 is a cylinder head cover arranged on the left bank of the engine 6, 8 is a surge tank arranged on the right bank of the engine 6, and the surge tank 8 and each cylinder are connected by an intake passage. There is. A transmission 11 is connected to the left side of the engine 6. Further, a radiator 12 is arranged in front of the engine 6.

An air cleaner 17 and a battery 13 are arranged above the transmission 11. The air cleaner 17 is arranged on the front side of the battery 13.

The outlet of the air cleaner 17 is connected to the surge tank 8 of the engine 6 via an air hose 18. The inlet of the air cleaner 17 is a fresh air duct 19
, And the fresh air duct 19 extends to the upper right portion of the radiator 12 and opens. Therefore, the air sucked by the fresh air duct 19 is filtered by the air cleaner 17, and then supplied from the air hose 18 to the surge tank 8 and then to the engine 6. Further, 20 is a resonator which has a fixed volume and is arranged at the lower left of the air cleaner 17, and the resonator 20 is connected to the inlet of the air cleaner 17 via a small-diameter communicating portion to reduce intake noise. Demonstrate the function of muting.

The battery 13 is covered with a battery cover 14. 15 is a battery duct, one end of which is a radiator 12
Is opened in the lower left part of the battery, and the other end is connected to the battery cover 14, and the traveling wind from the front is introduced into the battery cover 14 to cool the battery 13.

Therefore, in the above-described embodiment, since the air cleaner 17 and the battery 13 are arranged above the transmission 11, the dead space above the transmission is effectively used, and the area around the engine is compacted.

In that case, since the air cleaner 17 is arranged on the front side of the battery 13, the air cleaner 17 becomes closer to the front part of the vehicle body, the fresh air duct 19 becomes simpler, and the air is smoothly introduced into the air cleaner 17.

Further, with this arrangement, the hot air flowing rearward from the radiator 12 is not blocked by the air cleaner 17 and hits the battery 13, so that the battery 13 is protected against heat and early deterioration is prevented.

Moreover, since the traveling wind is introduced into the battery cover 14 by the battery duct 15, the battery 13 can be cooled well, and the early deterioration of the battery 13 is further prevented.

(Effects of the Invention) As described above, according to the intake system for an engine of the present invention, the engine is mounted horizontally on the front part of the vehicle body, the transmission is arranged on the side of the engine, and the air cleaner is arranged on the upper part of the transmission. And the battery is installed,
Since the air cleaner is arranged on the front side of the battery, the intake passage of the air cleaner can be simplified and the heat of the battery can be protected, and the dead space above the transmission can be effectively used to compact the area around the engine.
