Abstract

The utility model provides an air filter for an automobile engine, which is formed by fastening an upper casing and a lower casing by bolts. The air filter has the improvement that an air inlet pipe and an air outlet pipe are respectively arranged under both sides of the lower casing. By adopting the structure, the occupied space of the air filter is reduced, and the air filter is easy to arrange in the narrow engine chamber, and is directly fixed on the engine, thereby avoiding transmitting the vibration to the automobile body, decreasing the noise of the integral automobile, and enhancing the comfort of the automobile interior. In order to increase the air filtering efficiency, the space surrounded by the lower casing can be separated into two chambers by the air filter, the upper parts of the two chambers are communicated with the space surrounded by the upper casing, the direct passage between the air inlet pipe and the air outlet pipe is disconnected, the air flow requires to enter one chamber, then enters the space of the upper casing, flows into the other chamber from the space of the upper casing, and finally flows out. The upper casing of the air filter can be made into a flattest structure, thereby increasing the air inlet cross section and the air inlet expansion ratio, and decreasing the air inlet noise.

Description

The empty filter of a kind of motor car engine

Technical field

The utility model relates to a kind of empty filter structure of motor.

Background technique

Along with developing of automobile industry, people are more and more higher to the requirement of quality, performance, oil consumption and the noise etc. of automobile.Motor is when performance improves, and the oil consumption of motor, noise also increase thereupon.For reducing the noise of engine intake, in empty filter design process, not only need to consider empty this body bulk of filter, and turnover tracheae length and position are constantly adjusted optimization.

She Ji empty filter assembly structure in the past: normally suction tude links to each other with lower shell body, steam outlet pipe links to each other with upper shell, it is big that this project organization occupies the space, because the engine compartment space is limited, difficult arrangement, empty filter assembly can only be connected with vehicle body by the decoupling zero mode, so just very easily transfers vibrations to vehicle body, increases the car load noise.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of motor car engine empty filter, changes into and out of the position of tracheae on empty filter housing, reduces it thus to the taking of space, and is easy to arrange.

The technical solution of the utility model is as follows:

The empty filter of a kind of motor car engine, it is made of by bolton upper and lower casing together.Its improvement is the both sides that suction tude and steam outlet pipe are arranged in lower shell body.This structure is occupied the space of sky filter and is reduced, and makes it be easy to arrange in narrow and small engine bin, is convenient to it directly is fixed on the motor, avoids transferring vibrations to vehicle body, reduces the car load noise, improves travelling comfort in the car.

In order to increase it to airfiltering effectiveness, this sky filter also can become the separated by spaces that lower shell body surrounded two chambers, two chamber tops all communicate with the space that upper shell surrounds, like this direct path between suction tude and the steam outlet pipe is disconnected, air-flow need be through a chamber, enter the upper shell space then, again by the upper shell spatial flow to another chamber, could flow out.And it is more flat that so empty filter upper casing also can be done, and to increase air inlet sectional area and air inlet divergence ratio, reduces inflow noise.

To render a service in order further improving to filter, preferably also between the space that chamber and upper shell surrounded of the close suction tude of lower shell body, filter core to be set.

The utility model provides a kind of lower casing entrance and exit type empty filter structure for the limited vehicle in engine compartment space, arrange simple, assembling easily, excellent noise reduction effect, required fresh air when the motor operation can be provided, empty filter assembly integral noise reduction can be improved again, the petrol engine high-performance can be reached, low noise.

Description of drawings

Fig. 1 is an external structure schematic representation of the present utility model;

Fig. 2 is a generalized section of the present utility model;

Embodiment

Referring to Fig. 1, Fig. 2, this sky filter comprises sky filter upper shell 1, empty filter lower shell body 2, suction tude 3, steam outlet pipe 4 and filter core 5.Empty filter upper shell 1 is to be in the same place by bolton with empty filter lower shell body 2.Suction tude 3 and steam outlet pipe 4 are arranged in sky filter lower shell body 2 both sides.The space that empty filter lower shell body 2 is surrounded is divided into two chambers by a plastic board, promptly near first chamber 6 of suction tude 3, all communicates with the chamber that empty filter upper shell 1 surrounds near second chamber, 7, the first chambers 6 of steam outlet pipe 4 and the top of second chamber 7.And above near first chamber 6 of suction tude 3, arrange filter core 5.

When air flows into first chamber 6 through suction tude 3, it filters by filter core 5 earlier, and the back flows into the space of empty filter upper casing 1, flows into second chamber 7 downwards, after flow out steam outlet pipe 4 backs, enters engine air throttle.

The empty filter of this structural type can directly be fixed on the motor, and needn't be fixed on the vehicle body because its space is occupied and reduced.

Claims

1. empty filter of motor car engine, it is made of by bolton upper and lower casing together; It is characterized in that be furnished with suction tude in a side of described lower shell body, opposite side is furnished with steam outlet pipe.

2. the empty filter of motor car engine according to claim 1, it is characterized in that, the space that described lower shell body surrounded is separated into two chambers, and the direct path between suction tude and the steam outlet pipe is disconnected, and two chamber tops all communicate with the space that upper shell surrounds.

3. the empty filter of motor car engine according to claim 2 is characterized in that, is provided with filter core between the space that chamber and upper shell surrounded of the close suction tude of described lower shell body.
