Description

Exhaust-gas purifier and silencer for internal combustion engine

The utility model relates to a kind of engine exhaust gas filtering noise reduction device.

The various automobiles of making are equipped with silencing apparatus in the exhaust ports of motor end at present, be not provided with any filtering discharging waste gas, the device of black smoke, therefore, in the big city that automobile is concentrated, because travelling of a large amount of automobiles produces various waste gas, black smoke, cause urban air pollution, influence the health of human body.

The purpose of this utility model is to provide a kind of noise that can reduce I. C. engine exhaust, can filter the engine exhaust gas filtering noise reduction device of engine exhaust gas, black smoke again.

The purpose of this utility model is to realize like this, the utility model mainly includes pipe, filter core, taper dividing plate, inductor and regulator plate continuous action device in cover plate, body, middle tube, the punching, it is characterized in that: cover plate is provided with an annular punching base plate at the upper end appropriate location, cover plate again in the upper end respectively the ecto-entad side be provided with in body, middle tube and the punching and manage, pipe is arranged with outlet pipe at the steam ouput end in the punching;

Body is provided with connecting tube at entry end, be filled with thermal-protective material between this body and middle tube, in middle tube and punching, be provided with the tubular filter core between pipe, make in two in the tube and middle tube and filter core between be formed with a passage that communicates, and be arranged in the tube front end at inboard wall of tube body and be provided with the taper dividing plate of an indent, the taper dividing plate is provided with guide plate, and is provided with a pore at taper dividing plate upper limb corresponding to air deflector, form an air chamber between this taper dividing plate and body, be provided with inductor in the air chamber;

Middle tube is positioned at punching pipe front end and is provided with regulator plate in tube wall, and the connecting rod of a regulator plate continuous action device is compressed on the regulator plate upper end, and this adjusting continuous action device can be connected with the solenoid valve of gas tank, and solenoid valve and inductor are connected with the microprocessing systems of operator cabin.

Advantage of the present utility model is: whole device can be controlled by microprocessing systems, regulates exhaust back pressure automatically, makes motor when walking rapidly acceleration or high-voltage load, keeps exhaust unimpeded, does not influence horsepower; Can not only can reduce noise pollution again by the filtering oil flue waste gas, overcome the insufficient and waste gas that causes of diesel vehicle diesel combustion, the deficiency of useless smoke pollution air.

Fig. 1 is the utility model generalized section.

Fig. 2 is the A-A cross-section cutaway view of Fig. 1.

Fig. 3 is that garden of the present utility model awl dividing plate and body concern schematic representation.

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figures 1 and 2, the utility model mainly includes: pipe 4, filter core 5 in cover plate 1, body 2, middle tube 3, the punching, taper dividing plate 6, inductor 7 and regulator plate continuous action device 8 etc.; Wherein, appropriate location is equipped with an annular punching base plate 9 on the cover plate 1, and cover plate 1 is respectively equipped with body 2 in the upper end, pipe 4 in middle tube 3 and the punching, and make body 2 sheathed in pipe 4 in the tube 3 then sheathed again punchings, the rear end of pipe 4 is provided with an outlet pipe 10 in the punching.

Body 2 is equiped with connecting tube 11 at front end, and 3 in body 2 and middle tube are filled with thermal-

protective material

12, and 4 of pipes are provided with tubular filter core 5 in middle tube 3 and punching, and 3 in tube and middle 3 are formed with a passage that communicates 13,23 with 5 of filter cores in making; And body 2 inwalls be arranged in the tube 3 front ends be provided with a taper dividing plate 6 that concaves, make 2 of taper dividing plate 6 and bodys be formed with an air chamber 14, be provided with the inductor 7 that is used for testing exhaust back pressure and temperature variation in the air chamber 14.

As shown in Figure 3, guide plate 15 is housed on taper dividing plate 6, and offers pore 16 corresponding to guide plate 15 places at taper dividing plate 6 upper limbs.

As shown in Figures 1 and 2, middle tube 3 is in tube wall, be positioned at punching pipe 4 front ends and be provided with regulator plate 17, and the connecting rod 18 of a regulator plate continuous action device 8 is compressed on regulator plate 17 upper ends, this regulator plate continuous action device 8 is connected with the gas tank solenoid valve, and respectively inductor 7 is connected with the microprocessing systems of operator cabin with solenoid valve.

As shown in Figure 1, black smoke that internal-combustion engine is discharged or waste gas are entered in the air chamber 14 that taper dividing plate 6 and body 2 form by connecting tube 11 ends, and suitable guide plate 15 is entered the passage 13 of 3 in middle tube by pore 16, then again around in

tube

3 and 5 formed passages 23 of filter core in punching base plate 9 enters, black smoke and waste gas are after passage 23 filters via filter core 5, enter the interior pipe 4 of punching of noise reduction, last, by managing 4 in the punching after outlet pipe 10 discharges.

When the back pressure that black smoke or waste gas produced of internal-combustion engine discharge is excessive, the inductor 7 that is positioned at air chamber 14 can measure the overvoltage signal, and this signal passed to microprocessing systems, then this system makes regulator plate continuous action device 8, the set regulator plate 17 of pipe 4 front ends in the punching is opened, make the overvoltage of part directly enter the interior pipe 4 of punching of noise reduction, and discharge by outlet pipe 10.

In addition,

body

2 and 3 in middle tube be filled with thermal-protective material 12, therefore,, can't make body 2 take place to burn and scald by black smoke or the hot waste gas that internal-combustion engine is discharged.
