Abstract

A triangle rotator engine silencer comprises a silencer barrel body, a separating plate I, a separating plate II, an air inlet pipe, an air guide pipe and an air outlet pipe. The interior of the silencer barrel body is divided into a first chamber, a second chamber and a third chamber through the separating plate I and the separating plate II, the air inlet pipe penetrates through the two separating plates and stretches into the first chamber, the air guide pipe penetrates through the two separating plates and is communicated with the first chamber and the third chamber, and the air outlet pipe penetrates through the two separating plates and communicates the third chamber and the outside. Air holes are formed in the part, entering the third chamber and the second chamber, of the air inlet pipe, and air holes are formed in the separating plate I. The triangle rotator engine silencer has the advantages that a path through which engine tail gas enters the silencer to be discharged is added, the silencer can distribute and adjust backpressure among all the chambers by itself, the backpressure is made to be reduced, the purposes of reducing noise, reducing vibration and reducing oil consumption are achieved, and the power of an engine is improved.

Description

The rotary polygonal piston engine silencing apparatus

Technical field

The utility model relates to a kind of motor exhaust discharger, specifically is a kind of rotary polygonal piston engine silencing apparatus.

Background technique

Motor in the automobile generally is reciprocating engine, and rotary engine is also arranged.The same with reciprocating engine, rotary engine also is the pressure that utilizes air, fuel mixture burning to produce.In reciprocating engine, this pressure is kept in the cylinder, orders about the piston motion.Connecting rod and bent axle are converted to moving back and forth of piston for automobile rotatablely moving of power are provided.In rotary engine, the pressure that burning produces is kept in the closed chamber of housing and triangular rotor formation.Rotary polygonal piston engine is lower than the rotating speed of general motor, the volume small-power is big, and an exhaust of main axis rotation one week acting of motor once.

At present, the supporting silencing apparatus of reciprocating engine has a variety of, but after vehicle exhaust enters common silencing apparatus, after expanding through first chamber, second chamber, the 3rd chamber successively, discharges from tail pipe again.Each chamber of this silencing apparatus easily produces back pressure, and tail gas is discharged and had some setbacks, and it is insufficient to burn, and is easy to generate noise and vibrations, and the oil consumption of automobile is also very high.

The model utility content

At the deficiency that above-mentioned similar technical problem exists, the purpose of this utility model provides a kind of rotary polygonal piston engine silencing apparatus.

The technical solution of the utility model is: the rotary polygonal piston engine silencing apparatus, comprise silencer cylinder, dividing plate I, dividing plate II, suction tude, air pipe, steam outlet pipe, it is characterized in that: be separated into first chamber, second chamber and the 3rd chamber by dividing plate I and dividing plate II in the silencer cylinder, suction tude is passed two dividing plates and is extend into first chamber, air pipe passes two dividing plates and is communicated with first chamber and the 3rd chamber, and steam outlet pipe passes two dividing plates the 3rd chamber is in communication with the outside.

The position that enters the 3rd chamber and second chamber on the described suction tude has gas port.

Have gas port on the described dividing plate I.

The utility model has the advantages that: enter the path that silencing apparatus is discharged by increasing motor exhaust, this silencing apparatus can distribute, regulate the back pressure between each chamber voluntarily, back pressure is reduced, reach the purpose that reduces noise, reduction vibrations, reduces oil consumption, improved engine power.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of Fig. 1 central diaphragm I.

Embodiment

Now by reference to the accompanying drawings, technology contents of the present utility model is described further.

As shown in Figure 1, 2, be separated into first chamber 101, second chamber 102 and the 3rd chamber 103 by dividing plate I 2 and dividing plate II 3 in the silencer cylinder 1, suction tude 4 is passed two dividing plates and is extend into first chamber 101, air pipe 5 passes two dividing plates and is communicated with first chamber 101 and the 3rd chamber 103, and steam outlet pipe 6 passes two dividing plates the 3rd chamber 103 is in communication with the outside.The position that enters the 3rd chamber 103 and second chamber 102 on the described suction tude 4 has gas port.Have gas port on the described dividing plate I 2.

During work, the tail gas of motor is most to be entered into first chamber 101 by suction tude 4 and expands, and enters into the 3rd chamber 103 by air pipe 5 then and expands, and is discharged to the external world by steam outlet pipe 6 at last; Simultaneously the gas port of some tail gas by the position that enters second chamber 102 on the suction tude 4 directly enters second chamber 102 and expands, enter into the 3rd chamber 103 by the gas port on the dividing plate I 2 then and expand, be discharged to the external world by steam outlet pipe 6 at last; Also have the gas port of a spot of tail gas by the position that enters the 3rd chamber 103 on the suction tude 4 directly to enter the 3rd chamber 103 simultaneously and expand, be discharged to the external world by steam outlet pipe 6 then; Through three emission paths, the noise reduction of tail gas, shock dropping effect are fine, and the air-flow discharging is smooth and easy.
