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

Triangular rotor engine muffler

technical field

The utility model relates to an engine tail gas discharge device, in particular to a triangular rotor engine muffler.

Background technique

The engine in the car is generally a piston engine, and there are also rotary engines. Like the piston engine, the rotary engine also uses the pressure generated by the combustion of air and fuel mixture. In a piston engine, this pressure is maintained in the cylinder, which drives the piston. The connecting rod and crankshaft convert the back and forth motion of the pistons into the rotary motion that powers the car. In a rotary engine, the pressure generated by combustion is kept in a sealed chamber formed by the casing and the triangular rotor. The triangular rotor engine has a lower speed than the general engine, a small size and a high power, and the main shaft of the engine rotates once to perform work once and exhaust once.

At present, there are many kinds of matching mufflers for piston engines, but after the automobile exhaust enters the common muffler, it expands through the first chamber, the second chamber, and the third chamber in turn, and then is discharged from the tailpipe. Each chamber of this kind of muffler is easy to generate back pressure, the exhaust gas is not discharged smoothly, the combustion is not sufficient, it is easy to generate noise and vibration, and the fuel consumption of the car is also high.

Utility model content

Aiming at the shortcomings of the above similar technical problems, the purpose of this utility model is to provide a muffler for a triangular rotor engine.

The technical scheme of the utility model is: a triangular rotor engine muffler, including a muffler cylinder body, a partition I, a partition II, an air inlet pipe, an air guide pipe, and an air outlet pipe, and is characterized in that: the muffler cylinder passes through the partition I and the partition II Divided into the first chamber, the second chamber and the third chamber, the air inlet pipe extends into the first chamber through two partitions, and the air guide pipe passes through the two partitions to connect the first chamber and the third chamber chamber, and the air outlet pipe passes through two partitions to connect the third chamber with the outside world.

Air guide holes are opened on the inlet pipe where it enters the third chamber and the second chamber.

Air guide holes are opened on the partition I.

The utility model has the advantages that: by increasing the exhaust path of the engine into the muffler, the muffler can distribute and adjust the back pressure between the chambers by itself, so as to reduce the back pressure and achieve the purpose of reducing noise, vibration and fuel consumption. Increased engine power.

Description of drawings

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

FIG. 2 is a schematic structural view of the separator I in FIG. 1 .

Detailed ways

Now in conjunction with the accompanying drawings, the technical content of the utility model is further described.

As shown in Figures 1 and 2, the inside of the muffler cylinder 1 is divided into the first chamber 101, the second chamber 102 and the third chamber 103 by the partition I2 and the partition II3, and the intake pipe 4 passes through the two partitions Extending into the first chamber 101, the air guide tube 5 communicates with the first chamber 101 and the third chamber 103 through two partitions, and the air outlet pipe 6 passes through the two partitions to communicate the third chamber 103 with the outside world. Air guide holes are formed on the inlet pipe 4 where it enters the third chamber 103 and the second chamber 102 . Air guide holes are opened on the separator I2.

When working, most of the exhaust gas of the engine enters the first chamber 101 through the intake pipe 4 for expansion, then enters the third chamber 103 for expansion through the air guide pipe 5, and finally discharges to the outside through the outlet pipe 6; The exhaust gas directly enters the second chamber 102 through the air guide hole on the intake pipe 4 where it enters the second chamber 102 for expansion, then enters the third chamber 103 through the air guide hole on the partition I2 for expansion, and finally passes through the outlet The trachea 6 is discharged to the outside; at the same time, a small amount of exhaust gas directly enters the third chamber 103 through the air guide hole on the inlet pipe 4 where it enters the third chamber 103 for expansion, and then is discharged to the outside through the outlet pipe 6; through three The exhaust path, the noise reduction and shock reduction effect of the exhaust gas are very good, and the airflow is discharged smoothly.
