Description

Engine exhaust swirl exhaust pipe

technical field

The invention relates to the technical field of automobiles, and relates to an engine tail gas swirl exhaust pipe.

Background technique

With the development of science and technology, people's research on automobiles has also progressed from the shallower to the deeper, from the outside to the inside, and the research on the automobile emission control system has shifted from inside to outside. There are many kinds of modification of automobile exhaust pipes, such as increasing the diameter of the exhaust tail pipe, and changing the exhaust tail pipe to be thin and long, but these modifications have certain limitations, that is, the exhaust gas passes through the exhaust tail pipe The tube vents directly into the air. The exhaust gas of the automobile will be disturbed by the external air during the exhaust process, thereby forming a back pressure at the exhaust pipe port, slowing down the emission speed of the exhaust gas generated by the automobile engine, thereby hindering the engine from inhaling air from the outside, resulting in insufficient fuel combustion, thus Harmful gases such as carbon monoxide are produced, which is neither energy-saving nor environmentally friendly.

Contents of the invention

The purpose of the present invention is to provide a device capable of improving engine performance, accelerating engine exhaust gas emission, energy saving and environmental protection, and reducing exhaust emission noise.

The present invention is realized through the following technical solutions: the engine tail gas swirl exhaust pipe includes a connecting piece, a porous muffler pipe, an outer casing, blades and an air guide pipe. The connector is used to connect the exhaust pipe of the automobile; the porous muffler pipe is sealed with the connector, and an air inlet is formed between the porous muffler pipe and the outer shell; the blade is fixedly arranged on the air guide pipe, The blades are respectively fixedly connected with the porous muffler pipe and the outer casing; the air guide pipe is suspended and communicated with the porous muffler pipe.

Further, one end of the porous muffler tube connected to the connector is wedge-shaped, and a circular ventilation hole is provided at the rear end thereof.

Further, the two ends of the outer shell are trumpet-shaped, and the middle part is in the shape of a stepped truncated cone.

Further, the rear end of the air duct is trumpet-shaped, and 6 blades are evenly arranged on it.

Further, the surface of the blade is a smooth and irregular surface, on which two rows of circular ventilation holes are arranged, and the space angle between the left line and the right line of the blade is 15 degrees.

The outstanding advantages of the present invention are: the present invention can increase the inertial exhaust, increase the negative pressure suction, increase the air intake, thereby improving the fuel utilization rate, and can reduce the exhaust noise of the engine. At the same time, its structural design is reasonable and simple, and the cost is low. And easy to install and disassemble.

Detailed ways

As shown in the drawings, the engine exhaust swirl exhaust pipe of the present invention is mainly composed of a connecting piece 2, a porous muffler pipe 3, an outer casing 4, blades 5 and an air guide pipe 6. The connector 2 is used to connect the exhaust pipe of the automobile, the porous muffler pipe 3 and the connector 2 are sealed and connected, and an air inlet 9 is formed between the outer shell 4; the blades 5 are fixedly arranged on the air duct 6, and respectively It is fixedly connected with the porous muffler pipe 3 and the outer shell 4; the air guide pipe 6 is suspended in communication with the porous muffler pipe 3; Six blades 5 are evenly fixed on the trachea 6, and the tail ends are trumpet-shaped; the two ends of the outer shell are trumpet-shaped, and the middle part is stepped conical; The spatial angle is 15 degrees.

During operation, the exhaust gas from the engine enters the exhaust gas inlet 1, and a part of it is directional diverted through the circular ventilation holes 8 on the porous muffler 3, and evenly spreads to the blades 5, and the undivided gas passes through the air guide pipe 6 and is discharged through the exhaust gas outlet 7 ; When the car is running at a high altitude, the external air enters quickly through the air inlet 9, and the exhaust gas is quickly discharged by secondary pressurization; at the same time, the tail end of the air duct 6 is in the shape of an external horn to reduce noise to a certain extent; in addition, the outer shell 4 And air duct 6 tail ends are all trumpet-shaped, contribute to the discharge of tail gas.
