Description

Automotive catalytic converter structure Technical Field

[0001] This invention relates to a structure for an automotive catalytic converter, particularly a structure for an automotive catalytic converter that enables a gas to react fully with a catalyst. Prior Technology

[0002] Note that in gasoline-powered vehicles, exhaust gases are emitted. According to relevant regulations, untreated exhaust gases cannot be directly released into the atmosphere, otherwise it will cause pollution and fail the exhaust emission test. In the exhaust system, the exhaust gases often need to react with a catalyst to convert them into gases that are harmless or less harmful to the environment through chemical reaction. For vehicles, cost and volume are very important considerations. How to make the gases react fully with the catalyst to improve the conversion efficiency and reduce costs is an urgent problem to be solved.

[0003] Therefore, in view of this, the creator considered the idea of ​​creation, and designed it based on many years of experience. After extensive discussions, sample testing, and multiple revisions and improvements, this creation was finally launched. Summary of the Invention

[0004] This invention provides a catalytic converter structure for automobiles, which enables the gas to react fully with the catalyst, thereby improving conversion efficiency.

[0005]

[0006] Technical characteristics of problem-solving:

[0007] This invention provides a catalytic converter structure for automobiles, comprising a catalytic converter having a tubular outer shell containing a core. The core is made of metal and coated with a catalyst. The core is composed of three core units, each having an origin and a plurality of air vents distributed thereon. The three origins are arranged in a triangle. Each core unit rotates in the same direction around its origin and combines to form the core. The core unit is tilted such that the direction of the air vents is tilted relative to the axis of the outer shell.

[0008] The main purpose of this invention is that, because the direction of the air guide hole is inclined relative to the axis of the outer shell, and each of the three core units rotates in the same direction around the three origins, when the gas passes through the air guide hole, its direction is offset relative to the axis, thus forming a vortex. Furthermore, the inclination of the air guide hole increases the gas's movement path, which reduces the axial length of the core. The core is made of metal, which has better thermal conductivity. The three origins of the core unit are arranged in a triangular pattern, which allows the gas to be distributed more evenly in the core. All of these factors enable the gas to react more fully with the catalyst, thereby improving the conversion efficiency.

[0009] Other purposes, advantages, and novel features of this invention will become more apparent from the following detailed description and related drawings. Simple Explanation of the Diagram

[0017] To enable your review committee to gain a better understanding of the purpose, features, and effects of this work, the following examples, accompanied by simplified illustrations, are provided and explained in detail:

[0018] First, as shown in Figures 1 to 5, this invention provides a catalytic converter structure for vehicles, which includes a catalytic converter (10). The catalytic converter (10) has a tubular outer shell (11), and a core (12) is provided inside the outer shell (11). The core (12) is made of metal and coated with a catalyst. The core (12) is composed of three core units (121). Each core unit (121) has an origin (1211) and a plurality of air vents (1212) are distributed thereon. The three origins (1211) are in a triangular position. Each core unit (121) rotates in the same direction (clockwise or counterclockwise) with its origin (1211) as the axis and combines to form the core (12). The core unit (121) is tilted so that the direction of the air vents (1212) is tilted relative to the axis of the outer shell (11).

[0019] As shown in Figure 6, with the above structure, since the direction of the air guide hole (1212) is inclined relative to the axis of the outer shell (11), and each of the three core units (121) rotates in the same direction around the three origins (1211), when the gas passes through the air guide hole (1212), its direction is offset relative to the axis and rotates to form a vortex. The inclination of the air guide hole (1212) increases the movement path of the gas, which can reduce the axial length of the core (12). The core (12) is made of metal and has better thermal conductivity. The three origins (1211) of the core unit (121) are triangularly distributed, which allows the gas to be more evenly distributed in the core (12). All of these factors enable the gas to react more fully with the catalyst and improve the conversion efficiency.

[0020] As shown in Figure 3, this invention provides a structure for an automotive catalytic converter, wherein the core unit (121) is composed of several plates (A) and several wavy connecting parts (B). The connecting parts (B) are connected between each of the plates (A) to form the air guide hole (1212), thereby presenting a porous structure similar to corrugated paper.

[0021] This invention provides a structure for an automotive catalytic converter, wherein the three origin points (1211) are arranged in an equilateral triangle to achieve an equidistant effect.

[0022] This invention provides a catalytic converter structure for vehicles, wherein the housing (11) is cylindrical.

[0023] In conclusion, this creation has indeed achieved a groundbreaking structural design and possesses improved creative content. At the same time, it can achieve industrial applicability and progress. Furthermore, this creation has not been seen in any publication and possesses novelty. Therefore, it meets the relevant provisions of the Patent Law. Hence, we hereby file a utility model patent application and earnestly request the Examining Committee of the Bureau to grant legal patent rights. We are deeply grateful for your consideration.
