New Description: [New Technology Field] This creation involves the installation of a catalyst system in front of the exhaust gas to the working temperature of the engine in a catalyst-to-discharge pipeline to advance the engine exhaust gas quickly [Prior Art] The engine will fix at least one scroll in the cylinder.:: Outside the mouth, there is a catalyst. The catalyst usually contains poplar (Pd), turn (8) (3) shell and medium Pd and pt elements to facilitate the exhaust gas. Harmful = two? Harmful C. 2 and H20, and the Rh element is good for purifying the engine γ χ (the secret compound you originally became harmless and 02, according to Yin Huayu waste milk, thereby reducing the impact of exhaust gas on the outside air quality. When the engine is started up, it is easy to generate too much harmful exhaust gas due to the fuel burning; however, due to the above-mentioned catalytic converter: 4: ϊ heating by the high temperature of the engine exhaust gas, and in the touch When the temperature is set, the energy can be oxidized to the engine. Therefore, the catalyst of the catalyst converter is emitted at the initial start of the engine, and the temperature is discharged. In the prior art, it has been disclosed that another front type catalytic converter is disposed on the exhaust gas exhaust pipe in front of the foregoing, so that the engine exhaust gas can first contact the front type catalytic converter, and the heating effect is generated. In addition, the catalyst of the 5 M336340 converter quickly reaches the working temperature when the bow is started. In addition, the closer the exhaust pipe is to the part of the engine, the narrower the pipe diameter; however, in order to make the engine exhaust first Connected with the catalyst In addition, the pre-type catalytic converter is generally disposed in the exhaust gas discharge pipe closer to the engine and has a narrower diameter; however, in the exhaust pipe with a narrow pipe diameter, the front type is arranged in the pipe. The catalytic converter causes the volume of the front-end catalytic converter to be limited, thereby limiting the surface area of the plate that provides the engine exhaust gas contact with the catalyst, resulting in a front-mounted catalytic converter. The catalyst Lurui board has a problem of poor heating efficiency of the engine exhaust gas; in addition, the conventional front type catalytic converter also fixes the core plate in the outer cylinder first, and then fixes the outer cylinder to the exhaust gas discharge pipe. Close to the position of the engine, it is obvious that the secondary plate is repeatedly fixed, which causes the problem of manufacturing the metal material of the outer tube, so it needs to be improved. [New content] In order to overcome the prior art, due to the front Type catalyst conversion product and its surface with catalyst. (4) The plate plate has poor heating efficiency for engine exhaust gas. 2: 1 thus 1^ is a catalyst plate for the catalyst conversion device. purpose In the mention of the other, there is a ##"""""""""""""""""""""""""""""""""" At least one catalyst is disposed in the manifold and the discharger, and the exhaust pipe is exhausted and silenced.

However, in order to further describe the present invention, and to exemplify the preferred embodiments, the details will be described later with reference to the drawings: [Embodiment] FIG. 1 shows a preferred embodiment of the present invention. The cross-sectional view of the catalyst conversion device of the present invention is included in the exhaust manifold 11 of the engine 1 and the exhaust front f 3 between the exhaust M336340 "f, the exhaust manifold 11, exhaust The front tube 3 is 9 connected to form an exhaust gas discharge pipe of the engine, and the muffler 2 is provided with at least one catalytic converter 4, wherein: the catalytic converter 4 is connected to the exhaust pipe 3 and at least one connecting tube 3〇 is connected in series to the silencer 2, and the catalytic converter 4 is covered with a catalyst such as palladium (pd), platinum (pt), • recording =); the muffler 2 has one end at one end The exhaust tail pipe 2ι, and the sound absorber 2 ^ are separated by a plurality of partitions 22, 23, and each of the partition plates 22, 23 is provided with a plurality of teeth 221, 231 for connecting the connecting pipe 30 and the catalytic converter 4 with the tail pipe 21. According to the above implementation environment, the present invention is provided with at least one catalyst-coated core plate 5 in the exhaust gas tube 3 adjacent to the exhaust manifold 11 (shown in Figures 2, 3 and 4) And one of the outer tube walls 31 of the exhaust front tube 3 is provided with at least one dry contact hole 32. In the present embodiment, two solder holes 32 are taken as an example to illustrate that each soldering hole 32 can be used for filling the solder 6. The core plate 5 is fixed in the inner tube wall 33 of one of the exhaust front tubes 3. In a more specific implementation, the present invention also includes: ???# The exhaust manifold 11 can be connected in this embodiment - the supply of the secondary air, the supply pipe 7 (shown in Figure 1); or, the supply pipe 7 It can also be connected to the exhaust gas front pipe 3 (as shown in FIG. 6), and the core plate 5 is disposed in the exhaust front pipe 3 between the supply pipe 7 and the muffler 2; the secondary air is driven by the engine 1 Intermittent negative pressure generated in the exhaust manifold Π and the exhaust front pipe 3 as a power source during operation, so as to guide the secondary air to be continuously supplied to the exhaust front pipe 3 and the muffler 2 via the supply pipe 7 .
