link hidden, please login to view)
I. Concept of VOCs VOCs (Volatile Organic Compounds) • Environmental Impacts: • Atmospheric photochemical reactions generate ozone and secondary particulate matter • Nerve damage, long-term exposure can cause cancer ⸻ II. Working Principle of VOC Ceramic Catalysts 1. Oxidation and decomposition of VOC gases into harmless substances: • CO₂ (carbon dioxide) • H₂O (water) • Core reaction: Oxidation reaction (usually between 250–450°C) VOC + O₂ → CO₂ + H₂O 2. Catalyst Composition 1. Support Material • Commonly used ceramic honeycomb support (cordierite or alumina ceramic) • Characteristics: • High specific surface area (beneficial for catalyst dispersion) • High thermal stability • Corrosion resistance 2. Coating/Active Components • Noble metal catalysts: • Mainly platinum (Pt) and palladium (Pd) • Pt, Pd, or a Pt/Pd combination can be selected according to the type of VOC. • Non-precious metal catalysts: • Active oxides, such as MnO₂, Co₃O₄, CuO • Functions: • Provides oxidation active sites, accelerating VOC decomposition • Reduces reaction temperature, improving conversion efficiency 3. Working Mechanism
• Adsorption-Reaction-Desorption Mechanism: 1. VOC molecules are adsorbed on the catalyst surface. 2. Under the action of precious metals or active oxides, they undergo oxidation reactions with oxygen. 3. CO₂ and H₂O are desorbed from the catalyst surface. • Role of promoters/supports: • Ceramic provides high surface area and thermally stable structure. • Modifiable oxides (CeO₂, ZrO₂) can store oxygen, improving low-temperature oxidation capacity. ⸻III. Applications of VOC Ceramic Catalysts 1. Automobile exhaust treatment • 2. Industrial waste gas treatment • 3. 4. Chemical process exhaust gas • ⸻IV. VOC VOC conversion rate can reach over 90% High temperature resistance 600–800°C Low pressure drop honeycomb structure reduces exhaust gas drag and provides long lifespan. The noble metal catalyst is bonded to a stable support with a lifespan of 5–10 years. Customization is available, adjusting the Pt/Pd ratio or using non-noble metal formulations based on VOC type.

How to change the catalytic converter(shared by Shandong Xiaoyuan Environmental Protection Technology Co., Ltd, website:
link hidden, please login to view） I. Preparations Before Replacement 1. Safety Tools and Equipment: • Jack and support frame • Socket wrench, open-end wrench, universal joint • Non-slip gloves, safety goggles • WD-40 or other lubricant (to prevent bolts from rusting) • New catalytic converter (model matching original) 2. Vehicle Preparation: • Park on a level surface • Engage the handbrake • Ensure the engine is completely cooled (catalytic converter temperature is very high, easily causing burns) • Disconnect the negative terminal of the battery to prevent accidental triggering of the oxygen sensor alarm 3. Spare Parts: • New catalytic converter • New gasket • If damaged, the oxygen sensor (O2 sensor) may need to be replaced. ⸻II. Replacement Steps 1. Locate the Catalytic Converter • The catalytic converter is usually located after the exhaust manifold and before the muffler. • In diesel vehicles, it may be before the DOC and DPF. • Note the oxygen sensors before and after the catalytic converter; they need to be removed during replacement. 2. Remove the Oxygen Sensor • Use an O2 sensor socket or open-end wrench to unscrew it counterclockwise. • Be careful not to damage the sensor wiring harness.
3. Loosen the catalytic converter mounting bolts.
• The catalytic converter is usually fixed to the exhaust pipe with flange bolts.
• Spray lubricant on rusted bolts and wait 5–10 minutes.
• Use a socket wrench to loosen slowly, do not use excessive force to avoid breakage.
4. Remove the old catalytic converter.
• Remove it gently, being careful not to damage the exhaust pipe and suspension bracket.
• Check if the flange sealing surface is flat; repair any corrosion or deformation.
5. Install the new catalytic converter.
1. Install the new gasket (ensure alignment).
2. Install the new catalytic converter, first hand-tightening the mounting bolts to ensure correct positioning.
3. Then use a wrench to tighten evenly, avoiding overtightening to prevent flange deformation.
6. Reinstall the oxygen sensor.
• Use an O2 sensor socket wrench to screw it back on with moderate torque.
• Be careful not to twist the sensor wiring harness or allow it to come into contact with high-temperature components.
7. Check.
• Confirm that the catalytic converter is securely fixed and the oxygen sensor connection is normal.
• There are no obvious gaps in the exhaust pipe.
• Reconnect the battery negative terminal. ⸻III. Precautions 1. Avoid high-temperature operation: The catalytic converter's temperature can reach 400–600°C immediately after engine shutdown. 2. Ensure model compatibility: Different vehicle models have different catalytic converter apertures, lengths, and oxygen sensor interfaces. 3. Environmental requirements: Removed catalytic converters contain precious metals and should be recycled according to local regulations. 4. Engine fault codes (MIL): • After replacement, P0420 or similar codes may appear, requiring clearing the fault codes or waiting for self-learning. 5. Do not forcefully strike: The ceramic inside the old catalytic converter is fragile; avoid allowing fragments to enter the exhaust pipe. 6. Torque requirements: • Flange bolts are generally recommended at 20–40 Nm (depending on the vehicle model). • Oxygen sensor torque is generally 30–40 Nm. ⸻
Tips: • If the catalytic converter is only partially blocked, you can try cleaning or high-temperature regeneration first, but severe blockage still requires replacement. • For diesel vehicles, note that the catalytic converter after the DPF (DOC) and the oxidation catalytic converter are usually replaced or inspected together to ensure regeneration efficiency.

From raw materials to component parts, and even vehicle assembly, the changing face of the global automotive landscape is affecting the way U.S. buyers have been looking at their next vehicle purchase. It also has caused several OE manufacturers to revisit their own policies and marketing initiatives. Localization of manufacturing for U.S.-market vehicles has resulted in many European manufacturers putting down roots in areas more familar with NASCAR rather than the Nurburgring.
During the so-called “Malaise Era” (1973-1984), US-based vehicle quality declined significantly, giving Asian and European manufacturers a golden opportunity to capture the hearts and minds of many an American buyer. Initially, the Asian manufacturers cornered the economy market, with their inexpensive, reliable and fuel-efficient compact cars. European marques like BMW, Mercedes, Audi, Porsche, and even Volkswagen, became symbols of elevated status while maintaining reputations for precision engineering, impeccable quality and unmatched luxury.
Today, ever-changing economic policies have left some of these European manufacturers re-evaluating the parts and processes that allow them to continue offering their vehicles for sale in the U.S. Of the major European manufacturers, Jaguar Land Rover (JLR) is the only group that does not maintain an assembly plant on U.S. soil. Tariff announcements, coupled with an announced shift toward full electrification of the Jaguar lineup, have already hurt JLR’s profits in 2025, even before a cyber attack crippled assembly, parts distribution and dealership sales for five weeks this fall. The Germans have fared much better, with an established network of assembly plants throughout the southern U.S.
Volkswagen AG was the first of the Euro marques to build here, producing the Rabbit, Golf and Jetta during a 10-year tenure in Pennsylvania from 1978-’88. They decided to move south for their second attempt in 2008, choosing a location in Tennessee over options in Michigan and Alabama. Currently, Volkswagen AG builds only a few VW models in the U.S., including the Atlas, Atlas Cross Sport, and the all-electric ID4 at their present Chattanooga, TN, facility. The Scout nameplate, formerly associated with International Harvester, will soon be revived as an electric pickup and SUV platform when VW’s second domestic assembly plant opens outside of Columbia, SC, in 2027. Rumors of bringing future Audi and Porsche manufacturing to these plants have been swirling for most of the year.
South Carolina also has been the unlikely source of many beloved BMW models like the 3-Series and the Z3/Z4 roadsters since opening in 1994, and currently produces the X-Series SUVs for both U.S. and global distribution. It boasts the largest volume of any BMW facility worldwide. In addition to BMW’s Spartanburg vehicle assembly, South Carolina is home to Mercedes-Benz, with its Sprinter and eSprinter platforms assembled in Charleston. Mercedes also operates assembly and manufacturing facilities in Alabama, producing the GLE and C-Class, in addition to the EQS platform and its batteries.
BMW and Mercedes have been criticized in the past for advertising these vehicles as “Made in America,” when many of the components used to assemble these vehicles are sourced from global suppliers, and those models are also assembled in plants outside the U.S. This feels a bit unfair, given that the Big Three have a long history of producing vehicles beyond our own borders. We have already seen the introduction of Chinese-built Buick Envision and Lincoln Nautilus platforms, a host of Italian-built and designed Jeeps, and “American” pickups have regularly been manufactured in Mexico as well as Canada for decades. Volvo, an historically Swedish company with an assembly facility in South Carolina, is currently wholly owned by Geely, a Chinese holding company!
The globalization of our American automotive landscape, after 30 years of continuing growth and diversification, seems poised for a period of temporary stagnation as manufacturers, suppliers and buyers try to keep up with an ever-shifting marketplace. Uncertainty regarding the futures of ICE and BEV powertrains have led manufacturers as well as new vehicle buyers to pump the brakes a bit when it comes to making a commitment to future investments. In this period of unsettled economics and political turbulence, expect to see more companies choosing the relative safety of shorter supply chains and the localization of production for the diverse markets they serve.

Chase Elliott and the No. 9 link hidden, please login to view team qualified 17th for Sunday’s NASCAR Cup Series season finale at Phoenix Raceway. Elliott finished the first stage in 18th and followed that up with a 10th-place finish in the second stage. The 29-year-old driver led 30 laps in the final stage. Unfortunately, Elliott was issued a pit-road speeding penalty but still battled back for a 10th-place finish. Elliott and the No. 9 team ended the season with two wins, 11 top-five finishes, and 19 top-10s. Chase Elliott and the No. 9 NAPA Auto Parts team qualified 17th for Sunday’s NASCAR Cup Series season finale at Phoenix Raceway. After losing some ground on the initial start of the race, Elliott’s No. 9 NAPA Auto Parts Chevrolet’s handling started coming to him. He improved to 18th by lap 57, which is where he’d finish the first stage at lap 60.
After pitting for four fresh tires and fuel under the stage-ending caution, he lined up 18th to start the second stage on lap 69. He was scored 18th when the race was slowed for a caution on lap 72. Crew chief Alan Gustafson called Elliott in for four tires and fuel while some other teams opted to stay out. Elliott restarted 21st on lap 79 and was up to 13th when the caution flag was displayed on lap 106. After pitting for four tires and fuel, he restarted from the fifth row on lap 115 and was running in ninth when another incident brought out the yellow flag on lap 149. After a fast four-tire stop, Elliott was eighth to choose his lane for the restart, opting for the inside. Following the lap-155 restart, the 29-year-old driver continued to race inside the top 10, ending stage two in 10th.
During the stage break, Elliott brought the No. 9 NAPA Auto Parts Chevrolet to the attention of his crew for four tires, fuel and an air-pressure adjustment. Another fast stop by the team positioned Elliott out as the fourth car off pit road. He took the green flag for the final stage from the second row and held strong inside the top five. Elliott was running in third when the caution flag was displayed at lap 220. Once again, the team knocked out a fast four-tire stop, this time with Elliott winning the battle off pit road. He led the field back to the green flag on lap 226 and held onto the top spot until his Hendrick Motorsports teammate William Byron worked his way by on lap 253. When the caution flag was displayed next, Elliott was scored third. He pitted for four tires and fuel under the yellow and was the second driver off pit road; however, he was issued a speeding penalty.
Due to the loss of track position, the team opted to come back to pit road for a set of scuffs in order to save the fresh tires they had just put on. Elliott restarted 27th on lap 266 and was up to 26th at lap 278 when the yellow flag was displayed. This time, the team put its set of fresh tires back on the No. 9 NAPA Auto Parts Chevy. Elliott lined up 21st for the lap-284 restart and was 14th at the time of the final caution with just three laps to go. After pitting for right-side tires, Elliott chose the outside of row five for the overtime restart. He battled hard in the final two laps, taking the checkered flag in the 10th position.
On Sunday, Hendrick Motorsports secured its 15th Cup Series title, with Kyle Larson being the best-finishing Championship 4 driver.
Start / Finish: 17 / 10
Final Points Standing / Total: 8th / 2,310 pts.
