Why Are Three-Way Catalytic Converters So Expensive?

The high cost of three-way catalytic converters is due to the presence of precious metals in their honeycomb-structured substrate. Below are specific details about common failures of three-way catalytic converters: 1. Overheating: At normal temperatures, three-way catalytic converters do not possess catalytic capabilities. Their catalysts must be heated to a certain temperature to gain oxidation or reduction abilities. Typically, the light-off temperature for catalytic converters ranges between 250–350°C, while their normal operating temperature is generally between 350–700°C. During operation, higher-quality catalytic converters generate more heat, and oxidation temperatures also rise. When temperatures exceed 850–1000°C, the catalyst coating inside may detach, and the substrate can crack. 2. Chronic Poisoning: The catalysts are highly sensitive to elements such as sulfur, lead, phosphorus, and zinc. Sulfur and lead come from gasoline, while phosphorus and zinc originate from lubricating oil. These four substances, along with their oxide particles formed during engine combustion, easily adhere to the catalyst's surface, preventing contact with exhaust gases and thereby losing catalytic effectiveness—a phenomenon known as 'poisoning.' 3. Carbon Buildup: When a vehicle operates under low-temperature conditions for extended periods, the three-way catalytic converter cannot activate. Carbon deposits from the engine exhaust will accumulate on the catalyst's surface, blocking contact with CO and HC. Over time, this leads to clogged substrate pores, reducing conversion efficiency.

How is the mileage calculated?

The principle is actually quite simple: it involves multiplying the tire's rotation count by its circumference. Since the tire's circumference is fixed, knowing the wheel's rotation count allows calculation of the vehicle's mileage and speed. For example, if a tire has a circumference of 1 meter and rotates 1000 times per minute, the car would travel 1000 meters per minute, or 36 kilometers per hour. The main difference between various types of odometers lies in how they obtain the wheel rotation signal. Most vehicles use electronic odometers. The dashboard essentially functions as a display screen, with parameters controlled by the vehicle's computer. The speed sensor transmits the wheel rotation signal to the computer, which calculates a value based on pre-stored programs and displays it on the dashboard, continuously updating as the car moves. There are two methods for the speed sensor to obtain signals: one is from the transmission output shaft, and the other utilizes the ABS wheel speed sensor's signal. Most vehicle dashboards display two types of mileage: one is the total mileage the car has traveled, and the other is a measurable mileage that can be manually reset by the car owner. Next to most digital displays, there's a small button (cylindrical in shape) that can be held down to reset the measurable mileage.

Can unopened expired antifreeze still be used normally?

Unopened expired antifreeze cannot be used because the active ingredients in antifreeze will precipitate after expiration, causing the liquid to lose its antifreeze capability. At low temperatures, it will freeze and potentially damage engine components, radiators, and other cooling system parts. Antifreeze replacement cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze's condition—if it is insufficient, replenish it promptly. If suspended particles, sediment, or signs of deterioration or discoloration are observed, replace the antifreeze immediately and flush the system. Antifreeze composition: The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances. Types of antifreeze: Antifreeze is generally categorized into three types: ethanol-water, glycerin-water, and ethylene glycol-water.

Is it common for car doors to get paint chipped when opened?

Is it common for car doors to get paint chipped when opened. Precautions when opening doors: Before opening the car door, first observe the left and right rearview mirrors to confirm whether there are vehicles approaching from behind. For rear passengers, it is also necessary to remind the driver to help check the rear situation and only open the door to get off after ensuring safety. Park in a safe place, close to the right side of the road, ensuring no vehicles can come from the right side. Cyclists and pedestrians passing by parked vehicles, especially those that have just stopped, should maintain a lateral distance from the vehicle to guard against sudden door openings. Car paint maintenance: Rinse promptly after rain. Rain stains on the car body will gradually shrink, increasing the concentration of acidic substances in the rainwater. If not rinsed off with clean water promptly, the stains will damage the paint over time. For some special, extremely corrosive marks, remove them promptly. Special cleaning agents must be used for this purpose; avoid using blades to scrape or gasoline to remove them to prevent damage to the paint. Before, during, and after vehicle use, promptly remove dust from the car body to minimize the adsorption of dust by static electricity on the body.

Can Domestic Cars Run 300,000 Kilometers?

With the current mature technology, domestic cars can run 300,000 kilometers as long as they are maintained in a timely manner. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Below is the relevant introduction to car maintenance: 1. Exterior inspection: Before driving, check the doors, engine hood, trunk, and glass condition, inspect the car body for damage, whether the body is tilted, and if there is any oil or water leakage. 2. Engine and various fluids: Check the fixation of engine components, inspect the engine's joint surfaces for oil or water leakage. Check and adjust the tightness of the belt, inspect the fixation of various pipelines and wires. Check and replenish engine oil, coolant, and electrolyte. 3. Tires: Check the tire wear and clean the trunk. When approaching the tire wear mark, replace the tire. Inspect the tires for bulges, abnormal wear, aging cracks, or hard damage. 4. Cleaning and lubrication: Clean the oil stains on the engine hood, door, and trunk hinge mechanisms, and lubricate them. The general service life of antifreeze is 2 years, and it should be replaced during maintenance, thoroughly cleaning the cooling system. Due to the hygroscopicity of the braking system, brake fluid should be replaced every two years.

Where are Goodyear tires produced?

Goodyear's imported products are manufactured in Ohio, USA, while domestic products are produced in Dalian, China. The Goodyear Tire & Rubber Company was founded in 1898 and has a history of over a century. Goodyear is the world's largest tire manufacturing company, headquartered in Akron, Ohio, USA. The company primarily produces tires, engineered rubber products, and chemical products in more than 90 factories across 28 countries. Goodyear designs and supplies original equipment tires tailored to the specific requirements of major domestic automakers. It exclusively supplies tires for models including the BMW 3 Series, BMW 5 Series, older Audi A6 series, Peugeot 308, Peugeot 307, Peugeot 206, Changan Ford Focus, and Changan Ford Mazda 3 (production ceased in late February 2006). Additionally, Goodyear provides tires for numerous mainstream models such as the new Audi A6, Audi A4, Sagitar, Bora, Golf, Jetta, Passat, Santana, Chery Eastar, Zhonghua, Fukang, Elysee, Ford Fiesta, Haima Familia, Great Wall Haval, and Honda Civic. Following its ISO9002 certification in 1999, Goodyear's production facilities successively obtained QS9000 certification in April 2001, ISO14001 certification in December 2002, and TS16949 certification in March 2003.
