The reason for recycling three-way catalytic converters is that they contain many rare metals. These metals have the potential for recycling and reuse, so to avoid waste, there are specialized individuals who recycle three-way catalytic converters. Appearance: The three-way catalytic converter looks like a metal can from the outside, but inside it has a 'substrate' for purifying exhaust gases. This honeycomb-shaped ceramic substrate is coated with a precious metal slurry, primarily composed of platinum, rhodium, and palladium. Function: The precious metals act as catalysts, reducing hydrocarbons (HC) and carbon monoxide (CO) in the exhaust into water and CO2, while breaking down nitrogen oxides (NOx) into nitrogen and oxygen. This is the exhaust purification function of the three-way catalytic converter.

How to Clean Dirt on the Radiator?

You can use a radiator cleaner to perform the cleaning. The specific steps are as follows: 1. Park the vehicle and turn off the engine. Wait for the coolant temperature to drop, then open the expansion tank and add the radiator cleaner; 2. Start the engine and let it idle for 5-10 minutes after the cooling fan activates; 3. Turn off the engine and remove the front bumper. Ensure all fastening screws are loosened before slowly detaching it from both ends toward the center, being careful not to break the clips; 4. Once the coolant has completely cooled, drain the radiator cleaner along with the old coolant, then refill with new engine coolant.

How to Lock the Trunk of Roewe i5?

To lock the trunk of the Roewe i5, close the trunk lid and then lock the car using the central locking system. This will successfully lock the trunk. Once the central locking is engaged, the trunk lid cannot be opened. Additionally, ensure that the trunk lid is securely closed before attempting to lock it, otherwise, the trunk lid cannot be locked. Relevant information about the Roewe i5 is as follows: 1. Exterior Design: Features the Roewe family's rhythmic floating wing wide-body grille design, paired with rectangular front headlight clusters. In terms of dimensions, the car measures 4601mm in length, 1818mm in width, and 1489mm in height, with a wheelbase of 2680mm. 2. Powertrain: The Roewe i5 is equipped with either a 1.5L naturally aspirated engine or a 1.5T turbocharged engine, delivering maximum power outputs of 120Ps and 169Ps, and maximum torque outputs of 150N·m and 250N·m, respectively. 3. Transmission: The 1.5L engine is paired with a CVT advanced continuously variable transmission, while the 1.5T engine is matched with a 7-speed TST intelligent dual-clutch transmission.

Which is more suitable for a new car: coating or crystal coating?

New cars are more suitable for crystal coating. Here is the relevant content introduction: 1. Crystal coating provides reliable paint surface sealing technology for car paint, offering efficient and long-lasting protection to prevent environmental impacts on the paint color. 2. The method of crystal coating is as follows: (1) Conduct a comprehensive and detailed inspection of the vehicle for any scratches or paint peeling. Wash the car with neutral car shampoo in the order from front to back and top to bottom, and carefully wipe the body with a soft towel. (2) After repeatedly kneading the clay, place it in the palm of your hand and move it horizontally back and forth on the paint surface with water, using adhesive tape to protect different parts of the car body. (3) Depending on the actual condition of the paint surface, select an appropriate polishing compound for polishing, rinse the entire car carefully with water, and dry the paint surface with an absorbent towel and an efficient dry cleaning gun. (4) Use a special degreasing solution to degrease the paint surface, while cleaning and caring for the paint surface condition, edges, door edges, engine compartment, car glass, and tires. (5) Confirm that the entire vehicle's construction is completed without errors.

Is License Retention Credible?

License retention is not credible; it's just a pretext for recruitment. The full name of a driver's license is a motor vehicle driving license, also known as a 'driver's license,' which is a certificate required by law for motor vehicle drivers. Driving a motor vehicle requires certain driving skills, and those lacking such skills may cause traffic accidents if they drive recklessly. Generally, people cannot drive on the road without a license. Below are the classifications of driver's licenses: A1 License: Can drive large buses and A3, B1, B2, C1, C2, C3, C4, M. A2 License: Can drive tractors and B1, B2, C1, C2, C3, C4, M. A3 License: Can drive city buses and C1, C2, C3, C4. B1 License: Can drive medium-sized buses and C1, C2, C3, C4, M (medium-sized buses refer to those with fewer than 19 seats, such as minibuses and vans).

What to Do When the Car Hood Won't Open?

Solutions for when the car hood won't open are as follows: 1. There is a hood button under the car's steering wheel. Pulling it usually loosens the hood. Lift the hood, reach inside, and flip a mechanical latch to open it. 2. Crawl under the car and use a wire to reach the hood lock hole from below the engine to release the front hood. Below are the functions of the hood: 1. Airflow guidance. For objects moving at high speed through air, the air resistance and turbulence generated around them directly affect their trajectory and speed. The hood's shape can effectively adjust the direction of airflow relative to the car's movement and the resistance it generates, reducing the impact of airflow on the car. Through guidance, air resistance can be decomposed into beneficial forces, increasing the front wheels' grip on the ground and enhancing driving stability. 2. Protection for the engine and surrounding components. Under the hood are critical parts of the car, including the engine, electrical circuits, fuel lines, braking system, and transmission system. Enhancing the hood's strength and structure can effectively prevent adverse effects such as impacts, corrosion, rain, and electrical interference, ensuring the vehicle's proper operation. 3. During driving, the driver's front visibility and natural light reflection are crucial for correctly judging road conditions. The hood's shape can effectively adjust the direction and form of reflected light, reducing its impact on the driver. 4. The engine operates in a high-temperature, high-pressure, and flammable environment, risking explosions, fires, or leaks due to overheating or component failure. The hood can effectively block damage from explosions, acting as a protective shield.
