What Can Be Extracted from a Three-Way Catalytic Converter?

A three-way catalytic converter can extract platinum group metals, as a car's three-way catalytic converter contains a significant amount of precious metals. Functions of the three-way catalytic converter: The three-way catalytic converter plays a partial role in noise reduction. If the three-way catalytic converter is hollowed out, the exhaust system is prone to generating various noises and resonance. Once hollowed out, the entire system loses its ability to purify exhaust gases, which can cause significant inconvenience during subsequent vehicle annual inspections. Composition of the three-way catalytic converter: It mainly consists of asbestos fiber felt, purifying agents, a substrate, and metals such as platinum, rhodium, and palladium. Among these, platinum, rhodium, and palladium are the primary catalysts in the three-way catalytic converter, effectively reducing the levels of nitrogen oxides and particulate matter in the exhaust.

What are the benefits of having smaller front wheels and larger rear wheels?

The benefits of having smaller front wheels and larger rear wheels include better climbing power, higher safety performance, and lighter steering for easier turning. Here are some precautions for using car tires: 1. Bulging: If bulging occurs on the tire, it needs to be replaced immediately; otherwise, it increases the risk of a blowout. 2. Tire lifespan: Tires are rubber products, and rubber products will age over time. Under normal conditions, tires installed on a car can last for four years. 3. Regularly check tire pressure: During regular use, it is also important to frequently check the tire pressure. The tire pressure should not be too high or too low. If the pressure is too high, it will reduce the contact area between the tire and the ground. If the tire pressure is too low, the tire may experience wave deformation during high-speed driving, increasing the risk of a blowout and potentially reducing the tire's lifespan.

Should I Give Up on New Energy for Personal Use?

It depends on your personal preference. Here is some relevant information about new energy: Definition: New Energy (NE): Also known as unconventional energy. It refers to various forms of energy other than traditional energy sources. These are energy sources that are just beginning to be developed and utilized or are actively being researched and awaiting widespread adoption, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. Characteristics: Abundant resources, generally renewable, and can be used sustainably by humans. They have low energy density, requiring larger spaces for development and utilization. Coal, petroleum, natural gas, and large to medium-sized hydropower are considered conventional energy sources, while solar energy, wind energy, modern biomass energy, geothermal energy, ocean energy, as well as nuclear energy and hydrogen energy, are classified as new energy sources.

What is the temp setting for cold air in a car?

In a car, temp 18°C is considered cold air. Below is relevant information about car temp: 1. Definition: Temp in a car refers to temperature, which can be adjusted via buttons. The temp button is generally located on the car's central console, and some models also have it at the rear air vents, allowing independent control of the rear air conditioning temperature. 2. Adjustment Method: There is a temperature adjustment knob on the car's dashboard, with one side red and the other blue. Turning it all the way to the red side produces hot air, while turning it all the way to the blue side produces normal temperature air. To get cold air, you also need to press the compressor AC switch to activate the cooling system and produce cold air.

Where is the license plate number Ji F from?

Ji F is the license plate number of Baishan City, Jilin Province. The following are the license plate numbers of other regions in Jilin Province: 1. Ji A Changchun City. 2. Ji B Jilin City. 3. Ji C Siping City. 4. Ji D Liaoyuan City. 5. Ji E Tonghua City. 6. Ji G Baicheng City. 7. Ji H Yanbian Korean Autonomous Prefecture. 8. Ji J Songyuan City. Additional information: 1. The first character of a license plate number is a Chinese character, representing the abbreviation of the province where the vehicle is registered. 2. The second character of a license plate number is an English letter, representing the code of the prefecture-level city where the vehicle is located. The general rule is: A is the provincial capital, B is the second largest city in the province, C is the third largest city in the province, and so on.

How much does tire pressure increase when driving on the highway?

Tire pressure increases by 0.4 to 0.6 bar when driving on the highway. The normal tire pressure temperature is between 2.2 and 2.4 bar, and tire pressure rises as the temperature increases. During high-speed driving, especially during emergency braking and rapid acceleration, tire temperature rises quickly. For every 10-degree increase in tire pressure temperature, the pressure increases by 0.1 bar. Therefore, maintaining tire pressure at the standard value helps avoid blowouts during high-speed driving and emergency braking. During long-distance driving, the tires generate heat from prolonged friction, and tire pressure increases in high-temperature environments. It is not advisable to lower tire pressure excessively to prevent blowouts, as excessively low tire pressure can also lead to blowouts. Low tire pressure increases the contact area between the tire and the ground, putting more pressure on the tire shoulders, which generates heat through internal friction, consumes the gas inside the tire, and damages its internal structure.

Can You Start in Third Gear?

You cannot start in third gear. Here are some related introductions about starting a car: Precautions for starting: Get in the car, fasten the seat belt, and adjust the seat. Quickly press the clutch to the bottom and shift into first gear. Turn on the left turn signal, check the surroundings (both side mirrors), and release the handbrake. Quickly lift the clutch to the semi-engaged position, pause slightly, then slowly lift the clutch while gently pressing the accelerator to start the car smoothly. Driving precautions: Do not keep the clutch in a semi-engaged state for a long time. Some drivers are accustomed to keeping their left foot on the clutch while driving, thinking it provides better control over the vehicle. However, this practice causes significant damage to the clutch plate. Especially when driving at high speeds, prolonged semi-engaged state will wear out the clutch plate rapidly.
