Why Are Three-Way Catalytic Converters Valuable?

Because the catalysts on the ceramic substrate surface of a three-way catalytic converter are palladium and rhodium, which are rare elements with high prices. Here is some information about three-way catalytic converters: 1. A three-way catalytic converter is an external purification device installed on the car's exhaust pipe, located between the engine exhaust outlet and the muffler. Typically, there is an oxygen sensor in front of the catalytic converter and another one behind it. Vehicles with an engine displacement of 2.5 liters or more usually have two catalytic converters, either front and rear or left and right. 2. The internal structure of a three-way catalytic converter consists of: a stainless steel shell, a vibration damping pad (also called a mat), and a catalyst substrate (which can be either a honeycomb ceramic substrate or a metal substrate). 3. The working principle is: it converts harmful gases such as CO, HC, and NOx in the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions.

What does the 'Study to Reduce Points' mean in the Traffic Management 12123 App?

There are two possibilities for the 'Study to Reduce Points' in the Traffic Management 12123 App. Here are the specific details of these two options: 1. Passing the Exam: Motor vehicle drivers participate in road traffic safety laws, regulations, and related knowledge learning organized by the traffic management department of the public security authorities and pass the exam. 2. Participating in Activities: Drivers can apply to reduce traffic violation points by participating in traffic safety public activities in the jurisdiction where their motor vehicle driver's license was issued and meeting the relevant requirements. 'Study to Reduce Points' is a convenient traffic management measure uniformly deployed by the Traffic Management Bureau of the Ministry of Public Security. Starting from March 1st, Chongqing took the lead in piloting this measure nationwide. After its introduction, this measure will be implemented for the long term. Drivers can arrange their time reasonably to participate in 'Study to Reduce Points' based on their current point situation, avoiding network system congestion caused by a large number of people applying for online learning simultaneously, which could affect the learning experience.

How to Obtain an F1 Racing License?

To obtain a Super License, one must start with a domestic racing license. After participating in circuit training, you can acquire a Circuit C racing license. After competing in five races, you can upgrade to a B license. Upon winning a certain number of championships, you can then upgrade to an A license. With a domestic B license, you can participate in international competitions. Once all conditions meet the international Super License standards, you can apply to the FIA (Fédération Internationale de l'Automobile). Here is relevant information about the F1 license: 1. The F1 license is a special license issued by the FIA: "FIA Super License". 2. This driver's license is only awarded to outstanding drivers in F3000, F3, or CART series competitions. 3.

What Causes the Engine to Make a 'Tututu' Sound?

Here are the reasons for abnormal engine noise: 1. Aging or loosening of engine mounts: Engine mounts are rubber blocks placed between the engine and the frame. They are used to reduce vibrations during engine operation and secure the engine. Once the mounts age or loosen, the engine will shake, causing abnormal noise. 2. Engine misfire noise: An engine misfire mainly refers to one or more cylinders not working properly, typically manifested as intermittent exhaust gas flow, severe shaking of the exhaust pipe, and clearly audible abnormal engine noise. This phenomenon is closely related to ignition coil failure. 3. 'Knocking' noise: Due to poor lubrication conditions, excessive wear of pistons and cylinder walls leads to the clearance between them exceeding normal tolerance. During engine operation, the piston skirt impacts the cylinder wall, producing a clear 'clanging' sound, which is more noticeable at idle or low speeds. 4. Overly rich air-fuel mixture: When the engine's air-fuel mixture is too rich, symptoms include difficulty starting the engine, uneven operation, black smoke from the exhaust pipe, abnormal engine noise, and sometimes backfiring. 5. Carbon deposits and clogged filters: This results in decreased engine power and increased fuel consumption.
