Under normal circumstances, 4S dealerships mortgage the vehicle certificate to banks for loans, which is why they inform car owners that the certificate has not arrived yet, preventing them from obtaining it on the spot. Below is a detailed introduction to the vehicle certificate: 1. Overview: The certificate is another important document for a car and is essential for vehicle registration. Only cars with a certificate meet the national requirements for motor vehicle equipment quality and related standards. 2. Function: The content of the two-dimensional barcode on the certificate is stored in ciphertext, using the DES-64 bit encryption algorithm. DES is a strong block cipher that repeatedly uses shift transformations and substitutions. It is a product cipher system with extremely strong resistance to decryption, effectively preventing the forgery of certificates.

What is the most effective way to clean a three-way catalytic converter?

Here are the methods for cleaning a three-way catalytic converter: 1. Non-disassembly cleaning with an IV bottle: The principle is to use the engine's own negative pressure to draw the three-way catalytic cleaning fluid from the intake vacuum tube. After combustion in the combustion chamber, it creates a high-temperature oxidation environment on the surface of the three-way catalytic converter. Through oxidation-reduction reactions, the chemical complexes blocking the three-way catalytic converter are decomposed into sulfur dioxide and carbon dioxide gases, which are then expelled, restoring the activity of the three-way catalytic converter. 2. Complete disassembly cleaning: This method is more thorough. After disassembly, the three-way catalytic cleaning fluid is directly poured into the three-way catalytic converter for soaking, allowing the blocked particles to dissolve in the cleaning fluid, which is then drained from the three-way catalytic converter.
