What procedures are required when purchasing a car?

First, go to the insurance company to pay the insurance premium (some can be completed directly at the 4S store); pay the vehicle and vessel tax and vehicle purchase tax; drive to the vehicle management office for license plate registration, after which the traffic police will inspect the vehicle identification code, appearance, warning triangle, etc. Choose a license plate number online or at the vehicle management office. After selecting the number, retrieve the annual inspection label and the license plate receipt. Once the license plate is obtained, install it on the car and affix the annual inspection label and other required marks. Documents needed for car purchase: 1. Full payment purchase: Fewer documents are required for full payment purchase—only an ID card is needed to complete the purchase via cash or card payment. 2. Loan purchase: Loan purchase is slightly more complicated. You need to prepare copies of six major documents: ID card, income proof (household registration or temporary residence permit, etc.), property ownership certificate, marriage certificate, residence proof, and driver's license. If you are an individual business owner, you must also provide copies of relevant documents such as tax registration certificate, business license, and organization code certificate.

Why are pop-up headlights banned?

The reason for banning pop-up headlights is to protect pedestrian safety and reduce hazards during driving. Here is more relevant information: 1. Pop-up headlights: This refers to a hidden headlight design where the lights are recessed into the vehicle's front hood when turned off, and flip upward when activated. Not just the AE86 and RX-7, many classic car models adopted this "pop-up headlight" design. 2. Hazards of pop-up headlights: This design increases the vehicle's drag coefficient, leading to higher fuel consumption. Additionally, the mechanism requires extra mechanical components which carry higher failure risks. For modern increasingly popular xenon lights, the internal space of pop-up headlights is too cramped, making it difficult to install related xenon light components inside.

What are the causes of low cylinder compression pressure?

Cylinder compression pressure being too low is mainly caused by air leakage between the cylinder head and the cylinder. Here is some related information about cylinder compression: 1. Compression ratio: The engine compression ratio refers to the degree to which the engine's air-fuel mixture is compressed, expressed as the ratio of the total cylinder volume before compression to the cylinder volume after compression (i.e., the combustion chamber volume). 2. Cylinder function: The cylinder is a cylindrical metal component that guides the piston to perform linear reciprocating motion inside it. In an engine cylinder, air converts thermal energy into mechanical energy through expansion; in a compressor cylinder, gas receives compression from the piston to increase pressure.

Where to Take the Subject 4 Exam?

Subject 4 is taken at the Vehicle Management Office. The exam standards for Subject 4 are as follows: 1. Subject 4 Exam (also known as the Safe and Civilized Driving Knowledge Test): Conducted after passing the road test. According to the Ministry of Public Security's Order No. 123, there is no official term 'Subject 4'; the formal name is 'Safe and Civilized Driving Knowledge Test.' However, most driving schools and trainees refer to it as Subject 4 to distinguish it from the Subject 3 road test. 2. Subject 4 Exam Question Bank: Starting from January 1, 2020, the Ministry of Public Security released the first version of the Subject 4 question bank, which includes 700 questions for small vehicle licenses (C1, C2, etc.) and 1,023 questions for large vehicle licenses (B2, A2, etc.). 3. Second Version of the Subject 4 Question Bank: From May 1, 2020, the Ministry of Public Security updated the question bank to its second version, adding 100 questions for small vehicles (totaling 800 questions), while the large vehicle question bank remained unchanged. The current latest version is the May 2020 edition, and the exam question bank is uniformly used nationwide.

Which is better for car refueling, 92 or 95?

The octane rating of gasoline for a car should be based on the recommendation in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it on the fuel tank cap, which will be clearly marked. Generally, the fuel grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the application of new technologies, the octane rating cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower octane gasoline. This is because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the octane rating, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is significantly lower, the reduced ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance can make the engine run very unstably. If the knocking is imperceptible, it may only increase noise without obvious damage to the engine. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

Are electric vehicles subject to traffic restrictions based on license plate numbers?

Electric vehicles are a new type of energy-efficient and pollution-free vehicle, which are highly favored. They are only subject to traffic restrictions on certain road sections but not based on license plate numbers. Here is some extended information about electric vehicles: 1. Electric vehicles: Also known as electric-powered vehicles, they are divided into AC electric vehicles and DC electric vehicles. Typically, electric vehicles use batteries as their energy source, converting electrical energy into mechanical motion through components like controllers and motors, with speed controlled by adjusting the current. 2. Based on power sources, they can be categorized into: pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, and fuel cell vehicles. 3. Based on how electricity is supplied, they can be divided into: those that connect to an external power source for electricity; and those that use fuel cells or energy storage devices (such as storage batteries or supercapacitors) as their power source.
