What is a car's head-up display?

HUD stands for Head-Up Display, which translates to a head-up display in Chinese. It uses augmented reality technology to project vehicle or road condition information onto the display (primarily the windshield). Different types of HUDs project varying data information such as speed, time, and engine status. Most HUDs use innovative phosphors to project information onto the windshield via lasers. Some HUDs also integrate transparent screens to display critical information. After installing an HUD head-up display in a car, it ensures the driver's safe and stable driving, allowing more focus on observing the road and driving, thereby improving driving safety for each trip. Head-up displays can be categorized into suspended and dashboard types. Suspended HUDs are fixed on the sun visor above the driver, which results in the HUD information being projected onto the upper area of the windshield. Dashboard-type HUDs are fixed on the center console in front of the driver, which determines that the HUD information will be projected onto the front area of the windshield. Cars equipped with head-up displays include: BMW 5 Series Li, Peugeot 3008, Peugeot 508, Audi A6, Audi A7, Lexus GS, and Land Rover Vision concept car, among others.

How to Deal with Car Paint Bubbling?

If the bubbling area of the car paint is small, you can choose to touch it up with the same color paint. If bubbling occurs in multiple parts of the car body, the best solution is to repaint the entire car; otherwise, it will significantly affect the car's appearance. Here are some related car paint maintenance tips: 1. Wash your car regularly. Relying on rain to clean your car is a misconception, as the impact of rainwater on the paint accumulates over time. Initially, it may seem harmless, but prolonged exposure will accelerate paint damage. The correct approach is to rinse your car after rain and wipe it dry. 2. Waxing, glazing, and paint coating can effectively protect the car paint. 3. If substances like asphalt, bird droppings, or chewing gum stick to the paint, clean them off promptly to prevent further corrosion.

What are the reasons for difficult cold engine start?

The reasons for difficult cold engine start can be summarized in the following 5 points: 1. Low engine temperature: The temperature inside the engine is insufficient, and both fuel and lubricant temperatures are too low. Therefore, more fuel should be injected during cold starts to meet power requirements. Poor fuel atomization at low temperatures leads to reduced ignition energy, affecting power output and causing the vehicle to shake. 2. Excessive carbon buildup on valves and intake passages causing cold start difficulties: When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making ignition difficult. Only when the carbon deposits become saturated with gasoline will the engine start more easily. After starting, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction, making the air-fuel mixture too rich. This fluctuation between lean and rich mixtures causes rough idling after a cold start. 3. Faulty coolant temperature sensor: If the engine temperature is -10°C during a cold start but the sensor "tells" the ECU that "the current temperature is 20°C," the ECU will inject fuel based on 20°C conditions, leading to engine shaking. 4. Untimely spark plug replacement: Cold starts require higher ignition energy. After a certain mileage, the electrode gap of spark plugs widens, and when it exceeds the standard, the spark energy generated will significantly weaken, making it unable to properly ignite the air-fuel mixture in the cylinder (commonly known as misfire). 5. Faulty ignition coil: The ignition coil is a transformer responsible for converting the vehicle's low-voltage current into high-voltage electricity, enabling the spark plug to "generate sparks" with sufficient voltage. Once the ignition coil fails, such as due to cracking or leakage, it will result in insufficient or lacking spark plug ignition capability. Consequently, the air-fuel mixture in that cylinder will not combust properly, leading to engine misfire, difficult starts, and acceleration shaking.

What materials are required for vehicle transfer procedures?

The specific documents required for vehicle transfer are as follows: Documents the seller needs to prepare for vehicle transfer procedures: Original ID card and one copy of the original owner (or agent) (for corporate entities, the original and copy of the organization code certificate); Original vehicle registration certificate and one copy; Original vehicle license and one copy; Original purchase invoice (or previous transfer invoice) and one copy; Vehicle purchase tax payment certificate; Documents the buyer needs to prepare for vehicle transfer procedures: Original ID card of the new owner and three copies, or original ID card of the agent and one copy (for corporate entities, the original and copy of the organization code certificate); Vehicle registration, transfer, cancellation form / transfer application form; For cities with purchase restrictions, an original personal passenger car quota certificate and three copies are required; If the buyer is a non-local resident applying for a local license plate, a valid temporary residence permit is also required. Vehicle transfer first requires a vehicle evaluation, where the price is assessed based on the overall condition and age of the vehicle. The original commercial insurance can be canceled (compulsory insurance cannot be canceled), or the insurance can be transferred to the buyer at the insurance company. Precautions when purchasing a used car: Incomplete documentation. Complete used car documentation includes: vehicle registration certificate (or original purchase invoice), vehicle license, vehicle purchase tax payment certificate, road maintenance fee records, and compulsory insurance. Missing vehicle registration certificates or licenses, or unpaid compulsory insurance or road maintenance fees, can cause endless trouble for the buyer. Therefore, if the seller cannot provide complete documentation, the buyer should be particularly cautious. Tampering with the odometer. Most consumers rely on the odometer to judge a car's condition, and sellers often take advantage of this by tampering with the odometer. The odometer is not just a record of usage intensity but also an indicator of when other vehicle components were repaired or replaced. If the buyer follows the maintenance schedule based on a tampered odometer, it can lead to a series of potential safety hazards. New paint covering 'injuries.' When buying a used car, if the car has been repainted and there are signs of repair around the front, rear, or A, B, and C pillars, the car may have been in a major accident. 'Tuning the heart' to raise the price. Many buyers focus too much on the car's 'heart' (engine) and overlook the health of the body. Used car sellers exploit this by replacing engine components to make the 'heart' appear younger and thus increase the price.

How to Find the Engine Number of a Car?

The engine number is usually found on the outer surface of the engine block, on the vehicle's nameplate, or on the nameplate inside the engine compartment. You can also check the engine number on the purchase invoice, the factory certificate of compliance, the operating permit for commercial vehicles, the vehicle purchase tax payment certificate, the registration records with public security authorities, or the vehicle insurance card. The simplest and most direct method is to look at the vehicle's administrative green book or the vehicle's registration certificate. The engine number is like a person's ID number, representing each vehicle. It contains very important information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine. It is used to indicate information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose vehicles are required to display the professional manufacturer's name, model, and production number. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's lineup, and multiple engines can share the same model. The engine number, however, refers to the production number of the engine, and each engine has a unique number. Composition of the Engine Number: Front Section: Includes the product series code, generation symbol, and regional or corporate code. Manufacturers can choose the appropriate letters as needed, but they must be approved and recorded by the industry standardization unit. Middle Section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear Section: Comprises symbols for structural features and usage characteristics. End Section: Distinguishing symbol. If differentiation is needed due to improvements or other reasons within the same series, the manufacturer can choose an appropriate symbol. The rear and end sections can be separated by a hyphen.
