Original headlight codes are typically located at the bottom left or right corner of the headlight. Below is a detailed guide on identifying genuine headlights: 1. Inspect the edges of the headlight for numerous imperfections. 2. Check if the gap between the installed headlight and the car body is even: significant vertical deviations often indicate aftermarket products with inferior manufacturing standards and poor tolerance control, whereas original headlights perform better in this aspect. 3. Aftermarket headlights exhibit poorer illumination: they may have longer response times and uneven brightness distribution between upper and lower beams. Additionally, you can verify authenticity by examining the headlight code at the bottom left or right corner.

How many points are deducted for failing the annual inspection?

Failing the annual inspection will result in a deduction of 3 points. The consequences of overdue vehicle inspection are as follows: Safety cannot be guaranteed: Vehicles that do not undergo annual inspections on time cannot ensure driving safety. Insurance companies are not responsible: For any traffic accidents caused by vehicles that have not undergone annual inspections on time, the parties involved will bear full or primary responsibility, and the insurance company will not be responsible. This is because the insurance policy specifies that vehicles with expired inspections are among the objects of claim rejection. Mandatory scrapping: It is particularly important to note that according to the 'Regulations on the Compulsory Scrapping Standards for Motor Vehicles', if a motor vehicle fails to obtain the inspection qualification mark for three consecutive inspection cycles (three annual inspections) after the expiration of the inspection validity period, it will be forcibly scrapped.

What Causes Turbocharger Abnormal Noise?

The causes of turbocharger abnormal noise include: damage to the turbocharger (such as seized rotating shaft or impeller scraping the housing), leading to metal friction and abnormal noise; leaks in the intake or exhaust pipes, or cracks in the intercooler causing pressurized gas leakage. Below is related information: Other reasons: Bypass valve diaphragm rupture, causing pressurized gas leakage; burrs or protrusions on the inner wall of the housing, generating noise when high-speed airflow passes; accumulation of dirt in the turbocharger diffuser section. Symptoms of metal friction noise in the turbocharger: black smoke from the exhaust, decreased power, and abnormal noise from the turbocharger. Metal friction noise: If there is a metal friction noise, it is caused by excessive wear of the turbocharger rotor bearings or thrust bearings, resulting in friction between the impeller and the turbocharger housing. If the noise is not metal friction but rather an airflow sound, it is due to the high-speed rotation of the turbocharger rotor producing rotational noise, or leakage at the intake or exhaust connections due to poor sealing.

Can You Start the Car While Charging an Electric Vehicle?

You can start the car while charging an electric vehicle. Below are the specific details about electric vehicles: Concept: An electric vehicle (BEV) refers to a vehicle powered by an onboard power source, using an electric motor to drive the wheels, and meeting all the requirements of road traffic and safety regulations. It operates using electricity stored in batteries. When driving the car, sometimes 12 or 24 batteries are used, and sometimes more are required. Types: Electric vehicles are categorized into Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Fuel Cell Electric Vehicles (FCEV). Power Source: The power source provides electrical energy to the drive motor of the electric vehicle, which converts the electrical energy into mechanical energy. The most widely used power source is the lead-acid battery. However, with advancements in electric vehicle technology, lead-acid batteries are gradually being replaced by other types due to their low energy density, slow charging speed, and short lifespan. Emerging power sources under development include sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, fuel cells, and other new types of power sources.

Can a car still be driven after 12 years?

A car that has been used for 12 years can theoretically continue to be used as long as it is not damaged. New regulations implemented: Since May 1, 2013, the new regulations for phasing out and scrapping old vehicles have been implemented, with the scrapping age limit for private cars abolished and a mandatory scrapping at a maximum mileage of 600,000 kilometers. The regulations state that small and micro non-operational passenger vehicles, large non-operational cars, and wheeled special machinery vehicles have no usage age limit. The new regulations for the scrapping age of household cars, as officially issued by the Ministry of Commerce in the "Mandatory Scrapping Standards for Motor Vehicles," abolish the mileage age limit for non-operational cars and set the mileage limit for private car scrapping at 600,000 kilometers. Strict regulations: This method of abolishing the age limit and instead using mileage as the standard greatly improves the utilization rate of cars. Calculating based on a normal annual usage of 20,000 kilometers, the usage period of private cars is almost doubled. Although the age limit is abolished, it does not mean that any vehicle can truly reach 600,000 kilometers. The new policy has imposed stricter regulations on vehicle usage standards.

What is the reason for the car fan not rotating at low speed but rotating at high speed?

Car fan not rotating at low speed but rotating at high speed may be due to a damaged thermostat, abnormal circulation of the vehicle's cooling system, causing the temperature control switch to malfunction, which can also lead to this situation. The last possible cause is a faulty engine coolant temperature sensor. Below are additional details: Principle: When the coolant temperature is below 70 degrees, the thermostat remains closed. At this point, the engine's cooling system only has a small circulation loop, without a large circulation loop. This means the water from the engine's outlet pipe passes through a small bypass pipe directly into the cylinder head for internal circulation. Specific reasons: At this stage, the coolant does not pass through the radiator. As the temperature continues to rise to nearly 80 degrees, the thermostat gradually opens until it is fully open. Then, the engine's coolant flows through the main outlet pipe to the radiator before entering the cylinder head for large circulation. If the engine temperature continues to rise, the temperature-sensitive switch installed on the thermostat cover or radiator will activate the fan's low-speed switch, causing the fan to rotate at low speed and draw air from front to back for cooling.
