Fog lights generally refer to automotive fog lights. Automotive fog lights are installed on the front and rear of a vehicle to illuminate the road and provide safety warnings during rainy or foggy weather, enhancing visibility for the driver and other traffic participants. Below is an introduction to fog lights: Rear Fog Lights: Rear fog lights are red signal lights installed at the rear of a vehicle, designed to make the vehicle more visible to other road users behind it in low-visibility conditions such as fog, rain, or dust. They emit a stronger light intensity than tail lights. Front Fog Lights: Front fog lights are mounted on the front of a vehicle, slightly lower than the headlights, and are used to illuminate the road during rainy or foggy weather. Due to reduced visibility in foggy conditions, the driver's line of sight is limited. These lights can extend the visible distance, especially yellow anti-fog lights, which have strong light penetration, improving visibility for the driver and other traffic participants, allowing oncoming vehicles and pedestrians to spot each other from a greater distance.

Is Engine Oil the Same as Gear Oil?

Gear oil is not engine oil. Gear oil, also known as transmission oil, is used in automotive transmissions. It is primarily composed of petroleum-based lubricating oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form a transmission lubricant. It is used to lubricate various gears in transmissions, reducers, and differentials to prevent gear surface wear, scuffing, sintering, etc., thereby extending service life and improving power transmission efficiency. Below is relevant information about engine oil: Engine oil is used in automotive engines and is a type of engine lubricant composed of base oil and additives. Depending on the base oil, it is classified into semi-synthetic oil, fully synthetic oil, and mineral oil. Inside the engine, it performs functions such as cleaning, lubricating, and cooling components. It operates in high-temperature and high-pressure environments for extended periods, requiring high oxidation resistance and stronger shear resistance.

Does a small car need to go through the inspection line in its 6th year?

Vehicles in their sixth year require on-site inspection during the annual review. More details are as follows: 1. If it's a new car purchased within the last 6 years, it can be exempt from inspection twice (requiring only the application for an inspection decal every two years, without the need for on-site vehicle inspection); in the 6th and 8th years, the vehicle must undergo on-site inspection. 2. For private cars over 10 years old, the original inspection cycle still applies, i.e., annual inspections for vehicles between 10 and 15 years old, and semi-annual inspections for vehicles over 15 years old. 3. The owner of the motor vehicle can apply for an inspection compliance decal at the vehicle registration authority within three months before the expiration of the current inspection validity period. Motor vehicle safety technical inspection institutions must inspect vehicles in accordance with the national motor vehicle safety technical inspection standards and bear legal responsibility for the inspection results. The quality and technical supervision departments are responsible for implementing measurement certification management for motor vehicle safety technical inspection institutions, verifying the inspection equipment, and supervising the implementation of national motor vehicle safety technical inspection standards.

How many seats can a C-class license drive?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses", a Class C1 license for small cars can drive manual or automatic transmission small and mini passenger vehicles with 9 seats or fewer (including 9 seats), as well as light and mini cargo vehicles (all small trucks with blue license plates), light, small, and mini special operation vehicles, and small automatic transmission cars (Class C2), low-speed cargo vehicles (Class C3), and three-wheeled vehicles (Class C4). Here is a related introduction about the differences between Class A, B, and C licenses: 1. Permitted vehicle types. Class A can drive large buses, tractors, and city buses; Class B can drive medium-sized buses and large trucks; Class C can drive small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled vehicles, and small automatic transmission passenger vehicles for the disabled. 2. Age restrictions for application. Those aged 21 or older can apply for city buses with a capacity of 10 or more passengers (Class A3); those aged 24 or older can apply for heavy and medium-sized full trailers or semi-trailers (Class A2); those aged 26 or older can apply for large passenger vehicles (Class A1). Those aged 21 or older can apply for medium-sized passenger vehicles (Class B1) or heavy and medium-sized cargo vehicles, large, heavy, and medium-sized special operation vehicles (Class B2). 3. Initial application age restrictions. The age for applying for a learner's permit for large buses and trolleybuses is 21 to 45 years; for large trucks, it is 18 to 50 years; for other vehicle types, it is 18 to 60 years. For those over 60 years old, the permitted vehicle types A, B, N, and P will be revoked. 4. Driving test passing standards. For Class C vehicles, a score of 80 or above is passing; for Class A and B vehicles, a score of 90 or above is passing. Tests for large buses, tractors, city buses, medium-sized buses, and large trucks include additional items such as simulated highways, continuous sharp mountain roads, tunnels, emergency handling, and narrow road U-turns. 5.

How often should the gasoline filter be replaced?

The gasoline filter is recommended to be replaced every 20,000 kilometers. The function of the gasoline filter is to remove water and impurities from the gasoline. When the engine is running, fuel flows into the sediment cup of the filter through the inlet pipe under the action of the fuel pump. Due to the increased volume and reduced flow velocity, water and impurity particles heavier than oil settle at the bottom of the cup, while lighter impurities flow with the fuel toward the filter element. Symptoms of a dirty or clogged gasoline filter include: 1. Slow response when accelerating; 2. Difficulty starting the car; 3. Needing 2 to 5 attempts to start the engine. Gasoline filters generally use microporous paper filter elements, treated with phenolic resin and formed into a folded cylindrical shape. They offer advantages such as good flow performance, high filtration efficiency, simple structure, low cost, and easy maintenance.

What does the N gear in a car represent?

The N gear in a car refers to neutral. N is the first letter of the English word "neutral," and in an automatic transmission car, it stands for neutral. This gear is used when temporarily stopping (e.g., at a red light). Note that this gear position indicates neutral, and to prevent the car from rolling on a slope, the brake must be pressed. Information about car gears is as follows: 1. Generally, there are six gear positions in an automatic transmission car, from top to bottom: P, R, N, D, S, L. 2. Driving an automatic transmission car using only the parking gear P, reverse gear R, neutral gear N, and drive gear D can fully meet the needs of general driving. However, if encountering some special driving environments, other functional gears may be required.
