Standard requires that the brightness of low beams should not be less than 1000 lumens, and high beams should not be less than 1450 lumens. Additional information about automotive lighting is as follows: 1. Headlights: The primary purpose of headlights is to illuminate the road and objects ahead to ensure driving safety. They can also use the alternation between high and low beams as a signal for overtaking at night. Headlights are installed on both sides of the front of the vehicle, with either 2 or 4 units per car. The bulb power ranges from 45~60W for high beams to 25~55W for low beams. 2. Fog lights: Fog lights are installed near the headlights or slightly lower. They are used in low visibility conditions such as fog, snow, heavy rain, or dust to illuminate the road and signal to oncoming vehicles. The light is mostly yellow because yellow light has a longer wavelength, providing better penetration through fog. The bulb power is typically 35W.

What is the size of the Lingdong brake disc?

Lingdong brake disc is sixteen inches. The brake disc is a round disc that rotates when the vehicle is moving. When the brake is applied, the brake caliper clamps the brake disc to slow down or stop the vehicle. The brake disc is a very important component of the braking system, which can be divided into disc brakes, drum brakes, and air brakes. Structurally, it can be categorized into solid brake discs and ventilated discs, and by material, it can be divided into carbon fiber ceramic brake discs and metal brake discs. The maintenance methods for brake discs include: 1. Develop good driving habits; 2. Avoid emergency braking; 3. Regularly check the brake pads and brake discs; 4. Inspect the thickness of the friction pads; 5. Have a professional check the brake shoes; 6. Replace with original equipment manufacturer (OEM) provided brake pads and brake discs when necessary.

Why Does a Volkswagen Make Strange Noises When Going Over Speed Bumps?

When a Volkswagen makes strange noises while going over speed bumps, it is often due to the aging of the stabilizer link ball joints, which causes the noise when passing over speed bumps. Causes of the Noise: If the stabilizer link ball joints of the car show signs of aging, it can lead to strange noises when the car passes over speed bumps. Additionally, damage to the cushioning components on the chassis can also cause noise when the car goes over speed bumps. Solutions for the Noise: If you notice strange noises when driving over speed bumps, check whether the stabilizer link ball joints show signs of aging and address the issue promptly if they do. If you find that the cushioning components on the chassis are damaged, you should visit a 4S shop for replacement as soon as possible.

How Many Kilometers Should a Car Drive Before Cleaning Engine Carbon Deposits?

It is recommended to clean carbon deposits every 10,000 to 20,000 kilometers. The methods for removing carbon deposits and the hazards of engine carbon buildup are introduced as follows: Methods for Removing Carbon Deposits: Using an IV drip method: Cut off the fuel supply, connect a carbon cleaning agent to the engine fuel injector, and use the cleaning agent to soften the carbon deposits inside the engine so they can be burned and discharged. This method is only suitable for mild carbon buildup. Disassembling and cleaning the engine intake manifold: Remove the engine intake manifold, scrape off stubborn carbon deposits, clean it, and then reassemble it. Hazards of Engine Carbon Deposits: Engine carbon deposits can reduce engine power and increase fuel consumption. In severe cases, they can cause engine knocking, abnormal acceleration noises, damage to pistons and crankshafts, and even lead to engine oil burning, requiring major repairs.

How to judge the distance between cars for beginners?

Methods for beginners to judge the distance between cars: 1. The left one-third of the left rearview mirror and the right half of the right rearview mirror are danger zones for the following car; 2. If the following car is directly behind, when the inner rearview mirror can no longer see the wheels of the following car, it means the distance is less than 20 meters, and sudden braking should be avoided; 3. When the front of the car just touches the edge of the front car's tire, the distance should be about 5 meters; 4. When the front of the car aligns with the lower edge of the front car's bumper, the distance should be about 3 meters; 5. When the front of the car aligns with the front car's bumper, the distance should be about 1 meter; 6. If the front of the car aligns with the lower edge of the front car's license plate, the distance should be about 0.5 meters.

How Many Liters of Transmission Oil Should Be Added?

Transmission oil should be added approximately 4 liters. When replacing the transmission oil, the oil filter screen should also be replaced simultaneously. Precursors to transmission oil replacement include: 1. Vehicle shaking and gear shifting jerking; 2. The dashboard displays a transmission high-temperature warning; 3. The car stalls; 4. Unusual noises occur. The functions of transmission oil are: 1. Keeping the gear shifting system clean; 2. Lubricating the transmission device. Problems that may arise from insufficient transmission oil include: 1. Jerky gear shifting and unsmooth gear changes; 2. When pressing the accelerator, the increase in RPM does not correspond proportionally to the increase in speed—RPM increases normally, but the speed does not rise; 3. Severe cases may lead to transmission overheating and damage, as bearings lack lubrication, increasing the friction factor and making them prone to damage; 4. Noticeable noise, especially when driving at high speeds.

What are the differences between high-power and low-power engines?

Differences between high-power and low-power engines: 1. Different lifespan: The higher the engine power, the shorter its lifespan. Under the same model, the hardware structure of the engine is completely identical. The difference in power is actually determined by the turbocharger's boost intensity to achieve different power outputs, which results in higher fuel consumption and higher maintenance costs in the long run. Low-power engines have a longer lifespan, relatively lower fuel consumption, and lower maintenance costs. 2. Different prices: There is a significant price difference between low-power and high-power versions of the same model. Intuitively, low-power versions are relatively cheaper, while high-power versions are more expensive. 3. Different power: Drivers may feel a lack of power with low-power engines. From the perspective of engine wear, the difference in wear between the two is not significant. Although high-power engines deliver higher performance, the quality standards for engine component materials are also improved to handle prolonged high-load conditions.
