The Difference Between Sapphire Black and Carbon Black

The differences between Sapphire Black and Carbon Black are as follows: Light Reflection: Under white light, Sapphire Black emits a deep green glow, whereas Carbon Black absorbs light and reflects very little. Transparency: Sapphire Black appears slightly more transparent than Carbon Black. Texture: In sunlight, Carbon Black exhibits a deep blue hue, giving it a more textured appearance compared to Sapphire Black. Color Series: In BMW's domestic color series (both imported and domestically produced), the color representing 'black' is only coded as 'Sapphire Black,' which is a metallic paint. The color coded as 'Black' is a standard paint. Reflection and Transparency Differences: Under natural light refraction, Carbon Black displays a dark blue sheen, while Black only shows a deep black hue. Due to Black's light-absorbing properties, it hardly reflects any light. In terms of transparency, Carbon Black is relatively more transparent and offers a sense of space, whereas Black's spatial effect is less pronounced.

Can the passenger put their feet on the dashboard on the highway?

Placing feet on the dashboard while riding in the passenger seat on the highway won't result in a fine, but this behavior is extremely dangerous. Obstructing airbag deployment path: Putting feet on the dashboard directly blocks the airbag's deployment path. In an emergency, the airbag inflates at 320 km/h, potentially slamming the feet into the face with enough force to cause severe injury or even death. Additionally, if the airbag fails to deploy during emergency braking, the passenger might be ejected through the windshield. Risk of major accidents: If the passenger is asleep and sleepwalks, they might suddenly kick toward the driver's area or windshield, potentially causing a serious traffic collision.

Why can't the car key start the engine suddenly?

If the car key can be inserted and turned but the car won't start, it means the starter motor circuit is not connected. The reason could be that the contacts linked to the ignition switch rotation are burnt out or loose. Although the key is turned, the contacts are not connected, resulting in an open circuit. The car starting system consists of a battery, ignition switch, starter relay, and starter motor. The function of the starting system is to convert the battery's electrical energy into mechanical energy through the starter motor to start the engine. Insufficient battery starting capacity: In extremely cold regions, most cases of no response when turning the key are due to insufficient battery starting capacity. Due to climatic conditions, battery performance significantly declines in winter. If the battery has been in use for about 3 years and is nearing the end of its life, it should be replaced promptly. Similarly, engine oil is also affected to some extent, with poor fluidity in winter. It is recommended to warm up the car for a few minutes after starting and avoid high RPMs initially. Severe carbon buildup on spark plug electrodes: If there is severe carbon buildup on the spark plug electrodes, they can be removed and cleaned with a copper brush. Remember to place the removed parts in order and then reassemble them in reverse order.

Where to Place the National Flag on a Car?

Mostly attached to the left fender. It must be hung in the correct position to show respect for the national flag; otherwise, it may have the opposite effect, so caution is essential. If there is no suitable position, it's better not to hang it. Alternatively, you can choose to place a national flag sticker on the upper part of the front windshield where it doesn't obstruct the view, which is a way to respect the national flag. For cargo vehicles, adding windshields, water tanks, toolboxes, spare tire racks, etc., is allowed; interior decorations can also be enhanced. Small Flags Inside the Car: Small flags inside the car are generally placed in positions that do not compromise driving safety. Common locations include the car antenna, ABC pillars, or the ceiling for hanging. It is not recommended to place small flags on the car's suspension system as it may obstruct the driver's view. Although the intention stems from patriotism, there is no need to overdo it. Recommended Speed: After attaching the small flag inside the car, it is recommended to drive at speeds below 60 km/h in urban areas. Otherwise, the flag may easily fall off during vehicle operation.

Is Chaowei Battery Repair Fluid Effective?

Electric vehicle battery repair fluid does have some effect, but the results after repair are not ideal, it can only extend usage for a period of time. Battery Repair Fluid: Battery repair fluid, also known as lead-acid battery repair fluid, battery activator, or battery capacity enhancer, is a solution added to failed electric vehicle batteries. It can restore battery capacity, extend battery lifespan, and improve various battery performances. It does not require professional repair equipment and is simple to operate. Due to the different compositions of repair fluids, their repair effects also vary. How to Use Battery Repair Fluid: After adding battery repair fluid, the battery undergoes one complete charge-discharge cycle, and its capacity is restored, increasing the travel distance by 5-15 kilometers. After seven complete charge-discharge cycles, the battery capacity can be restored to over 90%, extending the lifespan by about one year. All batteries will experience various faults and failures after reaching a certain lifespan limit.

What is the diameter of a 15-24 tire?

15-24 tire diameter is 18. The calculation formula for car tire diameter is: Tire diameter equals rim diameter plus tire width multiplied by aspect ratio multiplied by 2. Since different vehicle models are equipped with tires of different size specifications, the diameter of car tires will also vary. Generally, the diameter range of tires is 60 to 80 centimeters. If you want to know the diameter of a tire, you first need to understand the size of the car tire. Tire usage precautions: Note that when the tire pressure is insufficient, check the air leakage area of the outer or inner tire. For tubeless tires, inspect the damaged area on the tire body and repair it promptly. The best repair method is to use a special cold patch for tubeless tires. Try to avoid using tire plugs and self-sealing liquids to prevent tearing and corrosion of the wound, which could lead to premature tire damage.
