What does the DOT on tires mean?

DOT is the abbreviation for the U.S. Department of Transportation. The "DOT" marking indicates that the tire meets the safety standards set by the U.S. Department of Transportation. Here is an introduction to DOT: 1. The 11-digit number and letters immediately following "DOT" represent the tire's identification number or serial number. DOT is divided into three levels: A, B, and C, with Level C being the lowest, meeting only the minimum performance conditions specified by the U.S. Department of Transportation (DOT). The other two levels exceed the DOT requirements. 2. According to U.S. law, all tires sold in the U.S. market must pass DOT testing and have the DOT mark molded on the tire sidewall after certification. Tires without the DOT mark are not allowed to be imported, produced, or sold in the U.S. market. 3. The tires of these specifications produced by the company are currently only sold in the Chinese market and are not exported to the U.S., so the sidewall does not need to be molded with the DOT mark.

How Many Spark Plugs Does a Car Have?

Generally, a gasoline-powered car has one spark plug per cylinder, but there are exceptions. For example, the Nissan Bluebird U11 and Honda Fit 1.5 have two spark plugs per cylinder, meaning a four-cylinder engine in these models would have eight spark plugs. Below is an introduction to the types of spark plugs: 1. Standard Spark Plug: The insulator skirt is slightly recessed into the shell end face, and the side electrode extends beyond the shell end face. This is the most widely used type. 2. Extended Insulator Spark Plug: The insulator skirt is longer and protrudes beyond the shell end face. It has advantages such as high heat absorption and good anti-fouling performance, and it can be directly cooled by incoming air to lower temperature, reducing the risk of hot spots. Thus, it has a wide thermal adaptability range. 3. Fine Electrode Spark Plug: The electrode is very thin, featuring strong sparks and excellent ignition capability. It ensures quick and reliable engine starts even in extremely cold weather and has a wide thermal range, suitable for various applications. 4. Tapered Seat Spark Plug: The shell and threaded insert are conical, allowing good sealing without the need for a gasket. This reduces the spark plug's size, benefiting engine design. 5. Multi-Electrode Spark Plug: Typically has two or more side electrodes. Its advantages include reliable ignition and no need for frequent gap adjustments, making it suitable for gasoline engines where electrodes are prone to erosion and spark plug gaps cannot be adjusted regularly. 6. Surface Gap Spark Plug: Also known as a surface discharge type, it is the coldest type of spark plug, with a concentric gap between the center electrode and the shell end face.

What is the CMA Platform?

CMA architecture is a new framework jointly developed by Volvo Cars and Geely Auto, with Volvo Cars taking the lead. The new-era premium joint-venture brand Lynk & Co is built upon this architecture. This modular architecture can cover the development of vehicles ranging from A0 to B-segment, including sedans or hatchbacks, and even SUVs. Below is an introduction to the CMA architecture: 1. The modularity is reflected in the CMA architecture's component-based development of vehicle parts such as the body, chassis, power and drive systems, and electronic systems. Simply put, these components can be combined with each other. Therefore, if the development of these components maintains a high level of quality and compatibility, the assembled vehicle models will undoubtedly be of high quality as well. 2. The safety advantage of the CMA "Intelligent Magic Cube" lies in the close integration of active and passive safety technologies, providing stronger protection for vehicle occupants. Safety is also a major feature of the Lynk & Co brand, with all models adhering to stricter safety standards. The roof crush resistance can exceed 4.5 times the vehicle's weight. For reference: the Chinese standard requires exceeding 3 times the vehicle's weight, while the U.S. standard requires exceeding 4 times. Additionally, the 360° ultra-strong safety body structure meets the crash test standards of North America, Europe, and China.

How long does it take to start a car that hasn't been driven for a long time?

It takes about 5 minutes to start the engine. If a car hasn't been driven for a long time, the battery may be insufficiently charged. Warming up the car can help recharge the battery. There are three key points to note when leaving a car unused for an extended period: 1. Preparation before parking: Clean the exterior and interior of the car thoroughly before parking. Applying wax or a coating can help prevent corrosion of the paint. 2. Brake discs: For vehicles parked for a long time, it's best not to engage the handbrake too tightly. 3. Tires: To prevent deformation of the tires, the tire pressure should be slightly higher than usual. Increasing the tire pressure to around 2.8 can minimize damage to the tires.

How to Turn on the Teana Fog Lights?

Rotate the knob in the middle of the light control lever to turn on the Teana's fog lights. Below is some information about fog lights: 1. The purpose of fog lights is to attract the attention of other road users. 2. Fog lights are divided into front fog lights and rear fog lights, which also differ in color, with front lights typically being yellow and rear lights red. 3. Fog lights are characterized by their strong penetrating ability and do not produce diffuse reflection due to fog, which helps alert other vehicles and improves visibility during rainy or foggy conditions. Below are the regulations regarding fog light usage while driving: 1. When visibility is between 100-200m: Fog lights must be turned on, speed should not exceed 60km/h, and the distance from the vehicle in front should be kept at more than 100m. 2. When visibility is between 50-100m: Fog lights must be turned on, speed should not exceed 40km/h, and the distance from the vehicle in front should be more than 50m.

What is the Difference Between 95 Octane and 92 Octane Gasoline?

The main difference between 92 octane gasoline and 95 octane gasoline lies in their composition. Here are the key distinctions regarding the composition of 92 octane and 95 octane gasoline: 1. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. 2. The anti-knock substance in gasoline is isooctane. The ability of gasoline to resist knocking when burned in the engine is referred to as its anti-knock performance. The octane rating of 92 or 95 octane gasoline indicates its anti-knock performance—the higher the octane number, the higher the isooctane content, and the better the anti-knock performance. 3. Anti-knock performance refers to the ability of gasoline to resist knocking under various operating conditions. The anti-knock performance of automotive gasoline is expressed by its octane number. The higher the octane number, the better the anti-knock performance. The anti-knock capability of gasoline is related to its chemical composition. Branched-chain alkanes, as well as olefins and aromatics, generally have excellent anti-knock properties. Isooctane is assigned an octane number of 100, indicating good anti-knock performance, while n-heptane has an octane number of 0, indicating poor anti-knock performance. The octane number of gasoline is determined by an octane rating machine. High-octane gasoline can meet the needs of high-compression gasoline engines. The higher the compression ratio of a gasoline engine, the higher its thermal efficiency, which can save fuel. Increasing the octane number of gasoline mainly relies on adding high-octane components, but it can also be achieved by adding anti-knock agents such as MTBE.
