What is the rim width?

The rim size consists of two parameters: the bead seat diameter and the bead seat width. Common notations include 15x6.5; 15x6.5JJ; 15x6.5J; 1565, etc. There are no strict formatting rules. The first number "15" indicates the bead seat diameter, meaning the rim's bead seat diameter is 15 inches. The second number "6.5" represents the bead seat width, indicating the rim's bead seat width is 6.5 inches. When replacing rims, pay attention to the following parameters: 1. Center Bore (CB): Refers to the size of the rim's center hole. Although rims with different center bore sizes can be installed using adapters, this is not recommended for safety reasons. 2. Pitch Circle Diameter (PCD): For example, a rim with a PCD of 5x120mm means it has 5 lug bolts forming a circle with a diameter of 120mm. This value should also match the original specifications. 3. Offset (OFFSET): Also known as the ET value. A positive offset means the mounting surface is outside the centerline, while a negative offset means it's inside. Passenger cars typically have positive offset values, and this parameter significantly affects driving stability and cornering traction.

What Causes Carbon Buildup on Spark Plugs?

Spark plug carbon buildup can be caused by an excessively large engine ignition advance angle or improper spark plug selection. After cleaning, new spark plugs should be replaced. Steps for replacing spark plugs: Open the hood, lift the plastic engine cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. During removal, check for external debris such as leaves or dust and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage distributor wires in the firing order, then secure the cover. Spark plug replacement intervals: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. The following standards can be used as a reference for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

How to Solve the High Fuel Consumption of Ford Escort?

Here are the solutions for the increasingly high fuel consumption of Ford Escort: 1. Regular maintenance: Perform regular maintenance every 6,000 to 10,000 kilometers to reduce the accumulation of carbon deposits in the engine; choose gas stations with good fuel quality when refueling to prevent the intake manifold walls from becoming rough, which can affect the intake efficiency and mixture quality, leading to increased carbon deposits. 2. Regular carbon deposit cleaning: Conduct periodic carbon deposit cleaning every 40,000 to 50,000 kilometers, such as using drip cleaning, foam cleaning, hydrogen-oxygen decarbonization machines, or manual disassembly cleaning. 4. Regular spark plug replacement: The purpose of regularly replacing spark plugs is to use the electric spark generated by high voltage to ignite the air-fuel mixture. If the spark plugs are damaged, the ignition energy will decrease, causing uneven combustion of the mixture, which slows down acceleration and increases fuel consumption. 5. Frequently check tire pressure and tire wear: Frequently monitor tire pressure and tire wear. If the tire pressure is too low, the friction between the tires and the ground will increase, leading to higher resistance and increased fuel consumption. The normal tire pressure is around 2.5 bar, and it can be slightly reduced in summer.

Will speeding at 60 km/h in highway construction zones be captured for violations?

It will be captured but not penalized. According to regulations, temporary speed limits due to construction are considered special cases where violations are not enforced. For example, if the normal speed limit is 100 km/h but temporarily reduced to 60 km/h due to construction, you won't receive a penalty as long as you don't exceed 100 km/h. Speed and distance requirements under different visibility conditions during adverse weather such as rain, fog, sandstorms, or hail: When visibility is less than 200 meters: Turn on fog lights, low beams, outline marker lights, and front/rear position lights; maintain speed below 60 km/h and keep a distance of over 100 meters from other vehicles. When visibility is less than 100 meters: Turn on fog lights, low beams, outline marker lights, front/rear position lights, and hazard warning flashers; maintain speed below 40 km/h and keep a distance of over 50 meters from the vehicle ahead in the same lane. When visibility is less than 50 meters: Turn on fog lights, low beams, outline marker lights, front/rear position lights, and hazard warning flashers; maintain speed below 20 km/h and exit the highway at the nearest available exit as soon as possible.

Can I wear a necklace in my driver's license photo?

You can wear a necklace in your driver's license photo. Requirements for driver's license photos: The photo must be a recent (within 6 months) front-facing, full-color, bareheaded, single-person half-length small 1-inch photo of the applicant. Dimensions for driver's license photos: The photo size should be 3.2cm × 2.2cm, with the head length between 1.9cm to 2.2cm and the head width between 1.4cm to 1.6cm, on a white background. You cannot wear uniforms in the photo, and the image must be clear and natural. Below is an introduction to driver's licenses: 1. A driver's license is a "permit": Driving a motor vehicle requires certain driving skills. Without these skills, driving recklessly can lead to traffic accidents. Drivers without a license cannot drive on the road. However, for those who have mastered safe driving techniques, the document that permits them to drive vehicles on the road is the "driver's license." This indicates that a driver's license is a "permit." 2. Definition of a driver's license: Internationally, a driver's license is defined as "a document issued by the competent authority permitting the holder to drive a motor vehicle." In China, a driver's license is defined as "a legal certificate issued by the administrative authorities to individuals who have legally learned to drive a motor vehicle, mastered traffic regulations and driving skills, and passed the relevant tests, permitting them to drive a specific type of motor vehicle."
