Why are Some Car License Plates Green?

Green license plates represent urban area-specific vehicles, namely new energy vehicles. The special logo for new energy vehicle license plates features a green background overall, with an electric plug pattern on the right side of the logo, and a colored section on the left resembling the English letter 'E,' symbolizing electricity and new energy. Nowadays, there are more and more new energy vehicles on the roads, primarily categorized into pure electric vehicles and hybrid electric vehicles. New energy vehicles refer to automobiles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices), integrating advanced technologies in vehicle power control and driving to form vehicles with advanced technical principles, new technologies, and new structures. These include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles.

How often should a car motor be replaced?

If the car motor is not malfunctioning or damaged, it does not need to be replaced. The car motor, also known as the starter motor, along with another motor called the idle motor, is generally quite durable. In daily use, if the driver does not operate the starter according to regulations, issues such as brush wear, poor contact of the electromagnetic switch contacts, damage to the one-way gear or flywheel gear, or poor grounding can lead to motor failure. Therefore, during regular vehicle use, drivers should pay attention to: 1. Maintain good starting habits to avoid burning out the starter; 2. Conduct regular battery checks to ensure the battery can start the engine under normal capacity and power; 3. Regularly clean the engine compartment to prevent dust and oil from corroding and aging the engine compartment wiring harness, which could lead to poor contact or rust at the starter interface and affect normal engine startup. If motor damage is detected, it should be promptly repaired and maintained.

What are the symptoms of a bad car wheel bearing?

The symptoms of a bad car wheel bearing include: 1. The wheel wobbles when the car is moving; 2. Unusual noises occur; 3. Poor rolling, leading to a decrease in power. Methods to diagnose a bad car wheel bearing: 1. Open the window and listen for sounds; 2. Increase the speed, shift to neutral, and let the vehicle coast to observe the noise; 3. Temporarily stop the car and check the temperature of the wheel hub; 4. Lift the car with a jack and manually rotate the four wheels quickly. Causes of a bad car wheel bearing: 1. Improper wheel installation; 2. Improper assembly or adjustment; 3. Poor lubrication; 4. Quality issues with the bearing itself.

How Often Should Car Filters Be Replaced?

Car filters should be replaced at the following intervals: 1. Oil filter: generally every 5,000 to 8,000 kilometers; 2. Fuel filter: generally every 10,000 to 20,000 kilometers; 3. Air filter: generally every 10,000 to 20,000 kilometers; 4. Cabin air filter: generally every 20,000 kilometers. There are four main filters in a car: the oil filter, fuel filter, air filter, and cabin air filter. Taking the oil filter as an example, it is installed in the oil passage. During circulation, the oil first passes through the filter to remove impurities before flowing to various lubrication points. This filtration process helps to better lubricate component surfaces and reduce friction. The lifespan of an oil filter depends on factors such as the material of the filter paper, filtration area, and strength. Higher-quality filter paper and a larger filtration area contribute to a longer lifespan. Typically, an oil filter lasts between 5,000 to 8,000 kilometers, but this should be determined based on the filter's quality, driving habits, vehicle wear conditions, and oil quality.

How to Identify the Maximum Speed Rating on Car Tires?

Car tires' maximum speed rating can be identified by looking at the letter following the numbers on the tire sidewall. Taking 195/65R1588H as an example: the letter H here represents the maximum speed rating. The speed rating of a tire is usually indicated by letters and numbers, showing the tire's maximum speed capacity under specified conditions while carrying the designated load. During driving, the vehicle speed must not exceed the tire's speed rating. This applies to all tires on the vehicle, including the spare tire, which should be inspected monthly. Methods for maintaining car tires: 1. Regularly check the tire surface for cracks or deformations; 2. Avoid sudden acceleration whenever possible; 3. Conduct periodic tire pressure checks.

What is the normal tire pressure for car tires?

Car tire pressure is normally between 2.3bar and 2.5bar. The hazards of low tire pressure: 1. Increased fuel consumption due to higher road friction coefficient; 2. Heavy steering wheel, prone to deviation, which is detrimental to driving safety; 3. Increased movement of various parts of the tire, causing abnormal heat due to excessive rolling; 4. Weakening of cord and rubber functions; 5. Damage to the tire bead area and abnormal wear. The hazards of high tire pressure: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, reducing driving comfort; 3. Accelerated wear of the tread pattern in the center of the tire; 4. Impact on the lifespan of other components; 5. Excessive stretching and deformation of tire cords; 6. Increased risk of tire blowout.
