What Causes the Jerking When Refueling a Natural Gas Vehicle?

Natural gas vehicle jerking during refueling can be attributed to the following reasons: Natural gas vehicles often experience backfiring: Backfiring is caused by an overly lean air-fuel mixture, which can result from various factors. These include improper adjustment of the mixer leading to a lean mixture, lack of regular maintenance causing air leaks in the intake manifold and resulting in a lean mixture, and prolonged driving on mountainous or uneven roads that displace the air filter covers, allowing excessive air to enter the cylinders and creating a lean mixture. Insufficient power in natural gas vehicles: When converting a vehicle to run on natural gas, the original engine structure remains unchanged to accommodate both fuel and gas conditions. As a result, the vehicle's power output typically decreases when using natural gas, usually by about 5-15%.

How Long Can You Use Temporary License Plates Before Switching to Permanent Ones?

You can switch to permanent license plates as soon as they are issued. Temporary license plates are valid for 15 days and can be renewed up to three times, allowing a maximum usage period of 45 days. Within these 45 days, you must install the permanent license plates. Vehicle License Plate Application Process: The applicant must bring the required materials to the local vehicle management office to complete the necessary procedures. The inspection department will review the vehicle's factory qualification certificate for domestically produced vehicles. The registration review department will examine the submitted materials, input the registration information if everything complies with regulations, and issue an acceptance certificate to the vehicle owner. The archives management department will verify the information in the computer registration system, organize the documents, and file them. Rules for Using Temporary License Plates: Before the permanent license plates are issued, only temporary license plates should be used. Once the permanent plates are issued, even if the temporary plates are still within their validity period, they cannot be used anymore. If caught by traffic police, you will face corresponding penalties.

Is Waxing Good for Cars?

Waxing is beneficial for cars. Benefits of waxing: The primary functions of waxing include waterproofing, protection against acid rain, effectively preventing paint aging, anti-static properties, dust resistance, and more. Additionally, car wax can provide a polishing effect. It prevents static electricity in cars, which can be caused by synthetic fibers or silk fabrics, as well as friction with dust particles in the air. Regardless of the source, static electricity can be troublesome for drivers. Therefore, car wax not only prevents static electricity but also effectively blocks the friction damage caused by air and dust on the paint surface. Drawbacks of waxing: It can wear down the paint surface over time. Long-term waxing essentially means gradually wearing down the paint, as waxing involves polishing with microscopic particles. It is prone to oxidation because car wax uses petroleum as a solvent, making it susceptible to oxidation, which means it cannot provide long-term protection for the car paint once oxidized.

What is the Difference Between All-Season Tires and Regular Tires?

The difference between all-season tires and regular tires lies in their appearance: all-season tires have an "AT" marking on the tread, while regular tires have wider tread grooves, offering better drainage, making them more suitable for use in rainy summers. All-season tires, also known as multi-purpose tires, are designed to adapt to various road conditions and are often used in complex and demanding environments. Below is some relevant information about tires: 1. Function: Tires are one of the key components of a vehicle, directly in contact with the road surface. Together with the vehicle's suspension system, they help absorb shocks during driving, ensuring a comfortable ride and smooth handling. They also maintain good traction between the wheels and the road, enhancing the vehicle's traction, braking, and off-road capabilities. 2. Classification: Vehicle tires can be categorized by their use into passenger car tires and truck tires. Passenger car tires are mainly used for inflatable tires on passenger vehicles, while truck tires are designed for trucks, buses, and trailers. Based on their structure, vehicle tires can also be divided into pneumatic tires and solid tires. Most modern vehicles use pneumatic tires, while solid tires are only used on low-speed vehicles or heavy-duty trailers operating on main roads with asphalt concrete surfaces.
