Is It Necessary to Keep a Spare Tire in the Car?

Is it illegal to modify the steering wheel?

Modifying the steering wheel is not illegal. Here are specific details about illegal modifications: 1. Spoilers are not allowed: As components that enhance vehicle stability, spoilers are more suitable for high-speed, large-displacement models. However, many car owners opt for aluminum-magnesium alloy spoilers, which increase the overall weight of the vehicle. The prominently raised spoiler also increases air resistance, leading to higher fuel consumption. When installing a spoiler, avoid blindly choosing overly large ones just for aesthetics. 2. Wheel rims are not allowed: Wide and flat tires used with large rims can effectively reduce lateral sway and improve handling and stability. Many car owners prefer the largest possible rims, but it's important to note that flatter tires have poorer shock absorption, significantly reducing driving comfort. Additionally, when changing tires to match new rims, avoid tires with a total diameter differing by more than 3 cm from the original tires, as this can increase fuel consumption, reduce acceleration power, and even cause the tires to rub against the wheel arch edges when turning fully, leading to abnormal wear and misalignment. 3. Exhaust pipes are not allowed: Beyond personalizing the vehicle's appearance, another goal of car modification is to enhance speed performance. Some owners who haven't modified the engine believe that installing large-diameter exhaust pipes not only makes the vehicle's 'roar' more impressive but also provides stronger power.

What is the National VI Standard?

It refers to National VI, which is the China 6 emission standard. Below is a detailed introduction about the China 6 emission standard: 1. Implementation Time: Starting from 2019, various cities and regions across China have gradually begun implementing the China 6 standard, which is known as the strictest emission standard ever. Initially, the China 6a standard was implemented, which is not very strict, while China 6b is the true China 6 standard. The China 6a standard was implemented as a transitional standard from China 5 to China 6, and the China 6b standard is expected to be officially implemented in 2023. 2. Differences Between China 6 and China 5 Emission Standards: In the China 6b phase, most indicators are 50% stricter compared to the China 5 standard. According to estimates, under the China 6 emission standard, the emissions of carbon monoxide, hydrocarbons, non-methane total hydrocarbons, and nitrogen oxides from light-duty gasoline vehicles will be reduced by approximately 50% compared to the China 5 phase, and particulate matter emissions will be reduced by about 40%. For heavy-duty diesel vehicles, nitrogen oxides and particulate matter will be reduced by more than 60% compared to the China 5 phase. Considering that vehicle exhaust accounts for 20%~40% of air pollution in first-tier cities, implementing the China 6 standard can lead to a significant improvement of over 10% in urban air quality.

What to Do When a Motorcycle Overheats Severely?

Motorcycle overheating can be addressed with the following solutions: 1. Engine Oil: Lack of oil or using inferior-quality oil can lead to poor lubrication and overheating. Misalignment of the engine cylinder piston rings can cause scraping and overheating. Prepare the fuel mixture according to the specified ratio, and ensure the gasoline engine's lubrication oil is not insufficient. 2. Forced Air Cooling: Check whether the cooling system is forced air or natural air cooling (scooters typically use forced air, while regular motorcycles use natural cooling). For forced air cooling, inspect if the fan is damaged (replace if necessary). 3. Lean Fuel Mixture: If the carburetor's fuel mixture is too lean, the engine may overheat. Check the spark plug for signs of burning. Clean the cooling fins or remove carbon deposits. Avoid using industrial cleaning gasoline without anti-knock additives.

Is it okay to only buy compulsory traffic insurance for a new car?

It is permissible to only purchase compulsory traffic insurance for a vehicle, as this is the only insurance mandated by the state for road use. Without it, according to the "Road Traffic Safety Law," the traffic management authorities of the public security organs are required to impound the motor vehicle, notify the party to provide the corresponding license, certificate, or mark, or complete the necessary procedures, and may issue a warning or impose a fine ranging from 20 to 200 yuan. Compulsory Traffic Insurance for Automobiles: The full name of compulsory traffic insurance is "Compulsory Liability Insurance for Motor Vehicle Traffic Accidents." It is a mandatory liability insurance where the insurance company compensates for personal injury, death, and property losses (excluding vehicle occupants and the insured) caused by road traffic accidents involving the insured motor vehicle within the liability limits. The premium is based on a nationally unified standard, but the price varies depending on the vehicle type, primarily influenced by the number of seats. Compared to the over 20 exemption clauses in commercial third-party insurance, compulsory traffic insurance covers a much broader range, including losses caused intentionally by the victim, the insured's own property losses, related arbitration and litigation costs, and some indirect losses from accidents. Moreover, regardless of whether the insured vehicle is at fault in an accident, compulsory traffic insurance will compensate within the liability limits without any deductible or exemption. Introduction to Electronic Insurance Policies An electronic insurance policy refers to a digital policy issued by an insurance company using digital signature software compliant with the PKI system and an enterprise digital certificate, bearing the electronic signature of the insurance company. An insurance policy, abbreviated as a policy, is the formal written proof of the insurance contract between the insurer and the insured. It must fully record the rights, obligations, and responsibilities of both parties to the insurance contract. The contents of the insurance policy serve as the basis for both parties to fulfill the contract. The insurance policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof marks; Time-saving and convenient, unrestricted by time or location, with information universally accessible online anytime, quickly and easily; Allows for reissuance or resending, eliminating concerns about loss. If a paper version is needed offline, it can be printed or mailed; Facilitates management, as electronic standardization makes it easier for insurance companies and traffic police departments to manage the insurance information of various vehicles.

What Causes Car Paint to Turn Matte?

When a section of car paint turns into a matte surface, it is usually caused by dirt accumulation on the body, resulting in a rough texture. This can be addressed by polishing and waxing the car body. Below is an introduction to related content: 1. Smooth and glossy paint surface: Polishing utilizes physical means such as cutting, combined with abrasive media, to remove unevenness on the paint surface, thereby achieving a smooth and glossy finish. 2. Polishing: Polishing is a process that removes surface irregularities from the paint. To achieve a more even surface, a portion of the paint is removed, allowing the paint to reflect light at a greater angle, making it appear shinier and brighter.

Can the wax streaks on a car be washed off?

Yes. The methods to deal with wax streaks on a car are as follows: 1. Eraser: Use an eraser to rub the areas with dried wax residue, which can remove the wax, but the effect is limited and only works for wax that is not very sticky or in small amounts. 2. Degreaser: Degreaser, commonly known as wax remover, can be poured onto a towel and then rubbed on the areas that need cleaning to remove the wax. 3. Gasoline or alcohol: Like degreaser, gasoline and alcohol can dissolve car wax, and the operation method is the same. Additional information: Car waxing is relatively simple, and many car owners do it themselves. However, for those who are waxing for the first time, uneven application or incomplete wiping of the wax can lead to streaks, which is quite normal. Wax streaks on a car can look unsightly, but they can be washed off because the wax will gradually wear away over time and with washing. If you don’t want the streaks to remain, simply wash them off. If they don’t come off in one wash, a few more washes will do the trick.
