Is it allowed to modify the appearance of the exhaust pipe?

1 Answers

No, it is not allowed to modify the appearance of the exhaust pipe, as this constitutes illegal modification and will result in failure to pass the annual inspection. Requirements for vehicle annual inspection: Do not make large-scale alterations to the vehicle's appearance. Do not illegally modify the vehicle, ensure all window glass is intact and free of reflective sunshade film, ensure all lights and instruments are complete and functional, ensure the braking performance is good, ensure the vehicle is equipped with a fire extinguisher and reflective warning triangle, and maintain consistent tire tread patterns. Any changes to the vehicle's appearance must be reported to the traffic police department and the vehicle management office of the public security bureau. Modified vehicles must obtain a new vehicle license. Reasons why modifying the exhaust pipe appearance is not allowed: Modifications such as altering the intake and exhaust systems, widening the body, lowering the chassis, changing brake components, or blindly upgrading high-beam headlights, which change the vehicle's technical parameters, are illegal and will not pass the annual inspection according to regulations. No individual or organization is permitted to engage in the following activities: assembling a motor vehicle or altering its registered structure, construction, or features without authorization; changing the motor vehicle model, engine number, chassis number, or vehicle identification number; forging, altering, or using forged or altered motor vehicle registration certificates, license plates, driving licenses, inspection compliance marks, or insurance marks; or using another motor vehicle's registration certificates, license plates, driving licenses, inspection compliance marks, or insurance marks.

Is it serious if the coolant warning light comes on in the car?

It is serious if the coolant warning light comes on in the car. The cooling system warning light (red) indicates that the coolant temperature is too high or the coolant level is too low. Engine overheating: The air in the antifreeze generates a lot of foam when stirred by the water pump, which can hinder the heat dissipation of the water jacket wall. Calcium and magnesium ions in the water slowly form scale at certain high temperatures, significantly reducing the heat dissipation capacity. At the same time, it can also cause local blockage of the water channels and pipes, preventing the antifreeze from flowing normally. The engine components expand due to heat, disrupting the normal fitting clearance, affecting the cylinder's air intake, reducing power, and diminishing the lubricating effect of the engine oil. Coolant level too low: The normal operating temperature of the engine is around 90 degrees. If the water temperature is too high, it may be caused by insufficient coolant in the antifreeze reservoir. It could also be due to too much water mixed into the antifreeze. The function of the antifreeze is to help cool the entire radiator system. When it is lacking or there is too much water, the engine may "boil over."

What batteries are currently used in pure electric vehicles?

Currently, pure electric vehicles use ternary lithium batteries and lithium iron phosphate batteries. Ternary Lithium Battery: Also known as ternary polymer lithium battery, it uses graphite material for the negative electrode and nickel-cobalt-manganese oxide (NCM) or nickel-cobalt-aluminum oxide (NCA) materials for the positive electrode. The ternary composite positive electrode material can adjust the ratio according to actual needs. Compared with lithium iron phosphate batteries, it has higher energy density, smaller battery size, and better low-temperature performance. Lithium Iron Phosphate Battery: Since lithium iron phosphate is used as the positive electrode material, it is called lithium iron phosphate battery. Its raw materials are low-cost, and the thermal control temperature of lithium iron phosphate batteries is relatively high, generally above 500 degrees. Therefore, compared with ternary lithium batteries, lithium iron phosphate batteries have relatively stronger stability. The most important advantage of lithium iron phosphate batteries is their long service life, and their charge-discharge cycle times are better than those of ternary lithium batteries.

Why Do Older Cars Consume More Fuel?

Old cars have higher fuel consumption due to sensor damage. There are various sensors near the engine, such as the water temperature sensor, oxygen sensor, intake air temperature sensor, air flow sensor, and knock sensor. If any of these sensors malfunction, the car's fuel consumption will increase. The most common scenario is a damaged oxygen sensor, which leads to increased fuel consumption. The normal operation of a car engine relies on sensors. Issues like engine carbon buildup, sensor problems, or engine malfunctions can prevent the engine from working properly. With advancements in automotive manufacturing technology, mechanical components rarely suffer from severe failures, while the probability of electronic system failures is relatively higher, especially in older cars. The oxygen sensor needs replacement and cannot be used indefinitely. Engine carbon buildup increases over time. Many old cars have never had their carbon deposits cleaned, leading to significant carbon buildup in the engine. Carbon deposits have an adsorption effect. If gasoline is adsorbed by carbon deposits after injection, the engine will lose power, increasing fuel consumption. Engine wear also contributes to higher fuel consumption. As usage time increases, the engine will experience wear and tear. When the engine cylinder walls wear out, the gap between the cylinder and piston rings increases. During the power stroke, explosive combustible mixtures can leak through the gap between the cylinder and piston rings, reducing vehicle power and increasing fuel consumption.

Can a car battery at 10V still be used?

A car battery at 10V can still be useful if it can be recharged, because a 12V battery cannot be used anymore when it drops below 10.5V and must be recharged. A fully charged battery measures 14.8V, and after resting for two days, it stabilizes at 12.15V. Battery Introduction: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. It is primarily made of lead and its oxides, with sulfuric acid solution as the electrolyte. The normal service life of a car battery ranges from 1 to 8 years, largely depending on the vehicle's condition. Under normal circumstances, where the vehicle's alternator charges properly and there are no electrical leaks or grounding issues, the battery can typically last more than 3 years. Precautions: If you notice that the battery is not holding a charge, the starter is weak, or the headlights are significantly dimmer, the battery should be removed and charged for 12-24 hours using a battery charger. If the problem persists and the vehicle's mileage exceeds 50,000 KM, and the alternator is functioning correctly, it may be time to consider replacing the battery.

Can a vehicle pass the annual inspection with the ABS light on?

Can a vehicle pass the annual inspection with the ABS light on? The annual inspection of a vehicle is not related to the ABS light being on. As long as the headlights are bright enough, all the lights are functioning, and the brakes are working properly, it can pass. Steps for vehicle annual inspection: For vehicles that are 6 years old, an annual inspection is required. You need to go to a testing station, pay the fee, and undergo an exterior inspection, exhaust emission test, and safety technical inspection. After passing all these tests, you will receive the results, which will be signed and uploaded by the staff. After review, the annual inspection compliance sticker will be issued. Notes on vehicle annual inspection timing: During the annual inspection, the owner of the vehicle can apply for the inspection compliance sticker from the local vehicle management office within 3 months before the expiration of the vehicle's inspection validity period. For vehicles within six years of registration, every two years, within the two months before the initial registration month (totaling three months), all traffic violations must be handled. After that, bring the required documents to the nearest traffic police station's annual inspection window to fill out the form and receive the annual inspection compliance sticker.

How to Choose the Right Car: Essential Knowledge

Before buying a car, you need to determine the type of vehicle you want. When selecting a car model, consider your budget and needs. If you only need it for commuting, opt for a fuel-efficient, durable, and low-maintenance car. If you frequently go on road trips or enjoy driving for leisure, an SUV might be a better choice. If you prioritize performance and handling, consider a sports car. For families or those who often travel with multiple passengers, an MPV (multi-purpose vehicle) is ideal. Once you've narrowed down your preferred models, visit several dealerships to compare prices and promotions. It's advisable to shortlist a few models, test-drive them at dealerships, and then choose the one that best suits your needs. Always test-drive a car at a dealership before purchasing—don't rely solely on specifications. Some cars may not have the most powerful engines but offer an excellent driving experience. Conversely, some vehicles with strong engines may perform poorly in real-world conditions. During a test drive, pay attention to the suspension's ability to absorb bumps, noise insulation, and interior space to ensure it meets your expectations.
