What is the difference between China 5 and China 6 vehicle emission standards?

Compared with the China 5 standard, the China 6 standard is more than 50% stricter overall. According to the "China 6" standard formulation instructions released by the Ministry of Environmental Protection, without considering the influence of test conditions and procedures, the CO emission limit for China 6a gasoline vehicles is 50% stricter than that of the China 5 standard. Here are some specific differences: 1. Price difference: China 6 vehicles are equipped with more components compared to China 5 vehicles. In addition, automobile manufacturers incur extra costs for vehicle declaration, various tests, and production, resulting in China 6 vehicles being significantly more expensive than China 5 vehicles. 2. Scrap time limit: While China 3 trucks from 2010 and China 4 trucks from 2010 can still operate in Beijing, many older vehicles are effectively scrapped as more cities impose driving restrictions. Therefore, even for vehicles of the same year, there will be differences in the time limit.

What Causes Water Leakage in the Audi A-Pillar?

Audi A-pillar water leakage causes: 1. Clogged sunroof drainage holes: When the sunroof drainage holes are blocked, rainwater that falls on the car cannot drain in time, causing water to flow along the conduit interface into the interior of the A-pillar. 2. Poor windshield sealing: After replacing the windshield, if the adhesive application is uneven, the car's sealing performance decreases, allowing rainwater to seep into the cabin through gaps. If the windshield hasn't been replaced, the issue is likely due to aging sealant causing leaks. 3. Aging window seals: Over time, the window sealing strips harden and age, reducing the window's sealing effectiveness. Additionally, improper handling of mounting holes when installing roof racks can also lead to water leakage.

Where Do Trade-in Vehicles Go?

If there is no official certified used car program, most of the vehicles accepted by 4S stores will be sold to used car dealers, and eventually these cars will enter the used car market. Below is the relevant introduction: 1. Used car trade-in: Used car trade-in refers to consumers using their current used car to exchange for a new car or a different model of used car, essentially combining the processes of selling the old car and buying a new car into one. The quality of used car trade-ins at 4S stores is guaranteed with minimal risk, which helps purify the market and enhance market competitiveness. 2. Advantages: Car owners only need to drive their old car to the 4S store, where an on-site evaluator can assess the price of the old car in about 20 minutes. After selecting a desired new car, the owner only needs to pay the price difference to complete the trade-in procedure. All remaining formalities are handled by the 4S store free of charge, and the new car trade-in process is typically completed within about a week.

Does driving a car in water without stalling have any impact on the vehicle?

There is basically no impact. Since water pressure is much lower than the exhaust pressure of the cylinders, as long as the vehicle does not stall, water will not flow back into the engine, so there will be no effect. Correct methods for driving through water: 1. If the car stalls in water, do not attempt to restart it immediately. Stalling in water can cause the engine to take in water, and after stalling, the car should only be towed to a repair shop in neutral gear for cleaning. 2. The water depth for small cars should not exceed 40 cm. The maximum wading depth varies among different vehicle models; generally, off-road vehicles can handle about 60 cm, while small cars should not exceed 40 cm. If observation shows that the water level is high, it is advisable to detour rather than force passage. 3. Do not accelerate when driving through water. You should maintain a steady speed with low gear and moderate to high throttle, rather than speeding through and splashing water. High speed can increase the actual depth of water the car passes through, causing rainwater to enter the cabin from the engine compartment or chassis.

Where is the brake located?

According to the different installation positions on the vehicle, parking brake devices are divided into two types: central parking brake devices and wheel parking brake devices. The brake of the former is installed on the transmission shaft, called the central brake; the latter shares a set of brakes with the service brake device and is installed on each wheel hub. The four parts of the wheel brake are as follows: 1. Brake wheel cylinder: The function of the brake wheel cylinder is to convert the hydraulic energy input from the brake master cylinder into mechanical energy to put the brake into working condition. 2. Brake caliper: When braking, the brake fluid flows from the brake master cylinder through the brake pipe into the brake caliper, and the brake fluid pushes the caliper to press the brake pads, thereby stopping the vehicle. 3. Brake disc: It rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force. When the brake is applied, it clamps the brake disc to slow down or stop the vehicle. 4. Brake pads: The working principle of braking mainly comes from friction. The kinetic energy of the vehicle's movement is converted into heat energy after friction by using the friction between the brake pads and the brake disc (drum) and the friction between the tires and the ground, thereby stopping the vehicle.

Is it necessary to apply for a highway ETC card?

It is necessary to apply for an ETC card. According to the regulations of the State Council, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. Additionally, newly installed ETC devices cannot be used on highways immediately; they need to be activated before normal use. During free holiday periods, vehicles with ETC can still use highways, and ETC users passing through ETC lanes will not be charged. ETC charging principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with banks, the purpose of paying tolls without stopping at road and bridge toll stations is achieved. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Green and low-carbon, vehicles passing through toll stations without stopping can reduce noise and exhaust emissions, minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: The efficiency of ETC lanes can theoretically increase by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interconnection of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a clear target in the "13th Five-Year" comprehensive transportation development indicators: "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, efforts will be made to promote ETC usage for trucks in the future. There will also be exploration of deep integration between ETC systems and smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications.
