To check the national emission standard of a vehicle, the simplest and most direct method is to look at the vehicle's environmental protection label. You can also inquire through the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center. Below is relevant information about vehicle emission standards: 1. Meaning of vehicle emission standards: Vehicle emission standards refer to regulations on the content of harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) emitted from vehicle exhaust. 2. Meaning of National VI: The National VI Motor Vehicle Pollutant Emission Standard is established to implement the "Environmental Protection Law of the People's Republic of China" and the "Air Pollution Prevention and Control Law of the People's Republic of China," aiming to prevent pollution from the exhaust of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health.

How Long Does It Generally Take to Charge a Dead Car Battery?

A dead car battery generally takes 1-2 hours to charge while the vehicle is in motion, but if charging while the vehicle is stationary, it may take around 20 hours. Below are some relevant tips for maintaining your car battery: 1. Turn Off Devices When the Engine Is Off: After parking, always turn off the vehicle's related devices to avoid battery drain caused by forgetting to turn them off. 2. Regularly Inspect the Battery: Under normal circumstances, during maintenance, the 4S shop will check the battery's charging capacity. However, if the battery frequently runs out of power, it is necessary to inspect it regularly. 3. Keep the Battery Clean: Keep the battery surface as clean and dust-free as possible. Owners can use a dry towel to wipe the battery surface frequently to prevent the formation of acidic corrosion powder, which could affect the battery's charging capacity.

How to Judge the Distance Between Cars

Car distance can be judged through the wiper and rearview mirror. Here are specific methods for different distances: 1. Judging the left car distance: The left car distance can be referenced by the protruding point of the left wiper. If this point coincides with the ground marking line or an object, it indicates the position where the wheel is about to travel. The lower left edge of the windshield can also be used for judgment. If it coincides with the marking line or an object, the distance between the vehicle and this position is about 60 centimeters. 2. Judging the right car distance: When the node of the right wiper coincides with the roadside, the distance is about ten centimeters. 3. Judging the front car distance: When viewing the front car from inside the vehicle, if you can just see the lower edge of the front car's bumper, the distance is about one meter. If only the upper edge of the front car's bumper can be seen from the lower edge of the windshield, the distance to the front car is only 0.5 meters.

What is the ABS Anti-lock Braking System and What Does It Do?

ABS stands for Anti-lock Braking System. The functions of ABS: Maximize the effectiveness of the brakes, reducing braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring excellent driving stability. Allow steering during emergency braking, providing good steering control. Avoid severe friction between tires and the ground, reducing tire wear. How ABS works: During braking, ABS quickly determines the wheel lock-up state based on speed signals from each wheel speed sensor, closing the normally open input solenoid valve on the wheel that is starting to lock, keeping the braking force constant. If the wheel continues to lock, the normally closed output solenoid valve opens, causing the braking pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir, preventing the wheel from fully locking due to excessive braking force. This keeps the braking state at the optimal point (with a slip rate S of 20%), achieving the best braking effect and the highest level of driving safety.

Can You Wash Inside the Hood When Cleaning Your Car?

You can wash inside the hood when cleaning your car, but it is not recommended to do it yourself. It is advisable to have it done by professionals at a 4S shop. When the engine operates at high temperatures, accumulated dirt and debris can produce unpleasant odors. Improper handling may lead to engine failure or electrical short circuits. Cleaning the engine compartment requires careful control of the water gun's flow, spray speed, and water volume. Special attention must be paid to pipes and electronic devices that should not get wet, and waterproof measures should be taken. The engine compartment can be rinsed with water, but the angle of rinsing must be controlled—always rinse from the front of the condenser, not the side, to avoid bending the aluminum fins. Bent fins can affect engine cooling and even cause air conditioning system failures. Never let water come into contact with the spark plugs. If water vapor enters the spark plugs, the car may fail to start. If non-original spark plugs have been installed, there may inevitably be some gaps around them. It is not recommended to wash older vehicles with water. Over time, the protective wiring pipes in the engine compartment may deteriorate. If the parking environment is poor, small animals may chew through the wiring pipes, so it is better to avoid water rinsing and use an air gun for cleaning instead.
