Why Do Diesel Vehicles Need Urea Solution?

Diesel vehicles add urea solution to reduce exhaust emissions and protect the atmospheric environment. The use of urea in vehicles is to convert harmful nitrogen oxides in the exhaust into nitrogen and water. The exhaust emitted by engines is extremely harmful to the atmospheric environment. With increasingly stringent environmental regulations, exhaust treatment systems have been developed to ensure compliance. The primary harmful substances in diesel exhaust are nitrogen oxides and particulates. The exhaust treatment system can reduce particulate emissions. Once urea is used in the vehicle, as long as the engine is running, the urea is injected into the exhaust treatment system, where it decomposes into ammonia gas at high temperatures.

What are the differences between China 5 and China 6 vehicle models?

The differences between China 5 and China 6 emission standards are as follows: Different emission standards: The China 6 emission standard is more than 30% stricter than China 5. Excluding the influence of driving conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: The China 5 standard was implemented nationwide on January 1, 2017. The China 6 standard was implemented on July 1, 2019. Different principles: During the China 5 phase, diesel and gasoline vehicles had different emission standards, but China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing departments: The China 5 standard was issued by the Ministry of Environmental Protection. The China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: China 5 is represented by 'V,' and China 6 is represented by 'VI.' Different monitoring requirements for plug-in hybrid electric vehicles: Compared to China 5, China 6 has improved monitoring requirements for plug-in hybrid electric vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. China 5 standard limits are as follows: Gasoline vehicles must not emit more than 1,000 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 mg of PM fine particles per kilometer driven. China 6 has two standards: China 6a and China 6b, as follows: China 6a standard limits: Gasoline vehicles must not emit more than 700 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 mg of PM fine particles per kilometer driven. China 6b standard limits: Gasoline vehicles must not emit more than 500 mg of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 mg of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 mg of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 mg of PM fine particles per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles are not currently restricted in normal use, their resale value will be significantly impacted. For truck owners who purchase vehicles on loan for freight transport, after repaying the loan, the vehicle's depreciation equals the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China 6 vehicles, with longer service life and more road rights, have greater advantages.

How to Play Back Videos on a Car Dash Cam?

Methods to play back videos on a car dash cam: 1. Remove the TF memory card from the dash cam and insert it into a card reader. Connect it to a computer to read the contents like a USB drive, then locate the video files; 2. Connect the dash cam to a computer using a USB cable. The computer will recognize the dash cam as a mass storage device. Sometimes, the dash cam screen may prompt you to select the storage device. Once opened, you can access the contents; 3. Many dash cams come with a built-in screen, allowing playback directly on the device. The method is to first pause the recording, then press the MODE key to navigate to the recorded videos, and click OK to play.

Can a leaking shock absorber be repaired?

Whether a leaking shock absorber can be repaired depends on the specific situation. If the leakage is caused by normal aging and damage of the internal oil seal, it can be repaired. However, if the leakage is induced by factors such as strong impact, it cannot be repaired and must be replaced. This is currently the mainstream repair method adopted by 4S shops and repair shops. To rapidly attenuate the vibration of the frame and body and improve the smoothness and comfort of the car, shock absorbers are generally installed on the vehicle's suspension system. The most widely used type in automobiles is the double-acting telescopic shock absorber. Shock absorbers are vulnerable components during vehicle use, and their condition directly affects the driving stability of the car and the lifespan of other components.

On what road surfaces are vehicles prone to wheel lock-up?

Vehicles are prone to wheel lock-up when braking on road surfaces with low friction coefficients, such as icy or snowy roads. Due to the minimal friction generated on such surfaces, when the friction between the brake pads and brake discs exceeds that between the road and the wheels, the wheels may lock up and skid, significantly increasing the risk of rollover or tipping accidents. Wheel lock-up is defined as the tires ceasing to rotate while the vehicle continues to move, creating dynamic friction between the tires and the road surface. A similar phenomenon is wheel spin during acceleration (where the vehicle remains stationary while the tires rotate freely). In certain high-performance models, switching the driving mode to drift mode can deactivate the wheel lock-up system. The anti-lock braking system (ABS) is a crucial safety feature designed to prevent such accidents.
