What is the difference between China VI and China V vehicle emission standards?

The distinction between China V and China VI vehicle emission standards can be identified by the letter designation on the vehicle's rear: China V is represented by 'V', while China VI is represented by 'VI'. The differences between the two standards are as follows: Different emission standards: China VI standards are more than 30% stricter than China V. Excluding the influence of operating conditions and testing, gasoline vehicles under China VI must reduce carbon monoxide emissions by 50%, total hydrocarbons and non-methane hydrocarbons by 50%, and nitrogen oxide emissions by 42% compared to China V. Different implementation times: The China V standard was implemented nationwide on January 1, 2017, as the fifth stage of national motor vehicle emission standards. The China VI standard has been in effect since July 1, 2019. Different principles: Under China V, diesel and gasoline vehicles had different emission standards. However, China VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing authorities: The China V standard was issued by the Ministry of Environmental Protection, while the China VI standard was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter designations: China V is represented by 'V', while China VI is represented by 'VI'. Different monitoring requirements for plug-in hybrid electric vehicles (PHEVs): Compared to China V, China VI has enhanced monitoring requirements for PHEVs, including energy storage systems, thermal management systems, regenerative braking, drive motors, generators, and other regulatory aspects. China V emission limits are as follows: Gasoline vehicles must not emit more than 1,000 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbon emissions must not exceed 68 mg per kilometer. Nitrogen oxide emissions must not exceed 60 mg per kilometer. PM (particulate matter) emissions must not exceed 4.5 mg per kilometer. China VI has two sub-standards: China VIa and China VIb, with the following limits: China VIa emission limits: Gasoline vehicles must not emit more than 700 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbon emissions must not exceed 68 mg per kilometer. Nitrogen oxide emissions must not exceed 60 mg per kilometer. PM emissions must not exceed 4.5 mg per kilometer. China VIb emission limits: Gasoline vehicles must not emit more than 500 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbon emissions must not exceed 35 mg per kilometer. Nitrogen oxide emissions must not exceed 35 mg per kilometer. PM emissions must not exceed 3 mg per kilometer. Affected by the China VI emission policy, although China V vehicles are not currently restricted in normal use (no driving bans or plate restrictions), their resale value is significantly impacted. For truck owners, if they purchase a truck on loan for hauling goods, the vehicle's depreciation after paying off the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. From this perspective, China VI vehicles, which have a longer service life and more road privileges, offer greater advantages.

What does the yellow half-circle exclamation mark light on the car mean?

Dashboard indicator light with a yellow half-circle exclamation mark typically indicates low tire pressure. Door status indicator light: This light shows whether the doors are fully closed. It illuminates when a door is open or not properly closed, alerting the driver that a door is ajar, and turns off when the door is closed. Parking brake indicator light: This light turns on when the parking brake handle (i.e., handbrake) is engaged. It automatically turns off when the handbrake is released. In some car models, this light may also illuminate when the brake fluid level is low. Battery indicator light: This light displays the working status of the battery. It lights up when the ignition is turned on and turns off after the engine starts. If it does not light up or remains lit continuously, the generator and circuit should be checked immediately.

Why don't many cars come with heated mirrors?

Many cars don't come with heated mirrors because this feature is only frequently used during rainy days and is rarely needed otherwise, so it's not installed. Function of heated mirrors: Heated mirrors refer to the feature where, when driving in rain, snow, fog, or other adverse weather conditions, the mirrors can be heated via electric heating wires embedded behind the mirror surface to ensure clear visibility. How to use heated mirrors: In rainy or snowy weather, the driver simply needs to press the defrost button, and the mirrors will heat up (typically between 35 to 60 degrees Celsius), removing fog or frost buildup on the mirror surface. This not only provides convenience but also enhances driving safety.

What animal inspired the invention of off-road vehicles?

Off-road vehicles are bionically designed based on the running style of leopards. An off-road vehicle is a type of automobile specifically designed for off-road driving. Characteristics of off-road vehicles: The main features include four-wheel drive, higher ground clearance, tires with better traction, elevated exhaust pipes, greater horsepower, and robust bumpers. Off-road vehicles not only adapt to various road conditions in the wild but also give a rugged and bold impression. Many people in cities also enjoy driving off-road vehicles. The three brothers of off-road vehicles: The three brothers differ in their load-carrying capacities. The one with the highest load capacity is called a heavy-duty off-road vehicle, the one with the smallest load capacity is called a light off-road vehicle, and the one in between is called a medium-duty off-road vehicle. The purpose of all-wheel drive is to ensure that if one wheel gets stuck in mud and slips, the other wheels can still drive the vehicle out of trouble. This is a major difference between ordinary cars and off-road vehicles.

Is a tire pressure of 2.0 normal in winter? Do I need to add air?

A car with a tire pressure of 2.0 can drive normally, provided that the car is in an unloaded state. Below is relevant knowledge about car tires: The role of tires: Car tires are one of the important components of a vehicle. They directly contact the road surface and work together with the car's suspension to mitigate the impacts encountered during driving, ensuring good ride comfort and smooth driving. They also ensure good adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capability, and bear the weight of the car. The important role tires play in vehicles is increasingly being recognized. Classification of tires: Full-size spare tire: A full-size spare tire has the exact same specifications as the other four tires on the car and can replace any temporarily or permanently unusable tire. Compact spare tire: This type of spare tire has a slightly smaller diameter and width compared to the other four tires, so it can only be used as a temporary replacement and must be installed on non-driving wheels. Additionally, the maximum speed should not exceed 80 km/h.
