What is the difference between National IV and National V vehicle emission standards?

Here are the specific differences between National IV and National V standards: 1. Sulfur content: The sulfur content limit for National IV standard gasoline is 10mg; while for National V standard gasoline it's 50mg. 2. Emission limits: National V has stricter control on nitrogen oxides compared to National IV, with National V setting the emission limit at 25%. The National IV emission standard is China's fourth-phase motor vehicle pollutant emission standard, with main vehicle pollutants being HC, NOx, CO, PM, etc. Compared to National IV, the National V standard can reduce nitrogen oxide emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles.

Why do car lights sometimes flicker?

Car lights sometimes flicker due to poor contact in the lights, wiring, or switches. You can directly visit a 4S shop for inspection and repair. If the entire vehicle is under warranty, the headlight assembly can be replaced for free, as the headlights share the same warranty as the whole vehicle. Car headlights, commonly known as "headlamps," are responsible for nighttime driving illumination and can be considered the eyes of the car. Precautions: 1. The "soul" of the headlight is the bulb. Its performance directly affects nighttime illumination and driving safety. Therefore, high-quality headlight bulbs should be used to ensure safety. 2. Low-quality headlights have the following hazards: (1) Low-quality bulbs have a short lifespan and cannot guarantee stable quality. (2) High-quality bulbs have good light distribution, high brightness, while low-quality bulbs lack sufficient brightness, poor focus, and short range. During overtaking, they can cause visual illusions for the driver, leading to accidents. (3) Low-quality headlights, due to poor sealing, are prone to water ingress during rain or car washing, causing fog inside the lamp. In severe cases, this can lead to short circuits and fires. Therefore, when modifying headlights or replacing them due to damage, never consider low-quality bulbs.

Can National V Emission Standard Cars Still Be Registered in Heze?

National V emission standard cars cannot be registered in Heze. Below are the specific details about National V models: 1. Identification: The National V emission standard is marked with a Roman numeral "V". 2. Emission Levels: Under the National V standard, the carbon monoxide emission limit for gasoline vehicles is 1,000 mg/km. Compared to the National IV standard, the sulfur content in National V gasoline is reduced by 80%. For vehicles of the same displacement, the sulfur dioxide emissions from five National V cars are equivalent to those from one National IV car. Compared to the National IV standard, the new National V standard reduces nitrogen oxide emissions by 25% for light-duty vehicles and by 43% for heavy-duty vehicles.

Why Does a Car Battery Run Out of Power?

Car batteries may suddenly run out of power due to depleted battery charge, insufficient electrolyte levels, internal battery failures, or damage. Typically, a car battery has a lifespan of around 3 to 4 years, which can vary depending on driving habits and road conditions. Temporary power loss caused by leaving headlights on or listening to music with the engine off can often be resolved by removing the battery for recharging. More details are provided below: 1. Wipe the exterior of the battery with a damp cloth to remove dust, grease, white powder, or other contaminants that may cause leakage from the terminals (positive and negative poles). Regular cleaning prevents the buildup of acidic corrosion powder on the terminals, extending the battery's lifespan. 2. Open the battery's water-filling caps and check whether the water level is within the normal range. Most batteries have upper and lower level markers for reference. If the water level is below the lower marker, add distilled water. In emergencies, filtered tap water can be used if distilled water is unavailable. Do not overfill—the water level should be between the upper and lower markers. 3. Check whether the battery is charging properly. Using a multimeter, measure the voltage across the battery terminals after starting the engine. A reading above 13V is considered normal. If the charging voltage is too low, have a professional inspect the charging system. Car batteries generally last 2 to 3 years. Beyond this period, drivers should pay extra attention to battery maintenance and replace it promptly if necessary to avoid potential hazards.

What is the model of a tractor driver's license?

Tractor driver's licenses are categorized into the following models: 1. Medium-sized tractors (with an engine power exceeding 14.7 kilowatts), the license code for permitted operation is "G". 2. Small steering wheel tractors (with an engine power below 14.7 kilowatts), the license code for permitted operation is "H". 3. Hand tractors, the license code for permitted operation is "K". Here are some additional details: Precautions for operating a tractor include: 1. Parking location: It is best to park in a garage, but avoid storing it with fertilizers or pesticides to prevent corrosion from volatile substances. If parking outdoors, choose a well-ventilated area on higher ground and cover it with plastic sheets or other protective materials to prevent mechanical damage and rust. 2. Supporting the chassis: Elevate the tractor using wooden blocks or bricks to reduce the load on the tires. If the chassis is not supported, the tires should be inflated 10%—20% more than usual, and regular checks and inflation are necessary to avoid underinflation.
