Since the implementation of the China VI standard on January 1, 2019, China V vehicles have been ineligible for licensing in Shenzhen. 2. Many cities and regions across the country have gradually begun implementing the China VI standard, leading to price drops for China III, China IV, and China V vehicles. 3. China VI A standard: Carbon monoxide emissions must not exceed 700 milligrams per kilometer. Non-methane hydrocarbon emissions must not exceed 68 milligrams per kilometer. Nitrogen oxide emissions must not exceed 60 milligrams per kilometer. PM fine particulate emissions must not exceed 4.5 milligrams per kilometer.

When Should the Rear Axle Oil Be Changed?

According to different oil brands, the replacement intervals vary. Below are the relevant details: 1. Generally, for most oil brands, the rear axle gear oil should be replaced every 20,000-30,000 kilometers or approximately every six months. Recommended brands include Shell or Great Wall. 2. Additionally, the replacement interval depends on the vehicle's load conditions. Typically, imported cars require replacement every 40,000 kilometers, domestic mid-sized cars every 20,000 kilometers, and micro cars every 10,000 kilometers. 3. Gear oil primarily refers to the lubricant used in transmissions and rear axles. It differs from engine oil in terms of usage conditions, composition, and performance. Gear oil mainly functions to lubricate gears and bearings, prevent wear and corrosion, and assist in heat dissipation for the gears.

What Type of Engine Oil is Best for Cars in Summer?

Car engine oils for summer use are graded as: 20, 30, 40, 50. The higher the number, the greater the viscosity, and the higher the maximum applicable temperature. Below are the relevant details: 1. The number following the SAE oil grade indicates the lowest suitable temperature. 5w-30 degrees, 10w-25 degrees, 15w-20 degrees. Therefore, by checking the grade of oil you are using and comparing it with the local winter's lowest temperature, you can determine if your oil is suitable. 2. The oil grade for summer use is SAE10W-40, meaning that if the lowest temperature does not drop below minus 25 degrees, there is no need to switch to an oil with better low-temperature resistance in winter. For summer, it's advisable to choose an oil with higher viscosity, and 10W-40 oil is very suitable for summer use.

What are the symptoms of a bad car air conditioning pump?

If the air conditioning pump is faulty, the most obvious symptom is the inability of the air conditioning system to cool. Below are the relevant details: 1. There are many reasons for abnormal noises from the air conditioning pump, such as damage to the compressor electromagnetic clutch, severe internal wear of the compressor, etc. The electromagnetic clutch is a common source of abnormal noises due to its location, making it prone to exposure to rain and dirt. When the bearings inside the electromagnetic clutch are damaged, abnormal noises occur. Additionally, a compressor drive belt that is too loose or too tight, lack of lubricating oil, or repeated engagement of the electromagnetic clutch can all cause abnormal noises. 2. Leakage in the air conditioning pump is also a common issue, with the specific leakage location being the junction between the compressor and the high and low-pressure pipes. When refrigerant leaks, compressor lubricating oil is also lost, leading to poor compression by the air conditioning pump or the air conditioning system not working. 3. Moreover, there are many reasons why the air conditioning system may not work, most of which are related to electrical circuits. A preliminary check can be done by directly supplying power to the compressor electromagnetic clutch to determine if it is faulty.

What do the letters in tire speed ratings represent?

Letters from A to Z represent the certified speed ratings of tires, ranging from 4.8 km/h to 300 km/h. Here are the relevant details: 1. Generally speaking, the further the letter representing the tire speed rating is in the alphabet, the better the tire's performance, and the higher its price. 2. Tires with different speed ratings have different applicable ranges. P—T grade tires (maximum speed 150—190 km/h) are suitable for small and compact cars, U—V grade tires (maximum speed 200—240 km/h) are suitable for mid-to-high-end cars, while the highest-performing W—Z tires, which can withstand speeds between 240—300 km/h, are typically used in large luxury cars and supercars.

What to Do When a New Energy Vehicle Fails to Charge?

New energy vehicle chargers failing to charge can be attributed to the following reasons: 1. Blown fuse in the battery section. 2. Poor contact; 3. Poor contact in the battery plug; 4. Battery lifespan expiration. Solutions: (1) Replace the fuse in the battery section; (2) Try reconnecting or replacing the wiring. If the issue persists, visit a 4S store for repairs. (3) Replace the battery. New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources, integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and novel structures.
