What is the China 6 standard?

China 6 standard refers to the vehicle emission standards. Compared with the 'China 5' standard, 'China 6' will strictly control the emission limits of pollutants. Under the exclusion of working conditions and test influences, the carbon monoxide emissions of gasoline vehicles will be reduced by 50%, the emission limits of total hydrocarbons and non-methane hydrocarbons will be reduced by 50%, and the nitrogen oxide emission limits will be tightened by 42%. The implementation time of the China 6 emission standard is divided into two phases: 1. The first phase: From July 1, 2020, all sold and registered vehicles must meet the China 6A standard. 2. The second phase: From July 1, 2023, all sold and registered vehicles must meet the China 6B standard; some cities will implement the China 6 light-duty vehicle emission standard in advance.

How to Determine if a Car is Burning Oil?

Methods to determine if a car is burning oil are as follows: 1. Check the exhaust pipe during cold starts. In the early morning after starting the vehicle, you can step out and observe if there is any blue smoke coming from the exhaust pipe. If there is slight blue smoke, it indicates a possibility of oil burning. 2. Observe the exhaust during acceleration. While driving or idling, if you press the accelerator hard and notice a large amount of blue smoke from the exhaust pipe, it suggests that the engine is burning oil. 3. Monitor oil consumption. Regularly check the oil dipstick to assess oil consumption and determine if oil is being burned. If you notice that the oil is being consumed significantly faster than usual before the scheduled maintenance date, it is important to address the issue promptly.

Are Off-Road Vehicles SUVs?

Off-road vehicles are not SUVs. The main differences between off-road vehicles and SUVs are as follows: 1. Different body structures. (1) Off-road vehicles adopt a non-load-bearing body structure similar to trucks. (2) SUVs adopt the same load-bearing body structure as sedans. 2. Different suspension structures. (1) Off-road vehicles mostly use double-wishbone independent suspension. (2) SUVs mostly use MacPherson suspension systems. 3. Different four-wheel drive systems. (1) Off-road vehicles must have a four-wheel drive system, whether it's full-time four-wheel drive or part-time four-wheel drive. (2) SUVs are mainly used in urban or suburban environments and do not necessarily require four-wheel drive. In many SUV models on the market, some only offer four-wheel drive in high-end configurations, and some even do not have four-wheel drive across the entire series.

Is it okay to shift to neutral at a red light with an automatic transmission?

For automatic transmission vehicles waiting at a red light, the appropriate gear to shift into depends on the duration of the red light. The recommended shifting practices are as follows: 1. If the red light is less than 30 seconds, it is recommended that the driver simply keep their foot on the brake. 2. If the red light lasts between 30 seconds and 1 minute, the driver should shift to N (Neutral) gear + handbrake. 3. For red lights longer than one minute, it is recommended to directly shift to P (Park) gear + handbrake. Below are the meanings represented by the letters on an automatic transmission: 1. P stands for Park. 2. R stands for Reverse. 3. N stands for Neutral. 4. D stands for Drive. 5. S stands for Sport. 6. L stands for Low. 7. M stands for Manual.

How to Tell When Car Brake Pads Need Replacement

Here are several indicators to determine if your car's brake pads need replacement: 1. The dashboard has a brake pad wear limit warning light; when illuminated, it indicates the pads should be replaced. 2. The thickness of brake pads typically ranges between 1-1.5cm (varies by manufacturer). When worn down to less than 3mm, replacement is necessary. Most brake pads have wear limit indicators. 3. If the brake pedal travels deeper than usual (increased braking distance) or feels softer, the pads may be nearing the end of their life. Modern brakes are self-adjusting, so increased pedal travel naturally occurs as pads wear. 4. Reduced brake fluid level in the reservoir. As pads wear, the gap between disc and pad increases. After automatic adjustment, the caliper pistons extend outward, requiring additional brake fluid - thus reducing reservoir levels. 5. Squealing or metallic scraping sounds during braking suggest metal-to-metal contact between pad and disc, signaling immediate replacement is needed.
