Beijing is currently implementing the China 6b standard. Below is a detailed introduction to the national emission standards: Purpose: The strict national emission standards are introduced to regulate automobile manufacturers. These stringent standards help phase out some older vehicles that fail to meet the emission requirements. Development of National Emission Standards: The China 6 standard implemented since 2019 is the China 6a standard, which served as a transitional standard from China 5 to China 6. The true China 6 standard is the China 6b standard. Comparison Between China 6a and 6b: The emission requirements of China 6b are nearly twice as strict as those of China 6a, and it also adopts a more rigorous Real Driving Emissions (RDE) test.

I'm an ordinary car owner in Beijing with five years of driving experience. The current China 6b emission standard in Beijing is quite beneficial for the environment. Compared to the old China 5 standard, China 6b is much stricter, significantly reducing pollutants in exhaust emissions, such as nitrogen oxides and particulate matter, leading to noticeable air quality improvements. I believe all new cars must comply with this standard to be eligible for license plates. When buying a used car, be cautious—older China 5 models might not be allowed in Beijing, so don’t skip checking the environmental label. The upside is that China 6-compliant cars respond faster and come with an OBD system that monitors emissions in real-time, alerting you to any issues for timely repairs. In the long run, stricter standards push automakers to develop new energy vehicles, making electric cars more popular. I recommend paying attention to a vehicle’s emission details and being a responsible driver.

What Are the Considerations Before Buying a Car?

Here are the considerations before buying a car: 1. Choose a price range: Cars are consumables, so it's essential to select a model within your financial means when choosing a car. Additionally, purchasing a car often involves paying purchase tax, vehicle and vessel tax, insurance, and license plate fees, so it's crucial to consider the total cost of the vehicle. 2. Do your homework: In today's era of big data, it's easy to find the information you need online. Therefore, before buying a car, make sure to do thorough research, including understanding the pros and cons of the model, fuel consumption, maintenance costs, and the manufacturer's suggested retail price (MSRP). You can also look for reviews to see what others think about the car before deciding whether to choose it. 3. Beware of discounts: Most people hope for significant discounts when buying a car. However, if you encounter offers that seem too good to be true or the purchase price is much lower than expected, be cautious of falling into traps set by unscrupulous dealers. 4. Negotiate the price: Almost all car prices have significant room for negotiation, so always remember to haggle when buying a car. It's important to note that if the price can't be lowered, try negotiating for other benefits, such as free accessories, gas cards, maintenance service cards, or gift packages.

What to Do When the Airbag Warning Light Turns Red?

The airbag warning light remains flashing or stays on continuously for 6-8 seconds after the vehicle starts, or flashes for 5 seconds and then stays on while the vehicle is in motion. These two scenarios indicate a possible malfunction in the airbag system. The airbag system generally consists of components such as sensors, a microprocessor, an electronic control unit, an airbag cover and support ring, the airbag itself, and the airbag module. The illumination of the airbag warning light may be due to a failure in one of these components. Below are the relevant explanations: 1. If the light remains on continuously, it indicates a fault, such as an airbag malfunction, a clock spring failure, a collision sensor malfunction, a loose airbag connector, or a circuit break. In such cases, it is necessary to use a diagnostic tool to read the fault code promptly, identify the fault point based on the code, and resolve the issue. 2. The airbag light may also illuminate due to a false fault: Since the airbag is controlled by circuits, there are many reasons that can trigger the airbag light, such as severe battery depletion, which may cause the airbag to send a signal indicating low voltage in a certain airbag, generating a fault code. In such cases, simply clearing the code will suffice.

What are the reasons why the Qashqai won't start?

There are several reasons why the Nissan Qashqai won't start: 1. Battery depletion: The characteristic symptom is that the starter begins to turn but lacks sufficient speed or power, and eventually only makes a clicking sound without turning. Low temperatures in winter or forgetting to turn off certain electrical devices can prevent the vehicle from starting, especially when used for long periods of short-distance, low-speed driving in winter, causing the battery voltage to drop below the rated value and preventing normal operation. 2. Fuel flow obstruction: The characteristic symptom is a lack of fuel pressure in the engine's fuel supply line. This often occurs on extremely cold mornings due to long-term contamination of the fuel line. At very low temperatures, water and debris can mix and block the fuel line, preventing startup. 3. Poor ignition system performance: In extremely cold weather, the low intake temperature can cause poor fuel atomization in the cylinders. Combined with insufficient ignition energy, this can lead to cylinder flooding, where excessive fuel accumulates in the cylinder, exceeding the ignition concentration limit and preventing the engine from starting. 4. Valve coking: In winter, especially after using unclean gasoline, the non-combustible gum deposits in the gasoline can accumulate near the intake and exhaust valves and the combustion chamber, making it difficult to start the engine on cold mornings or even preventing ignition altogether.

Is It Necessary to Clean Carbon Deposits in the Spark Plug Cylinder?

Spark plugs need to be cleaned of carbon deposits inside the cylinder. The spark plug is a key component in the ignition system of a car engine. Every gasoline engine is equipped with spark plugs, one per cylinder, and some high-speed gasoline engines even have two spark plugs per cylinder. The function of the spark plug is to introduce the high-voltage electricity generated by the ignition coil into the engine cylinder, creating a spark between the electrodes of the spark plug to ignite the air-fuel mixture. Cleaning with carburetor cleaner: Carburetor cleaner is a specialized cleaning agent designed for oil and carbon deposits, effectively removing oil, grease, and carbon buildup. Squeeze the carburetor cleaner into a container, soak the spark plug in it for half an hour, then gently scrub the spark plug head with a soft brush to remove the carbon deposits. However, special care must be taken when using carburetor cleaner to avoid contact with eyes and skin. If accidental contact occurs, rinse immediately with plenty of water. Cleaning with white vinegar: White vinegar is a common household item that is easy to obtain. The method of cleaning with white vinegar is similar to that of using carburetor cleaner—soak for half an hour and then scrub with a brush. While white vinegar can indeed help remove some carbon deposits, its use is not recommended. The acidic nature of white vinegar can corrode the spark plug, significantly reducing its lifespan.

How to Adjust the Driver's Seat?

Ensure that the height of your eye level is positioned slightly above the center of the vertical distance of the vehicle's front windshield. The seat can be adjusted in many angles. Of course, depending on the vehicle's configuration level, the number of adjustable angle switches may vary. The position of the steering wheel should be adjusted according to the position of the seat.
