It is better to buy a China 6 vehicle. The difference between China 6 and China 5 lies in the stricter requirements for various vehicle emissions, necessitating comprehensive hardware upgrades. Starting from July 1, 2020, the China 6 emission standard for light-duty vehicles was implemented nationwide, prohibiting the production of China 5 emission standard vehicles. Therefore, it is advisable to choose China 6 vehicles whenever possible. The following are details about China 5 and China 6 standards: 1. The China 6 standard imposes approximately 40% to 50% stricter limit requirements compared to China 5. 2. Compared to China 5, the China 6 standard reduces nitrogen oxides by 77%, particulate matter by 67%, introduces a limit requirement for particle number (PN), and tightens the durability requirements for emission control devices and the related requirements for onboard diagnostic systems (OBD). 3. The China 6 standard introduces more stringent compliance supervision requirements, including type inspection and information disclosure, production consistency inspection, new vehicle inspection, in-use vehicle compliance inspection, etc., and simplifies the compliance determination method.

Why does the wiper make a squeaking noise when wiping the glass?

Reasons for the wiper making a squeaking noise when wiping the glass: 1. Wiper's own issue: Wipers are rubber products, and prolonged use can cause aging and hardening. If the wiper hasn't been in contact with water for a long time, it becomes dry, leading to friction problems during operation. 2. There is a foreign object between the wiper and the glass. Stop the wiper in the middle position, then gently lift and twist it downward a few times. After resetting, check if the noise is eliminated. If the wiper makes noise both during the upward and downward strokes, the wiper blade needs to be replaced. Wipers, also known as windscreen wipers, are devices used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety.

What does it mean when the skid warning light turns yellow on the car?

The skid warning light turning yellow on the car may be due to slippery road conditions causing the ABS to activate, which triggers the light. If the skid warning light stays on for a long time, it could indicate a fault with the ABS pump, an error in signal transmission, or a false alarm from the computer. In such cases, prompt repairs are necessary. If the light turns on briefly and then goes off on its own, the first scenario is more likely. A yellow warning light on the car could indicate: 1. Engine fault light, signaling an issue with the engine; 2. Power steering fault light; 3. Engine power control system; 4. Bulb failure indicator; 5. Low washer fluid level warning light; 6. Anti-lock braking system (ABS) light.

How Often Should Fuel Cleaner Be Added?

Fuel cleaner is generally added every 5,000 to 10,000 kilometers. The main function of fuel cleaner is to remove carbon deposits. New vehicles do not require fuel cleaner; it is only necessary when the vehicle has reached a certain mileage and there is a certain amount of carbon buildup in the engine and fuel system. Below is an extended introduction: 1. Introduction to Fuel Cleaner: Fuel cleaner is currently the most frequently used type of fuel additive on the market. It mixes with fuel for combustion and, through its surface activity, helps decompose and break down deposits, dissolving carbon buildup to achieve a cleaning effect. 2. Function of Fuel Cleaner: The primary role of fuel cleaner is to remove carbon deposits, which mainly form due to fuel quality and driving habits. Fuel itself is the best substance for cleaning carbon deposits.

What is the reason for the clutch not rebounding and needing to be hooked with the foot to work properly?

According to the vehicle conditions, this type of fault is mostly caused by excessive sludge in the clutch release bearing bushing, poor return, or a broken clutch pedal. The repair method for this situation is to disassemble and clean the transmission. Reasons for the clutch not rebounding: Air mixed into the clutch pipeline system; Clutch fluid is too dirty with impurities, causing severe internal wear of the clutch master cylinder or blockage of the return oil hole; Insufficient or broken clutch return spring tension; Excessive wear gap in the clutch linkage push rod. Precautions for clutch use: The clutch must be cleaned thoroughly before installation to remove anti-rust grease and debris; The clutch can be installed coaxially or on separate shafts, but axial fixation is mandatory; When the wet electromagnetic clutch is working, lubricating oil must be added between the friction plates; The power supply and control circuit, the clutch power supply is DC 24 volts; When installing the jaw-type electromagnetic clutch, a certain gap must be ensured between the end face teeth to prevent gear grinding during idling.

How are A, B, and C class vehicles classified?

According to the classification standards for vehicles: Class A (including A0/A00) refers to compact cars, Class B refers to mid-size cars, and Class C refers to premium cars. The classification is mainly based on parameters such as wheelbase, engine displacement, and weight. The further the letter sequence, the longer the wheelbase, the larger the displacement and weight, and the higher the luxury level of the car. A-class cars are divided into three categories. Among them, A00 can also be called micro cars. The wheelbase of A00-class cars should be between 2 meters and 2.2 meters, with an engine displacement of less than 1 liter. For example, the Alto belongs to the A00-class car. The wheelbase of A0-class cars is between 2.2 meters and 2.3 meters, with a displacement of 1 to 1.3 liters, typically represented by the hatchback Xiali. Generally, the wheelbase of A-class cars ranges from about 2.3 meters to 2.45 meters, with a displacement of about 1.3 to 1.6 liters. The Jetta from FAW-Volkswagen and the POLO from SAIC Volkswagen are considered classic models in the A-class category. B-class mid-size cars have a wheelbase of about 2.45 meters to 2.6 meters, with a displacement ranging from 1.6 liters to 2.4 liters. Models such as the Audi A4, Passat, Zhonghua, and Eastar all belong to the B-class category. C-class premium cars have a wheelbase of about 2.6 meters to 2.8 meters, with an engine displacement of 2.3 to 3.0 liters. The main C-class car is the Audi A6. D-class classification: D-class luxury cars are mostly large in size, with spacious interiors and powerful engines. Their wheelbase is generally more than 2.8 meters, and the displacement is mostly above 3.0 liters. Common D-class cars include the Mercedes-Benz S-Class, BMW 7 Series, Audi A8, Rolls-Royce, and Bentley.
