How to Identify China 6 Emission Standard?

China 6 emission standard is denoted by the symbol Ⅵ. There are two methods to identify it: 1. Check the vehicle conformity certificate: The vehicle conformity certificate can only be viewed after taking delivery of the car. 2. Check environmental protection information: (1) First, locate the vehicle nameplate near the B-pillar on the co-driver's side, which records basic vehicle information. Note down two important pieces of information from the nameplate: the complete vehicle model number and the engine model number. Then search online by opening the 'Motor Vehicle Environmental Protection Information Disclosure Website' and input the engine model number to search, finding the corresponding complete vehicle model number. (2) Once the model numbers match, you can view detailed information, where the emission standard will be indicated in the information column.

What does the A button in a car mean?

The 'A' on a car stands for the auto-hold function of the vehicle. Vehicles equipped with an electronic parking brake usually come with the auto-hold function, which is not enabled by default and requires the driver to manually activate it. Once the auto-hold function is activated, it eliminates the need for frequent operation of the handbrake or electronic parking brake, and for automatic transmission models, it avoids the frequent switching between D to N and D to P. More details are as follows: 1. When the vehicle brakes during driving and comes to a complete stop, even if the brake pedal is released, the vehicle may not continue to move. It will only proceed forward when the accelerator pedal is pressed again. 2. The English name for auto-hold is AUTO-HOLD, and this button is typically located next to the electronic parking brake.

What material is the three-way catalytic converter made of?

The material of the three-way catalytic converter is aluminum oxide (Al2O3), and the outer shell is made of stainless steel. Its working principle is that when high-temperature automobile exhaust passes through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of three gases (CO, HC, and NOx), carrying out certain oxidation-reduction chemical reactions to convert them into harmless gases. The reasons that cause the three-way catalytic converter to fail include: 1. Prolonged idling; 2. Delayed ignition timing; 3. Overly rich air-fuel mixture; 4. Engine burning oil; 5. Failure of the oxygen sensor; 6. Overheating due to incomplete cooling; 7. Cutting off the switch while the vehicle is in motion.

What Should Novice Drivers Do When Driving in the Rain?

Novice drivers should pay attention to the following points when driving in the rain: 1. Avoid overtaking, drive slowly, and check the depth of water before driving through puddles. 2. Remove fog to improve visibility, increase distance when meeting other vehicles, and use lights wisely when driving at night in the rain. More details are as follows: 1. Avoid overtaking. The steering wheel becomes more sensitive in the rain, making it harder to control. Drivers should stay in their designated lanes and minimize lane changes. It's best not to overtake on narrow roads to avoid skidding. Follow the vehicle ahead and avoid showing off. 2. Drive slowly. Wet roads can affect braking performance, especially for vehicles without electric power steering systems. High speeds may increase braking distance, potentially leading to rear-end collisions if braking is delayed. Sudden braking can also cause the vehicle to veer off course, and turning without slowing down may result in skidding or drifting. 3. Check the depth of water before driving through puddles. Avoid swerving or accelerating quickly through puddles. If the water is deep, take a detour. If it's shallow, slow down to prevent splashing, which could flood the ignition system. If the depth is unclear, step out to inspect it to avoid damaging the vehicle. 4. Remove fog to improve visibility. Before driving in the rain, ensure the windshield wipers are functioning properly. Rain and dim lighting can impair visibility. Use headlights, fog lights, tail lights, and wipers. If fog forms, set the air vent to blow on the windshield. Avoid using natural air, as it may bring more moisture into the car, worsening the fog. 5. Increase distance when meeting other vehicles. Some drivers may swerve to avoid puddles, moving toward the center of the road. When encountering oncoming traffic, control speed with the throttle and choose a wider section of the road to pass. Increase lateral distance to prevent side collisions due to skidding. 6. Use lights wisely when driving at night in the rain. Rely mainly on low beams, supplemented by width lights and fog lights. Pay attention to road markings and use lights to distinguish between the road surface and water.

What brand of tires does the Ant use?

The Ant uses Goodyear brand tires. Automotive Tires: Automotive tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the vehicle suspension, they help mitigate the impacts experienced during driving, ensuring good ride comfort and smooth driving performance. They also ensure excellent adhesion between the wheels and the road surface, improving the vehicle's traction. Avoiding Tire Scrapes: When passing over uneven road surfaces such as potholes or speed bumps, it is advisable to slow down. Avoid speeding or overloading, and refrain from making sharp turns, rapid starts, emergency braking, or driving over curbs.
