When was China IV emission standard implemented?

Vehicles produced after 2011 comply with China IV emission standards. The China IV standard was implemented nationwide on July 1, 2010. Compared with China III, the China IV standard features upgraded exhaust after-treatment systems, reducing pollutant emissions by 50% to 60% compared to China III. Below are relevant details: 1. Emission standards: As global environmental pollution becomes increasingly severe, countries worldwide are implementing stricter emission standards, which significantly benefits environmental protection. 2. Exhaust treatment: Under stringent emission standards, automakers actively develop new technologies to reduce engine exhaust emissions.

Can You Drive on the Highway Without ETC?

You can drive on the highway without an ETC. ETC is not mandatory. Since January 1, 2020, vehicles without ETC will no longer enjoy various toll reduction policies and must pay tolls manually at the toll booth. It might be inconvenient during holidays. ETC is just a different payment method and does not affect whether you can drive on the highway. There are two toll payment methods on highways: manual payment and ETC payment. ETC stands for Electronic Toll Collection. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID and vehicle registration certificate. If someone else is applying on behalf of the owner, they must also bring their valid ID. The photocopy of the vehicle registration certificate must include the page with the most recent annual inspection stamp. Additionally, you need a bank card for deducting highway tolls, and the applicant must be between 18 and 60 years old and the registered owner of the vehicle. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at the toll booth. The computer network technology then processes the payment with the bank in the background, allowing the vehicle to pass through the highway or bridge toll booth without stopping to pay. Benefits of installing ETC: Save time: Avoid waiting in queues; Green and eco-friendly: Reduces noise and exhaust emissions as vehicles pass through toll booths without stopping; Reduce wear and tear: Saves costs by decreasing the frequency of vehicle starts and stops, reducing wear and fuel consumption. Users also enjoy toll discounts; Improve efficiency: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC more advanced, faster, and high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

Can You Make a U-Turn on a Single Yellow Line?

If it is a single yellow dashed line, you can make a U-turn when it does not affect the normal flow of traffic. However, if it is a single yellow solid line, making a U-turn is not allowed and is considered a traffic violation. According to the "Road Traffic Safety Law," violators will be fined 200 yuan and receive 3 penalty points. Generally, on long roads, there are usually white solid lines, dashed lines, or yellow solid or dashed lines in the middle section or before intersections. As long as it is a solid line, U-turns are prohibited. Permissible U-turn situations: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, you can make a U-turn. If there is a U-turn traffic light, you must follow its instructions. If there is no traffic light, you should assess the situation and make a U-turn only if it does not obstruct other vehicles or pedestrians. Intersections without explicit no-U-turn or no-left-turn signs: If there is no explicit prohibition against U-turns, you can make a U-turn. "No explicit prohibition" means the absence of "No U-turn" or "No Left Turn" signs, and the centerline is not solid. In such cases, you can safely make a U-turn. Yellow grid lines also allow U-turns: Yellow grid lines are actually no-parking zones marked at intersections prone to congestion due to temporary stops, important facility entrances, or other designated areas. Any vehicle stopping on these grid lines (including waiting for traffic signals) is considered a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed as long as there is no central barrier. The presence of yellow grid lines without barriers is equivalent to "U-turn permitted." Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, you must wait for the green light to make a U-turn. When no-left-turn and U-turn-permitted signs coexist: U-turns are allowed, but left turns are prohibited. However, "No U-turn" does not necessarily mean "No Left Turn." Precautions when making a U-turn at an intersection: Observe road markings—if it is a solid line, U-turns are prohibited under any circumstances. Continue driving until you find a suitable location for a U-turn. If there is a "No Left Turn" sign ahead, even if there is no mention of a U-turn prohibition, you cannot make a U-turn at that intersection because U-turns and left turns are closely related—a U-turn always involves a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, you cannot make a U-turn at that intersection. Always yield to through traffic when making a U-turn. Only proceed if it does not interfere with the normal flow of vehicles, or you will bear full responsibility for any accidents. Near the intersection stop line, lanes often have guiding arrows for drivers to choose their direction. The leftmost lane does not always have a left-turn arrow—if there is a straight arrow, even without explicit no-U-turn signs, U-turns are not allowed. U-turns on pedestrian crosswalks are also prohibited and considered violations.

How to Distinguish Between National V and National VI Standards for Sedans?

The National V emission standard is marked with the Roman numeral "V", while the National VI emission standard is marked with "Ⅵ". When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes details such as the model, color, emission standard, engine number, and chassis number. For used cars, you can check whether it meets National V or National VI standards by searching the vehicle's complete model number on the environmental protection website. Here are several methods to determine whether a car meets National V or National VI standards: 1. Check the vehicle's environmental label: The simplest and most direct method is to look at the vehicle's environmental label, which clearly indicates the standard on the back. 2. Query on the Motor Vehicle Management Center website: Visit the Motor Vehicle Exhaust Pollution Supervision and Management Center website to check. 3. Visit the Vehicle Management Office: Bring the vehicle registration certificate (either the original or a copy) to the Vehicle Management Office for inquiry. 4. Check the vehicle's factory certificate: For new cars, you can refer to the vehicle's factory certificate, but generally, this document is kept at the Vehicle Management Office. Therefore, when buying a new car, it is advisable to make a copy for your records. 5. Roughly distinguish based on the vehicle's registration year: Make an approximate distinction based on the year the vehicle was registered.

What type of engine oil is suitable for a 1.5T engine?

Fully synthetic engine oil is suitable, generally requiring replacement every 8,000-10,000 kilometers or every six months to a year. If the vehicle is used infrequently, the oil may oxidize and degrade over time, necessitating replacement within a year. Semi-synthetic engine oil should be replaced every 6,000-8,000 kilometers or approximately every seven months. Mineral oil requires replacement every 5,000 kilometers or every six months. Precautions for changing engine oil: 1. Do not overfill: When changing the oil, always pay attention to the oil level mark. If there is too much oil, the excess can easily overflow into the combustion chamber, leading to carbon buildup over time and, in severe cases, may cause oil burning. 2. Do not underfill: If the oil level is below the minimum mark, it can result in low oil pressure, reducing the lubrication effectiveness. In such cases, simply top up with the same type of oil.
