What are the national vehicle emission standards in China?

China's vehicle emission standards: To date, they have been implemented in six main stages, namely National I, National II, National III, National IV, National V, and National VI. The purpose of vehicle emission standards is to enforce environmental protection laws, reduce and prevent pollution from vehicle exhaust, protect the ecological environment, and ensure human health. Below is a detailed introduction to China's vehicle emission standards: 1. National I Emission Standard: In the early 1980s, China issued a series of emission standards for vehicle exhaust pollution control, including the "Idle Emission Standard for Gasoline Vehicles," "Free Acceleration Smoke Emission Standard for Diesel Vehicles," "Full Load Smoke Emission Standard for Automotive Diesel Engines," and their measurement standards. From then on, China's vehicle emission standards began to be established step by step. It was not until July 1, 2001, that the National I standard was fully implemented nationwide. 2. National II Emission Standard: By this stage, China had developed a relatively complete system of vehicle exhaust emission standards and testing. Beijing was the first to implement the National II emission standard. The requirements for various pollutant emission standards were further increased under the National II standard, which was implemented nationwide by July 1, 2004. 3. National III Emission Standard: On December 30, 2005, Beijing began implementing the National III emission standard, and it was during this time that OBD devices started to be widely used. The specific implementation times were: light-duty diesel vehicles on July 1, 2009; heavy-duty gasoline vehicles on July 1, 2010; heavy-duty gas vehicles on July 1, 2008; and heavy-duty diesel vehicles on July 1, 2008. 4. National IV Emission Standard: National IV fuel was introduced in Beijing on New Year's Day 2008, followed by cities like Beijing, Shanghai, and Guangzhou implementing the National IV standard. The nationwide implementation times were: light-duty diesel vehicles on July 1, 2013; heavy-duty gasoline vehicles on July 1, 2013; heavy-duty gas vehicles on January 1, 2011; and heavy-duty diesel vehicles on July 1, 2013. 5. National V Emission Standard: The National V emission standard was fully implemented nationwide starting July 1, 2017. Compared to the National IV standard, it reduced nitrogen oxide emissions by 25% and introduced stricter PM emission limits. 6. National VI Emission Standard: The "National VI" standard is an upgrade of the National V standard. Compared to "National V," "National VI" will strictly control pollutant emission limits, making it one of the most stringent standards globally. In practice, "National VI" reduces carbon monoxide emissions from gasoline vehicles by 50%, total hydrocarbon and non-methane hydrocarbon emission limits by 50%, and nitrogen oxide emission limits by 42%.

Does a Car Need Carbon Deposit Cleaning?

Does a Car Need Carbon Deposit Cleaning? Cars require regular carbon deposit cleaning. Here are the relevant details: Regular Cleaning: It depends on the situation. For cars driven in urban areas, cleaning is recommended every 20,000-30,000 kilometers, while for those driven on highways, every 30,000-40,000 kilometers. According to the Maintenance Manual: Owners can refer to their vehicle's maintenance manual and the recommended spark plug replacement interval to check for carbon deposits and perform necessary cleaning. Generally, maintenance manuals suggest replacing spark plugs every 20,000-30,000 kilometers, making it appropriate to clean the engine's carbon deposits during this interval. Specialized Equipment Cleaning: This involves using specialized equipment to clean carbon deposits from areas prone to buildup, such as the intake tract, valves, and fuel system, without disassembling the engine.
