National IV standards were implemented nationwide on July 1, 2010. Below is more information about National IV standards: 1. Introduction: (1) National IV emission standards represent the fourth stage of China's motor vehicle pollutant emission standards. (2) National IV emission standards refer to the regulations requiring motor vehicles to control and reduce emissions below specified limits through technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices. 2. Requirements: National IV standards mandate approximately 50% lower emissions for various pollutants compared to National III. 3. Implementation timeline: (1) Conventional motor vehicles adopted National IV standards on July 1, 2010. (2) Diesel vehicles over 3.5 tons implemented National IV standards in 2012. (3) Diesel vehicles under 3.5 tons adopted National IV standards in 2013.
I remember that the China IV emission standard for motorcycles was mandatorily implemented from July 1, 2019. Since then, newly produced motorcycles must meet this stricter emission requirement, mainly to reduce pollution and make the air cleaner. As someone who frequently repairs vehicles, I've seen many older bikes develop issues due to high emissions, such as engine carbon buildup or excessive exhaust emissions. China IV motorcycles use more advanced catalytic converters, reducing harmful gas emissions. For owners looking to buy used motorcycles, I recommend checking the production date—those manufactured after July 2019 are China IV versions, otherwise they might still be China III standard and fail the annual inspection. Upgrading early not only benefits the environment but also saves money on repairs. Remember, don't be tempted by cheap older models—they affect both performance and urban air quality.
The China IV emission standard for motorcycles was officially implemented on July 1, 2019, marking a significant environmental milestone. I find this timing particularly crucial as it signifies the motorcycle industry's increased focus on sustainable development. Compared to the old standard, China IV-compliant vehicles emit significantly less carbon monoxide and nitrogen oxides, making a substantial contribution to alleviating urban smog. When driving, I always pay attention to these details because every small change can lead to a healthier life. If you're planning to buy a new motorcycle, remember to choose models from 2019 or later, as they typically feature improved fuel systems and exhaust treatment, making them quieter and more eco-friendly. Overall, the policy push was timely, helping us protect the environment for future generations.
