What was the emission standard for trucks in 2014?

[VanAubrey]

Most trucks in 2014 complied with China IV emission standards, but this depends on specific circumstances. Methods to check a vehicle's emission standard: 1. Check the motor vehicle certificate: New vehicles come with a compliance certificate that clearly states the emission standard. 2. Review the vehicle documentation: The emission standard can be found in the vehicle information section of the accompanying documents. Introduction to China IV emission standard: The China IV standard upgraded the exhaust after-treatment system compared to China III, reducing pollutant emissions by 50-60%. Compared to China IV, the China V standard reduces nitrogen oxide emissions by 25% and introduces additional restrictions on non-methane hydrocarbons and particulate matter emissions to reduce air pollution and combat smog.
