What is the equivalent of Euro III emission standard in China?
4 Answers
Automotive Euro III is equivalent to China's National III emission standard. Below is an introduction to the National III emission standard: 1. The National III standard is China's third-stage vehicle emission standard, which is equivalent to the Euro III emission standard in terms of tailpipe pollutant levels. The key difference is that new vehicles must be equipped with an OBD (On-Board Diagnostics) system. 2. The characteristic of the OBD system lies in the increased number of detection points and detection systems. Oxygen sensors are installed at both the inlet and outlet of the three-way catalytic converter, ensuring compliance through real-time monitoring of vehicle emissions, thereby better guaranteeing the implementation of the Euro III emission standard. 3. When vehicle emissions fail to meet the Euro III standard due to factors like fuel quality, implementing the National III standard will increase the cost per vehicle. To stably meet the National III emission standards, vehicles must be equipped with technical measures that ensure pollutant emissions meet the National III standard, along with using fuel that meets the Euro III standard. 4. There is not much difference between National III and Euro III standards; they are essentially equivalent with only minor adjustments in certain aspects. In China, segmented measurement of exhaust emissions is adopted, measuring under two conditions: 2540 and 5040, whereas abroad, instantaneous engine operating conditions are measured.
The Euro 3 emission standard basically corresponds to the China 3 standard, both being products of the same era. I remember when China was implementing the China 3 standard, many automakers simply adapted Euro 3 technology to meet the requirements. However, these older vehicles are causing headaches now. For example, China 3 diesel vehicles started being restricted in many cities last year, with some areas even imposing strict limitations on ownership transfers. By the way, for those buying new cars now, it's crucial to aim for the China 6B standard, as the emission requirements are over ten times stricter than back then. Owners of older vehicles should pay close attention to local policy changes.
Euro 3 is roughly equivalent to China's National 3 standard, but with some localized requirements added domestically. When Europe implemented Euro 3 in 1999, China didn't adopt National 3 until 2007, creating a technological generation gap. Currently, the easiest way to check your vehicle's emission standard is to look at the registration date on the green vehicle license. Gasoline cars registered between 2007-2010 are most likely National 3. My neighbor's old Bora got restricted last year due to emissions and had to reluctantly replace it with a new car.
Simply put, Euro 3 is equivalent to China 3, though the national standard is actually stricter. Interestingly, automakers employed various tricks to meet the standards back then, such as installing secondary air pumps. Nowadays, China 3 vehicles are indeed struggling, with restrictions even within Beijing's Fifth Ring Road. To check your vehicle's status, look for 'China III' marked on the duplicate of your vehicle license, or distinguish by the number of stars on the environmental label.
