What is the emission standard for the 2011 Nissan Tiida?
2 Answers
The 2011 Nissan Tiida complies with the China IV emission standard. The China IV emission standard is the fourth phase of the national standard for motor vehicle pollutant emissions. The main pollutants emitted by vehicles include HC, NOx, CO, PM, etc. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard controls and reduces vehicle emissions to below specified levels. Relevant information about the China IV standard is as follows: 1. The China III and China IV standards are based on the Euro 3 and Euro 4 vehicle emission standards. Compared to China II, China III further reduces the limits for pollutant emissions. The exhaust pollutant emission limits under China III are 30% lower than those under China II, while China IV will further reduce them by 60%. 2. According to the plan, Beijing implemented the 'National Fourth Phase Motor Vehicle Pollutant Emission Standard' (hereinafter referred to as the 'China IV emission standard') for all newly added motor vehicles in 2013. Gasoline meeting the China IV standard began to be supplied citywide starting from January 1, 2008.
Let's talk about the 2011 Nissan Tiida. Its emission standard was mainly China IV, as China IV had just come into effect around that time, and many new cars were manufactured to meet this requirement. Specifically, the emission calibration involved stricter limits on particulate matter and nitrogen oxides compared to the older China III standard, which helped reduce air pollution. However, after purchasing the car, it's best to check the Vehicle Conformity Certificate or the environmental label to confirm, as some early batches might have mixed China III products, especially for Tiidas bought in the first half of 2011. Nowadays, China IV vehicles might face restrictions in cities with traffic control policies like Beijing. It's recommended that owners regularly maintain the exhaust system to keep emissions compliant. The car is also fuel-efficient and drives smoothly overall, so not upgrading isn't a big issue, but in the long run, it's still worth considering switching to a more environmentally friendly model.
