What is the emission standard for the 2011 Tiida?
2 Answers
The 2011 Tiida complies with the China IV emission standard, which is the fourth phase of the national standard for motor vehicle pollutant emissions. More relevant information is as follows: 1. 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 aims to control and reduce vehicle emissions below specified limits. 2. The Tiida is a compact car under the Nissan brand. The 2011 Tiida is equipped with a 1.6-liter naturally aspirated engine, model code HR16DE, with a maximum power of 93kW and a maximum torque of 154Nm. This engine is paired with either a 6-speed manual transmission or a CVT transmission.
I've researched the emissions of the 2011 Nissan Tiida, and it indeed meets the China IV emission standards. These standards were implemented around 2007 with the aim of reducing pollutant emissions. My analysis: The Tiida's engine for this model year was optimized for combustion efficiency, resulting in significantly lower emission values compared to older China III vehicles. Driving such China IV-compliant cars in urban areas is quite suitable, with high annual inspection pass rates. However, the downside is that some regions have driving restriction policies. When purchasing a used car, be sure to check the environmental compliance sticker to avoid disadvantages. In the long run, China IV vehicles have relatively low maintenance costs, with oil changes and air filter replacements being key to maintaining stable emission performance. With growing environmental awareness, I recommend everyone consider more energy-efficient models.
