What time period do National III vehicles refer to?
3 Answers
The National III standard was implemented starting from July 1, 2007, and the National IV standard was implemented on July 1, 2010, marking the end of the National III era. Vehicles produced between 2007 and 2010 all comply with the National III standard. Below is a related introduction to National III and National IV: 1. National III emission standard: Mainly refers to HC emission values below 0.2g/km, CO emission values below 2.3g/km, NOx emission values below 0.15g/km, with no PM requirement. 2. National IV emission standard: Mainly refers to HC emission values below 0.1g/km, CO emission values below 1.0g/km, NOx emission values below 0.08g/km, with no PM requirement.
I remember driving a China III vehicle for several years. These vehicles refer to those launched around 2007 in China, complying with the National Phase III emission standards. Specifically implemented from July 1, 2007, new light-duty vehicles had to meet the China III emission standards, reducing pollutants like carbon monoxide and hydrocarbons. I used to own a 2008 model, which was China III, with stable performance but higher pollution compared to modern vehicles. Now, many cities like Beijing and Shanghai restrict China III vehicles, affecting commuting. It's also troublesome during annual inspections, possibly requiring additional maintenance for the emission system. When buying a car, check the vehicle registration certificate; if it's labeled China III, it belongs to that period. I recommend switching to a China VI or new energy vehicle for better environmental performance and peace of mind.
When I was learning to drive, I came across the concept of China III vehicles, which generally refers to cars produced between 2007 and 2010 that met the emission standards of that era. The China III standard was implemented nationwide in July 2007, imposing stricter controls on nitrogen oxide emissions from vehicle exhaust compared to the previous China II standard. A friend of mine owns a 2009 car that falls under the China III category. Nowadays, it's essential to check the traffic restriction policies before driving such vehicles, or else you might face fines when entering urban areas. To identify these vehicles, you can look at the environmental label or the last few digits of the VIN. With the emission standards upgrading to China VI, older China III vehicles depreciate quickly, so it's advisable to avoid them when buying used cars. This knowledge has helped me in my daily car usage, allowing me to steer clear of unnecessary troubles.
