When did the China III emission standard come into effect?
4 Answers
The China III emission standard was implemented on July 1, 2008. Here are detailed introductions about the China III standard: 1. Overview: The China III standard is the abbreviation for the National Phase III Emission Standard, equivalent to the Euro III emission standard. This means the tailpipe pollutant levels under China III are comparable to Euro III. However, China III mandates that new vehicles must be equipped with an OBD (On-Board Diagnostics) system. 2. China III Engines: China III engines improved upon China II engines by modifying internal structures, typically involving components such as cylinder heads, intake and exhaust manifolds, valves, camshafts, pistons, and corresponding auxiliary mechanisms. These modifications aim to reduce emissions without compromising power, requiring higher precision for each component, though external differences are not significant.
I remember the China III emission standards were officially implemented on July 1, 2007. Back then, I drove my old car to trade in for a new one, and all new vehicles had to comply with this regulation. China III represents the national third-phase vehicle emission requirements, primarily aimed at reducing tailpipe pollutants such as carbon monoxide and nitrogen oxides. The car market underwent significant changes at that time—older models could no longer be sold, and manufacturers had to install more advanced catalytic converters and OBD systems. These standards drove upgrades in automotive technology and raised public awareness about environmental protection. Although China VI standards are now in place, looking back at 2007 as a pivotal year shows genuine improvements in air quality. My advice: when checking used car information, remembering that China III-compliant vehicles faced sales restrictions from that year onward can be very helpful. Overall, this move was timely and had far-reaching impacts.
Simply put, the China III emission standard was implemented in July 2007, marking the third phase of automotive environmental regulations. Its purpose was to control the emission of harmful substances such as particulate matter and hydrocarbons. After implementation, new vehicles had to meet the standard to be registered, which promoted more efficient engine designs. Looking back, this standard made both diesel and gasoline vehicle designs cleaner and also drove improvements in fuel quality. Today's stricter emission tests during annual vehicle inspections trace their origins back to China III. If you're concerned about car prices, the value of older China III-compliant vehicles has dropped significantly due to its impact on resale value and usable lifespan. In short, 2007 was a milestone year.
The China III emission standard was implemented in 2007, specifically starting on July 1st. I've reviewed the relevant documents—it imposed strict requirements on new vehicle emissions to reduce pollutants like PM2.5. The automotive industry underwent major adjustments at that time, with older models being phased out. Current new vehicle emission regulations are even stricter, but China III laid crucial groundwork that affects annual inspection pass rates. I recommend paying attention to the implementation dates of subsequent standards like China IV.
