Sulev Emissions Standards
Sulev Emissions Standards. Combined, the emission measures achieve robust and efficient emission control. Emission standards are for the major pollutants in vehicle exhaust:

Exhaust emissions standards 5 directive text number euro 1 (ec 93) 1) euro 2 (ec 96) euro 3 (ec 2000) euro 4 (ec 2005) 91/441/eec or 93/59/eec 94/12/ec or 96/69/ec 70/220/eec, as amended by 98/69/ec and 2003/76/ec Three sets of emission standards are defined as lev, ulev, and sulev. Bmw was the first of the major car manufacturers in the world that produced this kind of technology.

At the moment the sulev legislation is the most stringent emission regulation worldwide. Exhaust emissions standards 5 directive text number euro 1 (ec 93) 1) euro 2 (ec 96) euro 3 (ec 2000) euro 4 (ec 2005) 91/441/eec or 93/59/eec 94/12/ec or 96/69/ec 70/220/eec, as amended by 98/69/ec and 2003/76/ec Emission standards are for the major pollutants in vehicle exhaust:
A Fourth Emission Category, Pzev (Partial Zero Emission Vehicle), Had The Same Test Emission Levels As Sulev, But Also Included A “Zero” Evaporative Emissions Standard And A 150,000 Mile/15 Years Emission Durability.
Low emission vehicle (lev), ultra low emission vehicle (ulev), super ultra low emission vehicle (sulev) are the categories that remain, and are significantly more restrictive than before. Not all vehicles produced by bmw are sulev types. A fourth emission category, pzev (partial zero emission vehicle), has the same test emission levels as sulev, but also includes additional evaporative emissions control.
Sulevs Are Cleaner Than Ulev Certified Vehicles.
Tier 2 evaporative emission standards. The lev ii standards include lev (low emissions vehicle), ulev (ultra low emissions vehicle), sulev (super ultra low emissions vehicle), and pzev (partial zero emission vehicle), which have since been adopted by other states. As a standard, that makes it far stricter than the lev designation, which is now increasingly common as automakers race to achieve mandated emission level targets.
Tier 0, Tier 1, Nlev, And Cfv Exhaust Emission Standards.
Ultra low emission vehicle standards, in many states, applies to vehicles in model years 2003 to 2010. This paper describes a cold start emission reduction system developed for a 3.0l v6 test vehicle in order to meet sulev emission regulations. The whole sulev or super ultra low emissions vehicle standard started in cali to keep metro areas free from harmful particles.
In General, A Sulev Engine Is Considered 90% Cleaner Than Its Average Counterpart.
Which states are the n51 bmws sold in? Avl has shown, that the ambitious sulev30 emission targets can be achieved with both new as well as aged exhaust systems on the basis of a demonstration vehicle besides optimizing the combustion system itself the aftertreatment (eas) layout and optimization is The emphasis of this research is how the system can be used to meet sulev emission standards without the need for a heavily loaded catalyst.
