  3. Super ultra-low emission vehicle - Wikipedia

    en.wikipedia.org/wiki/Super_ultra-low_emission...

    Super ultra-low emissions vehicle (SULEV) is a U.S. classification for passenger vehicle emissions. The classification is based on producing 90% fewer emissions than the average gasoline-powered vehicle. [ 1 ]

  4. Ultra-low-emission vehicle - Wikipedia

    en.wikipedia.org/wiki/Ultra-low-emission_vehicle

    An ultra-low-emission vehicle (ULEV) is a motor vehicle that emits extremely low levels of motor vehicle emissions compared to other vehicles. In some jurisdictions it is defined in law; low and ultra low emission vehicles may be given tax or other advantages, [1] while high emission vehicles may suffer restrictions or additional taxation.

    Wien's approximation (also sometimes called Wien's law or the Wien distribution law) is a law of physics used to describe the spectrum of thermal radiation (frequently called the blackbody function). This law was first derived by Wilhelm Wien in 1896.

  7. Partial zero-emissions vehicle - Wikipedia

    en.wikipedia.org/wiki/Partial_zero-emissions_vehicle

    The super-ultra-low-emission vehicle (SULEV) standard is more stringent than the ultra-low-emission vehicle (ULEV) and low-emission vehicle standards. All emissions-related components, including the electric-propulsion parts of hybrid electric vehicles , must be warranted for 15 years or 150,000 miles.

  8. Health and environmental impact of transport - Wikipedia

    Cycling has a low carbon-emission and low environmental footprint. A European study of thousands of urban dwellers found that daily mobility-related CO 2 emissions were 3.2 kg (7.1 lb) of CO 2 per person, with car travel contributing 70% and cycling 1% (including the entire lifecycle of vehicles and fuels).

  9. Low emission vehicle - Wikipedia

    en.wikipedia.org/wiki/Low_emission_vehicle

    A low-emission vehicle is a motor vehicle that emits relatively low levels of motor vehicle emissions. The term may be used in a general sense, but in some countries it is defined in air quality statutes. Different groups of people ("go greens", "go with the flow" and "no greens") show different interest in low emission vehicles [1]
