  2. United States vehicle emission standards - Wikipedia

    en.wikipedia.org/wiki/United_States_vehicle...

    The Tier I standard was adopted in 1991 and was phased in from 1994 to 1997. Tier II standards were phased in from 2004 to 2009. Within the Tier II ranking, there is a subranking ranging from BIN 1–10, with 1 being the cleanest (Zero Emission vehicle) and 10 being the dirtiest.

  3. Emission standard - Wikipedia

    en.wikipedia.org/wiki/Emission_standard

    Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. They are generally designed to achieve air quality standards and to protect ...

    The cycle simulates an urban route of 7.5 mi (12.07 km) with frequent stops. The maximum speed is 56.7 mph (91.2 km/h) and the average speed is 19.6 mph (31.5 km/h). The cycle has two phases: a "cold start" phase of 505 seconds over a projected distance of 3.59 mi at 25.6 mph average speed, and a "transient phase" of 864 seconds, for a total ...

    The NTE cap is set at 1.25 times the FTP emission limit as described in the subsection above. For 2005 model year heavy-duty engines, the NTE emission cap for NMHC plus NOx is 1.25 times 2.5 grams per brake horsepower-hour, or 3.125 grams per brake horsepower-hour. The basic NTE control area for diesel engines has three basic boundaries on the ...

    In Tier 2 and 3 cities the general waste is also mixed with biomedical waste. The latest guidelines for segregation of bio-medical waste recommend the following color coding: [ 16 ] Red Bag – Syringes (without needles), soiled gloves, catheters, IV tubes etc. should be all disposed of in a red colored bag, which will later be incinerated.

  9. Continuous emissions monitoring system - Wikipedia

    en.wikipedia.org/wiki/Continuous_emissions...

    2 emissions are measured in pounds per hour using both an SO 2 pollutant concentration monitor and a volumetric flow monitor. For NO x, both a NO x pollutant concentration monitor and a diluent gas monitor are used to determine the emissions rate in weight per volume or weight per heat value (for example lbs/million Btu, lbs/ft 3, kg/kWh or kg ...
