In the United States, the emission standards for non-road diesel engines are published in the US Code of Federal Regulations, Title 40, Part 89 (40 CFR Part 89). Tier 1–3 Standards were adopted in 1994 and was phased in between 1996 and 2000 for engines over 37 kW (50 hp). In 1998 the regulation included engines under 37 kW and introduced ...
Emission Standards. The NO x and PM Law introduces emission standards for specified categories of in-use highway vehicles including commercial goods (cargo) vehicles such as trucks and vans, buses, and special purpose motor vehicles, irrespective of the fuel type. The regulation also applies to diesel powered passenger cars (but not to gasoline ...
The emission standards for trucks (lorries) and buses are defined by engine energy output in g/kWh; this is unlike the emission standards for passenger cars and light commercial vehicles, which are defined by vehicle driving distance in g/km — a general comparison to passenger cars is therefore not possible, as the kWh/km factor depends ...
The Environmental Protection Agency on Friday set strict emissions standards for heavy-duty trucks, buses and other large vehicles, an action that officials said will help clean up some of the ...
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 ...
That bill was the Voinovich-Carper Diesel Emissions Reduction Act of 2010, which was the 3973 bill heard by the 111th Senate.
