Not-To-Exceed
The Not-To-Exceed (NTE) standard promulgated by the United States Environmental Protection Agency (EPA) ensures that heavy-duty truck engine emissions are controlled over the full range of speed and load combinations commonly experienced in use. NTE establishes an area (the “NTE zone”) under the torque curve of an engine where emissions must not exceed a specified value for any of the regulated pollutants. The NTE test procedure does not involve a specific driving cycle of any specific length (mileage or time). Rather it involves driving of any type that could occur within the bounds of the NTE control area, including operation under steady-state or transient conditions and under varying ambient conditions. Emissions are averaged over a minimum time of thirty seconds and then compared to the applicable NTE emission limits.〔Dieselnet, "Applicability and Test Cycles", Emission Standards » United States Heavy-Duty Truck and http://www.dieselnet.com/standards/us/hd.html〕
==Creation of NTE==
NTE standards were created by the EPA as a result of a consent decree between the EPA and several major diesel engine manufacturers. These manufacturers included Caterpillar, Cummins, Detroit Diesel, Mack, Mack's parent company Renault Vehicles Industriels, and Volvo Truck Corp. These manufacturers were accused of violating the Clean Air Act by installing devices that defeat emission controls.〔Mike Osenga, "Diesel industry confronts the emission settlement EPA enforcement of the Clean Air Act affects entire diesel engine industry)(Industry Overview)", ''Diesel Progress North American Edition'', (Published 12 January 1998) http://www.encyclopedia.com/doc/1G1-53919838.html〕 As part of the resulting consent decree settlement with the EPA, these manufacturers were assessed heavy fines and were subjected to new emissions standards which included NTE.
