By 2010, the Environmental Protection Agency (EPA) will require all medium- and heavy-duty vehicles to run cleaner. A lot cleaner. Nitrogen oxide (NOx) exhaust emissions — which contribute to acid rain, smog and greenhouse gas levels — must be reduced to 0.2g/bhp-hr, an 83% reduction from 2007 levels.
EPA Emission Standards History
EPA 2010 emissions standards require NOx exhaust emissions to be reduced by 83% from 2007 levels.
Thomas Built Buses and its engine partner, Cummins Inc., meet the EPA 2010 emissions requirements, while maintaining maximum fuel efficiency and engine performance. Our proven technology, Selective Catalytic Reduction (SCR), not only reduces NOx emissions to near-zero, but Cummins testing shows a 5-9% fuel economy advantage compared to In-cylinder exhaust gas recirculation (EGR). This proven, road-tested technology provides significant advantages for the environment, and for your bottom line.
