New clean diesel technology is unveiled.
Ten years ago, the Environment Protection Agency (EPA) introduced Tier 4 emission standards, which were to be phased-in over the 2008-2015 period. The standards require that emissions of PM and NOx be further reduced by about 90%.
The latest particulate filters, exhaust gas recirculation, oxidation catalysts, selective catalytic reduction (SCR) and many in-engine strategies were revealed at CONEXPO-CON/AGG 2014 by a range of manufacturers in an effort to meet the regulations.

“What we’re seeing ... is the unveiling of the newest clean diesel technology for the iconic workhorses of every construction project - wheel loaders, backhoes, excavators and bulldozers - in many shapes and sizes that are able to work in the smallest spaces or move the heaviest loads of material," said Allen Schaeffer, Executive Director of the Diesel Technology Forum.
According to Schaeffer, with most construction and agricultural equipment being diesel powered, these machines are operating with more than 90% lower in emissions than a decade ago, without compromising efficiency and productivity.
Some excavators, bulldozers and wheel loaders are even operating with hybrid technology which was revealed at the exhibition.
