The e3 system is AGCO’s brand for selective catalytic reduction or SCR. AGCO introduced e3 before the 2011 Tier 4 regulation, because there was a market demand for powerful and fuel-efficient agricultural tractors. The exhaust gas recirculation or EGR option will remain until 2011, at which time it will no longer be in compliance, and production will end.
Energy: Since e3 equipped engines deal with the regulated pollutants after the exhaust gas has left the engine, these engines create more power. This is after-treatment.
Economy: When e3 was introduced, AGCO and Challenger Tractor advertised up to 15% savings versus competitive (tier 3, EGR) engines. In fact, testing was completed at the Nebraska Test Lab and the results (made public in December of 2009) showed that e3-equipped tractors save up to 17% over comparable tractors.
Ecology: In current Tier 3 products, e3 reduces particulate matter by up to 70% and brings the NOx emissions to near Tier 4 interim levels.
