Tier 4 range

  • 19-Apr-2011 03:02 EDT

In the range up to 560 kW (750 hp), Tognum subsidiary MTU supplies EPA Tier 4 Interim engines of Series 400, 500, and 900 with selective catalytic reduction (SCR). From 2014, MTU plans to introduce new Tier 4 Final engines of the Series 1000, 1100, 1300, and 1500 equipped with exhaust gas recirculation (EGR), SCR units, and diesel particulate filters. Also from 2014, the future Series 1600 engines (12V 1600 C is pictured) will extend the program up to 730 kW (980 hp). For Tier 4F requirements, these engines will be equipped with EGR and a diesel oxidation catalyst. The new generation of Series 2000 C&I engines for Tier 4I ranges from 561 to 1163 kW (752 to 1560 hp) and fulfills the emissions limits using only in-engine technology. They reportedly use up to 10% less fuel than their predecessors and feature a larger performance map, two-stage turbo system, and new common-rail fuel injection system. Series 2000 will be available in Tier 4F versions from 2015. Also from 2015, the new-generation Series 4000 engines for Tier 4 will cover the 800- to 3000-kW (1070- to 4020-hp) range with 8-, 12-, 16-, and 20-cylinder versions.
