Rolls-Royce and Forest Tract, Saint Dizier France, a manufacturer of forestry machinery, have announced an agreement to cooperate on the supply of EU Stage 5 diesel engines.  MTU is part of Rolls-Royce Power Systems.

Rolls-Royce and Forest Tract finalized their partnership agreement in April. It provides the framework for a collaboration on MTU engines compliant with the EU Stage 5 emissions directive due to come into force in 2019. Taking Mercedes Benz OM 93x and OM 47x commercial vehicle engines as a basis, Rolls-Royce Power Systems and Daimler are to jointly develop MTU Series 1000, 1100, 1300 and 1500 units that comply with the EU Stage 5 off-highway emissions standard.

The MTU 6R 1000 units delivering 100 to 280 kW are suitable for powering all of Forest Tract’s skidder models. The MTU engines stay within the new soot particle limits through a combination of in-engine innovations with an SCR system and a diesel particulate filter.  An EU Stage V prototype is to be delivered in summer 2017.
