John Deere Tier 4 Final/Stage IV diesel engine

John Deere Power Systems (JDPS) will show its entire Tier 4 Final/Stage IV diesel engine line-up

257 John Deere Power Systems’ (JDPS) entire Final Tier 4/Stage IV diesel engine line-up can be seen with the company showing its familiar 3089 PowerTech displacements of 2.9, 4.5, 6.8, 9 and 13.5litres.

United States Final Tier 4 and 1116 European Union Stage IV emissions regulations for mobile off-highway diesel engines 56kW and above will be implemented in stages starting in 2014 and 2015. These standards maintain the particulate matter (PM) levels established by Interim Tier 4/Stage III B regulations while requiring an additional 80% reduction in nitrogen oxides (NOx) from previous regulations.

As announced in 2012 at Intermat, John Deere will continue with its planned building-block approach to meet the challenging Final Tier 4/Stage IV regulations, and to achieve compliance it has developed the Integrated Emissions Control system, a solution that is said to optimises engine performance, operating efficiency and reliability while offering flexibility to customers.

John Deere Power Systems completes engine line-up

John Deere Power Systems used bauma to complete its engine line-up for Tier 4 Final/Stage IV emissions regulations. This included the arrival of the PowerTechTM PWL 4.5L engine, which meets emissions regulations without a diesel particulate filter (DPF). Spanning outputs from 63-104kW, this four-cylinder, 4.5litre engine offers reduced cost and improves engine packaging by eliminating the DPF, said Deere. However, the engine uses selective catalytic reduction (SCR), a diesel oxidation catalyst (DOC) and coo
