257 John Deere Power Systems, has completed its Stage IV engine line-up, now offering 2.9-litre, 4.5-litre, 6.8-litre and 13.5-litre engines with power outputs of 30kW to 448kW. The company is using three Integrated Emissions Control system configurations to meet the Stage IV/Tier 4 Final standard.

For engines in the 36-55kW range John Deere is using an exhaust filter that contains a DOC and a DPF, but without exhaust gas recirculation (EGR) or SCR. The 56-104kW engines are equipped with cooled EGR and the Integrated Emissions Control system, containing SCR and a DOC.

Deere’s engines above 93kW will have the emissions control with cooled EGR, a DOC/DPF and SCR.

The company believes that this modular approach will allow it to meet Stage V regulations when they arrive in 2019/2020. It will however retain the two box approach, rather than trying to fit DOC, DPF and SCR systems into a single module.

“We know how Stage V will go so far and we are very confident about our ability to meet the standards with very little modification,” said OEM sales manager Patrick Thil.

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
