John Deere opts for Integrated emissions control

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.

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.

    With the introduction of Stage V/Tier 5 emissions regulations set for 2019-2020, depending on engine power output, FPT Industrial says that it will build upon its SCR-only strategy, remaining one of the few manufacturers not adopting Exhaust Gas Recirculation (EGR) to meet the standard. The Italian firm’s Hi-eSCR after-treatment system, already in use on Stage IV/Tier 4 Final engines, maximises in-engine combustion technology without using EGR. This saves weight, cost and space for the equipment manufacture

    The forthcoming Tier 4 emissions legislation represents a great leap forward in technology, Mike Woof reports A high-profile focus on sustainability and reduced environmental impact is sweeping the construction sector in the European Union (EU) and the US. The EU and the US will implement regulations for the lowest emission off-road machines in history, with Canada and Japan expected to release similar regulatory programmes this year. The legislation being introduced will transform the construction indu
