John Deere Power Systems unveiled its solution for EU Stage IV emissions regulations at INTERMAT.
It saw the company introduce an SCR catalyst and diesel exhaust fluid dosing unit to its Stage IIIb engine platforms from 56-560kW. “SCR was not our preferred technology path but it has proved to be the best way for us to maintain particulate levels while reducing NOx to meet EU Stage IV emissions regulations,” explained Xavier Adam, market planning manager for John Deere Power Systems.

MAN has revealed two new ranges of off-highway engines that are said to lay the foundation of its EU Stage V emissions regulation strategy. The two ranges include a six-cylinder 15.26 litre engine offering outputs from 415-485kW and a larger 24.24 litre V12 engine with power outputs from 588-816kW. Both meet Tier 4 Final/EU Stage IV emissions and are also said to be EU Stage V ready. The six-cylinder engine, badged D3876 LE12x, uses variable geometry turbocharging and a 2,500 bar fuel injection pressure to
There has been significant focus on alternative power solutions for off-road vehicles and equipment such as hybrid, full electric and hydrogen. Whilst these solutions will be suitable in the long term, it will take time for these technologies to be competitive and enable wider adopted in the construction industry.
