Rolls-Royce releasing mtu rail engines for sustainable fuels


Rolls-Royce is releasing mtu rail engines to be used with sustainable fuels. With artificial diesel fuels of the EN15940 normal, CO2 emissions could be decreased by as much as 100% in comparison with fossil diesel. Hydrotreated Vegetable Oil (HVO or renewable diesel), which is already commercially obtainable at this time, reduces CO2 emissions by as much as 90%. If the fuels are produced with the assistance of renewable power and inexperienced hydrogen—via what’s termed a Energy-to-X course of—current rail autos could be operated in a totally CO2-neutral method.

The mtu Sequence 1800 engines that are utilized in mtu PowerPacks, in addition to Sequence 1300 and 1500 for locomotives and multi-purpose autos, are already authorised to be used with artificial fuels comparable to HVO. Sequence 1600 and variations of Sequence 4000 engines will observe within the close to future.

The discharge of engines for climate-friendly fuels requires a collection of exams and trials and Rolls-Royce has discovered robust companions for this exercise. DB Cargo and RDC Autozug Sylt have already examined or are at present testing mtu Sequence 4000 engines with HVO of their locomotives.

HVO permits our prospects to considerably scale back their greenhouse gasoline emissions with current autos and engines and to make an necessary contribution to local weather safety at this time. Emissions of soot and nitrogen oxide are additionally considerably decreased—with out having to make any adjustments to the drive system or infrastructure. No important adjustments in efficiency had been noticed and availability and repair lifetime of our engines stay unchanged, which is very enticing for our prospects.

Together with our mtu Hybrid PowerPack, HVO permits not solely low-CO2, but in addition regionally emission-free and virtually silent operation. This makes it doable to realize local weather and environmental safety targets with current autos and with out the necessity for complicated and costly adjustments to infrastructure.

Since mid-August 2021, DB Cargo, in coordination with Rolls-Royce, first performed engine bench exams after which operational trials, for instance with DB Sequence 294 locomotives with an 8V 4000 R41 mtu engine operating on HVO. After greater than 1,800 working hours, the outcomes are promising.

We had been in a position to make use of HVO with none issues in our autos, with out compromising efficiency and reliability.

The analysis of one of many engines after completion of the sphere check is scheduled to happen in September 2022, after which Rolls-Royce will promptly launch the extensively used mtu rail engines of the categories 4000 R01 and R03 for artificial diesel fuels of the EN15940 normal, together with HVO. DB Cargo additionally makes use of HVO in different locomotives in its fleet.

RDC Autozug Sylt and Rolls-Royce lately began HVO discipline trials with a Vectron DE diesel-electric locomotive outfitted with an mtu engine of sort 4000 R04, which meets the strict EU Stage IIIB emission rules for rail drives.

Following the profitable completion of the exams with RDC, Rolls-Royce additionally intends to usually launch the Sequence 4000 R04 engines to be used with HVO and different EN15940 artificial diesel fuels, as early as 2023. RDC is already utilizing HVO in different providers since July 2022.

Rolls-Royce introduced in 2021, as a part of its sustainability program “Internet Zero at Energy Techniques”, that it will realign its product portfolio in order that by 2030, new fuels and mtu applied sciences can scale back greenhouse gasoline emissions by 35% in comparison with 2019.
