MAN Engines approves off-road engines for use with
regenerative diesel
According to MAN Engines, all MAN off-road engines from the current
product portfolio can be operated with regenerative diesel—also known
as HVO (hydrogenated vegetable oil)—in accordance with the EN15940
standard in Europe or the US specification ASTM D975. By burning
regenerative diesel, engines emit up to 30% less particulate matter
and up to about 10% less nitrogen oxides (NOx).

The approval applies to all off-road engines for
the current EU Stage V and EPA Tier 4 emission standards and below.
Marine engines for regenerative diesel have already been approved.
Customers can use it to replace—or mix—conventional diesel fuel
and use MAN engines with green or renewable diesel. This is obtained
on the basis of waste and residues of animal and plant origin,
cellulosic biomass materials such as crop residues, among others.
Above all,
regenerative diesel ensures clean combustion with up to 90% less
greenhouse gas emissions in the exhaust gas compared to conventional
diesel.
—Mikael Lindner, Head of MAN Engines
There are
no performance losses or disadvantages with regard to the service and
maintenance intervals of our MAN engines, and the AGN also works
without any problems.
—Werner Kübler, Head of Engineering at MAN
Engines
The use of said regenerative fuel has no negative effects either on
system components or on the efficiency of the drive system or any
existing exhaust gas aftertreatment systems.
In addition, due to its similar chemical composition to fossil
diesel, the use of HVO does not require any modification to existing
vehicles or refueling station infrastructure. This can be refueled
pure, i.e. 100% as HVO100, or with an admixture—at any mixing ratio—of
conventional diesel fuel.
At the end of February 2023, the German government decided to
include DIN EN 15940 in the “10th Ordinance on the Implementation of
the Federal Immission Control Act” (BImSchV). This means that these
synthetic fuels can be sold in their pure form at public filling
stations.
In addition to the use of regenerative fuel/HVO, the MAN
off-road engines are also approved for R33 fuel, which contains 33% of
regenerative components. Of these, 26% are hydrogenated vegetable oil
(HVO) and 7% are rapeseed methyl ester (RME). The remaining 67% is
made up of high-quality diesel fuel in accordance with DIN EN590.
The current and former off-road engine series MAN D2862, D2842,
D2868, D4276, D3876, D2676, D2876, D2866, D1556 LE, D0836 and D0834
have been specifically approved for use with regenerative diesel. This
is the complete power range of MAN off-road engines from 160 to 1,110
hp (118 to 816 kW). These are operated in accordance with the emission
guidelines of the US Environmental Protection Agency or the European
Union (EU).
