Rolls-Royce Solutions 12V2000G85 – twelve-cylinder V diesel engine from mtu in Friedrichshafen: EPA nonroad certification, 809 to 890 kW, higher-rated generator version, Tier 2, model years 2012 to 2020
Rolls-Royce Solutions runs the mtu Series 2000 range, whose large diesel engines are built in Friedrichshafen on Lake Constance in southern Germany. The 12V2000G85 designation is the twelve-cylinder V version of this range in a generator variant tuned to a higher output than the G45 type, at the same cylinder count and basic dimensions. This page gathers the 12V2000G85 versions listed in the EPA register.

The register lists here five versions (12V2000G85, 12V2000G85 TB 3B, 12V2000G85 TB 3D, 12V2000G85 TD 3B, 12V2000G85 TD 3D) with 809 to 890 kW rated output at a constant 1,800 rpm, as a twelve-cylinder V engine with 130 mm bore and 150 mm stroke. The turbocharger is a waste-gate design, injection is direct, and the specified fuel is low-sulphur diesel at 300 to 500 ppm sulphur. The range is certified to Tier 2, for model years 2012 to 2020; maximum torque ranges from 4,292 to 4,721 Nm at 1,800 rpm.
With its higher power step, the 12V2000G85 serves larger stationary and mobile generator sets, for example for hospitals, data centres and large industrial plants with high backup demands; mtu competes here with Caterpillar, MAN and Cummins for large-genset applications.
On a used purchase, actual operating hours matter, since standby generator sets in this power class often run only in testing or emergency duty; also important are the condition of the waste-gate turbocharger, the tightness of the charge-air ducting, the cooling system and generator coupling, and a complete service record through mtu or Rolls-Royce service.
