mtu 12V2000G45 (Rolls-Royce Solutions America) – generator diesel engine of the Series 2000 range: 12-cylinder V engine, 710 to 780 kW, 1,710 to 1,800 rpm, Tier 2, turbocharged
Rolls-Royce Solutions America distributes the diesel engines of the mtu brand, part of the Rolls-Royce Power Systems group, in the United States. The model designation 12V2000G45 follows mtu's own system: 12 denotes the cylinder count in V arrangement, 2000 the Series 2000 range, and G45 marks the generator execution of that range.

The register lists here five versions with 710 to 780 kW rated output at 1,710 to 1,800 rpm. The 12-cylinder V engine measures 130 mm bore and 150 mm stroke, maximum torque ranges from 3,767 to 4,356 Nm. The engines are direct-injection, turbocharged, Tier 2 certified and fall in the power category above 560 to 2,237 kW.
The 12V2000G45 forms the smaller twelve-cylinder version within the Series 2000 range in G45 tuning and covers the lower part of the upper power segment in standby and island-grid applications, where mtu engines are widespread alongside Cummins and Caterpillar generator sets. In this segment the G45 tuning rounds out mtu's offering alongside the higher-boost G85 tuning of the same range.
On a used purchase, operating hours and adherence to mtu's service intervals count, along with the condition of the turbocharger and charge-air ducting, the tightness of the high-pressure injection system, coolant quality and the condition of the generator coupling; parts and service run through the worldwide mtu service network of Rolls-Royce Power Systems.
