Siemens has launched its new gas engine E-series with a power output of two megawatts (MW). The SGE-86EM has been designed for the 50-Hz market and the SGE-86EM for the 60-Hz market. The new E-series engine has 12 cylinders and offers a large volume per cylinder, high displacement and best-in-class efficiency in the market. 

The Miller cycle, high-efficiency, Siemens SGE-HM Gas Engines range from 520 to 1240 kWb. This series represents a new concept in engine design with the advanced technology incorporated into the cylinder heads, valves, camshafts, and turbochargers. These components make this series of engines one of the most efficient, robust engines available for power generation and co- and tri-generation applications.
