Product catalog summary

Introduction
The Siemens E-Series Gas Engines offer a new best-in-class solution for efficient power generation in the 2 MW-class category. These engines provide the highest electrical efficiency with a compact design.

Specifications
The SGE-EM gas engines feature a unique high-volume 12-cylinder design, offering the highest displacement in its class. Key specifications include:

90,000 hours until overhaul
Innovative pre-combustion chambers for efficient combustion
Spark-ignited lean-burn unit for low emissions
Fast cycle times and implementation
Lowest emission version available at 200 mg NOx

Engine Models
Two models are available: SGE 86EM and SGE 100EM, both with V12 cylinder arrangements. Key differences include:

SGE 86EM: 86 liters displacement, 240 mm stroke, 19.2 bar BMEP
SGE 100EM: 100 liters displacement, 280 mm stroke, 20.7 bar BMEP

Both models deliver mechanical power of 2,065 kWb and electrical power of approximately 2,012 kWe, with mechanical and electrical efficiencies around 46.6% and 45.4%, respectively.

Design and Technology
The engines incorporate advanced design features for enhanced performance:

High-efficiency turbochargers and two-stage charge coolers
Water-cooled cylinder heads and exhaust valve seats
Direct gas injection in pre-combustion chambers
Nickel-chromium superalloy materials for high temperature resistance
Optimized cylinder liners and forged steel pistons for better combustion efficiency

Conclusion
The Siemens SGE-EM gas engines provide a competitive choice in the 2 MW-class market, combining high power and efficiency with a small footprint and innovative combustion technology.
