Product catalog summary
Overview: The document provides comprehensive specifications and power ratings for GE's Waukesha gas engines, focusing on models like the P9394GSI and 275GL*+. It details engine displacement, bore and stroke, compression ratios, and power outputs at various RPMs.
Specifications: It lists multiple engine models with their respective displacements, bore and stroke dimensions, and compression ratios. For example, the 16V 275GL+ has a displacement of 17,398 in3 (285 L) with a bore and stroke of 10.83 x 11.81 inches (275 x 300 mm) and a compression ratio of 9:1.
Power Ratings: Power outputs are provided in brake horsepower (bhp) and kilowatts (kWb) across different RPMs. For instance, the 16V 275GL+ engine produces 36,255 bhp (27,035 kWb) at 750 RPM and 48,355 bhp (36,055 kWb) at 1000 RPM.
Engine Types and Applications: Engines are categorized based on applications such as gas compression, mechanical drives, and power generation. It distinguishes between continuous and intermittent duty ratings, specifying conditions for overload operation.
Operational Notes: Notes on operational conditions include permissible overload durations and the impact of intercooler water temperature on performance. It mentions engines with Low Fuel Pressure Systems (LFPS) and adjustments for ambient and altitude conditions.
Fuel Types: Engines are designed to operate on natural gas, with some models capable of using alternative fuels like bio-gas and HD-5 propane. Specific notes on fuel standards and engine efficiency are provided.
Generator Ratings: Power generation ratings are detailed for both continuous and standby operations, with specific kWe outputs listed for different engine models and configurations.
Additional Information: The document advises contacting GE Energy Application Engineering for specific power unit ratings and stability in power generation applications.
Engine Specifications: Detailed specifications for various Waukesha engine models, including displacement, bore and stroke dimensions, compression ratios, and power outputs at different RPMs. Key models include the L7044GSI, L7042GSI, L5794GSI, F3524GSI, and others.
Engine Model Prefix and Suffix Designations:
  • Prefix: Indicates the number of cylinders, except for the 275GL model which states the actual number of cylinders. For example, 'P' denotes 16 cylinders, 'H' denotes 8 cylinders, 'L' denotes 12 cylinders, and 'F' denotes 6 cylinders.
  • Suffix: Describes the engine's configuration and features, such as 'G' for naturally aspirated, 'GSI' for turbocharged intercooled, 'GL' for turbocharged intercooled lean burn, and others.
