GE’s Waukesha Gas VGF

For nearly three decades, Waukesha’s VGF* line of engines has consistently performed under extreme conditions in a wide range of both power generation and gas compression applications.

The VGF series of high speed engines are built with the durability expected from a medium speed engine.

Purposefully designed for a wide range of stationary, spark ignited, gaseous fuel applications, the compact VGF engine has a high power to weight ratio. The foundation for exceptional long term performance is attributed to the core VGF family design.

  • Rich burn & lean burn combustion choices for maximum operational flexibility
  • Normal maintenance intervals for spark plugs, lube oil and filter changes are two to three times the hours of other brands
  • Only engine in its class offering field access to the bottom end for onsite major overhaul capabilities
  • Unsurpassed fuel flexibility

Low Emissions
High compression ratio lean burn configuration VGF engines are capable of operating 1g/bhp-hr NOx emissions even at high altitudes. Lower emission levels can be reached with rich burn engines equipped with a 3-way catalyst. The new SE engines are available with  emPact emission solution at both 0.15 and 0.5 g/bhp-hr NOx, as well as with U.S. EPA mobile certification.
GL (1:11) High alt/low emissions option only for gas compression applications. Emissions data measurements are consistent with those described in EPA CFR 40 Part 89 Subpart D & E and ISO 8178-1 for measuring NOx, CO, NMHC, CH2O.
Load Step Capabilities
VGF engines have superior load step capabilities, allowing for optimal operation even when isolated from the utility or in stand-alone mode. The VGF Series' quick-loading characteristics, typically found only in diesel engines, avoid the time-consuming task of slow and gradual loading.
