Waukesha* emPact Emission Control Upgrade

With the emPact emission control upgrade for Waukesha VHP* gas engines, GE effectively combines all the emissions-related components of an engine into one comprehensive control system that can keep your emissions in compliance. The system uses a special oxygen (O2) sensor specifically designed for natural gas operation and is factory-designed, tested, and calibrated to improve the interaction between components, resulting in excellent system performance.

  • Emissions

Customer benefits

  • Automatically adjusts to achieve and maintain emissions compliance
  • Lower catalyst-out emissions mean more allowable HP per site without triggering tons-per-year limits such as Title V
  • Decreased potential for damage and increased catalyst life through differential pressure and temperature catalyst sensors
  • Time and labor savings

How We Get You There

Key components included:

  • Stainless steel catalyst housing
  • Catalyst access door
  • Catalyst wiring harness
  • Heat shield
  • Full authority fuel valve
  • Post-catalyst oxygen sensor
  • Pre-catalyst pressure sensors
  • Post-catalyst pressure sensors
  • Pre-catalyst temperature sensor (behind heat shield)
  • Post-catalyst temperature sensor (behind heat shield)
  • 4.5-inch color display panel Emission Control Module (ECM)
