GE installed emPact on one of WBI Energy’s Waukesha L7044GSI engines at the Baker Booster station in Montana. Performance has exceeded expectations. Seven weeks after emPact was operational, it was still maintaining emissions below 0.10 g/bhp-hr for both NOx and CO—without manual adjustment—even as site conditions changed. Quarterly source testing performed ten weeks after installation showed no change in emission levels.

It helps us get the right mixture to the catalyst to help it convert. It requires less babysitting to meet emissions and holds the engine on-target better, which is an obvious need in meeting your air/fuel emission standards. emPact adjusts through varying conditions—both load and ambient—so it’s certainly much better than what we’ve had in the past.” The emPact emission control system is one trusted solution, from one trusted source.

GE's Waukesha* emPact Emission Control System imagination at work

7 With the emPact emission control system 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 is factory-designed to optimize the interaction between components, resulting in excellent system performance. emPact means advantages The emPact system is comprised of a Waukesha VHP engine, GE-supplied 3-way catalyst and air/fuel ratio control. Oxygen (O2) sensors read post-catalyst exhaust composition to automatically adjust the engine’s air/fuel ratio, keeping...
