The case for a rich-burn engine just got more powerful


Introducing GE’s Waukesha* VHP* P9394GSI, combining the benefits of rich-burn performance with the advantages of lean-burn efficiency


The VHP* P9394GSI enhanced rich-burn engine is breaking new ground as an exceptionally adaptable solution engineered for today’s applications. Based on Waukesha’s proven L7044GSI and P9390GSI, the P9394GSI extends the rich-burn advantage by combining fuel flexibility and ultra-low emissions capability with the efficiency of a lean-burn engine. This unmatched combination makes the P9394GSI an ideal engine solution for long-term, reliable performance that minimizes environmental impact while maximizing profits.

Engine advantages


Better performance with operation on fuels up to 2300 BTU/ft3 and fuel consumption


of 7063 BTU/bhp-hr, which lowers operating costs and CO2e emissions.lied 3-way catalyst for emissions down to 0.15 g/bhp-hr NOx and 0.30 g/bhp-hr CO.


NOx emissions less than 0.5 g/bhp-hr


Next generation AFR2 system includes O2 sensors optimized for natural gas and fullcolor HMI panel displays engine operating parameters without a laptop. Optional emPact Emission Control System adds GE-supplied 3-way catalyst for emissions down to 0.15 g/bhp-hr NOx and 0.30 g/bhp-hr CO.
