VHP Series Four
with emPact Emission Control System
1500 - 2250 BHP (1119 - 1678 kWb)
GE’s Waukesha P9394GSI gas engine combines proven features
common to other Waukesha VHP engines with a series of design
enhancements and packaging improvements, resulting in the
highest horsepower output in GE’s Waukesha Series Four richburn engine portfolio.
Components such as the Waukesha ESM control system,
emPact emission control system, cylinder heads, valves, liners,
bearings, and connecting rods are common with those found on
other Series Four engines, allowing for simpler operation and
An enhanced combustion system provides lower exhaust
temperatures and improved fuel efficiency for decreased service
and operation costs while still maintaining the application
flexibility associated with rich-burn engines.
Packaging improvements include an engine-mounted lube oil
cooling and filter system, deep sump oil pan, single fuel inlet
connection, simplifi ed cooling connections and a high-capacity
oil pump.
Waukesha’s emPact Emission Control System combines an
engine, catalyst, and air/fuel ratio control, factory-designed for
optimal interaction and maximum performance. It consists of
a GE-supplied catalyst, pre- and post-catalyst oxygen sensing,
and differential temperature and pressure sensors. emPact’s
closed-loop control system measures the engine exhaust and
automatically adjusts the air/fuel ratio to keep the catalyst
operating at maximum efficiency, even as speed, load, fuel, and
ambient conditions change.
A full-color display panel provides real-time engine operating
parameters, including faults, alarms, and shutdowns. A logging
function allows all data—including catalyst temperature and
pressure differential—to be saved to a USB device to simplify
emissions reporting.
Series Four engines can reliably produce more power on the
hottest field gases, at the highest altitudes, and in the most
remote locations, all while delivering the lowest available
emissions when paired with a 3-way catalyst (NSCR).
