VHP* Series Four*
L5794GSI
with ESM2 and emPact Emission Control System
920 - 1380 BHP (686 - 1029 kWb)
Engine supplied with 3-way catalyst but without exhaust piping.
Engine-out and catalyst-out exhaust piping shown for illustrative
purposes only.
GE’s Waukesha Series Four rich-burn engines are the engines of
choice for the harshest and most demanding gas compression,
power generation and mechanical drive applications. The
Series Four engines can reliably produce more power on hot
field gases, at high altitudes, and in remote locations, all while
delivering low emissions when paired with a 3-way catalyst
(NSCR).
ESM*2 is GE’s next-generation engine controller, adding
functionality and benefits to the proven ESM platform.
The ESM2 customer interface is a 12” full-color touch screen
display panel that allows users to see all engine parameters,
trend data, view manuals, and walk through troubleshooting
steps, eliminating the need for a laptop computer.
Enhanced misfire detection can capture a single misfire event
and an enhanced three-dimensional timing map allows for
tighter engine control over the entire range of fuels.
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.
ESM2 directly reads exhaust and main bearing temperatures
sensors and adds crankcase pressure, boost pressure, and
an oil pressure permissive for starting the engine to the list of
sensors available with the previous version of ESM.
