8. Fast Load Acceptance - Capability to take Step Load
Load Step Capabilities.
- Superior load step capabilities, allowing for optimal operation even when isolated from the
utility or in stand-alone mode
- The quick-loading characteristics, typically found only in diesel engines, avoid the time-
consuming task of slow and gradual loading
- Loading capabilities with more than 50% load steps on rich-burn engines
Typical loading capabilities operating in island mode - rich-burns unique capability:

9. Fuel Flexibility
Capability to run on Variable Quality Field Gas and Low methane number
Waukesha rich-burn engines operate with a wide
margin for both knock and misfire, allowing a high
tolerance for fuel composition. At lower NOx levels,
lean-burn engines operate in an increasingly narrow
window, limiting fuel flexibility and making them more
sensitive to site conditions.

10. Better Fuel Efficiency
• Lower Fuel Consumption than Traditional Rich Burn
• As NOx approaches 0.5 g/BHP-hr and below, Waukesha rich-burn engines can operate more
cost effectively than competing lean-burn engines, since fuel consumption for lean burn engines
increases and efficiency decreases as combustion deteriorates due to the high amount of excess
air used to lower NOx

11. Low Emissions across Varying Applications
Rich-burn engines with a 3-way catalyst (NSCR) that provide a scalable emission solution with
the lowest overall emissions in the market.

12. Advanced Monitoring & Diagnostics
Proven ESM control system
-Dramatically reduces on-site setup time and requirements.
-Single, closed-loop control system integrating all engine
functionality
-Starting and loading the engine takes only a few minutes
-Once running, an HMI panel provides an easy-to-read display of
engine operating parameters
-ESM integrates air-fuel ratio, spark timing control, speed governing,
industry leading individual cylinder knock detection, start-stop logic,
diagnostic tools and fault logging
-The patented ESM system also manages speed and load control and
provides E-Help solution management software to pinpoint system
alerts
The Result. Maximum Uptime. Complete Engine Protection.
