EMD Generator Sets


Customers worldwide continue to choose the EMD E23 for its significant advantages in power, durability, and responsiveness, which is unmatched in the industry.

The simple and robust design of EMD's two-cycle engine has stood the test of time by adapting to new demands and requirements. As part of Caterpillar, EMD continues to build on this legacy, committed to increased performance, durability, reliability and maintainability.


Unequalled performance for Power Generation:

The EMD two-cycle E23 engine is the most responsive generator set engine in the world. Testing proves our 5,000 horsepower 20-cylinder engine is able to accept full load in one step and recover speed in two seconds. By firing each cylinder once per revolution and benefiting from plentiful combustion air through our unique clutched turbo-changer design, the EMD E23engine is unique in its ability to smoothly accept load at any engine speed and at a rate no other medium speed engine in the world can match.

Emissions:  All EMD E23 engines are certified for U.S. Environmental Protection Agency (EPA) Tier 2 as well as IMO Annex VI Tier 1, and we already surpass IMO Tier 2 (effective 2011). EMD is developing solutions for U.S. EPA Tier 4 and IMO Tier 3 standards. The EMD two-cycle engine has responded well to the technologies required to meet these standards, and we expect to have more efficient and cost effective solutions due to inherent advantages of our 2-cycle engine design.
