EMD Propulsion Engines

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.

 

Unmatched Performance for Marine Propulsion:

Fixed Pitch:  The EMD 2-cycle engine provides a large margin of available power above the demand curve to provide superior acceleration and responsiveness. By comparison, in the fixed pitch propeller applications, the available power of a typical four-cycle engine narrowly meets the propeller demand curve.

Controllable Pitch:  The additional power capacity of the EMD two-cycle engine enables it to accept virtually any pitch at any rate, without overload. Four-cycle engine manufacturers limit available engine power to levels significantly below their engine's continuous rating in order to protect against engine overload. 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.  Testing in marine applications has demonstrated acceleration from idle to full load in less than 11 seconds.

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.
