REDUCING EMISSIONS IN THE TIER 4 LOCOMOTIVE

Tier 4 loco

Engineers from GE Transportation and GE Global Research spent several years in the lab, building and experimenting with a new engine design. The team at GE Global Research built a single cylinder engine for testing, gathered detailed measurements of the exhaust and plugged the information into custom software models designed to simulate a full-scale engine. Engineers found that it was crucial to keep the temperature inside the cylinder at an optimal level to reduce NOx and PM. They devised an ingenious system that pipes in some of the hot exhaust gas to keep the engine at the desired temperature. Today, GE’s new Tier 4 Evolution Series Advance Power 4, ecomagination certified locomotive, is the only engine that meets the EPA’s Tier 4 requirements without any after-treatment technology. With no need for a filter or a converter, it’s truly a game changer in the industry.

MAKING A DIFFERENCE WITH MATERIALS

LEAP engine

“LEAP IS THE FASTEST-GROWING ENGINE IN OUR HISTORY.” Ceramix Matrix Composites play a key role in the performance of the CFM LEAP,* the jet engine that will power the next generation of narrow-body aircraft. Advanced manufacturing has helped improve part durability, decrease engine weight, and increase fuel efficiency, allowing airlines to save as much as $1.2M a year in costs per plane. *The LEAP engine is made by CFM International, a 50/50 joint company of GE and Snecma (Safran) of France.

THE ENGINE FOR INNOVATION

HA Turbine

A 62.22% efficiency rating for a combined-cycle power plant has never been achieved before…until now. GE, with the partnership of EDF, just made history and set a Guinness World Records™ title for powering the world’s most efficient combined-cycle power plant (achieved 28 April 2016) in Bouchain, France. The Bouchain plant - which officially began operation on June 17 - is also the world’s first combined-cycle plant equipped with GE’s HA turbine.
