Production Test Shows GE Engine Meets Tier 4 Emissions Standards

GE TransportationGeneral Electric Transportation says the first production test of its GE Evolution Series Tier 4 engine shows that its newest engine meets the EPA’s Tier 4 locomotive emissions standards, which took effect on Jan. 1, meeting nitrogen oxides (NOx) and particulate matter (PM) emissions reductions by at least 70 percent from Tier 3 emission standards.

The production test evaluates the performance, emissions and mechanical properties of the engine. This is the first engine to go through the newly built test cell in Grove City, Pennsylvania, and will be sent to one of GE’s locomotive assembly facilities to be installed into a GE Evolution Series Tier 4 locomotive.

The new test cell, built specifically for the Tier 4 engine, is equipped to improve technology and tooling that test for performance and Tier 4 emissions levels, GE says.

The development of the Evolution Series Tier 4 engine was part of the larger $600 million investment made in the Evolution Series platform that allowed GE to create an engine that required no after-treatment to meet the emission targets.

GE Transportation leveraged other GE business units to develop elements of the Tier 4 engine including the power assembly, exhaust gas recirculation, common rail fuel system and turbocharger.
