An engine manufactured by an Indiana company and which will be used in passenger locomotives has been certified a meeting Tier 4 emission standards.
Cummins Inc., based in Columbus, Indiana, said its QSK95 locomotive engine is the first single prime power engine certified to Tier 4 standards by the U.S. Environmental Protection Agency.
The QSK95 is rated at 4,400 horsepower and the 16-cylinder high-speed diesel engine achieves Tier 4 status through a modified direct fuel injection system and the urea-based after treatment.
The engine is being installed in the Charger passenger locomotives being assembled in Sacramento, California, by Siemens.
The Charger locomotives will be used on Amtrak corridor routes in Illinois, California, Missouri, Washington, Michigan, Wisconsin and Oregon.
The Charger will also be used by commuter rail agencies as well as the Brightline rail service between Miami and Orlando, Florida.
Cummins is testing a freight version of the engines in a modified SD90MAC locomotive on the Indiana Rail Road.
“We’re pleased to have reached this milestone,” says Jim Trueblood, Cummins vice president of the high-horsepower engine program. “Cummins is committed to bringing clean, efficient, durable engines to every market we serve.”
