MTU: The Single-Engine Solution for 90+ Years
Click above to learn more about MTU's rich history in rail applications.
MTU introduced its first diesel engine for rail applications over 90 years ago. Since the year 1950, MTU has delivered more than 16,500 engines for drive systems and electricity generation in railway vehicles worldwide. Time and time again they have proven their absolute reliability and uncompromising economic efficiency over hundreds of millions of miles of track.
Their extensive experience acquired after decades of developing the world's leading diesel engines is one of the main reasons KLW chose MTU. Locomotive and power-car manufacturers around the globe trust MTU as their power provider and today MTU engines are being much more common in the North American rail market. This is partially because MTU offers the lowest-emitting single-engine locomotive solution without aftertreatment, emitting up to 50% less than some of its competitors, and up to 90% less compared to older locomotive engines.
Series 4000: For Medium to Large GP and SD Applications
MTU's Series 4000 engines are perfect for demanding industrial, switching, and road-switching operations. These engines are high-speed (up to 1,800 RPM) and come in 12V (2,400 BHP) and 16V (3,200 BHP) configurations. They feature a separate circuit for charge-air cooling, common-rail fuel injection, cooled exhaust-gas re-circulation, and meet EPA Tier 3 line haul locomotive standards without the use of aftertreatments such as urea or diesel particulate filters. More impressively, these engines are the only engines in their horsepower class to also meet Tier 3 switch standards without aftertreatment. In addition to reducing emissions by up to 85%, these engines also consume up to 20% less fuel, saving operators tens of thousands of dollars per year in most applications. The Series 4000 engines have been installed in over 2,400 locomotives around the globe and are common in other industries with over 39,000 units produced to date. KLW uses the Series 4000 engines in our KLW SE24B and KLW SE32C models.
Series 2000: For Smaller SW, MP, and GP Applications
The MTU Series 2000 16V & 12V diesel engines, used in the KLW SE15B and SE10B, are 1,560 BHP and 1,050 BHP respectively and operate at up to 1,800 RPM. Certified to EPA Tier 4i non-road standards, these engines are some of the lowest emitting engines to be used for rail applications. With estimated emissions reductions of up to 90%, Series 2000 engines are excellent solutions for switching in highly populated areas where air quality is a concern. As a result, the KLW SE15B and SE10B qualify for many government-funded emissions-reduction programs.
In addition to ultra-low emissions, the MTU Series 2000 engines offer reductions in fuel consumption by 30-50% compared to many similar horsepower locomotives and up to 60% compared to higher horsepower locomotives which can possibly be replaced due to improvements in tractive effort. For most operations, this means savings in the tens of thousands of dollars or more per year for fuel consumption alone.
Global Engineering, Made in America
With headquarters in Germany, many think MTU engines are made and designed outside of the United States. The truth is MTU has manufacturing facilities around the world and these facilities collaborate together on the design and manufacturing of MTU's product line. The Series 2000 and 4000 engines used in KLW locomotives are made in Aiken, South Carolina which is a short drive from Augusta, Georgia. The facility in Aiken is over 270,000 sq. ft. and has expanded over the past few years, with the most recent addition being two new test cells which have doubled the capacity for testing new diesel engines. The Aiken facility currently employs over 300 people and holds ISO 14001 and ISO 9001 certifications.
