We conduct a variety of design, development, and evaluation programs on engines ranging from a few hundred to more than 7,000 horsepower. Locomotive, stationary power, off-road, military, and marine engines are operated on diesel, heavy oils, compressed pipeline natural gas, and methane from liquefied natural gas, LPG, hydrogen, and other zero carbon fuel. Our Large Engine Facility includes four test cells dedicated to large, high-horsepower engines and gen sets. We also maintain a locomotive exhaust emissions test center near downtown San Antonio.
