Advanced Reciprocating Engine Systems
The Advanced Reciprocating Engine Systems (ARES) program is designed to promote separate but parallel engine development between the major stationary, gaseous fueled engine manufacturers in the United States. The program promotes cooperation between engine manufacturers, universities, national laboratories, and engine consultants to obtain maximum engine efficiency and low emissions from natural gas reciprocating engines for power generation.
The ARES program focuses on improving reciprocating engines (piston-driven electrical power generation systems) in the 0.5-5 megawatt (MW) range. In collaboration with national laboratories, university research centers, and private companies, DOE has improved medium-speed natural gas engines for distributed energy applications. Current research aims to increase their energy efficiency, reduce nitrogen oxide (NOx) emissions, and reduce operating and maintenance costs. The program has made great progress in these areas, paving the way for more cost-competitive equipment.
Our researchers have tested engines and produced analytical computer models to upgrade engines, pistons, piston rings, and cylinder liners and to improve ignition systems and reduce friction. They have achieved a more comprehensive understanding of ignition systems, especially at the point of ignition and the beginning of the power cycle. As a result, they have designed, developed, tested, and produced advanced reciprocating engines that approach DOE performance targets for industrial and commercial applications. A number of these engine systems have been installed at commercial sites.

Research partners described their projects, shared objectives, and reported their progress during a Portfolio Review in June 2011.
