Tecogen to Present Paper at SAE World Congress WA

WALTHAM, MA --(Marketwired - April 10, 2018) - Tecogen Inc. ( NASDAQ : TGEN ), a leading manufacturer of clean energy cogeneration products that, through patented technology, nearly eliminate criteria pollutants and significantly reduce a customer's carbon footprint, is pleased to announce that Tecogen Board Member and Ronald C. Crane Professor of Mechanical Engineering at MIT Ahmed Ghoniem, will be presenting a paper at the WCX™18: SAE World Congress Experience being held this week in Detroit, MI. Dr. Ghoniem, Tecogen Manager of Engineering Jean Roy, Tecogen President and Chief Operating Officer Robert Panora, and Tecogen Chief Technology Officer Joseph Gehret co-authored the peer-reviewed paper titled "NOx Reduction Using a Dual-Stage Catalyst System with Intercooling in Vehicle Gasoline Engines Under Real Driving Conditions."

The paper discusses a previously unidentified NOx removal mechanism in Tecogen's Ultera emission system. Test results have shown that the Ultera dual stage catalyst system removes up to an additional 30% of NOx from gasoline engine emissions over the standard US06 drive cycle compared to a single stage emissions system. The paper explains the mechanism behind the reduction.

"It is an honor and a privilege to present at the SAE World Congress," commented Robert Panora. "This is the second consecutive year that the SAE has provided us the opportunity to present a paper. Ultera is a groundbreaking emission aftertreatment system that has proven a unique ability to virtually eliminate criteria pollutants such as nitrogen oxides, hydrocarbons, and carbon monoxide from the emissions of modern stoichiometric internal combustion engines. We are eager to share our findings."

A copy of the report is available at the SAE website or upon request by contacting Tecogen Investor Relations .
