Argonne researcher Jim Sevik tightens the fuel rail on a natural gas direct-injection system at the lab. The engine is an automotive size single-cylinder research engine that operates with gasoline as well as natural gas.
Visiting IIT Professor Carrie Hall troubleshoots the engine wiring harness. The system can replicate speed and load conditions found during typical vehicle operation for both naturally aspirated as well as turbocharged engines.
The research group includes, from left to right, kneeling: Anqi Zhang and Lorenzo Bartolucci; standing: Thomas Wallner, Riccardo Scarcelli, Michael Pamminger, Jim Sevik, Tim Rutter, and Carrie Hall.
