Steve Ciatti is the principal investigator for investigating diesel and low temperature combustion (LTC) characteristics using endoscope in-cylinder imaging, at Argonne National Laboratory. Endoscope and fiber-optic imaging provides detailed information to evaluate combustion performance in both traditional diesel and LTC systems.
The engine Steve is currently working on is a state-of-the-art 2009 GM-Europe 1.9 liter direct injection diesel, operating on low cetane fuels (such as gasoline and gasoline blends) with up to 500% NOx reduction while maintaining diesel-like efficiencies (40+% BTE).
At Argonne, Steve also generated an internal project to utilize absorption spectroscopy and fiber-optics to develop a technique to measure combustion temperature under conditions that produce few emission-type photons. This approach utilizes a super-continuum laser to provide rapid scanning of the measurement control volume with minimal modification to the engine.
Along with his responsibilities at Argonne, Steve enjoys an adjunct position as Associate Professor of Mechanical Engineering at the University of Illinois, Chicago.
