Research Interests

Dr. Naber joined MTU in August of 2004. Prior to joining MTU, he worked in the automotive industry on R&D of engine-management-systems for gasoline and diesel engines. He also worked at Sandia National Laboratories, CRF investigating sprays and combustion processes of diesel, natural gas, and hydrogen engines utilizing laser based diagnostics. He and fellow colleagues direct the Advanced Internal Combustion Laboratories (AICE) at the University. His research interests are in IC engines and after-treatment and the development and application of advanced experimental techniques, signal processing technologies, theoretical models, and embedded control to characterize the thermo-physical processes.

The areas under investigation include:

• Combustion processes and combustion control of hydrogen and hydrogen dual fuelled engines,
  
• Biofuels including ethanol with production from forest products and application in advanced combustion engines,
  
• Gasoline IC engine research and the development of physical based correlations and models,
  
• Development of combustion measurement techniques for diesel, gasoline, and HCCI and PPCI engines.
  
  In addition to the selected publication listed below, he has numerous patents in the area of controls, on-board-diagnostics and exhaust sensing utilizing multilayer ceramics in an electro-chemical calorimetric sensor for hydrocarbons and other constituents as applied to powertrain and engine systems.
