CEG member Peng Zhao from the Department of Mechanical and Aerospace Engineering lead a discussion on combustion energy at our fourth CEG lunch.

The discussion covers some of the research frontiers in the field:

  1. New engine technology: using low temperature combustion techniques to achieve low emission of both NOx and soot, e.g., HCCI engines;
  2. New alternative fuel: biodiesel as an alternative fuel, and also its effect on soot reduction;
  3. Nanotechnology in combustion: a) Using flame synthesis technique to produce nano particles and other nano structures; b) Application of nanoparticle catalyst to facilitate ignition in scramjet engine.
