In order to help students and researchers predict or design the combustion property of a newly designed or synthesized organic compound, Keshavarz provides details of flash point, autoignition, flammability limit, and heat of combustion of different classes of combustible organic compounds.
This requires application of new materials and variable mechanisms on (IC) engines, such are variable compression ratio (VCR), variable valve train (VVT), fuel injection systems with variable injection timing that have the capability of split multi-injections, homogeneous compression ignition combustion (HCCI), controlled autoignition (CAI), etc.
