Shock Tube Measurements of Ignition Processes in Diesel-Related Fuels and Additives

摘要

Results of a three-year program of basic research aimed at improving knowledge of the combustion kinetics behavior of diesel-related fuels are reported. The work is intended to develop a database of gas-phase chemical kinetic and two-phase spray reference measurements applicable to improving diesel engine modeling and performance. Research was conducted in two Stanford shock tube facilities and focused on two topics: (1) measurements of shock- induced ignition time and individual species concentration time-histories measurements during the combustion of diesel-related gas-phase fuels, and (2) fundamental studies of fuel sprays in a new aerosol shock tube using state-of- the-art optical diagnostic techniques.
