| Abstract: | Progress to date is reasonably within the contract schedule in that: (1) the transparent-piston, transparent-head engine is in routine use for visualization experiments; (2) the gaseous fuel injector is routinely used with gaseous propane as a fuel injected into the motored engine; (3) high speed filming and short duration pulsed light single exposure techniques are being used to obtain shadow and schlieren records of gaseous and liquid jets; (4) an LDV system for measuring in-cylinder velocities has been implemented and data is presently being taken and analyzed; (5) engine cylinder pressure data can now be taken and reduced with the minicomputer; and an infrared emission absorption technique has been used to measure engine cylinder temperature; (6) an alternative approach to the modeling of gaseous jets has yielded a characteristic time for steadying of the jet, which in the long run should allow a more efficient computational procedure; (7) work on the definition of appropriate equations for thick sprays has continued; (8) two DISC meetings have been attended, one of which was hosted by Princeton, and the results of the program have been made known to researchers and automotive industries; and (9) the pulsed illumination television system has been successfully used to obtain visual data on engine cyclic variations. |
