1. An investigation of the ignition delay time for oil - water emulsion additionalfuel as single droplets is conducted.

2. The ignition delay and temperature curves were measured with a rapid compression machine.

3. Results show that ignition delay time becomes longer as loading density of propellants and the distance between propellants and plasma jet increase.

4. The ignition delay fault of solid rocket motor happening in a low temperature based on FTA is analyzed in the paper.

5. Although the ignition delay period of E-diesel was postponed, the combustion duration was shortened and the mean indication pressure was enhanced.

6. The ignition delay period became longer while the sustained combustion period became shorter.

7. The ignition delay time was studied on the hot position bench that could stimulate combustion process of traveling grate furnace.

8. The ignition delay periods of methanol, isooctane, n-heptane and their blended fuel were studied based on their detailed chemical kinetic mechanism.

9. The problem of longer ignition delay for hydrocarbon fuel can be effectively solved by means of preheating fuel by shock waves and using hot gas as pilot.

10. High pressure can significantly reduce the ignition delay and combustion period.

11. If the ignition delay is too big, the propellants cant be burnt; if the ignition is too small, the improvement effects are small.

12. In order to determine the proper ratio of center charge with propylene oxide fuel (RCF) and ignition delay time, corresponding experimental and numerical studies on fuel dispersal are carried out.

12. Wish you will love and make progress everyday!

13. The temperature and fuel concentration on the surface decline by adding water in fuel and consequently prolong the ignition delay.

14. The lower the density of the charge is, the shorter the ignition delay.

15. The analysis of combustion parameters in cylinder shows that the ignition delay reduces, peak combustion pressure decreased and combustion process becomes more smooth.

16. The research indicated that the design modification had been utilized to solve the ignition delay, the ignition failure under low temperature etc ever occurred in the initial design completely.

17. Adding DMM in diesel fuel did less influence on the ignition delay and rapid burning duration while the total combustion duration would decrease with the increase of DMM in diesel fuel.

18. In conclusion, the influence of the control parameters to the ignition delay is increased with the increase of the octane number and the decrease of the cetane number of the fuel.

19. The results indicated that, though the amorce mass was the same, the ignition pressure, the ignition delay and opened manner of the nozzle closure were different.

20. In addition, the completed programming has been used to analysis the influence of main-depute powder proportion, ignition delay of depute power and plunger mass on interior performance.

21. The misfired and uncompleted burned cycles increase during the preliminary process and the ignition delay is longer than warm start during transient process, so the HC and CO emissions rise.

22. Physicochemical properties and combustion mechanism of boron are introduced. Long ignition delay time and low combustion efficiency are due to the properties of boron itself.

23. Using a combustion model some problems such as: the relationship between ignition delay and fuel concentration, the relationship between soot concentration and the equivalent ratio of mixt...

24. As for the effect of the percentage to laser diode ignition delay time, a completely different conclusion have been obtained when processing pressure has greatly changed.
