Experimental Study of Pulsed Jets of Aviation Kerosene Formed by the Air-Assisted Injection System of an Internal Combustion Engine

The characteristics of aviation kerosene pulsed jets atomization formed by a high-pressure air-assisted injection system are investigated. A configuration with a high-pressure channel elongated to 500 mm is being considered, which is determined by the design requirements. The influence of the elongated channel on the dispersed composition and the cycle-to-cycle variability of the characteristics of pulsed jets is analyzed. It is shown that the air-assisted injection system provides the high-quality spraying with acceptable cycle-to-cycle variability.
