Spray fuel through a single hole
Web1 Apr 2024 · In this study, high-speed liquid fuel jets from a single-hole GDI injector were studied. The nozzle diameter of the injector was 0.14 mm, and the nozzle length was 0.20 mm. The test parameters used in the study are tabulated in Table 1. N-heptane was used as the test fuel, and the commanded pulse width of the injector was constant at 1.5 ms. WebBosch donated five nominally identical single-hole injectors for “Spray A” research. All ambient and injector operating conditions for Spray A research are given in detail. The specifications for the injector and nozzle are as follows: Specifications for Spray A injectors of the Engine Combustion Network Common rail fuel injector Bosch solenoid-activated, …

WebThe double concentric swirl burner used here has a centrally located fuel nozzle surrounded by two annular passages through which combustion air is supplied to the burner. Airflow and swirl vane angle (swirl strength) can be varied independently in each annulus.
Sprays of hydrocarbon liquids (fossil fuels) are among the most economically significant applications of sprays. Examples include fuel injectors for gasoline and diesel engines, atomizers for jet engines (gas turbines), atomizers for injecting heavy fuel oil into combustion air in steam boiler injectors, and rocket engine injectors.
