RESUMO

Spray of fuel containing CO2 is a method of twin-fluid spray that involves dissolving CO2 gas into liquid fuel before it is ejected from the injector. The technique of dissolving CO2 gas into liquid fuel is essentially different from other methods of twin-fluid spray and leads to significant improvements in performance in terms of smaller drop sizes and lower injection pressures. This paper presents an experimental study on the process of injecting a bubble jet of transient spray with fuel containing CO2 using high-speed imaging technology. Experiments were performed under atmospheric conditions with a diesel hole-type nozzle. The effect of injection pressure on the bubble jet atomization process was evaluated, especially in the early stage of injection. The transient characteristics of spray, such as spray angle and spray tip penetration, were also investigated. The images clearly display the developing process of the spray. New insight into the process of bubble jet injection of fuel containing CO2 spray was obtained, and a possible mechanism to explain the phenomena was proposed.
