This paper presents studies of spray characteristics and controlling mechanism of fuel containing CO 2. Using diesel fuel containing CO 2 gas, experiments were conducted on diesel hole-type nozzles and simple nozzles. The steady spray and transient spray characteristics were observed and measured by instantaneous shadowgraphy, high-speed photography, phase Doppler anemometry (PDA) and LDSA respectively. The effects of CO 2 concentration in the fuel, the injection pressure, the nozzle L/D ratio, surrounding gas pressure and temperature on the atomization behavior and spray pattern were evaluated. The results show that the injection of fuel containing CO 2 can greatly improve the atomization and produce a parabolic-shaped spray; and the CO 2 gas concentration, surrounding gas pressure, temperature and nozzle configuration have dominant influences on spray characteristics of the fuel containing CO 2. New insight into the controlling mechanism of atomization of the fuel containing CO 2 was provided.
