Abstract
An experimental study on a direct-injection gasoline spray initiated from a swirl injector was carried out in order to clarify the effects of ambient temperature and pressure. The sprays were formed in a pressure chamber where the maximum pressure and temperature reached 1.1 MPa and 423 K respectively. The spray-tip penetration for elevated ambient temperature is slightly longer than that for normal ambient temperature. From the measurement using phase Doppler anemometry, it was found that the Sauter mean diameter D32 is large under high ambient pressure condition. The effect of elevating the ambient temperature is to decrease D32 in the core region of the spray.
