Abstract
In a constant-volume combustion bomb at high temperature and pressure, the images of spray, ignition and combustion of various diesel/biodiesel blended fuels with different fraction were achieved by high-speed direct photography. Based on the images acquired, the effect of biodiesel addition on spray and combustion characteristics was analyzed. Results show that with increasing biodiesel blended in diesel fuel, spray cone angle decreases, and penetration of spray becomes greater than that of diesel fuel in the early stage but almost the same in the following stage. Compared with diesel fuel, ignition delay of biodiesel blends decreases and number of ignition position increases. The flame luminosity and distribution area decrease with biodiesel addition increasing.
