This paper investigated spray characteristics of rapeseed oil (RSO) as renewable fuel for common-rail (OR.) diesel engines using high-speed camera image technique and Phase Doppler Anemometry (PDA). Experimental spray penetration at various injection pressures and fuel temperatures for RSO were compared with data of standard oil (SO) taken at the same varying ambient conditions. Additionally. corresponding to penetration data, data sets of spray development for these two oils were also aquired. It has been found that RSO temperature of 60 graduate C being used in practice to preheat plant oils in modified OR, engines does not improve spray penetration to be sufficient to reach the penetration equivalent at 25 graduate C for SO. It is concluded that producing RSO spray similar to SO one recquires high injection pressure and fuel temperature, and the pressure effect is more influential. The PDA measurements revealed stronger injection pressure effect on values of Ds2 and DID than oil temperature.
