Hydrotreated Vegetable Oil (HVO) and Gas to Liquid fuel (GTL) are two renewable fuels without shortcoming as traditional renewable fuels such as FAME. This project aims to research macroscopic spray characteristics of HVO and GTL during both injection and post-injection periods at high ambient temperature and pressure. The work is conducted by experiments on a constant volume vessel (CVV) system at 1800 bar rail pressure, 10 bar and 40 bar ambient pressure and 600 K ambient temperature. Results indicate that HVO and GTL have similar average cone angle to standard diesel fuel (DF), whilst their spray tip penetration during injection and post-injection periods are both smaller than that of DF. Moreover, the two renewable fuels have faster evaporation at high ambient temperature compared with DF, and thus results in the reduction of spray tip penetration with sample time.
