In the present work, spray characteristics of Lemon Peel Oil (LPO) were studied to check its suitability in the direct injection spark ignition engine. From the fuel properties, it was observed that LPO has superior calorific value and comparable octane rating compared to the conventional biofuels, i.e., alcohols. Experiments were performed in a constant volume spray chamber under different engine like pressure and temperature conditions. A six-hole GDI injector was used to study the spray behavior of LPO and then compared to standard reference fuel, isooctane. The ambient conditions in the chamber were derived using the crank resolved pressure data of the GDI engine. The selected chamber conditions are a) 1.5 bar, 329 K; b) 2.5 bar, 371 K; c) 6.0 bar, 453 K. Three parameters,i.e., liquid penetration length, spray cone angle, and droplet distribution was studied to understand fuel spray behavior. Mie-scattering technique was used to determine liquidpenetration,and cone angle the droplet size distribution was measured using the Phase Doppler Particle Analyzer (PDPA).Results showed that ambient pressure and temperature have a significant effect on spray behavior for both the selected fuels. The spray penetrationwas decreasedwith an increasein pressureand temperature. Both LPO and isooctane showed better droplet evaporation at higher pressure and temperature conditions.
