Abstract
This work aimed to compare the performance and emissions of different test fuels in a compression ignition engine. The fuels included diesel, SFEEE20, and SFME20, with and without a diesel reforming and partial oxidation system. Syngas and pyrolytic oil produced from Safflower were used in single and dual fuel modes. The results showed that brake thermal efficiency (BTE) increased in dual fuel mode compared to single fuel mode. Diesel with SFS exhibited the highest efficiency of 32.20%, followed by SFEEE20 with SFS at 31.91% and SFME20 with SFS at 31.08%. The specific fuel consumption (SFC) decreased in dual fuel, and at maximum load condition, SFME20 with SFS demonstrated the lowest SFC of 0.3193 kg/kW-hr in dual fuel mode. SFEEE20 with and without SFS displayed SFC values of 0.28051 and 0.3005 kg/kW-hr, respectively. At maximum load condition, SFME20 with SFS exhibited an EGT of 187°C, while PME and diesel with SFS showed EGT values of 183°C and 184°C, respectively. CO and HC emissions decreased in dual fuel mode compared to single fuel mode. The work concluded that SFEEE20 with SFS showed promising results with high BTE and low emissions, making it a potential fuel blend for compression ignition engines.
