Abstract: Kerosene (K)/diesel fuel (D)/honne oil (H) blends have a potential to improve the performance and emissions and to be alternatives to neat diesel fuel (ND) and has not been reported in the literature. Experiments have been conducted on DI diesel engine when fuelled with ND, H10 (10%H + 90%D, by volume) to H30, HK10 (10%H + 45%K + 45%D), HK20 (20%H + 40%K + 40%D) and HK30 (30%H + 35%K + 35%D). The emissions [CO, HC and smoke density (SD)] of fuel blend HK20 are found to be lowest, with CO and HC dropping significantly. The NOx level is higher with HK10 to HK30 compared to ND and H10 to H30. The brake thermal efficiency of HK10 to HK30 is almost the same and it is higher as compared to ND and H10 to H30. There is a good trade off between NOx and SD. Peak cylinder pressure and premixed combustion phase increases as kerosene content increases.
