Abstract: The article deals with the effects of butanol-diesel fuel blends on performance and exhaust emissions of a turbocharged, CRDI 1154HP (85 kW) diesel engine. Load characteristics were taken when running with normal diesel fuel and n-butanol-diesel fuel blends DB1, DB2..DB3, and DB4 possessing lwt%, 2wt% 3wt%, and 4wt% of fuel-oxygen at speeds of 1800 and 2500 rpm. The auto-ignition delay increased by 15.5%, burn angle MBF 50 and the combustion ended 7.6% and 6.5% earlier in the cycle, bsfc and engine efficiency were 2.8% and 1.9% higher when using fuel blend DB4 than the respective values of 17.4°, 20.9° and 61.2° CADs, 234.4 g/kWh and 0.361 a fully loaded (100%) straight diesel develops at speed of2500 rpm. The NOx CO, THC emissions, and smoke decreased by 5.1%, 29.5%, 3.7 times, and 48.1% against the respective values of1020ppm, 563 ppm, 260ppm, and 12.9% a straight diesel develops under these test conditions
