This paper reports the findings on the performance and emission of a diesel generator using diesel-butanol-biodiesel was examined. The experimental results revealed that formaldehyde, acetaldehyde and acrolein account for more than 75% of aldehydes and ketones emissions. Different blends of diesel-biodiesel-butanol were used to appropriately examine the effects of fuel composition on engine-out emissions.  The biodiesel used in this study was derived from waste cooking oil. The reduction is largely evident for nitro oxides, particulate matters and carbon monoxide. On the other hand, increasing the amount of biodiesel in the blends lowers engine out emissions.  Amongst the fuel compositions studied, the blends with 70% diesel, 10% butanol and 20% biodiesel resulted in lowest emissions level.
