An experimental study on the performance and emission characteristics of a single-cylinder diesel engine running on biodiesel made from palm oil and antioxidant additive

Abstract

The current experiment will look into the effect of adding an antioxidant (butylated hydroxytoluene) to palm oil biodiesel (20% palm oil + 80% diesel) in a diesel engine to reduce exhaust emissions. Alkali transesterification of palm oil produces biodiesel. Different biodiesel blends are generated for fuel samples, including 95 percent biodiesel plus 5 percent butylated hydroxytoluene (P20BHT5) and 90 percent biodiesel plus 10 percent butylated hydroxytoluene (P20BHT10). According to the experimental examination, P20BHT5 and P20BHT10 emit much fewer oxides of nitrogen than P20 and diesel fuel. Additionally, the brake thermal efficiency (BTE) is considerably lower as compared to P20 when an antioxidant ingredient is added to the biodiesel in the engine. Also found was a modest increase in smoke, carbon monoxide, and hydrocarbon emissions when an antioxidant ingredient was added to P20.
