Abstract
This paper presents experimental results carried out to evaluate performance and exhaust emissions characteristics of a turbocharged diesel engine when operated on anti-corrosion additive blended palm oil methyl ester. The palm oil methyl ester is also called biodiesel. A total of eight fuels were used including ordinary diesel fuel (OD) which was used for comparison purposes. The performance results such as brake power and specific fuel consumption (SFC) were measured using computer controlled eddy current dynamometer and load cell arrangement respectively. The emissions results such as CO, CO2, NOx and HC were measured using Bosch and Bacharach exhaust analyzers. The results show that anti-corrosion additive is effective to enhance turbocharged engine brake power and to reduce exhaust emissions including NOx emissions. From the overall test results, fuel B20+1% (20% biodiesel with 1% additive) were found as a promising alternative fuel for diesel engine.
