Experiments were conducted on this at constant RPM with corn biodiesel (Corn Methyl Ester-CME), Petroleum Diesel (PD), B20 (20% CME+80%PD), B40 (40% CME+60%PD). The performance parameters like Brake specific fuel consumption (BSFC), Brake thermal efficiency (BTE), Brake specific energy consumption (BSEC), and Indicated mean effective pressure (IMEP) were evaluated at different engine loads. The cylinder pressure variation, heat release rate and mass fraction of fuel burnt were also studied. Emission characteristics like CO, HC and NO x were also investigated and compared all with diesel fuel values. From the test results it was observed that all the characteristics of the engine with CME and its blends are very closer to characteristics of engine with baseline petroleum diesel. BTE,EGT, IMEP decreased and BSFC,BSEC increased with increase in percentage of CME in blend. CO,HC emissions were reduced and NO x was increased with CME.

Transesterified fat oil (biodiesel) are promising alternative fuel for diesel engines. The objective of this research is to study the performance and emission characteristics of single cylinder diesel engine fueled with chicken fat biodiesel with the influence of fuel injection pressure. Bio diesel was produced from waste chicken fat by transesterification process and used as fuel in diesel engine.

All the results obtained with CFBD fuel were comparable with diesel and also CFBD fuel satisfies all the requirements as per standards. Hence the CFBD fuel can be used in existing diesel engine without any engine modification.
