Performance Enhancement and Emissions Analysis of Diesel Engine with Biodiesel, N-Propanol and 1-Butanol Blend

An experimental investigation is conducted to evaluate the effects of using blends of 1-Butanol, n-Propanol and biodiesel with base diesel fuel, with 5% and 10% (by vol.) each alcohol fuel (1-Butanol and n-Propanol), on the diesel engine performance and exhaust gas emissions. The experimental investigation of the above fuel blends, with the engine working at different loads. Engine performance and exhaust gas emissions such as nitrogen oxides, carbon monoxide, carbon dioxide, unburned hydrocarbons and smokiness are measured. The measured results of alcohol fuel blends with different concentration compared with base diesel fuel results. It is revealed that this fuel, which can be produced from alcohol fuel blend with biodiesel and base diesel blends, is very promising biodiesel performance enhancement of diesel engine operations. The present work proved that the 5% of alcohol fuel blend with 25% of biodiesel and diesel produced maximum efficiency and minimize the exhaust emission level compare with 10% of alcohol blend and base diesel.
