| Summary: | The use of biomass based renewable fuel, n-butanol blends for compression ignition (CI)
engine has attracted wide attention due to its superior properties such as better miscibility,
higher energy content, and cetane number as compared to other alternatives fuel. In this
present study the use of n-butanol 10% blends (Bu10) with diesel fuel has been tested using
multi-cylinder, 4-stroke engine with common rail direct injection system to investigate the
combustion and emissions of the blended fuels. Based on the tested engine at
BMEP=3.5Bar. Based on the results Bu10 fuel indicates lower first and second peak pressure
by 5.4% and 2.4% for engine speed 1000rpm and 4.4% and 2.1% for engine speed 2500rpm
compared to diesel fuel respectively. Percentage reduction relative to diesel fuel at
engine speeds 1000rpm and 2500rpm for Bu10: Exhaust temperature was 7.5% and 5.2%
respectively; Nitrogen oxides (NOx) 73.4% and 11.3% respectively. |
