Studies on the effect of ethanol addition to biodiesel: Performance and emissions of a diesel engine.


The interest on alternative fuels is continuously increasing to meet the growing energy needs and protect the environment. Ethanol and biodiesel are two potential and promising alternative fuels for internal combustion engines. Ethanol can be used with biodiesel fuel to extent the availability of diesel. In this work, experimental investigations were carried on a single cylinder diesel engine using B25, B50, B75 and B100 biodiesel diesel blends with 5% and 10% ethanol addition. The engine performance and emission characteristics were investigated. The thermal efficiency, NOX and smoke emissions were found experimentally. The addition of ethanol to biodiesel diesel blends did not alter the engine performance significantly. The engine produced lower NOX and smoke emission with ethanol addition.
