characteristics on four stroke single cylinder diesel engine
fueled with diesel RBOblends with Ethanol and EHN as
additives are summarized as follows.
1. Brake thermal efficiency increased with all blends
when compared to the conventional diesel fuel.
2. The Brake specific fuel consumption is decreased
with the blends when compared to diesel.
3. CO,CO2 and HC emissions are decreased
significantly with the blends when compared with
diesel.
From the above analysis the blend RBE35 shows the better
performance compared to other blends(RB25,RB35, RB45,
RBE25,RBE45) and diesel
