ABSTRACT
Diesel fuel additives are chemicals which are added to the vehicles fuel to improve
engine performance, combustion properties, and emission characteristics. In this
paper, the experimental investigations of the effect of diesel-biodiesel-acetone
emulsion fuels on the performance and emissions of a direct injection diesel engine
have been reported. The tests were conducted on one-cylinder naturally aspirated
compression ignition engine operated at 1600 rpm. Measured characteristics were
torque, power, brake thermal efficiency, specific fuel consumption, exhaust gas
temperature, and exhaust gases of CO, CO2, unburned hydrocarbons (UHC), NO,
and O2.The obtained results show that the torque, power, and Break Thermal Energy
were increased when we compare the engine operation with pure diesel fuel.
Additionally, the specific fuel consumption and engine exhaust gas temperature were
reduced. The CO, UHC, and soot emissions were decreased. However, the NO
emission was increased.
