In present experimental investigation 3.75 kW diesel
engine AV1 Single Cylinder water cooled, Kirloskar Make
tested for blends of diesel with ethanol. Tests were conducted
for three different compression ratios. Engine test setup was
developed with moving cylinder head for variation of
compression ratio to perform investigations using these blends.
The engine performance studies were conducted with rope
break dynamometer setup. Parameters like speed of engine,
fuel consumption and torque were measured at different loads
for pure diesel and for blends of diesel with ethanol at different
compression ratio. Break Power, BSFC, BTE and heat balance
were evaluated. Paper represents the test results for blends 5%
to 20% and three different compression ratios.
