Abstract

The paper presents the experimental results evaluating the combustion
evolution of diesel (B0) and bio-diesel 10% (B10) fuel in the constant volume
combustion chamber (CVCC). With the advantage of the constant volume
combustion chamber (CVCC) with many transparent windows, it is easy to see
the inside of the combustion chamber and the ability to easily change
combustion parameters such as the air-fuel ratio, the ratio of excess gas,
pressure and temperature inside the combustion chamber, so the authors used
this combustion chamber for research. Fuel is injected with high pressure mixed
with the gas mixture before the ignition is turned on. The fire spread image of
the flame film was taken by Schlieren image setting method using CHONOS 1.4
high-speed camera (40000 frames/sec). The research results show that the rate
of flame spread, the rate of increase in pressure during the priming phase of
conventional diesel fuel is much higher than bio- diesel 10% (B10) fuel and the
delay time is shorter than bio-diesel 10% (B10) fuel.
