Fig. 13.7 Comparison of brake thermal efficiency for biodiesel-diesel-alcohol fuel at different
nozzle opening pressure and fuel injection timing at full load condition (A) NOP 200bar,
(B) NOP 300bar, (C) NOP 400bar, (D) NOP 500bar, and (E) NOP 600bar.

FIT from 19 to 27°CA bTDC for all tested fuels. With a further increase of the NOP
above 600bar, the engine BTE was not improved. From the experimental results, the
maximum BTE of 29.46% at 200bar and 27°CA bTDC, 31.47% at 300bar and 27°CA
bTDC, 33.34% at 400bar and 27°CA bTDC, 35.39% at 500bar and 25°CA bTDC, and
34.79% at 600bar and 25°CA bTDC was obtained for B90-D5-H5 blend. Diesel has
