Biodiesel has been a promising alternative clean fuel to fossil fuels,
which reduces the emissions that are released by fossil fuels and
possibly reduce the energy crisis caused by the exhaustion of petroleum
resources in the near future. Biodiesel is replacing diesel as an
alternative fuel for internal combustion engines. In this study
biodiesel blend B20 and ULSD (B0) were combusted to investigate how the
engine conditions influence the emission concentrations of H2, CO, CH4,
CO2, N2 and morphological data of particulate matter. From our results
under varied tested conditions we have incurred that, for low H2
emissions, B20 combustion under low temperatures and high pressures is
preferred. For low CO emissions, B20 combustion under high temperatures
and pressures is preferred. For low N2 emissions, ULSD combustion under
low temperatures and high pressures is preferred. For low CH4 emissions,
ULSD combustion under low temperatures and high pressures is preferred.
For low CO2 emissions, ULSD combustion under low temperatures and low
pressures is preferred.
