Depending on the heat content and compression ignition
(CI) engine
combustion, biodiesel is a viable substitute fuel. Biodiesel is an
oxygenated, safe, sulfur-free, biodegradable, and renewable fuel.
It may be utilized in CI engines in any combination with diesel fuel
without requiring the engine to be significantly modified. Many research
studies have been made with several biodiesels as diesel substitutes,
including Pongamia pinnata, Jatropha curcas, Mangifera indica, and Madhuca longifolia. The topic of the current review is the potential of renewable fuels
to outperform diesel fuel in terms of performance, combustion, and
emission characteristics. In the present study, CI engines are fueled
with biodiesels made from Man. indica, Mad.
longifolia, and pongamia seed oil. Adopting low heat rejection
(LHR) mode CI engines and adding an antioxidant agent in addition
to the biodiesel blends may resolve the issue of these biodiesels’
poorer performance and increased NO emission. Both these additions
may provide positive approaches in both performance and emission.
