Effect of fuel injection parameters on the performance & emissions of biodiesel based CI engine-A review

Results in Engineering
The rapid depletion of petroleum reserves due to rising fuel consumption highlights the need for alternative energy sources. Research shows that biodiesel is a viable substitute for modern (combustion engine) CI engines, with properties like pure diesel.
