Effects of injection parameters on performance of diesel engine run on biodiesel from direct transesterification / Tatagar Mohammad Yunus Khan

It is well-known that energy consumption is rapidly increasing due to the population growth, higher standard of living and increased production. Significant amount of energy resources are being consumed by the transportation sector leading to the fast depletion of fossil fuels and environmental poll...
