Effects of Biodiesel from Non Edible Oils on Engine Performance and Exhaust Emission: A Review
Keywords:
-Abstract
World energy demand is increasing continuously and due to the problems like limited reserves, high cost,
environmental pollution etc. related to fossil fuels, alternate energy sources are required like Biodiesel. Biodiesel is
cheaper, renewable, lesser pollutant than fossil diesel. Non edible oil biodiesel is cheaper than edible oil biodiesel also it
can neutralize edible oil market demand. In this paper the impact of non edible oil biodiesel on engine performance and
emission characteristics has been reviewed. Most of the authors in literature have reported that brake power and brake
thermal efficiency has decreased while brake specific fuel consumption has increased somewhat. On the other hand
emissions like CO, HC, CO2, smoke has decreased significantly while NOx emission has increased by some amount. In
the end, it was concluded that biodiesel can be used as an alternative to diesel without or with minor engine
modifications.
