    Suggestion needed in selection of biofuel

    Hi CEans,
    I am going to do a project in Alternative fuels and especially in Biodiesel to use in Diesel engines.My guide had asked me to research on non edible oils that can be used as Biodiesel.
    As i search, I got mainly four oils that has very good to be used as biodiesel.They are
    1)Madhuca indica,
    2)Jatropha Curcas,
    3)Pongamia pinnata,
    4)Mellia azadiracta.
    I choose neem(i.e. Mellia azadiracta.). I want CEans view on this. Is it good to do it with neem oil?
    My friend is doing with cooking oil and I am doing with Neem oil.
    Please suggest details on feasibility, chemicals availability and benefits on this.

    I did investigate biodiesel a few years back. President Abdul Kalaam was also keen on Jatropha. I have been planting Jatropha since 1980. It is a plant that grows in semi arid zones without much fertilizers or care. It is a beautiful plant. The nut is called the psychic nut as eating the nut can cause hallucinations. Some wandering gypsies ate a bunch of the seeds from the hedge where we had planted it in Bangalore and were lying under the bushes in a stupor.

    However, in my opinion this may be the source of choice.

    There is one report against Jatropha saying that Kenya reports higher emissions from Jatropha fuel.

    A contrary report:

    Hi friends, I am happy to inform that I had finallt found my source.Its none other than Neem oil.
    Our project deals with the Extraction of Neem biodiesel using transesterification and testing its performance in a single cylinder diesel engine.

    Need suggestions.
    I saw some journals having graph for emission where it was plotted with CO vs Time.
    I want to know whether it is posdible to find it in this way or it can be found like load vs CO?

    Can you please post a link to the graph. Does not make sense to me. How can there be a variation of CO emission with time in a steady state situation?

    In an IC engine there could be variation between idling, steady running and acceleration/deceleration.
    While neem oil is a renewable resource, what will be the yield/hectare and cost?

    The X axis goes up to 1000 secs. Does this represent the ehaust of the IC engine or is this the exhaust of a steady state burning of the fuel in a burner?
    What do the percentages in the caption represent?
    CO2 and O2 becoming horizontal seems to be normal behaviour in a steady state situation. Drop in CO with time may be due to stabilization of combustion.
