  • The effects of using straight Jatropha oil on diesel engines - comments please?

    Hello all.

    Ive been asked to advise on the effects of using STRAIGHT Jatropha oil in diesel engines.

    Can anyone off any qualified opinions on this, whether they be negative or positive? or recommmend sources of information?

    More specifically, can anyone advise on

    - the frequency of the clogging of the injector
    - the frequency of replacement of the injector
    - other prone areas of the diesel engine that need to be taken care of?


    Thanks alot!

    Dave

    What are the specs of straight jatropha oil?

    Viscosity, lubricity, melting point, molecular weight. These are the specs that will affect the parameters you mentioned. Also, you don't state if this willbe used in conjunction with a heat exchanger (two-tank system), or a one-tank system.
    Cheers,

    Ben.

      Thanks Ben. Ill find the specs that you requested, hoopefully this will help you to answer my question fully. I'll get back to you on that....Thanks!

      Currently we are not using an oil heater, though we are in Cambodia, so the temperature is usually about 30c...

        OK, here are the specs.. hope this helps you in providing the best help.

        THANKS AGAIN!

        Kinematic viscosity at 40c = 35.4
        Kinematic viscosity at 100 = 7.93
        Density at 15c = 0.919
        Iodine number = 83g/100g
        Ash content = 5.8mg/100g
        Water and sediment = 0.05% (v/v)
        Acid value = 1.89 mgKOH/g
        Distillation = IBP>450c
        Flashpoint = 306
