Ignition Delay Period of Jojoba Diesel Engine Fuel 972975

Thermal ignition delay of the new fuel derived from Jojoba Seeds and its blends with diesel fuel and methanol has been measured. For this purpose, a shock-tube test set-up was designed and manufactured. It was instrumented for delay measurement with piezo-electric pressure transducers, charge amplifiers, storage oscilloscope and electronic plotter. The test variables included the type of fuel (Jojoba Methyl Ester and its blends with Gas oil and Methanol), equivalence ratio, ignition pressure and ignition temperature. The activation energy of the new fuel as well as its blends with Gas Oil and Methanol was evaluated through the use of Arrhenius plots. The results have shown that the Jojoba methyl ester has superior ignition characteristics to Gas oil and Methanol and the blend with them. The suitability of such promising fuels for diesel engines is highlighted. A correlation was developed to predict the effect of variables which read:
