Abstract: Hevea brasiliensis rubber seeds were collected and were extracted by using n-hexane as the solvent in the Soxhlet Extractor. The extracted semi drying oil was characterized by various physio-chemical and thermal properties. Fatty acid composition of the lipid was investigated using gas chromatography techniques. Vibrational studies of the oil show that the characteristic strong absorption at 1741 and 1644cm-1 for –C=O and –C=C– groups respectively. Both the 1H NMR and 13C NMR spectral studies indicate that the presences of triacylglycerol groups were saturated as well as unsaturated in nature. Photo pyroelectric technique (PPE) was used for thermal characterization of the extracted oil. The effect of the fuels on engine components and exhaust gas emissions such as total hydrocarbon, carbon monoxide, and smoke and brake specific fuel consumption were also investigated. Antimicrobial activity was compared with the standard control drug of chloramphenicol at a concentration of 10 μg/ml at 30, 37 and 42 oC
