Abstract

The performance and exhaust emissions of a diesel engine using light oil, heated, rice-bran oil , heated rice-bran oil treated with ultrasonic wave, used frying oil, use frying oil treated with ultrasonic wave, used frying oil, used frying oil treated with ultrasonic wave, methyl esters of rice-bran oil and used frying oil have been compared. All the fuels performed satisfactorily in a precombustion chamber-type diesel engine without injection pump recalibration or any engine modification at the range of engine speed from 1600 to 2800 rpm at its full load during a sort period , with the rice-bran oil and rice-bran oil treated with ultrasonic wave requiring somewhat preheating when ambient temperature was below 15$^{\circ}C$. General performance and emission characteristics of light oil and bio-oils were comparable , with the bio-oil based fuels giving very low SO$_2$ and lower smoke readings.
