【 摘 要 】

Acid oil which is extracted from vegetable oil refinery operation where acid oil is cheap and readily available in enormous quantities. Acid oil consists of less amount of mineral acids (2-3%) along with long chain free fatty acid mixture, phospholipids and free moisture (4-9%) thus makes the acid oil to dark brown in colour. In this paper, the main concentration is on emission, performance and combustion characteristics using diesel and acid oil methyl ester as fuel for single cylinder diesel engine. To estimate brake thermal efficiency, HC and CO emission and combustion duration, test was conducted at different injection timings of 190,230,270 and 310 BTDC, keeping constant injection pressure at 205 bar and rated speed of 1500 rev/min. For each and every load, fuel flow rate, air flow rate, exhaust gas temperature, CO2, CO, HC, NOX and smoke emissions were recorded. Based on the readings with the specified condition, optimum injection timing was recorded for each of the fuel tested.
