Abstract

Usage of bioethanol as a oxygenate fuel in spark ignition engine have been an effect on reducing hydrocarbon emissions, even it can be minimize products of NOx emission if bioethanol applied in high concentration, as well as it have a significant impact on decreases greenhouse gas (GHG) effect. It's just that the generated power is lower than gasoline, so the suitable on bioethanol injection is required to get the equivalent power with gasoline. Grade octane of bioethanol is higher than gasoline, so the high compression ratio can be employed to increasing the torque and power as a compensation in low of heating value of bioethanol. Re- adjustment on ignition timing is needed during the injection duration and compression ratio is changed so that the high engine performance and low emissions can be reached. This study will exploit the compression ratio at 12:1, 12.5:1 and 13:1 with the injection duration by 100%, 125%, 150%, 175% and 200% that based on injection standard at 24cc/s as well as the ignition timing is advanced at 10o, 14o, 18o, 22o and 26o BTDC, while standard spark timing of engine is 7o BTDC. Usage of pure bioethanol at the maximum compression ratio (13:1) have been resulting brake torque, brake power and BMEP is increases by 16.1%, 18.10% and 18.12%, while the CO and HC emissions were decreases by 75.5% and 17.24% in average respectively compared with gasoline. Nevertheless, the specific fuel consumption is increased by 115.8% at 2000-4000 rpm, 57.2% at 5000-6000 rpm and 23.5% at 7000-8000 rpm in average respectively.
