Performance and emission study of exhaust gas single cylinder diesel engine based on fuel bioethanol – high speed diesel (HSD) using fumigation and blending methods

Diesel engine exhaust gas contains a lot of particulates because it is influenced by factors from fuel which is not clean. The addition of ethanol to diesel fuel is expected to provide a solution to reduce exhaust emissions from diesel engines. The first step is fumigation method, process of mixing High Speed Diesel (HSD) and bioethanol directly in the combustion chamber of a diesel engine. The second method is compared with Blending method. HSD is mixed with bioethanol, there are 5 variation mixing. Variation 1 blending method diesel fuel (diesel), variation 2 (93% diesel, 2% surfactant and 5% ethanol), variation 3 (HSD 88%, 2% surfactant and ethanol 10 %), variation 4 (83% diesel fuel, 2% surfactant and 15% ethanol) and variation 5 Fumigation method (ethanol and diesel). This work were carried out at the Performance Engine Laboratory and Mechanical Engineering Manufacturing Laboratory in Engineering Faculty of Universitas Sultan Ageng Tirtayasa. The hypothesis of this research is that the mixture of ethanol and diesel fuel produces greater power and consumption compared to diesel fuel. Ethanol and diesel fuel mixtures can also reduce air pollution compared to diesel. Judging from the smoke density of each fuel. (paper)
