Abstract

In the present work, exergy terms, irreversibilities, and the amounts of emissions in a two-stroke engine with alcoholic fuel additive have been investigated experimentally. The applied alcoholic additive is Ethanol which is combined with gasoline in different percentages of 5, 10, and 15 %. The experiments have been done for 2,500, 3,000, 3,500, and 4,500 (rpm). The results show that in most test cases where alcoholic fuel is used, the combustion internal irreversibility increases, which is due to the increase in temperature difference between burned combustion products and unburned mixture that occurs as a result of the rapid evaporation of the alcohol fuel additives. This is an important reason for second law efficiency reduction. But for the case of little additive percentage (5 %), it has a reverse effect which can be assumed as an advantage. The most outstanding result of using ethanol additive is that the production of pollutants such as HC, CO2, CO, and NO x has been significantly reduced in all test cases.
