- Abstract
In this study, the effects of ethanol and unleaded gasoline with Isoheptanol blends on multi- cylinder SI engine were investigated. The test fuels were prepared using 99.9% pure ethanol and unleaded gasoline with Isoheptanol blend, in the ratio of E 60 + 2.0 Isoheptanol, E 50 + 1.0 Isoheptanol. In this work the performance, emission and combustion tests were conducted in multi-cylinder petrol engine. The experimental results reveal an increase in brake thermal efficiency on the use of test fuel. In the emission test, CO is found slightly decreased, while HC increased moderately and CO2 and NOx are appreciably reduced, when compared to the sole fuel. The second part of the investigation is carried out in the same engine with Alumina Titania coated crown of the pistons, to gain more inside improvement of engine performance and in-cylinder pressure for coated pistons. The experiment is repeated along with fuel additives and ethanol blends in the same blended ratio to analyse the performance and combustion characteristics of the engine. The results show marginal increase in brake thermal efficiency and reduction in CO, NOx, HC and CO2 emissions. In this study, combustion analyses are made with the help of AVL combustion analyzer, in which cylinder pressure, heat release rate and cumulative heat release are performed.
