Abstract
Ethanol has become a promising alternative fuel for spark ignition engines due to its smaller carbon footprint and potential to reduce harmful emissions. In this study, using the Diesel RK software, a technical analysis of the use of ethanol in a spark ignition engine originally designed to run on gas was performed. The effects of different ethanol blends (E96, E90, E80 and E70) on OC13 101 engine performance, fuel consumption and exhaust emissions were evaluated. The results obtained showed that the use of the ethanol-water mixture as fuel in the engine led to a reduction in emissions and consumption. The greatest reductions were observed when using E70, reduction in nitrogen oxide (NOx) emissions. It was found that engine power and torque decreased slightly with the use of higher ethanol blends. Fuel consumption also increased slightly with higher ethanol blends. The results indicate that the use of ethanol in spark ignition engines is a promising approach to reduce harmful emissions, but its effects on engine performance and fuel consumption must be taken into account. In general, the technical analysis of the engine behavior revealed that the use of ethanol-water mixtures can be a promising fuel alternative. The findings of this study will provide valuable information for the development of alternative fuel technologies and their implementation in the transportation sector.
