Spark ignition engine is preferred locomotive prime mover due to its smooth operation and low maintenance. The petrol is fossil fuel which is limited in reservoirs causes varieties of study in search of alternative fuel for SI engine, where alcohol promises best alternative fuel. In this paper, performance and emission analysis of a SI engine using the ROEE-Petrol Blend and Petrol were carried out. In this novel, it has been found that the addition of fuel has increased the performance characteristics (Mechanical efficiency), decreased SFC along with considerable reduction in emissions from the optically accessible engine as the test rig with optimum power production. Experiments were carried with variable speed constant load and constant speed variable load methods.
