Experimental Analysis of Spark Ignition Engine on Exhaust Gas Temperature and Deposit Formation using Alcohol Blend Fuels

Abstract

Using gasoline engines with alcohol is another method to lessen reliance on fuel.   Gasoline can be mixed directly with higher alcohols, like ethanol (E), which are generally derived from non-edible sources and have a high carbon content.   Among the issues faced by consumers of fossil fuels include price volatility, supply constraints, environmental damage, increasing demand over time, and greenhouse gas emissions contributing to climate change.    Similar effects are seen with gasoline fuel, albeit with distinct issues.  Research indicates that the addition of alcohols to gasoline fuel alters its properties.  An air-cooled single-cylinder spark ignition engine's exhaust gas temperature characteristics were examined in this work by adding E10 and E20 with ethanol percentages to pure gasoline. A 4-stroke, single-cylinder petrol engine operating at a steady 1350 rpm was used in our tests. With the same working braking power, temperatures of 270 ^oC, 274 ^oC, and 288 ^oC were recorded in the case of G80E20 with a 20% ethanol dosage. Compared to G100 and G90E10, the exhaust gas temperature (EGT) decreased for G80E20 when ethanol concentration was added. These findings imply that there is no need for modifications while using the high concentration blend G80E20 and the low concentration mix G90E10 in gasoline engines.
