Experimental Study On Performance, Emission And Vibration Characteristics Of Ethanol-Gasoline Fueled Spark Ignition Engine

Abstract

The Importance Of Alternative Fuels For Both Compression And Spark Ignition Engines Has Increased Due To Growing Environmental Concerns And The Need To Lessen Dependency On Petroleum. This Research Report Details An Extensive Investigation Into The Effects Of Gasoline And Ethanol-Fueled Spark Ignition Engines On Engine Vibration, Emissions, And Performance. Based On The Experiment, It Can Be Concluded That Gasoline And Ethanol Blends Perform Well And Help Reduce Emissions. Fuel Blends E0 (100% Gasoline), E5 (5%Ethanol And 95% Gasoline), E10 (10% Ethanol And 90% Gasoline), E15 (15% Ethanol And85% Gasoline),E20(20% Ethanol And 80% Gasoline) And E25(25% Ethanol And 75%Gasoline) Are Used In The Experimental Design. The Test Engine Was The Tbmc3 Gasoline Engine, Which Was Kept At The A Astu Automotive Engineering Workshop. For All Fuel Types, The Test Is Run At Various Engine Load Conditions (10 Kg, 15 Kg, 30 Kg, 45 Kg, 60 Kg, And 75Kg) And At Constant Engine Speed Of 1750rpm. The Engine Dynamo Meter Is Used To Measure Power And Torque, The Exhaust Gas Analyzer Is Used To Measure Emissions, And The Vibxpert Ii Instrument Is Used To Measure Engine Vibrations. A Comprehensive Analysis Is Carried Out Following The Data Collection Phase To Derive Significant Insights Into The Impact Of Gasoline-Ethanol Blends On The Performance, Emissions, And Vibration Characteristics Of Spark Ignition Engines. According To The Experimental Findings, The Range Of Co And Hc Emission Reductions For All Test Fuels Is 14.79% To 49.1% And 11.99% To53.57%, Respectively. The Range Of Increases In Nox Emissions Is 16.23% To 48.74%.Engine Power And Torque Rise By A Range Of 4.5% To 41%, And 3% To 45% Respectively. Bsfc Exhibits A 6.95% To 26% Reduction In Comparison To Pure Gasoline. There Is A Rise In Engine Vibrations From 6.5% To 25.3%.Every Test Fuel's Engine Vibration Is Evaluated Using International Standard Organization Guidelines. The Engine Vibrations Of The E0, E5,E10, And E15 Do Not Affect This Particular Engine Type. When The Test Engine Was Running On E25 Fuel, Its Vibration Did Not Affect It At Low Load, But At High Load, It Caused Issues That Made It Unsatisfactory To Operate For Extended Periods.
