Experimental Analysis on Performance, Emission and Vibration Characteristics of a Biodiesel CI Engine fueled with Diesel-Methanol blend

Abstract

In This Thesis, An Experimental Analysis Of Diesel/Methanol Engine Performance, Emissions, And Vibration Characteristics Using Ratio Blends Of B10, B20, B25, And B30 At Various Engine Load Conditions Is Presented. According To The Performance Analysis, The Addition Of Methanol Resulted In A Minor Drop In Brake Power, Which Was Mostly Caused By Methanol's Lower Energy Content Than Diesel. The Power Of Blended Fuels (D90m10), (D80m20), And (D70m30) Was Lower Than That Of Pure Diesel By 2.76%, 5.04%, And 8.08%, Respectively. On The Other Hand, When The Amount Of Methanol Increased, Thermal Efficiency Improved By 0.031% To 0.056% As Methanol Concentration Is Increasing, Suggesting Better Fuel Economy And Increased Combustion Efficiency. The Experimental Analysis Showed That, Especially At Lower Engine Loads, Methanol Blending Significantly Reduced Emissions Of Hydrocarbons (Hc) And Carbon Monoxide (Co). Particulate Matter (Pm) Emissions Also Showed A Declining Trend With Increasing Methanol Content, Indicating The Potential For Cleaner Combustion And Less Environmental Impact. Nitrogen Oxide(Nox) Emissions Showed Only Slight Increment Variations Across Different Loads. The Addition Of Methanol Affected Engine Vibrations, According To Vibration Analysis, With The Effects Becoming More Noticeable At Higher Engine Loads. The Fact That The Vibrations Were Still Within Tolerable Bounds For Engine Operation Highlights The Significance Of Carefully Adjusting And Optimizing Engine Settings In Order To Reduce Any Potential Unfavorable Effects. All Things Considered, The Results Of This Experimental Investigation Offer Insightful Information About How A Diesel/Methanol Engine Behaves Under Various Blend Ratios And Engine Load Scenarios. The Findings Show That Brake Power And Thermal Efficiency Must Be Traded Off For Better Fuel Economy And Lower Emissions Of Pm, Hc, And Co. The Continued Efforts To Provide Internal Combustion Engine Fuel Alternatives That Are More Sustainable And Cleaner Are Aided By These Findings. The Research's Conclusions Have An Impact On The Energy And Transportation Industries, Opening The Door To A Future That Is Greener And More Ecologically Friendly.
