Effects of methanol blending on combustion characteristics and various emissions of a diesel engine fueled with soybean biodiesel

Effects of Different Biodiesel-Diesel Blend Fuel on Combustion and Emission Characteristics of a Diesel Engine

“…In order to solve the above problem, many researchers are also looking for clean energy sources such as solar, wind, and biomass to meet future economic development [7]. Because wind energy and solar energy are greatly affected by the natural environment, it is difficult to widely replace petrochemical fuels in a short time [8]. However, the biodiesel produced by animal and vegetable oil in ester exchange reactions, not only has the equivalent petroleum diesel combustion, but also has environmentally-friendly, renewable [9], and other positive features, making it one of the ideal diesel fuels to substitute petroleum [10].…”

Combustion Characteristics and Emission Analysis of Tetrahydrofuran–Biodiesel-Blended Fuel in a Diesel Engine

“…The torque output of the engine was controlled by an eddy current dynamometer. The fuel injection quantity and injection timing of the engine were adjusted by the electronic control unit. , The detailed structure and principle of the test bench are shown in Figure .…”

“…The exhaust smoke was measured by an opacimeter with an accuracy of 0.01 1/m. Unregulated emissions were tested by the FL9707 gas chromatograph with an accuracy of 0.01 ppm. , …”

“…It can be made from various animal fats or vegetable oils. , Biodiesel from different raw materials will have certain differences in various aspects of performance. , At present, biodiesel has experienced four generations, and factors such as raw material output, energy content, easy availability, economy, and carbon emissions are the consideration indicators for its update. The transesterification reaction has become the best method to produce biodiesel because of its high yield and better economy. , Combustion of pure biodiesel can reduce the emissions of various incomplete combustion products, but at the same time, it will increase emissions such as NO X . − This defect can be resolved by blending biodiesel with other fuels (such as gasoline, hydrogen, natural gas, biogas, and alcohol). − …”

Crystallization of hydrogenated biodiesel–ethanol–diesel blend based on the solid–liquid equilibrium theory

“…Rapeseed, soybean, cottonseed, palm, and safflower oils 4 have been shown as crucial feedstocks when the current potential feedstocks for biodiesel production around the world are evaluated. Out of several biodiesels from vegetable oil, the biodiesel produced from soybean and cottonseed oils 5,6 are attracted by researchers. The economic value and favorable physicochemical properties are the main reasons to choose it as an alternative fuel for the diesel engines.…”
