Biofuels represent a group of emerging alternative fuels for current automobiles and aircraft engines. Soy methyl ester (SME) and Canola methyl ester (CME) are two such biofuels and are formed by the transesterification of soy oil and canola oil respectively. SME and CME, like other biofuels, are environmentally carbon-neutral, have no sulfur content, are locally produced and have diesel-like properties. The objective of this study was to characterize the combustion properties of spray flames of blends of SME and CME with No. 2 diesel fuel in a heated, co-flow air environment. The experiments were conducted maintaining fuel lean conditions at two different global equivalence ratios for each of the blends tested. Six different blends of SME and CME were studied. A partial swirl, air blast atomizer was used to create the spray. The global emissions from the flames were measured by collecting samples in the exhaust and passing the sample through a gas analyzer. Similarly, the in-flame species concentrations of CO, NO, CO2 and O2 were measure. In-flame temperature measurements were performed using an R-Type thermocouple and were corrected by radiation, convection and conduction.

Abstract : A multicomponent vaporization model is integrated with detailed fuel chemistry and soot models for simulating biodiesel–diesel spray combustion. Biodiesel, a fuel mixture comprised of fatty-acid methyl esters, is an attractive alternative to diesel fuel for use in compression-ignition engines. Accurately modelling of the spray, vaporization, and combustion of the fuel mixture is critical to predicting engine performance using biodiesel. In this study, a discrete-component vaporization model was developed to simulate the vaporization of biodiesel drops. The model can predict differences in the vaporization rates of different fuel components. The model was validated by use of experimental data of the measured biodiesel drop size history and spray penetration data obtained from a constant-volume chamber. Gas phase chemical reactions were simulated using a detailed reaction mechanism that also includes PAH reactions leading to the production of soot precursors. A phenomenological multi-step soot model was utilized to predict soot emissions from biodiesel–diesel combustion. The soot model considered various steps of soot formation and destruction, such as soot inception, surface growth, coagulation, and PAH condensation, as well as oxidation by oxygen and hydroxyl-containing molecules. The overall numerical model was validated with experimental data on flame structure and soot distributions obtained from a constant-volume chamber. The model was also applied to predict combustion, soot and NOx emissions from a diesel engine using different biodiesel–diesel blends. The engine simulation results were further analysed to determine the soot emissions characteristics by use of biodiesel–diesel fuels.

With a focus on ecology, economy and engine performance, diesel engines are explored in relation to current research and developments. The prevalent trends in this development are outlined with particular focus on the most frequently used alternative fuels in diesel engines; the properties of various type of biodiesel and the concurrent improvement of diesel engine characteristics using numeric optimization alongside current investigation and research work in the field. Following of a short overview of engine control, aftertreatment and alternative fuels, Green Diesel Engine explores the effects of biodiesel usage on injection, fuel spray, combustion, and tribology characteristics, and engine performance. Additionally, optimization procedures of diesel engine characteristics are discussed using practical examples and each topic is corroborated and supported by current research and detailed illustrations. This thorough discussion provides a solid foundation in the current research but also a starting point for fresh ideas for engineers involved in developing/adjusting diesel engines for usage of alternative fuels, researchers in renewable energy, as well as to engineers, advanced undergraduates, and postgraduates.
