TL;DR: In this article, the authors investigated the influence of biodiesel on the performance and emissions of medium power agricultural tractor engines (37-66 kW) and found that biodiesel reduced the content of CO2 and CO, as well as the temperature of exhaust gases, but it increased the emission of NOx.

TL;DR: In this article, the influence of different alcohols and reaction conditions on biodiesel yield was investigated using linear multiple regression models, which revealed that transesterification in supercritical methanol has the lowest direct material and energy costs.

TL;DR: In this article, the influence of the process parameters for the industrially relevant reaction of free fatty acid (FFA) with glycerol is investigated and several drying techniques are investigated and a novel method is suggested that can provide more realistic experimental conditions.

TL;DR: In this paper, the authors demonstrate the dependence of wheeled tractor power delivery efficiency on wheel slippage for central and oblique drawbar forces, both on plowed and unplowed stubble.

TL;DR: In this paper, a comprehensive review explores the potentials of the available conventional biodiesel sources (oilseed crops), as well as the next generation biodies sources, including waste cooking oil and oil from non-edible agro-food wastes that were previously reported as potential biodiesel feedstock in Europe.
