Smart choice transesterification-base-produced biodiesels and their performance characteristics in diesel engine

Abstract

The present study experimentally examines the performance of a diesel engine with biodiesel blends. Different biodiesels are produced through transesterification and mixed with conventional diesel fuel. Vegetable oils are selected because of the availability of the feedstock and their price. The range of representative measures of performance and engine emission characteristics are analyzed. It is proved that increasing the biodiesel concentration inside the blends would improve the brake power brake specific fuel consumption (BSFC) while increasing smoke production, and CO and ${CO}_2$ emissions as well. An artificial neural network (ANN)-based sensitivity analysis is also implemented to evaluate the role of different parameters toward variability of performance and emission characteristics.
