Opportunities and challenges for the application of biodiesel as automotive fuel in the 21st century

Abstract: Depletion of fossil fuel and massive emissions of hazardous greenhouse gases are prompting many researchers to focus on greener renewable fuel such as biodiesel, which has the potential to replace petrodiesel partially. This review covers various aspects related to biodiesel feedstock and its effects on biodiesel characteristics, biodiesel production methods, blending techniques, biodiesel properties, combustion, engine performance, and emission analysis, the effects of different additives on biodiesel charact… Show more

“…Indeed, environmental contamination has led to intense research on alternative energy sources 1 . In this context, biofuels such as biodiesel (BD), 2 alcohols 3 and vegetable oils (VOs) 4 are utilized in a variety of applications to replace a portion of fossil fuel usage. Other liquid, gaseous and solid biofuels, as well as innovative processes, are interesting options.…”

“…The alarming rate of climate change in combination with the diminishing of petroleum reserves have spurred to the urgent need to develop sustainable alternative fuels suitable for replacing fossil fuels. Although biodiesel (FAMEs) produced using transesterification of triglyceride biomass with a light alcohol [ 1 , 2 ] has already entered in the fuel market as a very promising alternative to petro–diesel, its utilization without mixing with the latter is still problematic. Biodiesel is very unstable (at low temperature it is prone gelling and at high temperature it grows mold), it may damage filters and pipes of the existing vehicles and has lower fuel efficiency than petro–diesel [ 2 ].…”

“…Biodiesel has some distinct advantages over petrodiesel. For example, biodiesel possesses higher cetane number (CN) and lubricity, contains less sulfur and aromatics, and emits less green‐house gases 6 . However, some problems and concerns associated with biodiesel are limiting its wide application in automotive sectors.…”

For example, biodiesel has higher viscosity, higher density, and lower calorific value that lead to poor engine performance.…”
