“…In engine tests of single component esters produced from various straight and branched short chained alcohols (methanol to tert-butanol), Hellier et al 62 found an observable increase in the duration of ignition delay relative to the equivalent FAME (methyl stearate) only in the case of the ester with the most branched alcohol moiety (tert-butyl stearate). Other studies of esters with branched alcohol moieties have either found no change in ignition quality 63 , or a slight increase in the duration of ignition delay in the case of the most branched alcohol moiety 56,64 .…”

Renewable alternatives to fossil fuels are necessary for the reduction of anthropogenic greenhouse gas emissions, the increased atmospheric concentrations of which are resulting in global climate change. Biodiesel, fatty acid esters prepared from the reaction of triglycerides with alcohols, is a potentially sustainable fuel for compression ignition combustion, and is already widely used to displace fossil-derived diesels. However, there is a wide range of potential feedstocks suitable for the production of biodiesel, and the composition of these oils and alcohols can have a significant impact on the combustion characteristics of the resultant biodiesel. Therefore, this paper presents a review of biodiesel composition from various sources, and the effects of differing composition on combustion phasing and the emissions of regulated pollutants, NOx and particulate matter, in compression ignition engines. The primary influence of biodiesel composition on fuel ignition delay is through the fatty acid alkyl moiety, with either an increase in alkyl chain length or degree of saturation reducing the duration of ignition delay. NOx emissions levels are determined through in-cylinder temperature conditions, most strongly influenced in common rail injection systems by the duration of ignition delay and in mechanical injection systems by injection timing, which advances with increasing biodiesel bulk modulus. Emissions of particulate matter increase with biodiesel physical properties, such as boiling point or viscosity, which increase with both increasing fatty acid moiety and alcohol moiety chain length.

Significant concerns over energy security and environmental impact reduction will drive all stakeholders to generate proper alternative energies. Biodiesel is a prospective cleaner-burning biofuel that can contribute on addressing these concerns globally. Presently, pure biodiesel (B100) application is still facing several obstacles, principally in terms of its cold flow properties. Improvement in cold flow behavior parameters is the solution to promoting biodiesel implementation at a higher percentage and wider environmental temperature range. This study provides a detailed review of several improvement methods, both physical, chemical, and biological, from various scientific sources, to elevate the cold fluidity characteristics of biodiesel. The investigated methods convincingly offer proper enhancement in the cold flow properties of biodiesel. Mostly, this improvement is accompanied by an alleviation in oxidation stability, cetane number, and/or viscosity. However, the skeletal isomerization method presents promising cold fluidity refinement with minimal reduction in other physical properties. Therefore, the continuous development of these methods promises global sustainable application of high-quality biodiesel.
