“…These results are well aligned with research by Liquat et al [60]. A higher cetane number and ignitability of COB and its blends are attributable to enhanced combustion [70]. In addition, COB is oxygenated with a 14.3% wt oxygen content in it.…”

Renewable alternatives to fossil fuels, such as biodiesel, are necessary to lessen emission of greenhouse gases that are causing climate change. Using a high-pressure, medium-duty, common-rail, turbocharged four-cylinder diesel engine, this work studies the effect of adding Cocos nucifera biodiesel to conventional diesel on exhaust emissions, engine performance, and combustion characteristics. An analysis and characterization of the key physicochemical properties of diesel, biodiesel, and biodiesel–diesel blends were carried out. The engine was fuelled with pure petroleum diesel and blended diesel containing a 10%, 20%, 30%, and 50% volume of coconut oil at full throttle and six different speed settings, respectively. The results showed relatively close physicochemical properties between the biodiesel blend and conventional petroleum fuel. Observations made over the entire speed range indicated that a higher coconut oil biodiesel (COB) content lowers the torque and brake power compared to diesel. In the case of engine exhaust gas, a reduction in carbon monoxide (CO) and smoke emissions were observed. Notably, COB50 gives out the highest nitrogen oxides (NOx) but it is raised even for other blends. The experimental results also demonstrated that a higher COB content achieves a lower peak pressure while the peak heat release rate (PHRR) was lower than that of conventional diesel as the speed of the engine increases.

“…Its physicochemical properties are similar to petroleum derived diesel fuel (DF). Blends (mixtures) of DF and HVO did not result in elevated CO 2 emissions or fuel consumption. , Moreover, a reduction of emissions of carbon monoxide (CO), total hydrocarbons (HC), and nitrogen oxides (NO X ) was shown following combustion of a 30% blend with DF in a heavy duty engine . Combustion of blends in three different light duty vehicles yielded decreased CO, HC, and particulate matter (PM) emissions and reduced aldehydes, 1,3-butadiene, benzene, particle-bound polycyclic aromatic hydrocarbons (PAHs), and bacterial mutagenicity of the exhaust .…”

Research on renewable fuels has to assess possible adverse health and ecological risks as well as conflicts with global food supply. This investigation compares the two newly developed biogenic diesel fuels hydrotreated vegetable oil (HVO) and jatropha methyl ester (JME) with fossil diesel fuel (DF) and rapeseed methyl ester (RME) for their emissions and bacterial mutagenic effects. Samples of exhaust constituents were compared after combustion in a Euro III heavy duty diesel engine. Regulated emissions were analyzed as well as particle size and number distributions, carbonyls, polycyclic aromatic hydrocarbons (PAHs), and bacterial mutagenicity of the exhausts. Combustion of RME and JME resulted in lower particulate matter (PM) compared to DF and HVO. Particle numbers were about 1 order of magnitude lower for RME and JME. However, nitrogen oxides (NOX) of RME and JME exceeded the Euro III limit value of 5.0 g/kWh, while HVO combustion produced the smallest amount of NOX. RME produced the lowest emissions of hydrocarbons (HC) and carbon monoxide (CO) followed by JME. Formaldehyde, acetaldehyde, acrolein, and several other carbonyls were found in the emissions of all investigated fuels. PAH emissions and mutagenicity of the exhausts were generally low, with HVO revealing the smallest number of mutations and lowest PAH emissions. Each fuel showed certain advantages or disadvantages. As proven before, both biodiesel fuels produced increased NOX emissions compared to DF. HVO showed significant toxicological advantages over all other fuels. Since jatropha oil is nonedible and grows in arid regions, JME may help to avoid conflicts with the food supply worldwide. Hydrogenated jatropha oil should now be investigated if it combines the benefits of both new fuels.

“…This results in increased NOx emissions in biodiesel because biodiesel is a fuel that has higher oxygen content than diesel but leads to a lesser calorifi c value of biodiesel than diesel. This is coupled with power losses and more fuel consumption, which increases the water and carbon dioxide content [77][78][79]. The blending of soybean oil biodiesel could be done with short chain methyl esters having fatty acids -caprilic (C8:0) and capric (C10:0).…”

We all are aware that the depletion of the fossil fuel reservoirs has lead to an urgent search for alternative forms of present day fuels. The possible solution could come from biofuels, especially biodiesel. Biodiesel could be produced from plants, microorganisms, fungi, wastewater, microalgae etc., but these sources suffer from one or more drawbacks. However, microalgae could serve as the best source for biodiesel production since it does not lead to a land versus fuel confl ict. This chapter is mainly focused on the sources for the production of biodiesel, biodiesel production processes, catalysis involved and the factors affecting biodiesel production. We have to understand that for the best utilization of biodiesel in diesel engines, we have to incorporate technical modifi cations in traditional diesel engines so that biodiesel production could be promoted commercially.
