“…Biodiesel can also be produced from a wide array of feedstocks such as waste cooking oil, edible and non-edible oil seeds, wood and wood waste etc. [11][12][13]. Research and development is also ongoing to produce biodiesel from microalgae [14]; however, this is still in the development stage.…”

The study investigated the engine performance and emission using biodiesel from soybean oil and waste cooking oil. The fuel properties of these biodiesels were determined using ASTM D6751and EN 14214 standards. The fuels were tested in a multi-cylinder diesel engine with an electromagnetic dynamometer and a 5-gas analyser was used for emission analysis. The result shows that the thermal performance of the engine slightly decreases with increase of the biodiesel blends ratio (i.e. B5, B10, B15, B20 and B50). On the other hand, emission decreases with the increase of biodiesel blends. The reduction in emissions was different for both biodiesels. Waste oil biodiesel showed better trends of emissions reduction with increase of the biodiesel percentage compared with soybean biodiesel. The brake specific fuel consumption (BSFC) of both biodiesels is (6.05%, 9.13%, 12.36% and 18.57% for soybean) and (8.17%, 11.40%, 17.71% and 14.96% for waste cooking oil) higher than diesel, respectively. However, soybean biodiesel consumed less fuel and produced more power and torque compared to waste oil biodiesel. The study concluded that B10 soybean biodiesel blend produced more consistent and expected results than waste oil biodiesel from the performance and emission point of view.

“…BSFC is an important parameter of an engine because it incorporates both the mass flow rate and the heating value of the fuel. BSFC of all blends of biodiesel is higher than that of petroleum diesel at various loading conditions (Gopal & Karupparaj, ; Gopal et al., ; McCarthy, Rasul, & Moazzem, ). This may be due to high viscosity, density, and lower heating values of biodiesel.…”

“…CO formation depends on the air–fuel equivalence ratio, fuel type, combustion chamber design, injection timing, injection pressure, and speed. CO emission decreases with the increased amount of biodiesel in the blend (McCarthy et al., ). The variation of CO emission with brake power for various biodiesel blends and diesel is presented in Exhibit .…”

“…NOx emissions depend on a number of factors, such as biodiesel type, engine type, and test procedures used. NOx emissions from all biodiesel blends are higher than those from conventional diesel (Gopal & Karupparaj, ; McCarthy et al., ; Paul et al., ). This may be due to the high combustion temperature and the presence of extra oxygen.…”

“…This may be due to the high combustion temperature and the presence of extra oxygen. NOx emissions can be reduced by adjusting the injection timing and recirculating a small portion of exhaust gas with fresh air during the induction process (McCarthy et al., ). Harch, Rasul, Hassan, and Bhuiya () found that diesel fuel had the highest fraction of NO after complete combustion, followed by B5 biodiesel (blend of 5% biodiesel), which was approximately 3% lower, and B10 biodiesel (blend of 10% biodiesel), which was approximately 14% lower.…”

The depletion of fossil fuel reserves and increasing demands for diesel are considered to be important triggers for many of the initiatives that have been taken to search for possible sources for the production of biodiesel from materials available within the country. It is possible to produce biodiesel from waste/used cooking oils (WCO) that is comparable in quality to that of fresh vegetable oil. Not only does reuse of WCO, which can otherwise harm human health, reduce the burden on the government of treating oily wastewater, disposing of the waste, and maintaining public sewers, it also significantly lowers the production cost of biodiesel. In the process of frying, oil undergoes many reactions, leading to the formation of a number of undesirable compounds, such as polymers, free fatty acids, and many other chemicals. This poses challenges in the transesterification of WCO. This article covers different techniques in the production of biodiesel from WCO.It also compares combustion, emissions, and engine performance characteristics of biodiesel from WCO as well as factors affecting biodiesel production from WCO and its economic feasibility.
