“…Besides, waste cooking oil (WCO) significantly reduces the cost of production of biodiesel since it is cheaper than the raw materials mentioned above. In addition, the fact the use of WCO has no negative impact on food safety increases the importance of using it as a raw material in biodiesel production [5][6][7].…”

In this study, bioethanol produced from sugar beet and biodiesel produced from waste cooking oils was blended with each other in the volumetric rates to be 20% and 80%, respectively. Cetane improver (di-tert-butyl peroxide) was added into blend fuel in 1-2-3% as volumetric. The obtained blends were used as a fuel in the diesel engine which is single-cylinder, directinject, four-stroke. The tests were conducted under four different engine loads (25%, 50%, 75% and 100%) and 1400 rpm engine speed. The test results showed that brake-specific fuel consumption was decreased up to 15.5% thanks to the addition of cetane improver, although biodiesel and bioethanol increased brake-specific fuel consumption by 16.1% and 27.54%, respectively. However, brake thermal efficiency values were increased up to 9.44% with both biodiesel and cetane improver added blend fuels, while brake thermal efficiency was decreased by 3.88% with bioethanol addition. The more compatible combustion characteristics with that of diesel fuel have been obtained due to especially the increase in cetane number. The use of biofuels increased both maximum cylinder pressure and heat release rate. While, with the cetane improver addition, a decrease in CO, HC and smoke opacity values was observed up to 22.5%, 17.44% and 24.44%, respectively, CO 2 , NO X and exhaust gas temperature values were increased up to 19.55%, 5% and 15.22%, respectively, according to bioethanol blend fuel.

“…The issues related to the increase in energy demand, fossil fuel depletion, and environmental pollution are considered so urgent that we must find renewable and alternative fuels to replace fossil fuels with the aim of maintaining fresh air and ensuring energy safety (Abubakar et al, 2016;Anh Tuan & Minh Tuan, 2009). Biodiesel produced by the transesterification reaction of oils or fats that are originated from edible and non-edible vegetable oils and animal fats are considered potential alternative fuels with environmentally friendly, non-sulfur, and non-toxic properties (Rajagopal et al, 2016;Liu et al, 2017).…”

Biodiesel has been considered as the potential fuel type with many advantages such as environmental pollution reduction, no sulfur production, and biodegradation. However, disadvantages of biodiesel such as high viscosity and high density affected diesel engines and fuel systems negatively. Thus, it is necessary to reduce the viscosity and density of biodiesel fuel in unmodified diesel engines. Until now, a large number of empirical correlations have been used to predict the viscosity and density of biodiesel-fossil diesel fuel blend This study was conducted to predict the kinematic viscosity and density of blends of biodiesel and fossil diesel fuel. Three types of biodiesel were examined: Coconut oil-based biodiesel (COB), Jatropha oil-based biodiesel (JOB), and Waste oil-based biodiesel (WOB). Twenty-four samples of the three types of biodiesel-diesel fuel blends were created by blending 5% (B5), 10% (B10), 20% (B20), 40% (B40), 50% (B50), 60% (B60), 75% (B75), and 100% (B100) of biodiesel with conventional diesel fuel to produce the corresponding blends for experimental purposes. Experimental correlations and mathematical equations for predicting the relationship between the kinematic viscosity and the density of the biodiesel-fossil diesel fuel blends, the dependence of the kinematic viscosity and the density of the biodiesel-fossil diesel fuel blends on biodiesel fractions, and the effects of temperature on the kinematic viscosity and density of pure biodiesel were developed. The results of the experimental correlation data were near the predicted mathematical equation with a confidence level of 95%.

“…According to the results, 1.0 wt% catalyst concentration, 30 wt% methyl alcohol to oil, 60οC temperature of reaction, 400 rpm rate of agitation and 60 min time of reaction are optimum parameters for production biodiesel from moringa oleifera oil. Abubakar et al, (2016) studied the process parameters of waste cooking oil biodiesel production. According to the results, the highest biodiesel conversion rate was acquired with 0.5% concentration of catalyst, 6:1 alcohol to oil ratio, 30°C operating temperature, 60 min transesterification time.…”

Biodiesel is biodegradable, renewable and nontoxic fuel source instead of petroleum fuel.Biodiesel has bad cold flow properties. The aim was to specify the optimum reaction parameters and obtain minimum cold flow properties. Transesterification method was preferred as the biodiesel production method. Reaction of transesterification is affected by diverse reaction parameters like as catalyst amount, molar ratio of alcohol to oil, time of reaction and temperature of reaction. In this experimental study, the impacts of operation parameters on cold flow properties of linseed oil biodiesel was compared. In production process potassium hydroxide (KOH) was chosen as catalyst and ethanol was used as alcohol. The impacts of
