“…In the year of 2014, the total number of animals that were slaughtered during the pilgrimage season was about 2.5 million in Saudi Arabia (Nizami et al 2017). Poland produces 380 tons of animal fat per year, and this can be used for transesterification purposes (Cisek 2018). Animal slaughter waste from goats as well as sheep is about 12% per unit of weight of the body, whereas, for cattle, it is around 38% per body weight (Nizami et al 2017).…”

“…The combustion process of a high ethanol content blend is delayed at low loads but approached to that of the diesel fuel at high loads. Cisek (2018) reported that hourly advanced motor fuel (AMF) consumption is about 9% higher than for standard diesel fuel (DF). The overall efficiency of the engine is lower by about 7% for the AMF-powered engine than for DF fueled engine.…”

“…The overall efficiency of the engine is lower by about 7% for the AMF-powered engine than for DF fueled engine. Use of AMF and DF decreases CO, HC, and smoke concentration (up to 37%), at the expense of increasing NOx in exhaust gases (about 4%) (Cisek 2018).…”
Due to the ever-increasing consumption of fossil fuels, their impact on the environment, and the volatility of the market, it is advisable to use biofuels that can be produced locally from renewable sources, which supports the local economy, agriculture, and related processing industries. This article deals with how to improve the flow properties and pour point of biofuels for diesel engines. For the experiment, biodiesels in the form of rapeseed methyl ester (RME) and methyl ester made from waste animal fats and tallow (WAFME) were used. The pour point, viscosity, and density of WAFME were improved by mixing with RME and/or by adding bio-alcohols (alcohols produced from biomass, e.g., lignocellulosic). All used biofuels were classified as 2nd generation biofuels. The flow properties of the mixtures were monitored and subsequently modelled at temperatures from -10 to 60 °C. The addition of bio-alcohol had a statistically significant effect on the decrease in the viscosity and pour point of ternary blends (p < 0.05). Mathematical models of the dependence of kinematic viscosity on the temperature of mixtures (power law, exponential, Arrhenius, and Vogel) were created.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
