“…Carbon monoxide is a product of the partial combustion due to the deficient amount of air in the air-fuel mixture. The reduction in the carbon monoxide emissions for the biodiesel is due to the oxygen molecule present in the fuel and the lower carbon content as related to that of the diesel fuel which leads to the better combustion[22][23][24][25] Effect of engine brake power on CO Emission for biodiesel blended proportions (B10, B15, B20 and D100).…”

Background: The world depends almost on fossil fuels. This leads to depletion of oil and an increase in environmental pollution. Therefore, the researchers search to find alternative fuels. Waste cooking oil (WCO) was selected as feedstock for biodiesel production to eliminates the pollution problems. The agricultural waste is very big and without cost, this leads to the use of the rice straw in preparing a catalyst for biodiesel production. Results: The reusability of the acidic catalyst confirmed that the conversion efficiency was high until after 8 cycles of the production. The highest conversion efficiency of the converting WCO extended to 90.38% with 92.5% maximum mass yield and methyl ester content 97.7% wt. at the optimized conditions. The result was indicating that B15 is the best blend for thermal efficiency and specific fuel consumption. All emission concentrations decrease with increasing the engine load, especially for B15 fuels compared to the diesel oil.Conclusion: The novelty of this paper is assessing the methyl esters from the local WCO as an alternative fuel for diesel engines using a heterogeneous catalyst based on the agricultural waste. The performance of the diesel engines and its exhaust emissions have been experimentally investigated with the produced biodiesel of WCO as a blend (B10, B15, and B20) compared to the diesel.

The energy problems and global warming has led to intense research into the existence of alternative fuels with high efficiency and high calorific value. Oily plants have a high calorific value when using the resulting oil, especially palm oil. The search for alternative fuels has always conflicted with the use of edible oils. This paper aims to study the effect of cooking times on biodiesel production from oil. The study was applied to different samples of used waste cooking oil (WCO) for several times, the samples were fresh oil, oil cooked for several times: 3, 6, 9 and more than 9 times (local WCO). The best yield of biodiesel is about 97% for local WCO. The biodiesel color is clear as the Lovibond No. dwindles down which means less FFA% and good quality of biodiesel. This method can be using to decrease density and viscosity of biodiesel and oil to be like diesel. The best preheated temperatures are 60 °C for biodiesel and about 100°C for oil. Cetane number increased with increasing number of using oil . The local WCO is the best Cetane number. But Calorific value is best with fresh oil and local WCO. The local WCO is the optimum selection condition.

This current work displays experimental results obtained from assessing the methyl esters from the local waste cooking oil as an alternative fuel for diesel engines using a heterogeneous catalyst based on agricultural waste. The performance of the diesel engines and their exhaust emissions have been experimentally investigated using the produced biodiesel from waste cooking oil as a blend with fossil fuel (B10, B15, and B20) compared to the diesel. The reusability of the catalyst confirmed a high conversion efficiency after 8 cycles of the production. The highest conversion efficiency of the converting waste cooking oil extended to 90.38% with 92.5% maximum mass yield and methyl ester content of 97.7% wt. at the optimized conditions. According to the results, the effective blend for thermal efficiency and specific fuel usage is B15. Also, all emission concentrations decrease with increasing the engine load, especially for B15 fuels compared to diesel oil.
