“…The credit for this reduction falls on the biodiesel's lower calorific value, which lowers the cumulative energy of the test fuel blend [29,30]. The examination also revealed that the incorporation of TiO2 nanoparticles of various sizes enhances the brake thermal efficiency of the engine [31]. Moreover, among the three sizes of TiO2 nanoparticles, the optimum values of BTE are noted for the blend containing the nanoparticles of size 3050 nm size as compared to those of 1030 nm and 5070 nm.…”

Most countries in the world are facing two major challenges, one is the increase in the demand for energy consumption difficult to fulfill because of limited fossil fuel, and the second is the emission norms specified by many countries. Various methods are adopted to reduce emissions from engines but that leads to sacrificing the performance of CI engines. To eradicate this problem in the present study, the nanoparticles like (TiO2) are used with different particle sizes 10–30 nm, 30–50 nm and 50–70 nm induced in B20 (20% biodiesel and 80% diesel) with the constant volume fraction of 100 ppm, and utilized in the diesel engine without any modifications. The results showed that the incorporation of TiO2 nanoparticles improves the combustion of hydrocarbons and reduces the emissions of CO, unburned hydrocarbon concentration, NOx and soot. Moreover, among three sizes of the nanoparticles, those with size 30–50 nm showed interesting results with the reduction in brake-specific energy consumption, NOx, smoke and HC by 2.9%, 16.2%, 35% and 10%, respectively, com-pared to other blends used in the study, and hence the blend with the nanoparticle of size 30–50 nm is expected to be a more promising fuel for commercial application in CI engines.

“…31 The results also revealed that the addition of nano additives to the diesel-biodiesel blend causes an improvement in BTE compared to neat diesel and biodiesel blends. 32 The reason for this is nano additives are high energy density additives. Also, it has a surface-to-volume ratio and high catalytic activity which improves the fuel-oxidizer contact leading to improved combustion resulting in increased BTE.…”

Recently nano additives have proven their significance in biodiesels to overcome the challenges of fossil fuels in CI engines. The current study examines the performance and exhaust emission characteristics of a CI engine on waste cooking oil biodiesel (WCME) blends with Titanium oxide (TiO2) nano additives. TiO2 of 50 and 100 ppm were added in WCME blends with the help of magnetic stirring, followed by ultrasonication. Test fuel with 100 ppm of TiO2 and WCME30 (30% WCME and 70% neat Diesel) showed a 4.04% improvement in brake thermal efficiency and a 3.3% decrement in BSEC. Moreover, lowered NOx, HC, and CO exhaust emissions by 1.7%, 14%, and 17.46% respectively than neat Diesel. So WCME30 with 100 ppm concentration of TiO2 can be utilized as a potential fuel for a single cylinder four-stroke compression ignition engine with the compression ratio of 18:1.

In this research, the optimum condition for the production of refined crude palm oil methyl ester from refined crude palm oil was investigated using the response surface method via the transesterification reaction in a batch process. The refined crude palm oil was obtained by vacuum distillation of crude palm oil to extract some of the free fatty acids from the oil, providing nutritional benefits and reducing the chemical consumption of the production process. The purity of methyl ester in the refined crude palm oil methyl ester was studied to adjust four independent variables: methanol content (11–23 vol %), concentration of potassium hydroxide (4–12 g/L), stirrer speed (100–500 rpm), and reaction time (9–45 min). The results showed that methyl ester had a purity of 96.91 wt % when synthesized under optimal conditions of 18.2 vol % methanol, a potassium hydroxide concentration of 10.0 g/L, a stirring speed of 380 rpm, and a reaction time of 36.4 min at 60 °C. Refined crude palm oil methyl ester was blended with diesel and ethanol to study the feasibility of using the diesel–refined crude palm oil methyl ester–hydrous ethanol blend in an unmodified diesel engine. A comparative study of fuel properties, emissions, and performance of the diesel–refined crude palm oil methyl ester–ethanol blend was used to assess the feasibility of fuel blends (D40RM50E10, D30RM60E10, D20RM70E10, and D10RM80E10) in diesel engines at various engine speeds and loads. The results showed that the D40RM50E10 blend provided the closest performance to diesel and was environmentally friendly, as it provided nitrogen oxide and carbon monoxide emissions 32 and 55% lower than those with diesel, respectively. The test results indicated that the diesel–refined crude palm oil methyl ester–hydrous ethanol blend is an attractive alternative fuel in agricultural engines that reduces diesel consumption and benefits farmers and rural communities.
