“…Given its higher calorific value and higher oxygen content over a broader range of engine load conditions, the Blend G generated 316.50% compared with Blend A and had the lowest CO emissions of all fuel blends tested. In accordance with Ramalingam and associates, 51,61,62 the operation of ternary fuels resulted in CO emissions that were comparable to those produced by diesel fuel, and that these emissions were dependent on ethanol concentration, the synergetic impact of atomization, the cetane number, and the latent heat of vaporization, among other variables. In a similar vein, Di and associates 35,63 discovered that by decreasing the temperature of the combustion chamber, CO emission is reduced in proportion to the amount of oxygen present.…”

“…50 HC emissions from Blend B and comparable blends are far lower than those from diesel fuel, due to the presence of oxygen in the fuel's chemical composition. 51 Furthermore, the cetane number of biodiesel is critical for HC synthesis because it creates ketone substrates from unburned HC, which is required for HC formation. In spite of this, there have been no observed ketone substrates in diesel combustion, 52 and the amount of O 2 molecules in diesel combustion is much higher than in gasoline.…”

The study includes the use of alcohols in conjunction with diesel as a binary fuel and biodiesel. In addition, this study was conducted on quaternary fuels (premium diesel, waste cooking biodiesel, n‐butanol, and bioethanol), including Fe3O4 (iron(III) oxide)‐doped reduced graphene oxide (rGO) nanocomposite to reduce the use of fossil fuels, their cost, and energy demand. It includes 10% bioethanol, 5%–20% n‐butanol, 25 ppm Fe3O4‐doped rGO nanocomposite, and 20% and 100% waste cooking biodiesel, all of which have been tested in a diesel engine to ensure that they are suitable for use. The findings were compared to those obtained with premium diesel, ranging from 50% to 100% at full engine load conditions. In comparison to 100% premium diesel fuel, the fuel blend (Blend G) had 37.50% brake thermal efficiency and 0.46% (brake‐specific energy consumption), as well as lower rates of 316.2% carbon monoxide, 198.80% hydrocarbon, and 80.01% smoke with 28.10% higher oxides of nitrogen (NOx). Adding 20% n‐butanol to premium diesel, as well as waste cooking biodiesel, bioethanol, and Fe3O4‐doped rGO nanocomposite fuel blends, was used in this study to improve the performance of the diesel engine and reduce some of the NOx emissions. In the near future, these fuel blends may be a viable alternative combination for the diesel engine.

This study reports on the delignification of Prosopis juliflora biomass using microwaveassisted alkaline pretreatment. Response surface methodology was employed to analyze the effect of process variables on delignification. Four independent process variables such as microwave irradiation power (270-450 W), microwave irradiation time (3-5 min), alkali concentration (0.75-1.25% wt/vol) and liquid to solid ratio (LSR; 10-20 mL/g) were analyzed. A second-order nonlinear equation was developed to validate the model. The experimental results suggested that all the variables exhibited a similar response. The developed model was statistically valuated using analysis of variance. The optimum conditions determined from the study were as follows: microwave power of 360 W, irradiation time of 4.40 min, alkali concentration of 1.24% wt/vol and LSR of 13.16 mL/g. Maximum delignification of 75.12% was obtained using microwave-assisted alkali pretreatment method. The delignified Prosopis juliflora biomass was characterized using scanning electron microscopy and Fourier transform infrared spectroscopy studies. It was confirmed that microwave-assisted alkali pretreatment for a short duration facilitated maximum removal of lignin from biomass. The present study, therefore, helps in developing a suitable strategy both for satisfying the energy need and management of the exotic weed.

The world’s energy demand increases because of increase in human population. The conventional fossil energy resources will be depleted and burning of these conventional fuels increases greenhouse gases and causes global warming. These problems can be overcome using renewable alternative energy resources such as biofuels. In recent years biodiesel is considered as a renewable alternative to the fossil diesel. The utilisation of biodiesel as a fuel in compression ignition engine results in lower CO, HC and Smoke emissions as the biodiesel is an oxygenated fuel. The major problem with the biodiesel is its higher NOx emission and different techniques were used to minimise NOx emission. The use of synthetic and nano-metal additives to the biodiesel may affect the environment and hence it is necessary to identify non-toxic, low cost, biodegradable, and sustainable additives to reduce the NOx emission. Hence an attempt was made to use clove oil as a natural additive for the honge oil biodiesel as it has better antioxidant property. The engine tests were conducted with various dosages of clove oil such as 1000 and 2000 ppm and the engine load were increased with an increment of 25% up to full load. The addition of clove oil to the honge oil biodiesel significantly affects the engine NOx and clove oil can be substituted as an additive to reduce the NOx emission of the biodiesel fuelled CI engine and without altering the engine hardware. The clove oil enhances the oxidation stability of the honge oil biodiesel.
