“…Despite increasing the cetane number, the increase in the DFX rates is thought to cause effective efficiency to drop for DFX3 and DFX5 due to decreasing the lower heating value. One can see that there is a reasonable compatibility between the effective efficiency obtained within this study and the other research results [6,[16][17][18][19][20][21].…”

“…As seen in the figure, CO2 emission increased with the increasing engine load and DFX mixtures reached higher CO2 emission values compared to diesel fuel. The increasing of CO2 emission with the increasing engine load is a result of DFX mixtures increasing the cetane number of the fuel together with its evaporation speed [1,6,12,19,31]. When the CO2 emissions of the DFX1, DFX2, DFX3 and DFX5 fuels were compared with DFX0 fuel an increase was observed by 17.56%, 28.04%, 26.91% and 32.29% on average, respectively.…”

Current study uses DieselFX (DFX) additive to increase the cetane number of the diesel fuel used in compression-ignition (CI) engines, reduce carbon monoxide (CO) and hydrocarbon (HC) emissions, and improve engine performance. In this respect, the effects of the additive used in diesel engines were analyzed. A Katana brand, KM 178 FE model, single-cylinder, air-cooled engine was started at a constant engine speed with different loads for the experiments. By adding the additive in 1% and 2% ratios the cetane number was increased to 62 and 75, respectively, furthermore at 3% and 5% additive ratios the cetane number value reached over 76. In result of the experiments, DFX2 offers 12.24% increase on efficiency compared to the diesel fuel and 6.87% increase in specific fuel consumption. As for the emission values, with the use of DFX5 44.23% reduction in HC emission and 50% reduction on average in CO emission was observed at 3000W load compared to additive-free diesel fuel. Moreover, 37.84% increase was observed in carbon dioxide (CO2) emission at 3000W engine load for DFX2 whereas 52.11% increase was observed in nitrogen oxide (NOx) emission for DFX5.

“…From several cetane improvers, 2-Ethylhexyl nitrate (EHN) is preferred for this study as it is a commercial product that is readily available in the market at a low cost. The free radicals promoted by the EHN during the fuel combustion enhances the acceleration rate of the combustion process that can reduce the IDP [24,25].…”

Waste-to-energy and its utilization in the commercial field have received wider attention in recent years. Lemon peel oil (LPO), a food waste by-product is used for this study to produce bioenergy, and a novel approach has been attempted to improve energy and environmental efficiency. The LPO was blended different percentages of water and 2-Ethylhexyl nitrate (EHN) and the energy, environmental and economic assessments were carried out. The outcomes show that LPO dominates the normal diesel in all aspects, except for NOx emission, and 10% of water in LPO (10WLPO) improves the overall performance. Meanwhile, this trend is reversed for 20% water in LPO (20WLPO) due to longer ignition delay period and low cetane numbers. EHN plays a vital role in fuel modification and EHN blended 20WLPO significantly improves the engine characteristics, and the engine behaviour is identical to 10WLPO. The cost-benefit analysis shows that 10WLPO fuel significantly reduces the running cost by 4.5% compared to neat diesel, and the cost is further reduced to 9.2% while the LPO is blended with 10% water.

“…The main thermal degradation products of aand b-pinene were analyzed under an air atmosphere. There have been many reports on the effect of turpentine as an additive on fuel, 5,6 and the effect of emissions on the environment. 7,8 Their research results show that the combustion performance of turpentine is good, and the emissions of HC, CO, PM and NO x are slightly reduced.…”
