“…In addition, unburnt hydrocarbons, carbon monoxide (CO), nitrogen oxides (NOx), particulate matter, sulfur oxides, and soot are the main pollutants emitted by engines operating on diesel fuel, particularly in urban areas with high population density. Such pollutants have a tendency to aggravate environmental problems such as acid rain, climate change, global warming, and smoke and have a detrimental impact on human health (Reşitoğlu et al, 2015;Ibrahim et al, 2016;Alhamdany et al, 2018;Vellaiyan et al, 2018;Hamid et al, 2020). Because of the fast depletion of fossil fuels and growing concern for the climate and human health, both engine manufacturers and researchers are being forced to look for alternatives that are reliable, low-cost, and environmentally friendly.…”

A deep understanding of the ignition characteristics of syngas-diesel under different lambda values is essential for the application of dual-fuel combustion. In this study, the effect of increasing the lambda value was examined along with the emission characteristics and engine performance of syngas-diesel dual-fuel engines under a constant syngas-to-diesel substitution ratio of 52% at 2000 rpm engine speed. The work involved computational fluid dynamics analysis related to combustion for a four-stroke single-cylinder direct-injection engine. Combustion analysis was carried out using ANSYS Workbench (FLUENT) V16.1 software. According to the simulation results, the maximum pressure, temperature, and nitric oxide emission inside the combustion chamber increased with each increase in the value of lambda, while the emission of carbon dioxide and carbon monoxide decreased inside the engine.

“…The changes in the physicochemical properties and exhaust emission parameters of the blends composed of different feedstock biodiesel and diesel fuel were compared in many works (264,265). The higher oxygen level of biodiesel compare to fossil fuel leads to complete combustion of the fuel in a diesel engine and results in lower UHC and CO, and PM emission (266). The addition of the limited concentration of water to biodiesel causes a micro-explosion phenomenon and stimulates a more combustible air-fuel mixture, which was reported as a method of the NO x and PM emissions reduction (267).…”

Although fossil fuels remain the main source of energy, the volume of renewable sources of energy is constantly increasing. Biodiesel is a promising alternative fuel due to the number of advantages compared to fossil fuel and other types of biofuel. The specific objective of this study was to identify the difference between conventional and novel technologies applied during the whole life cycle of biodiesel production and consumption. The study offers some important insights into the recent advances in the biodiesel industry including biodiesel production from microalgal lipids, advanced homogenous and enzymatic transesterification, non-catalytic supercritical transesterification, application of microwave and ultrasound assisting technologies. Considering all the factors affecting the efficiency and safety of the biodiesel production process, here we reviewed the main principals and recent achievements in the environmental life cycle assessment of biodiesel production and consumption.

In the field of drilling there is increasing interest in topics such as degradation of drilling tools and estimation of penetration speed, as well as efforts to optimize geometrical parameters and drilling processes. The current study was based on an original experimental setup that estimates the actual operating conditions of drilling tools and proposed mathematical models with and without interactions. These models characterize the penetration speed of a widely used compact polycrystalline diamond (PDC) oil-drilling bit. The special focus of this study was on the cutter penetration bit, with the aim of investigating the influence of four operating variables weight on bit (WOB), bit rotational speed (RPM), cutting angle , and compressive strength Cs on yield maximum penetration rate, using Taguchi's design-of-experiment concepts. In the study, 27 experimental runs based on Taguchi's L27 orthogonal array were performed with signal to-noise (S/N) ratio, analysis of variance (ANOVA), and regression analysis being used, with penetration rate as response variables. From the optimization and experimental analyses conducted, it was observed that WOB3 (160 kgf), RPM3 (152 rpm), 3 (45), and Cs1 (640 kgf/cm 2) had significant influence on penetration rate. The optimal values obtained during the study optimization using the Taguchi approach were validated by confirmation experiments.
