The continuous population increase in many developing and developed countries leads to an increase in CO2 and SO2 emissions and oil consumption at an alarming rate in many sectors, mainly the transportation sector. As a result, natural gas is rapidly…
Within the context of the energy transition, there are several alternatives under study for the gradual replacement of diesel fuel based urban transport vehicles. This paper proposes an answer to the following question: Which bus technology and…
This study aims at performing the first comprehensive Well-to-Tank (WtT) energy consumption and greenhouse gas (GHG) emission analysis of 10 different petroleum and natural gas fuels pathways, i.e., gasoline, diesel, CNG and LNG, in Pakistan. The…
In this study, natural gas and diesel dual-fuel combustion in a heavy-duty compression ignition engine is experimentally evaluated by adopting a modified multi-angle nozzle of a diesel injector to reduce the global warming impact (GWI) factor while…
While developed nations are accustomed to the challenge of intermittent renewable sources on a stable grid, for the developing world, the problem is different: the grid itself is unreliable. Those affected turn to diesel backup generators. Once this…
The continuous population increase in many developing and developed countries leads to an increase in CO2 and SO2 emissions and oil consumption at an alarming rate in many sectors, mainly the transportation sector. As a result, natural gas is rapidly…
Soot particles, released during diesel combustion, adversely affect human health and the environment. Some studies suggest blending diesel with oxygenated fuels to reduce soot emissions, though it also reduces fuel economy and may produce new…
In the face of lacking an equation to predict important characteristics of new biofuels, thirty mixing rules originally developed to calculate the viscosity of petroleum and its fractions were tested, using 303 experimental data of biodiesel and…
Diesel fuel combustion generates soot particles, which are harmful for human health and the environment. To reduce soot emission, various solutions are proposed in the literature such as the use of metal-additives in fuels, fuel blending with…
Diesel molecular compositional model has important application for diesel quality prediction, blending, and molecular-level process model development. In this paper, different types of diesel molecular compositional and blending models were…
Experiments have shown that as a pilot fuel, n-butanol-diesel blend can further ameliorate the performance and emissions of natural gas (NG) dual-fuel engine. A skeletal n-heptane-toluene-n-butanol-methane-ethane-propane (HTBMEP) mechanism including…
Within the context of the energy transition, there are several alternatives under study for the gradual replacement of diesel fuel based urban transport vehicles. This paper proposes an answer to the following question: Which bus technology and…
The combination of diesel and natural gas fuels has superior performance in terms of nitrogen oxides (NOx) and particulate matter (PM) emissions when compared to conventional diesel engine. However, this advantage does not hold at low load operating…
In this study, natural gas and diesel dual-fuel combustion in a heavy-duty compression ignition engine is experimentally evaluated by adopting a modified multi-angle nozzle of a diesel injector to reduce the global warming impact (GWI) factor while…
In the presented work, methods of formation and combustion of solid carbon particles in the cylinder of a piston ICE are considered. The presence of these particles in the exhaust gases has an extremely adverse effect on the environmental situation…
The present study integrated the electrokinetic (EK) with bioremediation (Bioelectrokinetic -BEK) of diesel hydrocarbon by Staphylococcus epidermidis EVR4. It was identified as efficient biosurfactant producing bacteria and growth parameters was…
Natural gas/diesel dual-fuel (NDDF) engine technology is an interesting concept for decreasing greenhouse gas (GHG) emissions of heavy-duty diesel engines. One of the main limitations of this concept is the emissions of unburned methane which is…
In this paper, by coupling a D19 diesel engine three-dimensional and one-dimensional models with a diesel/NG dual-fuel chemical dynamics mechanism, respectively, the thermal and chemical effects of the EGR major components (CO2 and H2O) on…
A gram-negative bacterial strain capable of resisting hexavalent chromium was isolated and evaluated for its characteristics. The strain was designated as Stenotrophomonas acidaminiphila 4-1 according to the 16S rDNA sequence and phylogenic analysis.…
Oil palm is the largest source of livelihoods and vegetable oil consumption to most rural households of developing economies in Asia, Africa, and South America. The heavy reliance on fossil-fuel-based energy in palm oil production raises national…
The use of biowaste feedstock is often suggested for sustainable production of synthetic fuels through gasification followed by the Fischer-Tropsch process. While the technical performance of this type of bioenergy system has significantly been…
Fuel prices are commonly perceived to be excessively high, which regularly triggers political discussions about fuel price regulations. Consumers demand stricter fuel price regulations to provide transparency about the current price level and to…
This paper examines the effects of the number of active COVID19 cases on the wholesale prices of diesel and unleaded petrol (gasoline) across seven Australian states using daily data from 1 Jan 2020–11 September 2020. Our results indicate that…
The detection and quantification of water droplets dispersed in hydrocarbon liquids is of importance industrially, but most notably for quality assurance of products such as diesel and jet fuel. In the present work, a small-scale prototype…
