Recently, the research interest regarding ammonia applications in energy systems has been increasing. Ammonia is an important hydrogen carrier that can also be obtained starting from renewable sources. Furthermore, used as a carbon-free fuel combustion systems. In particular, behavior of internal engines (ICEs), fueled by ammonia, needs to further investigated. The main disadvantage this kind i...

Abstract The demand of powertrain technologies able to efficiently employ several non-fossil fuels types, as bio or synthetic ones, compels develop simplified strategies accelerate the engines industrial optimization. High-tumble ultra-lean SI are currently an attractive option, thanks their fuel flexibility and potential extending lean combustion limit with novel ignition strategies. This work...

in this study, the geometries of the [sininhn]q and [sicunhn]q clusters, (n = 4,5,6 and q = 0,+1,-1) complexes have been optimized to form complexes with four, five and six planar and nonplanarsubstituents, with negative, neutral or positive atomic charge, using density functionaltheory (dft) at b3lyp/6-311+g (3df, p) computational level and then their thermodynamicstability were investigated b...

Hydrogen is a carbon-free fuel that can be produced in many ways starting from different sources. Its use as internal combustion engines could method of significantly reducing their environmental impact. In spark-ignition (SI) engines, lean hydrogen–air mixtures burnt. When gaseous like hydrogen port-injected an SI engine, working with mixtures, supercharging becomes very useful order not to ex...

Diesel engine combustion becomes very rough and can lead even to deflagration under high altitude conditions, which is harmful component durability. In this study, the effects of on main characteristics—in-cylinder fluid flow, spray behavior, pressure temperature distribution—were analyzed with CFD. A numerical model was built CONVERGE platform validated optical behavior trace measured by test ...

The increasing industrialization and motorization of the world has led to a step rise for the demand of petroleum-based fuels. Petroleum-based fuels are obtained from limited reserves. These finite reserves are highly concentrated in certain regions of the world. Therefore, those countries not having these resources are facing energy/foreign exchange crisis, mainly due to the import of crude pe...
