the aluminum oxide materials are widely used in ceramics, refractories and abrasives due to their hardness, chemical inertness, high melting point, non-volatility and resistance to oxidation and corrosion. the paper describes work done on synthesis of α-alumina by using the simple, non-expensive solution combustion method using glycine as fuel.aluminum oxide (al2o3) nanoparticles were synthesiz...

Future internal combustion engine technologies require an accurate combustion monitoring and control. This can be performed through high frequency recordings of cylinder pressure. However, this solution is limited by the sensor cost and reliability. Another method consist in reconstructing combustion related variables from indirect measurements. In this paper, we propose a combustion indicator ...

Single phase Mn0.8Zn0.2Fe2O4 powders were synthesized by solution combustion method. The solution combustion method relies on the exothermic self-sustained reactions in reactive solution containing of oxidizers and organic fuels. In this work, the effects of various amounts of glycine as fuel on the powder characteristics were investigated. The structure, cation distribution, microstructure, ma...

boron carbide is one of the hardest materials. the combustion method was used to synthesize b4c-tib2 nanocomposite powder in a b2o3-mg-tio2-c system. an experimental study of the formation of b4c–tib2 nanoparticles was conducted in the thermal explosion mode. a mixture of b2o3:tio2:mg:c at a molecular ratio of 3:1:12:1 was chosen to obtain the b4c–tib2. this powder mixture was milled for differ...

Ways to reduce nitrogen oxide emissions In order to comply with the increasingly tough emission standards worldwide, engine manufacturers are forced not only to substantially reduce emissions of particulate matter (PM), but also emissions of nitrogen oxides. The main approach pursued by MTU is low-emission combustion, in other words an internal engine solution. However, this means taking into a...

In order to comply with the increasingly tough emission standards worldwide, engine manufacturers are forced not only to substantially reduce emissions of particulate matter (PM), but also emissions of nitrogen oxides. The main approach pursued by MTU is low-emission combustion, in other words an internal engine solution. However, this means taking into account a basic principle that governs th...

In this study a procedure for sample digestion based on sample combustion assisted by microwave radiation is proposed. Combustion is started by microwave radiation in the presence of oxygen under pressure using ammonium nitrate as aid for ignition. The system was adapted in a microwave oven with quartz closed vessels. A quartz piece is used simultaneously as a sample holder and as protection to...

The present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. Soot concentrations inside the combustor are measured by filter paper technique. The simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and...
