A review on influence of different flushing methods on Material Removal Rate using EDM.

2019-11-21
2019-28-2543
Electrical release machining (EDM), is a material removal procedure whereby a coveted shape is acquired by utilizing electrical releases (sparks). Material is expelled from the work piece by a progression of quickly repeating current releases between cathode and anode, isolated by a dielectric fluid and subject to an electric voltage. At the point when the voltage between the two terminals is expanded, the power of the electric field in the volume between the anodes winds up more prominent than the quality of the dielectric (in any event in a few spots), which separates, enabling current to stream between the two cathodes. This wonder is the equivalent as the breakdown of a capacitor (condenser). Accordingly, material is expelled from the cathodes.

Automobile Exhaust Emmision Control- A review

2019-11-21
2019-28-2382
Since the 20th century increase in the number of cars in the major cities is been a point of concern because of the toxic gasses being emitted from the engine of an automobile. These gasses are polluting the atmosphere and degrading the air to breathe. The main gasses responsible for the degradation of air quality are carbon monoxide, hydrocarbon and oxides of nitrogen. There is a necessity to find ways to reduce the pollution emitted into the atmosphere from the automobile. The source of emission is either evaporation from fuel tank or carburetor which is easy to be dealt with or harmful gasses due to improper combustion which is a concern for the environment. The two ways to reduce these emissions are, modification in the engine to minimize the production of harmful gases and to treat the harmful gasses emitted from the engine before blowing it into the atmosphere from the exhaust. Catalysts help to break harmful gasses into smaller compounds that are environment-friendly.

2019-28-2467
Engineering objective Light Electric Vehicles (LEV) with Li-ion batteries suffer from short battery life and poor efficiency, due to low grade electronics. Battery management systems (BMS) cannot always keep the pack in balance, and after cell voltages drift, capacity of the pack diminishes and some cells may destruct, causing a fire. The paper describes a novel approach to LEV powertrains using parallel connected battery cells & control methodology that keep cells in balance naturally, thereby eliminating BMS and hence safer to use. Li-Ion cells with different chemistries can be used and superior thermal management reduces temperature rise, resulting in longer battery life. Methodology Based on the original invention by the author, the system circuit schematics was designed and simulated using OrCAD PSpice. After obtaining results from the simulation, the first prototype device was constructed and tested in laboratory.
