Background/Objectives: Gear measurement is an important as well as critical step and it is done in bench centers by using instruments which have a gear with mandrel. However, this method is found to be time consuming. In addition it is very difficult to execute this process without additional man power. Methods/Statistical Analysis: In the existing method of measurement using bench centers includes a surface table which contains head, dead center. In this proposed measuring machine we introduced a digital dial indicator arrangement to measure whole depth of the gears. Findings: It reduces the measuring time as well as man power required. In this proposed research work, an attempt has been made to reduce the time taken in measuring the whole depth, face out and run out in gears from 10 minutes to 7 minutes that is 30% reduction. Application/Improvements: Thus proposed method would be well matches for modern gear manufacturing industries to obtain micron level measurement in terms of time as well as man power consumption.Keywords

Background/Objectives: The major pollutant that comes out from engine exhaust of Diesel Power Plant (DPP) is Nitrogen Oxide (NOx)as well as Sulphur oxides (SOx). Since NOx concentration level is higher it affects our environment to great extent. Our main objective of our project is to reduce NOx concentration level to lower rate of parts per million (ppm). Methods/Statistical Analysis: The NOx concentration level is higher in DPP as they didn’t install any NOx control methods. We suggested using Selective Catalytic Reduction (SCR) method for controlling NOx emission. Ammonia (NH3) is making use of reagent in SCR technique and it is inject to the exhaust stream. Findings: NH3 reacts with NOx present in the exhaust and it is converted into Nitrogen (N2) and water (H2O). It is proposed that, if SCR system is installed in Diesel Power Plant, NOx concentration level is expected to reduce from 1100 ppm to 132 ppm. Application/Improvements: If The proposed system is implemented successfully in the power plant, then NOx concentration level could be reduced to approximately 132ppm (<2 g / kWh).

Background/Objectives: Cooling system of the engine is one of main essential systems for automobiles, which maintains the engine temperature to the sustain conditions. Hence the main objective of this project work is to propose a simple piping design with less number of connecting hoses and also to reduce coolant leakage. It is also proposed to change the piping material from aluminium alloy to mild steel which reduces the overall cost of the engine cooling system. Findings: The proposed design addresses the coolant leakage problem and reduces the number of parts used in coolant pipe connections hence leading to cost reduction and simplified design. Application/Improvements: The proposed design would benefit with coolant leakage elimination by reduction in hose defects, reduced head loss, cost reduction and improved life of piping system in automobiles heavy vehicles.

Background/Objectives: Engine produces high amount of heat while running. This can raise the engine temperature to very high level and can damage or seize the engine components. Hence for the safety of engine components, it needs to run at much lower temperature, which is called engine working temperature. Methods/Statistical Analysis: Radiator plays a vital role in engine cooling system. When increasing the cooling efficiency of radiator causes increase the life time of engine. The efficiency of the radiator can be increased by changing the surface area or dimension of the tube or increasing the number of fins/tubes. The heat transfer rate for the existing radiator could be analyzed. Findings: After analyzing the existing radiator, the new radiator has been designed. Two flat plates are placing inside the tube which acts as the nozzle. Hence, nozzle velocity increases and pressure decreases. Pressure is directly proportional to temperature. Application/ Improvements: Thus, the temperature of coolant inside the radiator decreases. As a result efficiency of the proposed radiator is increased 5.37% when comparing with existing method.Keywords
