Title	:	Analysis of Valve Mechanism – A Review
Country	:	India
Authors	:	A. S. More, S P. Deshmukh

Abstract: The main role of the valve train is to ensure the gases exchange process for all the engine speeds. The valve gear mechanism of an I.C. engine consists of those parts which actuate the inlet and exhaust valves at the required time with respect to the position of piston and crankshaft. The gases exchange process influences the engine good functioning, a kinematic and a dynamic analysis are required for the engine valve train. The vibratory and acoustic behavior of the internal combustion engine is a highly complex one. The engine speed is the most important parameter in valve train dynamics. A flexible multi-body model can be used investigate the dynamic behavior of a valve train by considering the interactions between valve train components i. e. the model includes a flexible camshaft, spring and rocker arm.

Title	:	Thermal Energy Assessment of Indian Cement Plant Specially Related to Rotary Kiln
Country	:	India
Authors	:	R. K. Patil, M. P.Khond, L. G. Navale

Abstract: This work is basically, a modeling of rotary cement kiln where objective is to optimize fuel and air consumption. The study aims to optimize on air and fuel quantities at kiln considering design parameters of the cement plant by keeping adequate safety factors at each level of calculations to assure that neither production rate nor quality of clinker vary. The data obtained from industry show that the first law efficiency and the second law efficiency of the kiln system are 50.41% and 61.39% respectively. Irreversibility of the system was found to be about 20%, which is due to the conversion from chemical to thermal energy. Theoretical energy requirement of this plant is 1720 kJ/kg of clinker whereas actual energy supplied is 2286 kJ/kg of clinker .The energy difference is 566 kJ/kg of clinker. Keeping allowance for losses and unaccounted figure still we can reduce actual supply energy up to 2000 kJ/kg of clinker. The study suggests that there is still scope of energy saving up to 12%. This can be achieved by direct and indirect methods i.e. through air optimization, fuel optimization and reduction of losses through kiln wall. Thermal energy consumption reduces from 3.2 GJ/ton of clinker to 3.0 GJ/ton clinker at J. K. Laxmi. Air consumption reduces from 98 TPH to 88 TPH. It saves electrical consumption upto 17% Thus total thermal and electrical energy saving is quantified in terms of rupees that is coming in the range of rupees 18 to 27 million.

Title	:	Review on Development of Hydrogen CNG Blender Mechanism for Existing Gasoline Engine Vehicles
Country	:	India
Authors	:	K. R. Kapadani, Kavita R. Kapadni

Abstract: With increasing concern about energy shortage and environmental protection, research on reducing exhaust emissions, reducing fuel consumption, reducing engine noise and increasing specific outputs has become the major researching aspect in combustion and engine development. Alternative fuels such as CNG, HCNG, LPG, LNG, bio-diesel, biogas, hydrogen, ethanol, methanol, di-methyl ether, producer gas, p-series have been tried worldwide. Hydrogen and CNG blends (HCNG) may be considered as an automotive fuel without any major modification in the existing gasoline engine and infrastructure. It is observed in the experimental work that the HCNG blends are more superior to gasoline carburetted engines from fuel economy, power output and emission compliance point of view.There is a need to develop and install Hydrogen - CNG blenders in existing gasoline engines for improvement in efficiencies, for reduced fuel costs and for better reliability & operating flexibility of automobile.

Country	:	India
Authors	:	D. R. Marigoudar, S.R.Patil

Abstract: Vehicle Life time is highly determined by the fatigue life of its components. Variability in the material parameters may have a strong effect on the fatigue life. In order to achieve better performances together with improved safety, a new design process is needed to build automotive components, This new process requires shift from traditional design approach to a new approach that incorporates all the variability's and uncertainties in the analysis phase and in the design flow and to use computer simulation methods to guarantee design reliability. This paper gives an overview of the role of fatigue life in design of mechanical components, and the methods to calculate the fatigue life of the different components and its role in on new designs in optimizing the design based on the life of the components[2][3][4][5].

Title	:	Eclipse Drive Train for Windmill
Country	:	India
Authors	:	A. A. Keste, A. A. Tolani, V. A. Handre, N. R. Sharma, M. A. Gavhane

Abstract: The failure of conventional gearbox (constant mesh) is mainly due to shearing of gear teeth in contact, which is eliminated by using kinematic linkages in eclipse gear box. The force which is transmitted from the input shaft to the output shaft, which is mechanically coupled to rotor of the generator, is uniformly and equally distributed by the number of links present in eclipse gear box. The requirement of only one stage instead of multiple stages in conventional gearbox for complete transmission of power improves the reliability of the gearbox. For useful electricity generation constant output shaft speed is required which is achieved by eclipse drive train.

Keywords – Kinematic linkages, Single stage, reliability, Constant output shaft speed.

Title	:	Development of Slip line model For MicroTurning Process
Country	:	India
Authors	:	S. B. Bawaskar , L.G. Navale

Abstract: Micro-turning, the inevitable micro-machining technique is a tool based micro machining process. The applications include use of micro shafts for micro pins, micro motors in the area of robotics, MEMS, biomedical, aerospace etc. The micro- turning process, as it is influenced by the edge radius, both ploughing and shearing occurs while removing the excess material depending up on the feed rate used. The objective of this research is to model the forces involved in the micro-turning process using slip-line field theory by considering the effects of edge radius, ploughing, and the built-up edge (BUE) to account for both ploughing and shearing. Unlike previous models the proposed model describes both the shearing and ploughing process as plastic deformation processes and will includes the effect of the minimum chip thickness and BUE. The ploughing force, the built-up edge and the minimum chip thickness effect which lead to the nonlinearity of the process are described in this model.
