Design and Experimental Validation of Intake System to Improve Performance of Race Car[ ]


The design of induction system play vital role to optimize the engine performance. The objective of this work is to design induction system for race car as per requirement of 20mm restrictor, which limits the generated power. This concept has been developed to achieve the homogeneous flow into the cylinders in four stroke four cylinder Engine and separate plenums used to prevent the overlapping. In this design dual plenum used for the intake system which incorporates with the throttle valve and venture to reduce the pressure difference and improve the engine performance, inertial wave charging and resonance peak is achieved by optimizing the runner length. The modeling of system is done in Pro-E and simulation is carried out by using ANSYS Fluent software. Based on computational result, the protype is fabricated and validated with experimental & simulation data. The result shows that the use of dual plenum helps to maintain the uniform flow into the cylinders, increases the engine power and optimum pressure drop.

Influence of Cryogenic Processing on Microstructure and Properties of En8 Steel[ ]


En8 steel is most commonly used steel in applications like gears, bolts, pins, studs, etc. These applications of En8 material requires it to be readily machinable and at the same time posses sufficiently high amount of hardness and strength. Conventional heat treatment process that is used to enhance the mechanical properties of En8 steel consists of quenching and tempering. Cryogenic processing consists of quenching the material, then treating it at temperature as low as –193°C., followed by tempering of material. The existing literature confirms that cryogenic processing results in enhancement of mechanical properties of tool steel. Current study deals with finding out how effective is cryogenic processing for enhancing the harndess and impact strength of En8 material as compared to conventional heat treatment process.

A study to understand differential equations applied to aerodynamics using CFD Technique[ ]


The purpose of this paper is to study the methodology involved in Computational Fluid Dynamics (CFD) technique of fluid flow.Computational fluid dynamic results are directly analogous to wind tunnel results obtained in a laboratory they both represent sets of data for given flow configuration at different Mach numbers, Reynold numbers, etc. The cornerstone of computational fluid dynamics is the fundamental governing equations of fluid dynamics i.e. the continuity, momentum and energy equations. These equations speak physics. The purpose of this study is to discuss these equations for aerodynamics. In CFD the fundamental physical principles applied to a model of flow can be expressed in terms of basic mathemati-cal equation which are either Integral equation or partial differential equation. In the world of CFD, the various forms of the equations are of vital interest. In turn, it is important to derive these equations in order to point out their differences and similarities, and to reflect on possible implications in their appli-cation to CFD. An example of application of CFD to aerodynamics is discussed in this paper. Finally, post-processing and interpreting the result com-pletes the methodology.

Heat Generation and temperature in Orthogonal Machining[ ]


Heat generation during metal cutting process is of particular importance as it governs machining mechanisam and thus the economy of machining. The high temperature adversely affects the strength, hardness and wears resistance of the cut-ting tool. Excessive heat generation in cutting zone causes dimensional changes in the part being machined and can induce thermal damage to the machined surface. Temperature at tool-chip and tool-workpiece interfaces influences tool wear, tool life and surface integrity. Tool–chip contact length can be a critical parameter in machining as it provides the path for heat flow from the secondary deformation zone into the tool. Therefore, reducing the amount of heat flowing into the cutting tool is of great significance. In all, it is very important to study the heat generation mechanisam, heat partition and temperature distribu-tion in machining processes. The paper reviewed the heat generation and effects and control of temperature rise in metal ma-chining.

NANO FUELS: EFFECTIVE ALTERNATIVE TO DIESEL FOR CI ENGINE[ ]


Central objective of this review paper is to encapsulate findings to have viable alternative to diesel as main working medium in Compression Ignition Engine. Various investigations on biodiesel were succeeded in order to diminish burden on consumption of diesel but due to lesser thermal efficiency and emission characteristic of divers blends could not achieve at par results with neat diesel. Advancement in Nano-technology and successful results of Nano particle in varied fields seek attention of researchers and engineers to include Nano particle in diesel blending. This study represents overview and results on experimental investigation to examine the effect of Nano additives on diesel engine performance at variable operating conditions of loads and speeds. Use of Cerium Oxide, Alumina Oxide, Carbon nano tube and other are used for experimentation. Water emulsion blends also tested with neat diesel and nano fuels. Advertently it can be seen that improvement in brake thermal efficiency (BTE) is increased by 1-2%. Reduction in major pollutant such as NOx, CO, HC has been achieved. Brake specific fuel consumption (BSFC) was reduced by marginal amount.

Fabrication of Pendulum Pump[ ]


This paper discusses the importance of a pendulum pump which can be used as a supplementary device for pumping water and is made to replace hand pumps. One important feature of a pump with a pendulum is that the work is alleviated or in simple terms it makes work rather easier when is compared with a traditional hand water pump. It is due to this underlined feature which enables the pendulum pump to be used as an efficient mode in the irrigation of smaller lots, water-wells and can also be used in extinguishing fires even by old people and children. By the use of pendulum based water pumping system we can increase the efficiency of the plant and reduce the effort, cost of production, production time, manpower requirement.

Regenerative Braking Systems (RBS)[ ]


Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed as all the energy here is being distributed in the form of heat. Regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Driving an automobile involves many braking events, due to which higher energy losses takes place, with greater potential savings. With buses, taxis, delivery vans and so on there is even more potential for economy.
