“Implementation of throttle- by-wire control for a vehicle”
Prof. Jadhav S.S.M.E. Mechanical (Heat Power) S.G.P. Shrigonda.
ABSTRACT : In a throttle-by-wire car, a microcontroller determines the correct throttle plate position. Electronic control of this plate offers improved fuel economy and economy by maintaining optimal throttle positions at all times, which otherwise is not humanly possible. The electronic throttle controller uses a physical sensor to read the throttle plate angle. The physical sensor is a circuit which uses a potentiometer to modify the output voltage of the sensor based on throttle plate angle. In this model throttle plate angle is input and a signal representing the voltage is output. The controller in this system is required to convert its output into a standard pulse width modulated signal (PWM). The electronic throttle body opens and closes the throttle plate valve, which controls the amount of air inducted into the system.

Analysis on Performance Characteristics and Emissions of Diesel Engine using different Blends of Calophyllum Inophyllum, Cotton Seed Oil, Karanja.
Prof. Kale M.G. M.E. Mechanical (Heat Power) S.G.P. Shrigonda.
ABSTRACT : Ecological concernment and energy extremity of the planet has led to the quest of feasible alternatives to the non-renewable fuel source, FAME (Fatty Acid Methyl Ester) is biodegradable, ecological, alternative, and safe, environmental friendly which has a high flash point and is also termed as Bio-Diesel. In upcoming years, in most of the regions of the world production and application of biodiesel has extrinsic fame. It is usually produced by the method trans-esterification. In this experiment, biodiesel from Calophyllum Inophyllum oil, Karanja Oil Methyl Ester and Cottonseed Oil has been produced using the trans-esterification process. Engine trail have been executed in water cooled, 4- stroke diesel engine. Investigational analysis has been conducted to study the performance and emission on different biodiesel blends of Cottonseed Oil, Karanja Oil Methyl Ester and Calophyllum Inophyllum oil for unequal injection pressures. From the evaluation of obtained results, it can be deduced that the engine operation process is considerably become better with noteworthy subdual in emissions of the CO and HC.

Weight and shape optimization of engine mounting by using topology optimization.
Prof. Kundlik Gajanan Jagtap M.E. Mechanical (Machine Design) S.G.P. Shrigonda.
ABSTRACT : Engine mountings are widely used in automotive to hold Engine with chassis. Automobile industry regularly improving from many years with the efforts in modification of the mechanical parts of vehicle in order to improve their performance. The most effective way of increasing automobile mileage while decreasing emissions is to reduce vehicle weight. Existing mount has scope of mass optimization in current design. Finite element analysis of mounting will be done using Hyper mesh and Ansys. Ansys software will be used for topology optimization. Fixture will be designed for mounting bracket on UTM. Experimental stress of mount will be measured using strain gauge and applying corresponding loading through UTM. Validation for strain vector from FEA & Experimental results will be done. Conclusions and future scope will be suggested. After this testing of mild steel material we are comparing it with composite material.

Stress and Deflection Analysis of Cultivator Hitch T-Joint Under Tensile And Bending Loading.
Prof. Gore P.M. M.E. Mechanical (Machine Design) S.G.P. Shrigonda.
ABSTRACT : Welded joints are widely found in almost all applications like construction structures, automotive, agricultural equipment’s (cultivator hitch joints) and many more applications. Tensile, bending, torsional and multi axial loads act on cultivator hitch welding joints during operations. Joints are used for various member coming together at same location joints behavior at tensile and bending loading are investigated.Catia V5software is used for modeling is used for modeling T joint of standard dimension. Discretization(meshing) and finite elements analysis is carried out using ANSYS package joints is welded with holding fixture for carrying out experimental analysis.
Experimental stress analysis is carried out using strain gauge for measuring strain values and UTM for applying gradual loads. Loads of similar values were applied on T joint in tensile and bending manner.
Results were validated by comparative analysis using FEA and strain gauge values. Experimental and FEA correlation was in linear relation. It was concluded that T joints are stronger in tensile as compared to that of bending loading conditions.

“Design, Testing and Performance Analysis Of E-Bike”.
Prof. Darekar D.S. M.E. Mechanical (Heat Power) S.G.P. Shrigonda.
ABSTRACT : The electric vehicles industry is continuously evolving. One type of such electric vehicle is the electric bicycle (e-bike). Electric bicycles, like other electric vehicles, use a BLDC motor (Brushless Direct Current Motor). This report presents a way of designing and implementing an electronic module for an e-Bike. The main aim of this report is to present the idea of harnessing the various energy and use it in today’s existence of human life. For human being travelling has become vital. In order to sustain in this fast forward world he must travel from place to place. It is very important that time taking for travelling should be less, also it should be economical and easily available.
