M.Tech. Project Details Title : Estimation & Reduction Of Pressure Drop In-Intake System Of A TCIC Engine. Using CFD

Methodology

Project Guides : S KRISHNAN, TML

Key Words : Intake System, CFD, Pressure Drop Abstract - The intake system, which supplies the cylinder with the required amount of air pressure and temperature, is one of the critical systems. Various components are modified and added to the intake system to either get the required pressure and temperature. Modification of these components may affect the pressure in the intake system, which in turn affects the airflow rate and volumetric efficiency of the engine. The present paper addresses estimation and reduction of pressure drop in system through a series of design changes for pipe bending radius & cross section area of pipe, inlet & outlet of the air filter. It discusses about significant time induction using parametric approach-in-Pro-E’(Modeling), Gambit (Grid Generation), Fluent (Analysis). It also discusses the method to determine inertial resistance and viscous resistance factors required to simulate the air filter. The design of intake system is vital for the optimal performance of an Internal Combustion Engine. This paper will present 3D Simulation of a 3.0L CRDI Engine Intake system by using the fluent software and the results are discussed. Steady state simulations have been accomplished for this case. The simulation results are compared with actual vehicle Intake flow for validation. Boundary condition for steady state simulation was obtained from test bench. Finally according to the results of steady state simulations, some suggestions are recommended to improve the performance of this Intake system.

M.Tech. Project Details Title : Combustion optimization of DI Diesel Engine using DOE

Project Guides : Dr. K. C. Vora, Mr. N. H. Walke

Key Words : Combustion Optimization, Design of Experiments

Abstract : “Euro IV is already been implemented in Europe and India is implementing BS IV norms to be effective from 2010. With advanced technologies like high-pressure injection, cooled EGR, combustion process optimization, etc in conjunction with development of 2nd generation common rail injection systems, very low emission levels can be achieved. Additionally the adaptation of the combustion process, for instance the optimization of the piston bowl has shown a huge potential.

In the initial phase of the project a different options of piston bowl geometry to achieve Euro IV were designed with respect to base bowl. The next part of the project deals with Analysis Of Engine Performance Using GT Power, where the test engine design values were inputted and performance under different cases was studied.

An attempt was made to simulate multiple injections using different combustion model.

Even with best optimization if the targets are not achieved then after treatment devices could be necessary. Therefore contribution was made in finalizing the appropriate designs for after treatment devices suitable to our test engine, which is elaborated in this project.

Optimization of diesel engine parameters has become extremely complex, because the recent technology engines have too many parameters and their interactions, which play significant role in controlling emissions. Therefore a Appropriate Designing of Experiments is necessary to reduce time, cost, and energy in understand the complete behavior of the engine. Hence DoE concept was formulated in order to apply this to optimize engine/combustion process.”

Title : OPTIMIZATION OF REGULATOR LPR for CNG application

Project Guides : Dr. S.S.Thipse, Mr. Subramaniam

Key Words : LPR,Wiker wire,Diaphram

Abstract - During the course of this project emphasis was on optimization of the critical components associated with the low-pressure regulator (LPR). The need for this work was felt because LPR is a critical component associated with the CNG system and if it is not up to the mark then it will affect the LPR performance of the engine in terms of idling, power and finally emissions. In doing an optimization, calibration of LPR according to the specifications allows us to decide its suitability and the best result that can be achieved with the frozen design parameters.

Title : PARAMETRIC STUDY AND DESIGN OF HEAD LAMP

Project Guides : Mr. B.V.Shamsundara- ARAI Guide

Key Words :

Abstract - Virtual design methodology is developed to minimize the glare and improving forward visibility. A series expansion of Monte Carlo function is used to represent the ray tracing. A determination of this type (efficient model/revaluation approach) significantly increases the design possibilities when optimization techniques are implemented. As a benchmarking exercise, this novel methodology was practically validated for a parabolic reflector. The Parabolic reflector model was optimized according to the AIS and ECE standards of-points B50R and 75L where carefully handled while optimizing respective reflector in the models. A maximum potential light intensity reduction of the required regions was obtained at the second order surface modeling of the parabolic reflector as a full scale animation of the efficacy of the proposed design method, light rays response from 0.4 Lux lowest to 12 Lux highest light intensity on various zone on the plots are referred to the hot zone horizontal cut line, delta zone, diffusion on different types of reflector shapes. The virtual design method results obtained are compared with another designed segmented reflector. The virtual design methodology uses spine surfaces segments to optimization and reverse ray tracing techniques are used in the simulation to determine optimal illumination on various zones on the road light ray characteristics.

M.Tech. Project Details Title : Development of in-house torsional vibration measurement technique and its application

on vehicle. Project Guides : Mr Mansinh Kumbhar, Mr Prashant.S.Mahale, Dr.K.P.Vivek Shanmuganathan Key Words : Torsional vibrations, gear rattle, natural frequencies Abstract - Gear Rattle is a repetitive metallic impact or rapping noise which occurs on a manual transmission Power train when the vehicle is lugging in gear. The rattle noise intensity generally increases with transmission operating temperature and engine torque, and decreases with increasing vehicle speed. Since the gear ratios have been designed to achieve maximum fuel economy, there may be instances when gear rattle is distinctly noticeable under lugging conditions. Gear rattle is a serious issue concerned to NVH sound quality in vehicles. The major parameters which influence the rattle is speed fluctuation of the rotating elements. The twist in the rotational components is also governed by the tensional frequencies of these components. This issue lead to the project titled “Development of in-house torsional vibration measurement technique and its application on vehicle”In this project a test rig has been designed and developed for validating analytical and experimental methods for determination of torsional natural frequencies. Impact and operational measurements are conducted on the test rig. This experiment provided ground support for further implementation of this method on vehicle level torsional measurements. On vehicle level, torsional natural frequency of the engine components like damper pulley and crankshaft is determined following the method developed on the test rig. After determination of the frequency, a detailed analysis has been carried out of twist and natural frequencies across the clutch as a part of vehicle driveline. Clutch is the main system which is designed to help decouple transmission from engine during speed change but also in addition this system acts as a torsional damper in order to reduce the amplitude of torsional fluctuations generated by engine and is getting transferred to transmission. These torsional variations entering the gear box, which in turn is the cause for gear rattle phenomena.

M.Tech. Project Details Title : Specific Fuel Consumption Improvement by Reducing Frictional Losses

Project Guides : R. Rajgopal Raghavan (M&M), N. H. Walke (ARAI), Vivekanantha Shanmuganathan & Geetha Manivasagam (VIT)

Key Words : SFC, Frictional Losses

Abstract - This project deals with the attempt to improve / reduce the specific fuel consumption (SFC) by reducing the frictional losses of an engine. Reducing specific fuel consumption is almost directly linked to reducing frictional losses, although it is dependent on other factors also. Reducing frictional losses has a distinct positive effect on fuel consumption, i.e. fuel consumption is definitely lowered with reduction in frictional losses. And reducing frictional losses is one of the best ways to lower the specific fuel consumption, since it has no fallouts, as in the case of improving the combustion reactions, wherein it increases some particular exhaust emissions. This project was performed on one of the tractor engine models of the company, which was a torque upgraded engine, i.e., max. torque and max. power / rated speed were higher on this model than its base model, due to which frictional losses were also slightly on the higher side. For determining the frictional losses, a Willan’s Line & a Morse Test were conducted and for identifying the component level frictional losses, a Strip - Motoring Test was conducted.

Project Guide : Mr P.G.Bhat, ARAI

Key Words : Bowl shape,pip

Abstract - “The engine development centres around the world work tirelessly to extract more power from each drop of fuel used so that they can increase the fuel efficiency and at the same time increase specific power capacity of their engines while meeting the ever stringent emission norms. Combustion optimisation becomes the need of the hour. The important parts of the DI diesel combustion system are the intake air system, fuel delivery system and the combustion bowl. The importance and design of the combustion bowl is discussed in this thesis. An overview is provided to the other features of the combustion system namely the fuel injection system and intake ports. The factors that play an important role in the performance of the combustion bowl are identified. These factors include throat diameter, bowl diameter, pip inclination, toroidal radius etc. A case study is done on an experiment carried out on a diesel engine with two different bowls designs. The factors that brought about the differences in emissions and performance values of the two bowls are explained. Also a test case is taken where the engine is to be optimised for meeting the latest emission norms. A bowl design is proposed for optimisation along with the necessary justification attained after extensive literature survey and correlation with the first case study.”

Project Details Title : Conversion of CI engine to operate on CNG - Project at Mahindra FES, Mumbai Project Guides : Mr.Abhay Ganla (M&M, FES), Dr.S.S Thipse (ARAI, EDL) Key Words : CNG, Engine redesign, calibration, Combustion development Abstract - The project was aimed at converting a base diesel engine to operate on CNG. With the rising costs of fossil fuels. The need was felt that in the near future when the availability of CNG would be widespread there would be a market for CNG powered tractors and generators. The basic goal was to achieve the conversion on a tight financial constraint as the customer would not be willing to accept an increase in cost of the engine by more than 10%. Base engine was a 4 cylinder direct injection diesel producing 37Hp@1500 rpm. The project involved redesigning some key engine components such as the cylinder head, pistons and development of new parts such as bracketaries and supports that would support the additional CNG components. Major redesign was concentrated on the piston as the compression ratio needed to be changed to suit CNG operation. Though there existed no emission norms with regars to generator engines, it was decided to meet the current diesel norms that were in effect. Additional electrical components were selected and installed to construct the ignition system of the engine. Care was taken to source these parts and parts already in production on SI gasoline engines were used in order to keep costs down. Once the design stage was completed, a series of prototypes were built and underwent testing at the FES R&D facility in Mumbai. Certain performance and emission tests were also conducted at ARAI with the help of the EDL dept. To achieve emission and performance targets, different CNG kits and configurations were used before finalizing a suitable system. combustion development consisted of running several configurations changing spark plugs, Catalytic convertor loading ratios and changes in ignition timing. Finally emission was achieved (BS 3) for generator engines and also a 55% fuel consumption reduction as opposed to running the engine on conventional diesel

Project Guides : DR. Mahesh Babu/ Mr. Ravindra Mahajan, M&M HoD/Guide Key Words : CRDI, LCV, Bowl, Emission

Abstract - Introduction of Common Rail Direct injection systems in Indian passenger car Segment started with luxury cars. Slowly, the technology spread to the, over economic vehicle segment and was well received by ever cost conscious Indian Customer. This change in trend prompted carmakers to introducer and more of this advanced technology. Even though the technology was considered to be expensive at the beginning, with increasing quantity, the cost became affordable. It is high time that the Indian goods transport and mass transportation segment also receives the advantages and comforts of common rail system. The advantages arise in terms of faster transportation along with longer life of the system, saving time and money. The 2.6L, four cylinder engine develops 80hp of power at the rated 3200 rpm. The torque output of the engine is 206 N -m @ 1800 - 2200 rpm. A high pressure pump and a solenoid valve injector form a part of the common rail system. The main objective of this project was to develop this engine to meet the latest BSIII emission regulations and to applicant the engine for specific light commercial vehicle usage. During combustion development, a large matrix of various types of hardware such as different through flow injectors, turbochargers of different spring stiffness and turbine housing diameters and a couple of piston bowl design were selected and put to test. Apart from changing the hardware components, the combustion parameters such as main injection timing, usage of pilot injection, separation between the pilot and main injection, variation in boost pressure and airflow were also varied to observe their effects on emissions and performance of the engine. After experimental trials, it was concluded that a larger toroidal radius and a shallow bowl is better for emission reduction. A lesser through flow nozzle helps in achieving better emission results.

Project Details Title : Parametric Study Of Inlet Port Using CFD Project Guides : Mr .M.G. Gavali/Mr .A. V .Su b barao, ARAI Guides Key Words : Inlet Port, CFD Abstract - The volumetric efficiency of an engine depends on its breathing capacity, which is nothing but the amount of air taken by the engine through the intake port. Moreover for achieving the present and upcoming stringent emission norms, the perfonllance of the intake port plays an important role. This show~ tl1e importance of the intake port, so design of an intake port plays a major role in an engine design, development and optimization, as it controls the power developed, fuels consumed and exhaust emission from the engine. So for a better performance of a fluid motion inside the engine, which is obtained by using a helical port, as it has great influence on different parameters of engine performance. As the intake port ‘has so much importance, it should be designed in a précised manner, such a way its performance is as desired. And also, it is not easy to design a helical port as vary (;ms parameters has to be considered for its performance and the space constraints in the engine cylinder head, such as the coolant jacket passage, head bolt guides etc., To make of intake port more easy, it is better to go for the parametric modeling, where by changing one important parameter of the model will change all other dimension)al parameters as per the parametric relation given during modeling. For the parametric modeling, some of the influencing parameters of the helical port were identified from the - literatures and by conducting experiments over the available models. It is found that some of the most influencing parameters are throat height, throat radius, helix radius, helical height, cross sectional area etc, The designed model is transferred to the simulation analysis software for analyzing the flow performance of the helical port. The analysis results from the software are validated with the experimental results, which were obtained by developing a prototype for the designed helical port. The conclusions were made based on comparison results.

Title : REDUCTION OF NOISE IN PASSENGER COMPARTMENT OF A VEHICLE

Project Guides : Mr. Uday Senapati, Mr. Prashant Mahale & Dr. Richard Mondal

Key Words : Noise

Abstract - The project was undertaken as a continuous improvement of the vehicle. In one of the car, the scope of improvement in the passenger cabin noise was identified. Sound pressure levels were measured inside the passenger compartment at the driver’s ear position and the rear passenger’s ear position, on rough road at high speed. These measurements reveal that the tyre road noise is dominant. The vibrations generated by tyre road interaction are transferred to body structure through suspension mounts and acoustic cavities of passenger compartment, which is perceived as interior noise. The vehicle was bench marked with the competitor vehicle. The approach implemented to tackle this problem was to attack the transfer paths of the noise, thereby reducing the effect experienced within the passenger compartment. This was achieved by the use of absorbing material, pillar filler material, structural damping and sealing of leakage paths, which were identified to contribute to the transfer of noise in passenger compartment.

Key Words : Catalyst, DOC, Life, Emission Abstract - “Global environment has brought in significant measures for reducing pollution by upgrading engines and vehicles with new technologies and. aftertreatment devices. As diesel engines will continue to playa major role in automotive powertrains for years to come, upgradation & life estimation of after-treatment devices have become necessary to protect the environment over the full life of the vehicle. Extensive research is in progress to improve the after-treatment system, so as to meet the emission requirements over a longer period to meet the expected life. In view of packaging constraint, most of the passenger cars have under body DOC which is prone for choking when exposed to typical Indian city driving conditions due to . The fme soot particles that come out of the engine gets accumulated in the ceramic substrate due to higher cell density, lower porosity of substrate and absence of regeneration strategy. . The exhaust temperature, light off temperature & Exhaust Gas Recirculation (EGR) during the city driving condition has a greater effect on choking of Diesel Oxidation Catalyst (DOC).oisoning of Diesel Oxidation Catalyst due to adulterated fuel and engine additives contribute to choking of DOC. In order to investigate this early failure, an experimental cycle was devised to simulate choking of catalytic converter (in field) on an engine dynamometer and validated with vehicle running on road & emission tests on chassis dynamometer.

Based on these requirements every country formulates their own set of requirements and certification process for validating a product. For exporting the vehicle to a particular country the vehicle manufacturer has to satisfy these requirements. The present report performs a gap analysis of the Indian Automotive standards with respect to the Chinese Automotive standards for a M1 category vehicle, suggests the modifications required in the components, Identifies the mandatory homologation tests and explains the automotive certification process for China. This was done by studying the component level and vehicle level requirements of both China and India. It was found that the Chinese requirements are less stringent than the Indian requirements; but due to the CCC-Mark (China Compulsory Certification Mark) requirement it is difficult to get the certification The test requirements of Wind screen Wiping system, Side Door, Fuel tank, Head restraints, Seating Systems, Seat Belts, Manufacturers Plate, Acceleration control System, Mounting & Position of the License plates, Windshield Defroster and Windshield Demister are different and these components may need to be modified to meet the Chinese requirements. China has an industrial policy of 40% localization there for completely built units cannot be exported to China; hence to enter Chinese market Joint Ventures with other Chinese companies is required. Also the economic policies like separate dealerships for locally made cars and imported cars for the same companies’ makes it difficult for the automobile manufacturers to import completely built units. The emission & safety norms in China are less stringent than in India and there is a huge requirement of utility vehicle due to their climatic & geographical condition; so China can be a good market to enter despite its vicious economic policy.

Title : Study Of Lean Burn And Stoichiometric Combustion Approach For CNG Engines

Project Guides : Dr S.S. Thipse ARAI Guide

Key Words : Lean Bum, Stoichiometric Combustion

Abstract - In this project study on both lean bum and stoichiometric combustion approach was studied by optimizing the engine parameters to achieve improved engine performance and to get emission results with in BS III emission norms. Natural gas is an excellent engine fuel. Its combustion and emission characteristics are superior to any other realistic competing fuel. Natural gas has a high cetane number which prevents its operation in a compression ignition cycle (the cetane number is a measure of a fuel’s ignition delay in a compression-ignition test). The compression ratio (CR) of the typical diesel engine, when converted directly to spark ignition operation, is also high to operate on natural gas without knock renewable in nature, obtained from diverse sources, economically cheaper, safer burning fuel with higher octane rating. The lean bum combustion has higher efficiency; higher BMEP- potential, reduced thermal load and heat rejection. The stoichiometric combustion has low emissions with slnall combustion variability.

M.Tech. Project Details Title : Fan Noise Prediction & it’s Experimental Validation Project Guides : S.Raju, Krishan Chugh & V A Tandon Key Words : Fan Noise, AeroAcoustics Abstract : “Fan noise is a problem in many domestic and industrial applications, such as for cooling and ventilation, and its solution would go a long way to enhance the acoustic quality of machinery or product competitiveness. Fan noise can be divided into discrete tones related to rotational speed of the fan, and broadband noise. The latter is caused by turbulent flow conditions, which may or may not be attributable to design or operation. Tonal noise arises from many possible sources; such as high steady flow loading, unsteady flow caused by the interaction of rotor and stator/strut, or intrinsic unsteady flow condition such as vortex shedding from structures. Requirement for quieter and more efficient fan systems to improve the automotive thermal and acoustic characteristics has lead to development of a methodology to numerically simulate the fan system. Experimental sound measurement is quite straightforward however; analyzing the origin of noise remains elusive. A review of literature available on the prediction of noise performance of fan using computational techniques is presented. The present study thus focuses on the prediction of fan noise using CFD and validating it experimentally as per ISO 13347-Part 4. An anechoic chamber measurement technique is used to determine the fan noise characteristics. Sound power level is determined by using sound intensity measurements on a measurement surface, which encloses the sound source. Both steady state and transient analysis were carried out to predict the noise generated by the fan. Steady state analysis predicts discrete tones and is computationally less expensive. On the other hand transient analysis predicts discrete as well as broadband characteristics accurately, but at higher computational expense. The flow velocities and sound pressure levels were predicted and the results were experimentally validated. The study showed that the steady state analysis could be useful for the comparison of various designs. The transient analysis can be useful for the detailed analysis of fan noise characteristics and its optimization.“

Title : Noise Assesment of Diesel Engines

Project Guides : P.S.Mahale

Key Words : Engine Noise, source contribution

Abstract - In recent years, due to the influence of strengthened exterior vehicle noise regulations and growing awareness for comfort, strong requirements have come up for reduction of engine noise. Therefore, it is important to understand various noise sources and its contributions to engine noise, which are the basic requirement for finding possibilities for engine noise reduction. Five diesel engines of different categories of vehicles, namely three wheeler, passenger car, multi utility vehicle (MUV), Agriculture tractor, and heavy commercial vehicle (HCV) were assessed in terms of noise. All five engines are evaluated for variation of noise with load and speed to arrive at worst case condition in terms of noise emission. Overall sound power level (SWL) varies between 98 dB (A) (for midsize car) to 104 dB (A) (Agriculture tractor). Also, Spectrum of SWL remains flat between 800 Hz to 4000 Hz which is due to structure borne noise generation. Noise source identification is carried out on all five engines to find major noise sources. Methodology used for noise source identification deals with sound intensity mapping supported by noise and vibration measurement. It is observed that major noise sources are crankcase, cylinder head, tappet cover, oil sump, intake and exhaust. Many efforts had gone to reduce contributions of these components to overall noise levels. But as these contributions goes down, accessories like fuel pump, turbocharger, cooling fan shows dominance. Therefore, it is concluded that all these accessories require attention to reduce noise.

Project Guide : Mr. Mahesh A. Patwardhan, ARAI & Mr. G. Venkataramanan, FORCE MOTORS LTD

Key Words : Powertrain, NVH, Data Acquisition

Abstract- “NVH represents an important quality feature of today’s automobiles. In order to offer the customer the best possible product, it is essential to include NVH optimization in the development process from the start of concept phase to the production phase. A vital factor in meeting demanding NVH targets is the right design of the power train mounting system. Power train suspension system design is a compromise between isolation of the vehicle from power train vibration and constraining the motion of the power train within vehicle packaging and handling targets. Engine is one of the major sources of vibration in a vehicle. The vibrations from the engine originate from the Dynamics of reciprocating and rotating masses (Inertia forces) and also from combustion process (Gas Pressure). The chassis needs to be isolated from such engine vibrations without harming the installation / life / ride. This project is intended 1. To develop a methodology for systematic design, development and evaluation of mounting system for 4 strokes, 4 cylinder inline diesel engines. 2. A particular case study of a HCV where the power packs, chassis are already designed is presented here. The mounting selection being vital needs to eliminate transfer of vibrations/shocks of the running engine. The designed supports needs to withstand the dynamic loading requirements of the vehicle at various combinations of suspension, road and engine characteristics.3. The required analysis will be carried out by using commercially available multi body dynamic simulation package and the results will be validated experimentally.“
