Abstract:
The project titled “Design and Analysis of an IC Engine Piston” focuses on developing an optimized piston design for an internal combustion (IC) engine through advanced modelling and simulation techniques. The piston is a critical component subjected to extreme mechanical and thermal loads during engine operation, making its design and material selection essential for ensuring durability and performance. The project begins with the conceptual design of the piston using SolidWorks software, incorporating standard design parameters such as bore diameter, stroke length, and compression ratio. Finite Element Analysis (FEA) is then used to evaluate the structural integrity of the piston under thermal and mechanical stresses during the combustion cycle. The analysis includes stress distribution and deformation to identify potential failure zones. Material selection is also considered, comparing conventional aluminium alloys with advanced materials such as reinforced composites to enhance strength and heat dissipation. Design modifications, including optimization of piston geometry and weight reduction, are implemented to improve engine efficiency and reduce wear. The results of the analysis provide insights into improving piston durability and performance, contributing to the development of more efficient and reliable IC engines. This study offers a comprehensive approach to enhancing the design lifecycle of engine pistons by integrating simulation, material science, and mechanical analysis Keywords: stress distribution, deformation, potential failure zones

Abstract In this research, our focus centers on investigating the stress distribution across various piston materials employed in internal combustion (IC) engines. Recognizing the pivotal role of the piston as a critical and intricate component within the engine, its sustained optimal condition is imperative to ensure the engine’s proper functionality. Mechanical stress emerges as a primary factor leading to piston failure. Consequently, our study delves into the analysis of mechanical stress exhibited by different piston materials, aiming to gain insights into their performance under various conditions. The exploration of stress distribution across diverse materials contributes valuable information for enhancing the durability and reliability of pistons, thereby advancing the overall efficiency and longevity of IC engines.

Abstract:
The piston is considered as most important part of I.C engine. High temperature produced in an I.C engine may contribute to high thermal stresses. Without appropriate heat transfer mechanism, the piston crown would operate ineffectively which reduce life cycle of piston and hence mechanical efficiency of engine. The literature survey shows that ideal piston consumes heat produced by burnt gases resulting in decrease of Engine overall Efficiency. In this project work an attempt is made to redesign piston crown using TBC on piston surface and to study its Performance. A 150 cc engine is considered and TBC material with different thickness is coated on the piston. 3D modeling of the piston geometry is done 3D designing software Solidworks2015. Finite Element analysis is used to calculate temperature and heat flux distribution on piston crown. The result shows TBC as a coating on piston crown surface reduces the heat transfer rate within the piston and that will results in increase of engine efficiency. Results also show that temperature and heat flux decreases with increase in coating thickness of YSZ.

Abstract:
Internal combustion engines in now a days is the best available reliable source of power for all domestic, large scale industrial and transportation applications. The major issue arises at the efficiency of these engines. Every attempt made to improve these engines tends to attain the maximum efficiency. The performances of the diesel engines are enhanced by proper design of inlet manifold, exhaust manifold, combustion chamber, piston etc. The study is about the effect of piston configurations on in- cylinder flow. Here a single cylinder direct injection diesel engine is used for study. For obtaining swirl intensity helical-spiral combination inlet manifold is used. Increase in swirl intensity results in better mixing of fuel and air. Swirl Velocities in the charge can be substantially increased during compression by suitable design of the piston. In the present work, a study on the effect of different piston configuration on air motion and turbulence inside the cylinder of a Direct Injection (DI) diesel is carried out using Computational Fluid Dynamics (CFD) code Fluent 16.0. Three dimensional models of the manifolds, pistons and the cylinder is created in CATIA V5 and meshed using the pre-processor ANSA v15.1.1.

Abstract:
This paper presents simulation of working process in a new IC engine concept. The main feature of this new IC engine concept is the realization of variable movement of the piston. With this unconventional piston movement it is easy to provide variable compression ratio, variable displacement and combustion during constant volume. These advantages over standard piston mechanism are achieved through synthesis of the two pairs of non-circular gears. Presented mechanism is designed to obtain a specific motion law which provides better fuel consumption of IC engines. For this paper Ricardo/WAVE software was used, which provides a fully integrated treatment of time-dependent fluid dynamics and thermodynamics by means of onedimensional formulation. The results obtained herein include the efficiency characteristic of this new heat engine concept. The results show that combustion during constant volume, variable compression ratio and variable displacement have significant impact on improvement of fuel consumption.

Abstract This research investigates a thermo-mechanical strength of three geometrical shape designs of an internal combustion (IC) engine piston by a finite element analysis (FEA). FEA was performed using Solidworks software for modelling geometrical piston designs, and the models were imported into ANSYS software for thermo-mechanical fatigue simulation. The work focused on predicting high stress intensity and indicated the fatigue critical regions and life of the piston shape design. AL7075-T6 aluminium alloy was used as a piston material and thermo-mechanical fatigue simulation was conducted based on the experimental stress-number of cycles recorded data from literature. Analytical results showed the similarity of the critical failure positions to some real failures in the IC engine piston, and the shape design modification of the piston. Hence, this concept can be used to satisfy the IC engine design needs at low cost.

Abstract:
A zero dimensional model has been used to investigate the combustion performance of a four cylinder petrol engine with unconventional piston motion. The main feature of this new spark ignition (SI) engine concept is the realization of quasi-constant volume (QCV) during combustion process. Presented mechanism is designed to obtain a specific motion law which provides better fuel consumption of internal combustion (IC) engines. These advantages over standard engine are achieved through synthesis of unconventional piston mechanism. The numerical calculation was performed for several cases of different piston mechanism parameters, compression ratio and engine speed. Calculated efficiency and power diagrams are plotted and compared with performance of ordinary SI engine. The results show that combustion during quasi-constant volume has significant impact on improvement of efficiency. The main aim of this paper is to find a proper kinematics parameter of unconventional piston mechanism for most efficient heat addition in SI engines.

Abstract:
This thesis presents research on upward pointing oil jets that provide cooling of downward facing heated surfaces. The specific purpose of this research is to improve understanding of the oil jet cooling of internal combustion engine pistons. In this research, the cooling of heated blocks with flat and concave surfaces was investigated. Temperature measurements were obtained using an array of thermocouples embedded inside the heated blocks. A flash illumination and high resolution CCD camera system was used to observe the liquid jet impingement. Observations identified a 'bell-sheet' flow pattern, jet interference, jet splatter and jet breakup which provided insights into the liquid jet impingement processes normally encountered on downwardfacing surfaces. Bespoke contracting-type nozzles were used to produce the jet flow structure. The data from these nozzles were used to generate new empirical correlations for oil jet cooling of downward-facing flat surfaces and for predicting the size 6f impingement. The results obtained from these tests were also used for comparison with cooling jets from production automotive piston cooling nozzles. The research has demonstrated that the effectiveness of oil jet cooling can be affected by preheating the oil and varying the injector size to alter the targeted cooling efficiency, and liquid loss due to jet breakup and splatter. Local heat transfer coefficients were observed to increase when the jet Reynolds number increased. Piston undercrown cooling was studied using a range of oil jet configurations. The cooling rates improved with optimised targeted jets. The results also indicated that the undercrown geometry designs such as crosshatched surfaces, undercrown-skirt and gudgeon-pin boss, were significant for enhancing the local rate of forced convective heat transfer. New empirical correlations were developed from the experimental results that enabled prediction of the heat transfer coefficient and jet impingement size for high Prandtl number liquid jets impinging onto downward-facing surfaces. The heat transfer correlations were developed for normal (θ = 90°) and inclined (θ = 75°, 60° and 45°) jet impingements.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2007.<br>Officially submitted thesis was in in electronic form.<br>Includes bibliographical references (p. 129-134).<br>Carbonaceous deposits have long plagued the internal combustion engine, yet a fundamental comprehension of their underlying causes remains to be developed. In particular, piston land deposits can bring about an array of problems; for example, once a thickness threshold is crossed, the engine's reliability is threatened by an elevated possibility of seizure. As tightening emissions regulations continue to place more stringent constraints on power cylinder design, control of piston deposits, specifically in the top land and top ring groove, is becoming ever more difficult. Tests run on a heavy duty diesel engine revealed the piston land carbon deposit distribution to be circumferentially nonuniform, and a theoretical inquiry was invoked to investigate the cause. Since these deposits are typically lubricant derived, a three-dimensional, unsteady model of the oil film attached to a piston land was formulated. Focus was placed on the top land, in order to explore the effects of both reciprocating inertia and combustion-driven gas flows on the film's motion and thickness distribution. The numerical simulation created uses results from a realistic CFD simulation of the combustion process as input data. It was found that the gas velocities can have a profound effect. The gases create interesting wave structures on the free surface of the oil film, significantly altering the film thickness distribution. A new mechanism governing oil transport was discovered. Clever usage of this mechanism could substantially reduce the amount of oil, and hence the amount of deposit, on the top land. The simulation shows potential for application not only to the study of deposit formation, but also to that of oil consumption.<br>by Sean McGrogan.<br>S.M.

Abstract:
The reciprocating IC engine plays an important role in the world transport, with very few alternative configurations having commercial success. In light aircraft applications where low vibrations are crucial, boxer engines have predominated. The rising cost of fuel and the growth of public concern over pollutant emissions has led to an increased interest in alternative designs. In recent years, with the uprising of new technologies, research techniques and materials, the OP engine has emerged as a viable alternative to the conventional IC engine in some applications including in the aeronautical field. This study presents a numerical analysis of the combustion process of octane-air mixture in a four-stroke SI opposed piston engine. The model used in the simulations represents the internal volume of the cylinder of UBI/UDI-OPE-BGX286 engine. The simulation was run in Fluent 16.0 software, the species transport model was chosen to model combustion from the available in Fluent, and three different engines speeds were simulated: 2000RPM, 3200RPM and 4000RPM. Regarding the results obtained from the three CFD simulations, the overall behavior and properties of the in-cylinder flow and the obtained graphics were considered acceptable.<br>O motor alternativo de combustão interna desempenha um papel importante no mundo dos transportes, existindo ainda poucas configurações alternativas com sucesso comercial. Relativamente a aplicações em aeronaves ligeiras, onde as baixas vibrações são de extrema importância, os motores boxer têm predominado o mercado. O aumento do custo do combustível e o aumento da preocupação do público com as emissões de poluentes levaram a um maior interesse em novas alternativas. Nos últimos anos, com o surgimento de novas tecnologias, técnicas de pesquisa e materiais, o motor de pistões opostos surgiu como uma alternativa viável ao motor convencional de combustão interna em algumas aplicações, inclusive na área aeronáutica. Este estudo apresenta uma análise numérica do processo de combustão da mistura de octano-ar num motor de faísca a quatro tempos e de pistão oposto. O modelo utilizado nas simulações representa o volume interno do cilindro do motor UBI / UDI-OPE-BGX286. A simulação foi executada no software Fluent 16.0, dos modelos disponíveis no Fluent o modelo de transporte de espécies foi escolhido para modelar a combustão, e três diferentes velocidades de motor foram simuladas: 2000RPM,3200RPM e 4000RPM. Em relação aos resultados obtidos nas três simulações CFD, o comportamento geral e as propriedades do fluxo no cilindro e os gráficos obtidos foram considerados aceitáveis.

Abstract:
The piston of the internal combustion engine is one of the most complex parts among all engine components. During the operation, the pistons of IC engines are typically subjected to high loading and wearing. To withstand these, they require high mechanical properties and excellent tribological properties. This chapter aims to compare the mechanical as well as tribological properties of silica-gel-reinforced aluminium composite with aluminium alloy, which is used in manufacturing of piston of IC engine. Initially silica-gel-reinforced aluminium composite was fabricated with base material aluminium and six different percentages of silica gel reinforcement by stir casting method. After that, mechanical and tribological properties of silica-gel-reinforced aluminium composite were estimated and the tremendous mechanical and tribological properties among all percentages by different optimization techniques were found. The authors then compared the admirable properties of aluminium composite with aluminium alloy for manufacturing of piston of IC engine.

Abstract:
A comprehensive survey of power source choices for helicopter use is presented. Using the University of Maryland helicopter sizing code, several powerplant and drive options including electric batteries, fuel cells, gasoline and diesel powered piston engines, turboshaft engines, electric generators, and electric motors are evaluated for two helicopters: a two-seat 600 kg class helicopter similar to the Robinson R22 (payload of 180 kg and endurance of about 2 hours) and a 1700 kg class helicopter similar to the EC120 (payload of 400 kg and endurance of about 4 hours). Recent developments in diesel and gas turbine powered electric generators (Range Extender) and integrated electric motor-gear boxes are surveyed and evaluated for helicopter use. A survey of electric motors and integrated gear boxes shows the availability of geared electric motors with high specific powers. The objective is that the alternate-powered helicopters should have the same payload, range and endurance capabilities as the baseline helicopters. Parametric studies are conducted with various power sources including IC engines, battery, fuel cell, range extender, integrated electric motor and gear box. These results show that the pure diesel engine option is an attractive fuel efficient option for both helicopters. The diesel hybrid electric option results in a heavier helicopter that has higher fuel consumption. However, all these options have lower take-off weights than the existing baseline helicopters and the hybrid diesel electric option can be a practical lead-in for a pure electric helicopter.

The durability of the Piston can be modelled accurately, only by accounting all the loads acting on the Piston. The challenge is, this approach requires information from multiple disciplines such as temperatures from CFD, Piston secondary forces from Multi-Body Dynamics (MBD) analysis and P-theta (Pressure vs Crank angle) curve from the experimental measurements.

The ring geometry, its assembly load and its mechanical and thermal properties are factors that influence engine performance. The ring dynamics is greatly influenced by piston secondary motions that depend upon the piston geometry, piston pin offset, its center of gravity (C.G.) location and piston-liner clearance. The engine is simulated to study the rings motion in axial, radial direction and the gap areas are calculated to estimate blowby and compared with experimental results. This approach to engine design reduces the conceptual design-to-development cycle time and reduces the need of extensive engine testing for evaluating ring performance.

Abstract:
A mathematical model for cylinder-piston system considering the coupling between dynamic behavior and tribological behavior is presented in this paper. The three-dimensional finite element method is used to compute the engine block vibrations. The lubrication of cylinder-piston pair was described by an average Reynolds equation considering the piston second-vibration and asperity contact of rough surface. The corresponding computing program developed can be used to calculate the engine block vibrations, the entire piston trajectory, the Piston slap forces, friction forces and oil film thickness etc. as functions of crank angle under engine running conditions. The numerical simulation results show that the coupling between engine block dynamical behavior and lubrication has big influence for the secondary motion of piston and the engine block vibration in cylinder-piston system. It is essential to consider the engine block vibration in the analysis of cylinder-piston tribology.

Abstract:
&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Internal combustion engine (IC engine) vehicles are commonly used for transportation due to their versatility. Due to this, efficiency in design process of IC engines is critical for the industry. To assess performance capabilities of an IC engine, thermal predictions are of utmost consequence. This study describes a computational method based on unsteady Reynolds-averaged Navier–Stokes equations that resolves the gas–liquid interface to examine the unsteady single phase/multiphase flow and heat transfer in a 4-cylinder Inline (i-4) engine. The study considers all important parts of the engine i.e., pistons, cylinder liners, head, block etc. The study highlights the ease of capturing complex and intricate flow paths with a robust mesh generation tool in combination with a robust high-fidelity interface capturing VOF (Volume-of-Fluid) scheme to resolve the gas-liquid interfaces. Results obtained show the dominant processes that determine the oil distribution to be the piston speeds from reciprocating motion of the pistons and the flow rate of oil injected through the squirter jets. A novel heat transfer approach (mixed time-scale coupling) is used to solve for the temperatures in the engine solids. To resolve the heat transfer between the squirter jet flow and piston/cylinder liner, the approach separates the conjugate heat transfer calculation into a fluid heat simulation and a solid heat simulation while setting up a communication method to exchange the thermal boundary conditions between them. The communication method takes into account the changes in heat transfer from piston to cylinder liner due to changes in position of the piston. The study also considers water jacket cooling in the engine block and head to holistically assess the overall heat transfer in the engine solids. Results of thermal simulation show the solid temperatures to be in direct correlation with the oil distribution near those solids as well as the flow rate of water coolant in water jacket cooling system.&lt;/div&gt;&lt;/div&gt;

Abstract:
This paper presents the computational analysis of piston ring wear and oil consumption for an internal combustion (IC) engine. Two computational models, piston-ring wear and oil consumption, are employed to simulate the results for this analysis. Both instantaneous and transient results are discussed. The piston-ring wear model, namely WEAR, is built on the fundamentals of mechanical and adhesive wear mechanism; while the oil consumption, namely OILCONSUME, is on the fundamentals of oil vaporization and upper-ring gap oil reverse flow mechanisms. The two models are integrated with two external engine simulators: the Ford Motor Company General Engine SIMulation (GESIM) of the Ford Motor Company, and the Cylinder kit Analysis System for Engines (CASE) of the Michigan State University Engine Research Laboratory. An objective of this analysis is to understand how the engine operation condition impacts the piston-ring wear and the oil consumption per engine cycle basis. Also, it is to understand how the piston-ring wear affects the oil consumption and other engine mechanisms on a long time basis. A virtual Ford 4.6L-V8 engine has been tested on various engine speeds and loads to produce the computational results. The results show that the engine load and the engine speed play significant roles, individually and collectively, on the engine performance. The results also show the dependence of the oil consumption and the blow-by on the piston-ring wear over long-time engine run. The instantaneous and transient simulations have provided useful insights on the relation between the piston-ring wear and the oil consumption mechanisms in an IC engine.

Abstract:
In specific speed and load ranges mechanical noise excitation contributes significantly to the overall noise of an internal combustion (IC) engine. Piston slap induced noise is a very important mechanical noise source. As the second part of two sequential papers, this contribution describes the numerical simulation of the structure noise of an entire IC engine. The findings for the cylinder kit models in part I are considered specifically. The mathematical model for an elasto-hydrodynamic contact of piston skirt and liner wall in a mixed lubrication regime is applied to a fully coupled simulation of the entire engine block vibration. The contribution of piston slap excitation is evaluated against other sources of excitation, like crankshaft dynamics and combustion gas pressure. Measurements of the engine block surface accelerations are performed in fired conditions and are compared to the results obtained by the simulation. It is shown how noise sources in the piston cylinder kit are transferred to the engine block surface structure. The paper demonstrates the reliability of a comprehensive model for engine noise simulation in the development process for future engine designs.
