Abstract:
This paper presents the structure and static model of engine camshaft analysis. For the purposes of this analysis, the finite element method is used. Camshaft is one of the critical components for effective and precise work of internal combustion engines. This camshaft rotates at high speed causing pressure and vibration in the system. Camshafts are also subject to varying fatigue burden due to cam plunger contact. These precise values are required to be determined to prevent failure in the camshaft. The objective of the project is to model and to perform pressure analysis on the camshaft machine. In this project the standard engine camshafts are modeled and analyzed using the CATIA V5R21 software respectively. This model is created by the basic requirements of the engine. It is done with an existing background, such as the power of acting on cam by means of a valve while running at maximum speed. Here the approach becomes fully CAE based. CAE-based approaches enrich Research and limit the time span. A study was conducted to predict the behavior of the different camshafts structure of the material using the finite three-dimensional pressure of the element. Four types of materials such as Steel, Titanium, Aluminum and Magnesium are taken into account. FEA Stress and maximum displacement decisions are calculated and compared to all of the above materials. The conclusion is to focus on the material suitable for the camshaft to reduce the maximum displacement and weight. Titanium materials become the best material for camshaft manufacturing based on analysis.

Abstract:
A key functional aspect of assembled camshafts is the joining strength between the shaft tube and the cam lobe, which is depended on the assembly or joining method. The assembly process by knurling joining and torque deformation of assembled camshaft were numerically studied and the key influencing factors on the press fit load and joining strength were analyzed. The experiments including to the press fit and torque strength of lobe/tube joining were carried out.The results show that the torque strength of the cam lobe/shaft joining can availably increase by matching cam and tube materials, choosing appropriate knurling form, enlarging magnitude of interference and extending knurling width. The numerical results agree well with the experiments and are significant in the design and manufacture of assembled camshaft.

Abstract:
Along with the development of internal combustion engines, camshafts have also been developed to optimize engine performance. In all types of internal combustion engines, the crankshaft is connected to the camshaft via a toothed belt, chain or pinion. When the crankshaft turns, the camshaft spins and opens and closes the intake and exhaust valve respectively. However, in this non-camshaft engine technology, each intake and exhaust valve will be integrated with an electronically controlled hydraulic pump unit. This system provides a unique ability to independently control intake and exhaust valves. For any engine load, load and discharge times can be programmed independently. The decision system is based on driving conditions, used to maximize performance or minimize fuel consumption and emissions. This allows a greater degree of control over the engine which in turn provides significant performance benefits. This article presents reviews of camshaftless technology developed by VALEO. It is a system that uses solenoid valves to open and close the valve. The solenoid valve will be mounted right on top of the valve inside the engine. The author can see that the technology using this electronic control valve will help reduce the fuel consumption of the engine.

Abstract:
In the present study, ductile iron camshafts low alloyed with 0.2 and 0.3 wt % vanadium were produced to study the microstructural and mechanical evaluation of lobes and camshaft. For this purpose, camshafts were produced in one of the largest manufacturers of the ductile iron camshaft in México by the phenolic urethane no-bake sand mold casting method. The microstructure of the lobes was studied in three zones located at the top, middle, and bottom of the lobes by optical microscopy, and mechanical tests were performed on lobes and camshafts. A homogeneous distribution of spheroidal graphite with high nodularity for both castings was obtained from the regions of the lobes analyzed. The high cooling rate on the lobe surfaces enabled us to obtain a high nodule count of a smaller size instead of the middle region where big nodules with a low nodule count are presented. An inverse chill behavior was found in the middle region of the lobes where there is an increase in the concentration of carbide-forming elements, leading to the highest micro-hardness values in this region. The tensile properties were increased when the vanadium contents were increased; however, the toughness and ductility of the as-cast alloys were decreased as a result of the increase of the volume fraction of carbide particles.

Abstract:
Finite Element Method based techniques apply to a wide spectrum of engineering applications including manufacturing. The flexibility to achieve optimized results by simulations adds another dimension to process-development. The efficiency due to simulation is enhanced many folds for developing desired components by reducing the cost as well as time. This paper investigates cold forging process to be adopted to produce camshafts with a target to minimize flash as well as under filling. These two factors being major problems encountered when cold forging is to be adopted for complex shaped products. The current work is primarily concerned with the development of an optimized preform design for a V8 engine camshaft. The work involved the Solid modeling of the camshaft on AutoCAD and further analyzing the developed model through finite element analysis using Deform 3D. The analysis involved understanding of metal flow, volumetric analysis and die stresses in the forging process. The materials considered for the work-piece and the dies are AISI 8620 and AISI-H-26 respectively. The sample camshaft was taken from a standard Dodge Challenger V8 engine. 10 different cases are analyzed to find out the best possible scenario. It is fund that the stress level for the developed model was very much within the design limit of the material.

Abstract:
Ductile iron camshafts low alloyed with 0.2 and 0.3 wt % vanadium were produced by one of the largest manufacturers of the ductile iron camshafts in México “ARBOMEX S.A de C.V” by a phenolic urethane no-bake sand mold casting method. During functioning, camshafts are subject to bending and torsional stresses, and the lobe surfaces are highly loaded. Thus, high toughness and wear resistance are essential for this component. In this work, two austempering ductile iron heat treatments were evaluated to increase the mechanical properties of tensile strength, hardness, and toughness of the ductile iron camshaft low alloyed with vanadium. The austempering process was held at 265 and 305 °C and austempering times of 30, 60, 90, and 120 min. The volume fraction of high-carbon austenite was determined for the heat treatment conditions by XRD measurements. The ausferritic matrix was determined in 90 min for both austempering temperatures, having a good agreement with the microstructural and hardness evolution as the austempering time increased. The mechanical properties of tensile strength, hardness, and toughness were evaluated from samples obtained from the camshaft and the standard Keel block. The highest mechanical properties were obtained for the austempering heat treatment of 265 °C for 90 min for the ADI containing 0.3 wt % V. The tensile and yield strength were 1200 and 1051 MPa, respectively, while the hardness and the energy impact values were of 47 HRC and 26 J; these values are in the range expected for an ADI grade 3.

Abstract:
Camshafts are crucial components in combustion engines. Their purpose is to control the opening and closing of intake and exhaust valves, which affects various aspects of an engine’s performance. The valves control the intake of the air-fuel mixture in the combustion chamber and the exhaust of combustion gases. The synchronization of this task with the engine’s cycle is essential for the system to work as desired, and timing parameters such as valve duration affect the engine’s power and efficiency. This thesis addresses the development task of a software program for camshaft design. The program must be able to receive input design parameters, process them and provide visual and numerical information for the user to make decisions in the design process. It also needs to be intuitive and provide guidance through a highly iterative process. The program is divided in two parts: cam mechanism and shaft design. The intake and exhaust cams are initially designed in accordance to the desired timing properties of the combustion cycle, the engine speed and the mechanism’s structural properties. They are later included in a shaft with specific structure and dimensions, and its deformations and stresses are analyzed in order to validate the design or back up to a previous step to perform a new iteration. The program is developed entirely in Mathworks Matlab using Matlab’s GUIDE for the GUI design and only standard Matlab libraries. The development method is presented along with the GUI’s description and an application example, using ANSYS to perform a FEM deformation and stress analysis for comparison with the program’s results.
Kamaxlarna är viktiga komponenter i förbränningsmotorer. Deras syfte är att styra öppnandet och stängandet av insugnings-och avgasventiler, som påverkar olika aspekter av motorns prestanda. Ventilerna kontrollerar intaget av luft-bränsleblandningen i förbränningskammaren och förbränningsmotorns avgaser. Synkroniseringen av denna uppgift med motorns cykel är avgörande för systemet drift, och timing parametrar såsom ventil varaktighet påverkar motorns effekt och effektivitet. Denna avhandling behandlar utvecklingen av ett program för kamaxel design. Programmet måste kunna ta emot indataparametrar, bearbeta dem och ge visuell och numerisk information så att användaren kan fatta beslut i designprocessen. Det måste också vara intuitivt och ge vägledning genom en mycket iterativ process. Programmet är uppdelat i två delar: kammekanismen och axelns konstruktion. Insugs-och avgas kammar är ursprungligen tänkta i enlighet med önskade tidsegenskaper för förbränningscykeln, motorvarvtalet och mekanismen strukturella egenskaper. De ingår i en axel med specifik struktur och dimensioner, och dess deformationer och spänningar analyseras i syfte att validera designen eller för att säkerhetskopiera till ett tidigare steg för att utföra en ny iteration. Programmet är utvecklat helt i Mathworks Matlab med Matlab's GUIDE för GUI design och använder bara vanliga Matlab-bibliotek. Den utvecklade Metoden presenteras tillsammans med beskrivning av GUI och ett exempel,som verifieras med hjälp av ANSYS genom att utföra en FEM-baserad deformations och spänningsanalys.

Abstract:
Nondestructive evaluation techniques were employed to fully characterize three 2.3L camshafts tested in an engine simulator for an equivalent of 100,000 miles. Optical microscopy, acoustic microscopy (SAM), and profilometry were used to characterize wear and fatigue, crack depth, and surface roughness, respectively. Results show cracking to occur mainly in the opening ramp of the most abusively ground cam lobes. No clear evidence was found for subsurface cracking at depths as great as 200 mm from the lobe's surface. Profilometry results show no evidence of any major tribological effect due to the sliding friction of the follower. Fractography studies show a difference between fracture surfaces among the cracks examined; straight cracks exhibit features resembling fatigue propagation, while fracture surfaces from pitted cracks show a more brittle behavior. Small grinding cracks (approximately 300 mm in length) were found in the opening ramps of the most abusively ground lobes prior to testing. Knoop and Nanoindenter microhardness indicate a near-surface rehardening for the most abusively ground lobe (confirmed by metallography), and temper burn for the remaining lobes. X-ray residual stress results made in the opening ramp of the tested lobes show evidence of residual stress relaxation. X-ray line width data as a function of depth does not correlate with residual stress.

Full text
Abstract:
The introduction of overhead camshaft valve train systems some 25 years ago has resulted in improved engine performance and efficiency, this in turn however, has caused increased wear problems. In order to understand the tribological behaviour of overhead camshaft systems, test engines and dynameter test methods have been extensively used. These are however, time consuming and expensive, a cheaper and quicker method of camshaft material and lubricant appraisal is therefore required and this has resulted in the design and construction of a simulative overhead camshaft test rig. A range of commercially available camshaft and follower materials have been tested using both a fully formulated and a -mineral base -equivalent. The most commonly encountered cam and follower wear failures of scuffing, pitting and polishing were reproduced. Results showed scuffing wear to be associated with all of the camshaft materials using the mineral base oil under high load, boundary lubrication conditions. Scuffing also occurred under low load, mixed lubrication conditions using the case-hardened steel cam and chilled white iron follower combinations. The remaining cam materials, carbonitrided and induction hardened grey flake iron did not fail under similar test conditions due to the presence of free graphite in the icrostructure. The fully formulated oil generally suppressed the onset of scuffing under all test conditions due to the presence of the zinc-dialkyldithiophosphate (Z.D.D.P) anti-wear additive in the oil. Pitting failure was associated with the chilled white iron follower using the fully formulated oil under high load conditions. This failure could have been initiated by either a surface, sub-surface or stress - corrosion mechanism. Analysis of this type of failure is complicated by the difference in both chill depth and hardness and also the presence. of cracks within, samples prior to examination and testing. Standardisation of chilled white irons therefore needs to be carried out in order to understand fully the wear behaviour of such materials. Polishing wear was associated with the fully formulated oil at low loads, and appeared to occur by a chemical reaction between the contacting surfaces and the additives present in the oil. The use of the acetate replica technique proved a satisfactory method of analysing the change in surface topography of cam surfaces. Using the fully formulated oil the cam surface 'ran in' satisfactorily, by a process of plastic deformation and fracture, whilst the mineral base oil caused instanteous scuffing of the cam surface. Once the surfaces had 'run in' satisfactorily by using either the additives in the oil or by a diamond lapping operation, the cams continued to run without scuffing in the mineral base oil under continuous, non stop test conditions. An intermittent, stop/start operating cycle however results in eventual scuffing due to additive film depletion and repeated surface interaction under boundary lubrication conditions. From a range of 'new' materials tested for follower application the ceramics, with the exception of the toughened zirconia, exhibited the best wear characteristics using a case hardened steel cam as a standard and tested under mineral base oil conditions. The silicon carbide and sialon ceramics both exhibited a low frictional resistance and wear rate, whilst the metallic follower materials of cobalt and nickel base hard facing alloys and a ceramic fibre reinforced aluminium/silicon alloy all suffered some form of material.

Abstract:
The work described in this thesis was carried out to investigate the application of variable valve actuation (VVA) to light-duty diesel engines for use in passenger vehicles. The background to this was that there was little published on the subject and with advanced turbochargers, exhaust gas re-circulation systems and high pressure fuel injection systems reaching maturity it seemed likely that further enhancement of the air management in this type of engine, through VVA would receive greater interest. The first section of this thesis discusses the external pressures on engine manufacturers, from legislation and from the customer expectations, which could be expected to influence the adoption of VVA, while looking at the criteria on which they would assess a VVA system prior to adoption. Section two provides an overview of the effects of VVA and how they may be used to improve engine operation by highlighting the specific features of diesel engines, i.e. cold starting and compression ratio, part load fuel economy, full load torque and transient torque rise, that can be influenced by air management and what characteristics are required from the VVA system in order to provide improvements in these areas. Having identified the key features of a VVA system that would be suitable for use in light duty diesel engines section three presents a brief literature review and discusses the family of non-constant angular velocity VVA systems that were identified as having the correct characteristics and relative simplicity necessary for any system that might be made in high volume production. This section also provides a detailed analysis of one system of this type to highlight its behaviour and impact on valve train design. Software was written to model the selected mechanism and produce the valve lift characteristics for use in simulating the engine's behaviour. Section four provides an overview of engine simulation techniques and some detail of the model constructed for this investigation. It also discusses the additional code and methodologies required to model the turbine, compressor and combustion processes, which required special treatment, and presents data to compare the behaviour of the model with the baseline of known engine behaviour. Section five presents simulation results that show the following possible improvements: a) a 23% increase in torque, b) light part-load fuel economy improvements of 13% and c) transient rise to maximum torque times reduced from 2.3 seconds to 1.6 seconds. It also discusses the features of engine operation with VVA that provide the potential for these improvements in engine operation, quantifies the benefits that might be expected at a large number of operating conditions and discusses the interactions between the VVA and other systems such as the turbo-charger and EGR system. Section six presents conclusions which beside the enumeration of the potential benefits and description of the key effects of VVA, highlights the need for test data to verify the extent to which the benefits can be realised in real engines and suggests areas for future research.

Abstract:
As future downsized boosted engines may employ multiple combustion modes, the goal of the current work is the definition of valving strategies appropriate for moderate to high load spark ignition (SI) combustion and for spark assisted compression ignition (SACI) combustion at low to moderate loads for an engine with variable valve timing capability and fixed camshaft profiles. The dilution and unburned gas temperature requirements for SACI combustion can be markedly different from those of SI; therefore it is important to ensure that a given valving strategy is appropriate for operation within both regimes. This paper compares one dimensional (1D) thermodynamic simulations of rated engine operation with positive valve overlap (PVO) and a baseline negative valve overlap (NVO) camshaft design in a boosted automotive engine with variable valve timing capability. Several peak lifts and valve open durations are investigated to guide the down-selection of camshaft profiles for further evaluation under SACI conditions in a companion paper. While the results of this study are engine specific, rated performance predictions show that the duration of both the intake and exhaust camshafts significantly impacts the ability to achieve high load operation. While it was noted that the flow through the exhaust valve chokes for the majority of the exhaust stroke for peak exhaust lifts less than 8 mm, the engine rating could be achieved with peak intake lifts as low as 4 mm. Therefore, camshafts with peak lifts of 8/4 mm exhaust/intake were down selected to facilitate multimode combustion operation with high levels of PVO. Analysis of high load operation with the down-selected camshafts indicates that peak unburned gas temperatures remain low enough to mitigate end-gas knock, while other variables such as peak cylinder pressure, turbine inlet temperature and turbocharger speed are all predicted to be within acceptable limits.

Abstract:
Abstract The camshaft of a cam-follower mechanism experiences a position-dependent moment due to the force exerted on the cam by the follower, causing the angular speed of the camshaft to fluctuate. In this work, a method to expediently predict the camshaft speed fluctuation is developed. The governing equation of motion is derived assuming that the cam-follower system is an ideal one wherein all members are treated as rigid. An existing closed-form numerical algorithm is used to obtain the steady-state rigid-body dynamic response of a machine system. The solution considers a velocity-dependent moment; specifically, a resisting moment is modeled as a velocity-squared damping. The effects of flywheel size and resisting moment on camshaft speed fluctuation are studied. The results compare favorably with those obtained from transient response using a direct integration scheme. The analytical result also shows excellent agreement with the camshaft speed variation of an experimental cam-follower mechanism. The steady-state rigid-body dynamic response obtained herein also serves as a first approximation to the input camshaft speed variation in the dynamic analysis of flexible cam-follower mechanisms in a subsequent research.

Abstract:
Abstract In this paper we analyze the nonlinear dynamic behavior of an internal exhaust gas recirculation system based on the mean-value model of an experimental engine equipped with a camshaft phaser. We develop a dynamic camshaft timing schedule that regulates the internal exhaust gas recirculation system while maintaining transient engine torque response similar to an engine with zero exhaust gas recirculation. The dynamic schedule consists of a steady-state map of the camshaft timing for optimum exhaust gas recirculation based on throttle position and engine speed, and a first order lag that regulates the transition of the camshaft timing to the optimum point. A scheme for adjusting the time constant of the first order lag depending on engine speed and throttle position is described.

Abstract:
This paper is intended to discuss the optimization of camshaft efficiency; using the rolling bearing instead of the sliding bearing within the internal combustion engines. The advantages and disadvantages of employing this new method will be accordingly identified and determined in-order to open new windows to the vehicle manufacturing industry. Following the mentioned goal; a camshaft is designed and tested over two types of sliding and rolling bearings in the same conditions of testing. After the comparisons being made; the achieved records have been analyzed and finally the results have been concluded and discriminated by the tables. The calculations and analyses; which are reachable within this paper, are implemented by employing both simulation software and laboratory devices.
