Book excerpt: Comfortable ride is one of the main index of comfortable vehicle and engine mount plays important role in it. Automobile industries are in need of reducing the vibration forces to satisfy customer requirements. Vibration of car engine arises from unbalanced forces of engine, which are transmitted from engine to chassis, and road-induced vibration which is controlled by using proper engine mounts and suspension system. The purpose of this thesis is to study the vibration of automobile engine. Engine mount with elastomeric and hydraulic mounts are developed. Their performance evaluated using bond graph on entire frequency range. Engine mount parameters are optimized by using bond graph optimization method. Sources of engine excitation forces are identified. Engine reciprocating and rotating parts contribute in generating vertical excitation forces. Mounts characteristics are analyzed by their excitation frequency and amplitude. Hydraulic engine mount are more effective than rubber mount because their frequency and amplitude response is superior. Fluid analysis is more complex so linear models and theory on two degree of freedom is developed in this thesis. Presently companies are more concern about customer satisfaction in automobile industries. Passenger may get more comfort if vibration induced due to uneven road or engine is reduced. Selection of proper engine mount, location and optimization of mounts' parameter as per application is required. Force transmitted to passengers needs to be reduced. In this thesis, I applied knowledge from my curricular courses like vibration technology and computer aided design of dynamic system, which helped me to build bond and block diagram of whole powertrain system. I used software CAMPG, Matlab, Mathematica and Nastran to optimize parameter. Hydraulic engine mounts can be made more effective by varying the inertia area and stiffness parameter. They can operate on wide frequency range by varying stiffness using inertia area. Transmissibility is reduced which enables more comfortable ride.

Available in PDF, EPUB and Kindle. Book excerpt: Engine mounting is one of the important components in a vehicle to isolate noise and vibration generated by the engine from the driver and passenger. There are three main types of engine mounting such as passive engine mounting, semi-active engine mounting and active engine mounting. The price of the mounting in the market range from the cheapest which is passive engine mounting to the most expensive type of engine mounting which is the active engine mounting. The effectiveness of the engine mounting vary with the price of the engine mounting with the passive engine mounting being the low quality isolation of noise, vibration and harshness (NVH) and the active engine mounting being the highest quality isolation of NVH. In order to reduce the vibrations, noise and harshness (NVH) level for vehicles, understanding about the vibration characteristics of the passive engine mounting in detail is crucial. The objective of this project is to analyze the vibration cause by the engine of a Perodua Kenari on the engine mounting system at different engine revolutions per minute (rpm). The experiment is carried out on a stationary vehicle using DasyLab software. Here, analysis on the vibration obtained from the experiment carried out helps to determine the time response and frequency response of the engine at different rpm. From the results obtained, we can understand the characteristics of the passive engine mounting which is the fundamental of engine mounting among the three types. By understanding the characteristics of the passive engine mounting, improvement can be made on the engine mounting in a low cost method to further improve on the NVH isolation quality.

Available in PDF, EPUB and Kindle. Book excerpt: The engine excitation forces, arising from gas pressure and unbalance force, are widely considered among the main vibration sources for the road vehicles. Even though the current engine mount designs are acceptable for vibration isolation of the transmitted forces from engine to chassis, the performance improvement of the engine mounting system is still required for the tendency of light weight and higher power of the vehicle. In this thesis, a coupled three degree-of-freedom engine mount system with both elastomeric and hydraulic mounts, are developed. The system performance is evaluated through simulation with the purpose of isolating the vibrations in entire frequency range and under engine excitation force. The engine dynamic model is established based on the analysis of the kinematics and dynamics of its components and gas variation. The unbalanced inertia force caused by engine reciprocating and rotating parts is derived as the vertical excitation force. The net torque, generated by the inertia forces and gas pressure, is formulated using geometrical relationship of the engine components. Two types of individual mounts, including a nonlinear elastomeric mount and a flexible chamber hydraulic mount, are selected from the reported work. The validation of their characteristics is implemented in a single degree-of-freedom (SDOF) system with the response carried out in the time and frequency domain.

Book excerpt: The light-duty vehicle fleet is expected to undergo substantial technological changes over the next several decades. New powertrain designs, alternative fuels, advanced materials and significant changes to the vehicle body are being driven by increasingly stringent fuel economy and greenhouse gas emission standards. By the end of the next decade, cars and light-duty trucks will be more fuel efficient, weigh less, emit less air pollutants, have more safety features, and will be more expensive to purchase relative to current vehicles. Though the gasoline-powered spark ignition engine will continue to be the dominant powertrain configuration even through 2030, such vehicles will be equipped with advanced technologies, materials, electronics and controls, and aerodynamics. And by 2030, the deployment of alternative methods to propel and fuel vehicles and alternative modes of transportation, including autonomous vehicles, will be well underway. What are these new technologies - how will they work, and will some technologies be more effective than others? Written to inform The United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) Corporate Average Fuel Economy (CAFE) and greenhouse gas (GHG) emission standards, this new report from the National Research Council is a technical evaluation of costs, benefits, and implementation issues of fuel reduction technologies for next-generation light-duty vehicles. Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles estimates the cost, potential efficiency improvements, and barriers to commercial deployment of technologies that might be employed from 2020 to 2030. This report describes these promising technologies and makes recommendations for their inclusion on the list of technologies applicable for the 2017-2025 CAFE standards.

This book was released on 2011 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engine mount is an automotive component that is essential in supporting the engine static state in order to prevent engine bounce from shock excitation and to isolate engine vibration caused by engine disturbances in the complete speed range. The main objective of this study is to analyze the dynamic properties which are the natural frequencies and modeshapes of different types of passive engine mounts. In this study, four passive (rubber) engine mount models were considered. The modal analysis were computed by using finite element software, ABAQUS and the results obtained were the modeshapes of the engine mounts. Modeshapes are the deflection shapes taken on by a system when excited at one of its natural frequencies. The corresponding modeshapes of all the rubber engine mount models were computed both in presence and absence of the engine's weight and the results are compared with the results from impact test which has been conducted to one of the engine mount. The computer simulated model of these mounts was analyzed and later the effect of the load applied on the engine mounts were compared with the engine mounts without the load. The results from the modal analysis demonstrated variety in the natural frequency values for all types of passive engine mounts. The modeshapes results showed the trend of bending mode, torsion mode and also the mixture of both. From the modehshapes results, the most deformed spot in the engine mounts can be identified. The results showed that the engine mounting with more metal contact will have the highest frequency of 987.56 Hz when analyzed without the engine weight while the engine mount with less metal contact will have the highest frequency of 1456.20 Hz when analyzed with the engine weight. This shows that rubber engine mounts with the least metal contact design had the highest frequency value of all and this signifies that it can provide the best damper for the engine weight. As a conclusion, the natural frequency of the passive engine mount depends strongly on the applied load although theoretically the natural frequency of a system should not be affected by the applied load. The variations happen because of the rubber viscoelastic nature. Besides that, the natural frequency of the rubber engine mounts also depend on their designs as the least metal contact design showed higher natural frequency value. The results of this study will open up a passage to researchers to study and improve the elastomeric engine mounts.

Available in PDF, EPUB and Kindle. Book excerpt: For the last century, the automotive industry has been dominated by internal combustion engines. Their flexibility of application, driving range, performance and sporty characteristics has resulted in several generations of this technology and has formed generations of engineers. But that is not the end of the story. Stricter legislation and increased environmental awareness have resulted in the development of new powertrain technologies in addition and parallel to the highly optimized internal combustion engine. Hybrid powertrains systems, pure battery electric systems and fuel cell systems, in conjunction with a diverse range of applications, have increased the spectrum of powertrain technologies. Furthermore, automated driving together with intelligent and highly connected systems are changing the way to get from A to B. Not only is the interaction of all these new technologies challenging, but also several different disciplines have to collaborate intensively in order for new powertrain systems to be successfully developed. These new technologies and the resulting challenges lead to an increase in system complexity. Approaches such as systems engineering are necessary to manage this complexity. To show how systems engineering manages the increasing complexity of modern powertrain systems, by providing processes, methods, organizational aspects and tools, this book has been structured into five parts. Starting with Challenges for Powertrain Development, which describes automotive-related challenges at different levels of the system hierarchy and from different point of views. The book then continues with the core part, Systems Engineering, in which all the basics of systems engineering, model-based systems engineering, and their related processes, methods, tools, and organizational matters are described. A special focus is placed on important standards and the human factor. The third part, Automotive Powertrain Systems Engineering Approach, puts the fundamentals of systems engineering into practice by adding the automotive context. This part focuses on system development and also considers the interactions to hardware and software development. Several approaches and methods are presented based on systems engineering philosophy. Part four, Powertrain Development Case Studies, adds the practical point of view by providing a range of case studies on powertrain system level and on powertrain element level and discusses the development of hybrid powertrain, internal combustion engines, e-drives, transmissions, batteries and fuel cell systems. Two case studies on a vehicle level are also presented. The final part, Outlook, considers the development of systems engineering itself with particular focus on information communication technologies. Even though this book covers systems engineering from an automotive perspective, many of the challenges, fundamental principles, conclusions and outlooks can be applied to other domains too. Therefore, this book is not only relevant for automotive engineers and students, but also for specialists in scientific and industrial positions in other domains and anyone who has to cope with the challenge of successfully developing complex systems with a large number of collaborating disciplines.

Book excerpt: Various combinations of commercially available technologies could greatly reduce fuel consumption in passenger cars, sport-utility vehicles, minivans, and other light-duty vehicles without compromising vehicle performance or safety. Assessment of Technologies for Improving Light Duty Vehicle Fuel Economy estimates the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition diesel, and hybrid. According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29 percent at an additional cost of $2,200 to the consumer. Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37 percent at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43 percent at an increase of $6,000 per vehicle. The book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. In contrast, fuel economy measures how far a vehicle will travel with a gallon of fuel. Because fuel consumption data indicate money saved on fuel purchases and reductions in carbon dioxide emissions, the book finds that vehicle stickers should provide consumers with fuel consumption data in addition to fuel economy information.
