Honda's October 2015 R&D Technical Review features cutting-edge developments and new ways of solving engineering problems from Honda's worldwide R&D teams. This edition brings 14 technical papers covering: • Gasoline engine brake thermal efficiency • Development of new turbocharged diesel engine for Honda CR-V • Downsizing as evolution of high thermal efficiency gasoline engine • Emission reduction technology using secondary air for generator engine • Development of new H2 refueling method for FCV to reduce refueling time • Development of transmission-mounted transmission control unit
Whirl flutter is the aeroelastic phenomenon caused by the coupling of aircraft propeller aerodynamic forces and the gyroscopic forces of the rotating masses (propeller, gas turbine engine rotor). It may occur on the turboprop, tilt-prop-rotor or rotorcraft aircraft structures. Whirl Flutter of Turboprop Aircraft Structures explores the whirl flutter phenomenon, including theoretical and practical as well as analytical and experimental aspects of the matter. The first introductory part gives a general overview regarding aeroelasticity, followed by the physical principle and the occurrence of whirl flutter in aerospace practice. The next section deals with experiment research including earlier activities performed, particularly from the sixties, as well as recent developments. Subsequent chapters discuss analytical methods such as basic and advanced linear models, and non-linear and CFD based methods.
Conventional fossil fuels will constitute the majority of automotive fuels for the foreseeable future but will have to adapt to changes in engine technology. Unconventional transport fuels such as biofuels, gas-to-liquid fuels, compressed natural gas, and liquid petroleum gas will also play a role. Hydrogen might be a viable transport fuel if it overcomes barriers in production, transport, storage, and safety and/or if fuel cells become viable. This book opens by considering these issues and then introduces practical transport fuels. A chapter on engine deposits follows, which is an important practical topic about how fuels affect engines that is not usually considered in other books. The next three chapters discuss auto-ignition phenomena in engines. The auto-ignition resistance of fuels is the most important fuel property since it limits the efficiency of spark ignition engines and determines the performance of compression ignition engines.
Revised and extended, this new edition provides the foundation for diesel engines design, based on traditional methods in thermodynamics, dynamics, structural analysis, chemistry, heat transfer, and applied analysis of system operation. It also offers additional material and examples for the calculation of combustion process, thermal efficiency, heat release, NOx emissions, and diesel turbocharging. Diesel Engine Engineering-2nd Edition demonstrates operating processes with detailed graphs and schematic diagrams, illustrates the characteristics and modes of diesel engine operation, describes the thermodynamics parameters and emissions of a working cycle, discusses how various design factors affect the system reliability, offering correct techniques to improve stability and endurance. Main areas of technical expertise include: • Diesel Engine Turbocharging • Automated Control of Diesel Engines • Thermodynamics of Diesel Engines
Tribology and Dynamics of Engine and Powertrain: Fundamentals, Applications and Future Trends provides an authoritative and comprehensive overview of the disciplines of dynamics and tribology using a multi-physics and multi-scale approach to improve automotive engine and powertrain technology. The book reviews the fundamental aspects of the physics of motion, particularly the multi-body approach to multi-physics, multi-scale problem solving in tribology. Fundamental issues in tribology are described in detail, from surface phenomena in thin-film tribology, to impact dynamics, fluid film and elasto-hydrodynamic lubrication means of measurement and evaluation. It also includes many aspects of the physics of motion at a multitude of interaction scales from large displacement dynamics to noise and vibration tribology, all of which affect engines and powertrains.
Engine combustion pressure analysis is a fundamental measurement technique applied universally in the research and development of reciprocating combustion engines. As combustion pressure measurement systems have become almost standard equipment in engine test environments, technicians and engineers need to have a solid understanding of this technique and the associated equipment. This book provides practical information on measuring, analyzing, and qualifying combustion data, as well as details on hardware and software requirements and system components. Describing the principles of a successful combustion measurement process, the book will enable technicians and engineers to efficiently generate the required data to complete their development tasks.
