Book Description
Pounder’s Marine Diesel Engines and Gas Turbines, Tenth Edition, gives engineering cadets, marine engineers, ship operators and managers insights into currently available engines and auxiliary equipment and trends for the future. This new edition introduces new engine models that will be most commonly installed in ships over the next decade, as well as the latest legislation and pollutant emissions procedures. Since publication of the last edition in 2009, a number of emission control areas (ECAs) have been established by the International Maritime Organization (IMO) in which exhaust emissions are subject to even more stringent controls. In addition, there are now rules that affect new ships and their emission of CO2 measured as a product of cargo carried. Provides the latest emission control technologies, such as SCR and water scrubbers Contains complete updates of legislation and pollutant emission procedures Includes the latest emission control technologies and expands upon remote monitoring and control of engines
Turbocharging Systems with Control Intervention for Medium Speed Four-stroke Diesel Engines

Book Description
The turbocharging systems of highly boosted four-stroke diesel engines (BMEP 25 bar/363 psi) have to cope with two basic problems: lack of air and compressor surge at reduced engine speed. In the case of medium speed engines for ship propulsion and stationary applications, the following three control interventions have proved to be successful solutions: (1) waste gating air or exhaust gas at full load and speed, (2) using a compounded or independent exhaust gas driven power turbine that can be shut off at part load and speed, and (3) blowing air from the compressor outlet to the turbine inlet through a controlled bypass. The effect of these control interventions on engine performance is shown by examples and analyzed by means of characteristic quantities for the efficiency of the turbocharging system and the engine. The definitions and meanings of these quantities are explained in the first part of the paper.

Book Description
The future market forces and environmental considerations in the passenger car and commercial vehicle sector mean more stringent engine downsizing is far more prevalent. Therefore, novel systems are required to provide boosting solutions including hybrid, electric-motor and exhaust waste energy recovery systems for high efficiency, response, reliability, durability and compactness. The current emission legislations and environmental trends for reducing CO2 and fuel consumption are the major market forces in the land and marine transport industries. The internal combustion engine is the key product and downsizing, efficiency and economy are the driving forces for development for both spark ignition (SI) and compression ignition (CI) engines in both markets. Future market forces and environmental considerations for transportation, specifically in the passenger car, commercial vehicle and the marine sectors mean more stringent engine downsizing. This international conference is the latest in the highly successful and prestigious series held regularly since 1978. These proceedings from the Institution’s highly successful and prestigious series address current and novel aspects of turbocharging systems design, boosting solutions for engine downsizing and improvements in efficiency, and present the latest research and development in this growing and innovative area. Focuses on boosting solutions including hybrid, electric-motor and exhaust waste energy recovery systems Explores the current need for high efficiency, reliability, durability and compactness in recovery systems Examines what new systems developments are underway
Concepts in Turbocharging for Improved Efficiency and Emissions Reduction
Author: Mehrdad ZangenehPublisher: SAE International
ISBN: 0768081491
Category : Technology & Engineering
Languages : en
Pages : 94
Book Description
Legislative requirements to reduce CO2 emissions by 2020 have resulted in significant efforts by car manufacturers to explore various methods of pollution abatement. One of the most effective ways found so far is by shortening the cylinder stroke and downsizing the engine. This new engine then needs to be boosted, or turbocharged, to create the full and original load torque. Turbocharging has been and will continue to be a key component to the new technologies that will make a positive difference in the next-generation engines of years to come. Concepts in Turbocharging for Improved Efficiency and Emissions Reduction explores the many ways that turbocharging will deliver concrete results in meeting the new realities of sustainable, green transportation. This collection of very focused technical papers, selected by Mehrdad Zangeneh, PhD., a professor of thermo-fluids at University College in London, provides an assessment of several novel designs intended to improve fuel consumption and cap emissions, while maintaining torque at all speeds. The book is divided into four sections, each addressing the most cutting-edge technologies on the market today: o Two-Stage Turbocharging o Variable Geometry Compressors o Unconventional Compressor Configurations o Electrically Assisted Turbocharging

ISBN: 0081009739
Category : Technology & Engineering
Languages : en
Pages : 299
Book Description
Tribological Processes in Valvetrain Systems with Lightweight Valves: New Research and Modelling provides readers with the latest methodologies to reduce friction and wear in valvetrain systems—a severe problem for designers and manufacturers. The solution is achieved by identifying the tribological processes and phenomena in the friction nodes of lightweight valves made of titanium alloys and ceramics, both cam and camless driven. The book provides a set of structured information on the current tribological problems in modern internal combustion engines—from an introduction to the valvetrain operation to the processes that produce wear in the components of the valvetrain. A valuable resource for teachers and students of mechanical or automotive engineering, as well as automotive manufacturers, automotive designers, and tuning engineers. Shows the tribological problems occurring in the guide-light valve-seat insert Combines numerical and experimental solutions of wear and friction processes in valvetrain systems Discusses various types of cam and camless drives the valves used in valve trains of internal combustion engines—both SI and CI Examines the materials used, protective layers and geometric parameters of lightweight valves, as well as mating guides and seat inserts
