This handbook deals with the vast subject of thermal management of engines and vehicles by applying the state of the art research to diesel and natural gas engines. The contributions from global experts focus on management, generation, and retention of heat in after-treatment and exhaust systems for light-off of NOx, PM, and PN catalysts during cold start and city cycles as well as operation at ultralow temperatures. This book will be of great interest to those in academia and industry involved in the design and development of advanced diesel and CNG engines satisfying the current and future emission standards.

A systematic control of mixture formation with modern high-pressure injection systems enables us to achieve considerable improvements of the combustion pr- ess in terms of reduced fuel consumption and engine-out raw emissions. However, because of the growing number of free parameters due to more flexible injection systems, variable valve trains, the application of different combustion concepts within different regions of the engine map, etc., the prediction of spray and m- ture formation becomes increasingly complex. For this reason, the optimization of the in-cylinder processes using 3D computational fluid dynamics (CFD) becomes increasingly important. In these CFD codes, the detailed modeling of spray and mixture formation is a prerequisite for the correct calculation of the subsequent processes like ignition, combustion and formation of emissions. Although such simulation tools can be viewed as standard tools today, the predictive quality of the sub-models is c- stantly enhanced by a more accurate and detailed modeling of the relevant pr- esses, and by the inclusion of new important mechanisms and effects that come along with the development of new injection systems and have not been cons- ered so far. In this book the most widely used mathematical models for the simulation of spray and mixture formation in 3D CFD calculations are described and discussed. In order to give the reader an introduction into the complex processes, the book starts with a description of the fundamental mechanisms and categories of fuel - jection, spray break-up, and mixture formation in internal combustion engines.

The book describes the collection of the Museum Engines and Mechanisms of the University of Palermo, Italy, one of the most important and heterogeneous collections of engines and mechanisms in Europe, the first one in Italy to be awarded as Mechanical Engineering Heritage Collection by the American Society of Mechanical Engineers. Thanks to its numerous items, this book showcases the evolution of fluid machinery and applied mechanics, from steam engines up to turbojet engines, as well as hybrid system, giving several technical and historical information about its most important engines, which are described in detail through pictures and original drawings. The Museum preserves and makes freely available this almost unique collection of more than 300 engines, didactic models, and technical equipment, including various unique exemplars, continuously enhanced thanks to donations and through restoration activities carried out in a dedicated laboratory of the Museum. As a result of a great deal of philological research carried out on the documents collected in the Museum’s archive, as well as in other institutional and corporate historical archives, this book serves as the reference tool of the collection and, more generally, of the Museum itself. Despite the technical subject and the academic environment in which it was created, the catalogue is realized to be read even by non-experts, offering different levels of detail, the first of which is the historical, economic and, in certain cases, even sporting context related to an engine, such as the vehicle for which it was designed and used.

This book traces the diffusion trajectory of the second and third generation of British steam engines, the Watt and high-pressure models, covering the period 1774 to 1870. It begins by subjecting to econometric analysis the latest version of Dr. Kanefsky's database on 18th century steam engines coming up with an upward revision of the total amount of horsepower installed by 1800. Subsequent chapters delve into the determinants of the diffusion process through the third quarter of the 19th century relating to engines used both in mining and industry as well as transportation (railways, steam cars).

Marine engines are efficient machines, but stricter legislation about emissions makes continuous research necessary in order to reduce their consumption and improve their efficiency. This Special Issue, "Marine Engines Performance and Emissions II", is a continuation of "Marine Engines Performance and Emissions". It contains a set of peer-reviewed works about marine engine performance and emissions.
