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.

Next-Generation Batteries with Sulfur Cathodes provides a comprehensive review of a modern class of batteries with sulfur cathodes, particularly lithium-sulfur cathodes. The book covers recent trends, advantages and disadvantages in Li-S, Na-S, Al-S and Mg-S batteries and why these batteries are very promising for applications in hybrid and electric vehicles. Battery materials and modelling are also dealt with, as is their design, the physical phenomena existing in batteries, and a comparison of batteries between commonly used lithium-ion batteries and the new class of batteries with sulfur cathodes that are useful for devices like vehicles, wind power aggregates, computers and measurement units.
