This book covers the fluid mechanics, thermodynamics, and technology for achieving variable valve actuation and power boost. Contents include: dynamic model of a springless electrohydraulic valvetrain; a novel, fully flexible, electro-mechanical engine valve actuation system; mechanical fully implemented with a secondary valve on a four cylinder SI engine; development of gear parts for VVT unit; a low-friction variable-valve actuation device part II: analysis and simulation; tecnologies for a turbocharged and intercooled heavy-duty diesel engine; development of SJ (swirl jet) turbocharger for diesel engine vehicles; variable valve actuation and diesel engine retarding performance; particle image velocitymetry characterization of a turbocharger turbine inlet flow; and the design and operation of a turbocharger test facility designed for transient simulation.
