The holistic view of powertrain development that includes engine, transmission and driveline is now well accepted. Current trends indicate an increasing range of engines and transmissions in the future with, consequently, a greater diversity of combinations. Coupled with the increasing introduction of hybrid vehicles, the scope for research, novel developments and new products is clear. This volume presents a collection of papers from the Institution of Mechanical Engineers Conference Integrated Powertrain and Driveline Systems 2006 (IPDS 2006) organised by the IMechE Automobile Division. Main themes include transmissions; concept to market evolution; powertrain integration; and engine integration. Novel concepts relating, for example, to continuously variable transmissions (CVTs) and hybridization are discussed, as well as approaches to modelling and simulation.
The Institution of Mechanical Engineers (IMechE) is one of the leading professional engineering institutions in the world.
