Summary

A significant driver for the development of future commercial vehicles is the introduction of fuel consumption related legislation around the world. The application of a waste heat recovery system, via the Rankine Cycle, is seen as a possible technology, amongst many, to help achieve this legislation. Following on from the results of theoretical studies, which were presented at the Vienna Motorsymposium in 2009, a representative heavy duty commercial vehicle engine running on the test bed at Euro VI emissions levels has been fitted with a complete prototype Rankine Cycle system. This combination has been tested successfully under steady state and transient conditions in order to establish the feasibility and potential of the technology.
