Abstract
An internal combustion engine has a first work extraction station for extracting work from combustion and expansion of working gases. An emission treatment station treats the working gases after leaving the first extraction work station for reducing emissions. A second work extraction station receives the working gases from the emission treatment station for a second extraction of work from the working gases.
