Turbocompound engine 

                                                   Abstract

A turbocompound engine having a stratified charge or diesel cycle rotary internal
combustion engine, with a first output shaft and a turbine engine with a second
output shaft. The first and second output shafts are coupled together so that the
shafts rotate in synchronism with each other and provide a rotary output from the
turbocompound engine. A valve variably directs air inducted into the engine between
the turbine engine and internal combustion engine in dependence upon
engine operating conditions.
