Abstract
A turbo compound engine comprising an engine, a power turbine provided in the exhaust gas passage of the engine, the power turbine being rotatable both in normal and reverse senses, a reversing mechanism including a friction type clutch connecting the power turbine with the crankshaft, with the rotating direction of the power turbine being reversed when the friction type clutch is switched into its engagement mode, and an oil pump and a controller therefor which, in combination, cause the friction type clutch to produce frictional torque large enough to stop the power turbine as the clutch is switched to its engagement mode and further to produce a larger amount of frictional torque within its upper limit when required.
