Abstract
According to the present invention, a power transmission apparatus for an internal combustion engine (2) having a supercharger (1) attached thereto is constructed such that thermal energy included in exhaust gas discharged from a turbine (T) in the supercharger is recovered by a waste heat recovering turbine (3) thereby to drive the waste heat recovering turbine (3), auxiliary units (9), (10) for a cooling system of the internal combustion engine (2) are driven by power generated by the waste heat recovering turbine (3) which has been driven and the power generated by the wasted heat recovering turbine (3) is then transmitted to a crankshaft (12) of the internal combustion engine (2) via a coupling (6) for interrupting power transmission in an operational region where the internal combustion engine is rotated at a low speed or in an operational region where the internal combustion engine is rotated under a low load.
