ABSTRACT:
Disclosed is a type of an exhaust gas energy recovery method for an internal combustion engine of a type which incorporates a turbine generator driven by the exhaust gas energy of the internal combustion engine and in which the driving power of a motor driven by the power generated by the generator is added to the driving power of the internal combustion engine. The method also incorporates a control device for controlling the output torque of the motor in different forms at low and high speed areas within a variable control range of the rotation speed of the internal combustion engine. The motor is operated with constant torque characteristics at the low speed area and with reduced torque characteristics at the high speed area thereby enabling the exhaust gas energy to be efficiently recovered at an engine speed area where the ratio of engine-operating time is high.
