1. An internal combustion engine comprising:

  • a main transmission means;

    at least one accessory means in the form of a motor generator means adapted to function as one of a motor and a generator;

    an accessory drive transmission means for driving said at least one accessory means;

    a load torque controller means, including detection means for detecting a rotational speed variation at each crank angle of the internal combustion engine, for outputting a generator motor function change signal for causing said motor generator means to function as one of said motor and said generator, said rotational speed variation being a differential between an average torque generated by the internal combustion engine over an engine cycle of said internal combustion engine and an instantaneous torque generated by said internal combustion engine at said each crank angle; and

    control means, responsive to said generator motor function change signal and said rotational speed variation detected by said detection means, for controlling a torque to be one of generated and absorbed by said motor generator means to decrease the rotational speed variation of the internal combustion engine at each crank angle.
