The propulsion unit comprises a thermal engine with its conventional inertia wheel, a reversible electric machine (2), an electric accumulator, a speed variator (18-20) connecting the electric machine to the thermo engine and a control electric circuit, the whole being arranged to provide for the running of said thermo engine at running speeds much lower than those at which its inertia wheel would otherwise allow it to operate by regulating its engine torque by instantaneous exchanges alternatively positive and negative of mechanical energy between the thermal engine and the electric machine and of electric energy between the electric machine and the accumulator. |
