Title (EN) PROPULSION UNIT FOR MOTOR VEHICULE USING A THERMAL ENGINE DOWN TO THE LOWEST WORKING SPEED
(FR) GROUPE PROPULSEUR POUR VEHICULE AUTOMOBILE UTILISANT UN MOTEUR THERMIQUE JUSQU"AUX PLUS BAS REGIMES
Abstract: front page image
(EN)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.
(FR)Le groupe propulseur comporte un moteur thermique avec son volant d"inertie habituel, une machine electrique reversible (2), un accumulateur electrique, un variateur de vitesse (18-20) reliant la machine electrique (2) au moteur thermique et un circuit electrique de commande, l"ensemble etant agence pour assurer le fonctionnement dudit moteur thermique a des regimes tres inferieurs a ceux auxquels son volant d"inertie lui permettrait normalement de fonctionner en regularisant son couple moteur par echanges instantanes alternativement positifs et negatifs d"energie mecanique entre le moteur thermique et la machine electrique et d"energie electrique entre la machine electrique et l"accumulateur.
