Title (EN) VARIABLE ANGLE CAM-DRIVE ENGINE AND A POWER CONVERSION MECHANISM FOR USE THEREIN
(FR) MOTEUR D'ENTRAINEMENT A CAME A ANGLE VARIABLE ET UN MECANISME DE CONVERSION D'ENERGIE DESTINE A Y ETRE UTILISE
Abstract:
(EN) A variable angle cam-drive engine (100) in which the torque output generated at a given engine speed (as represented by, for example, piston reciprocation frequency) can be varied by changing the operating angle of cam mechanisms (154) in a power conversion mechanism (150) of the engine. A power conversion mechanism (150), having a plurality of cam mechanisms (154) and a cam-angle mechanism (185) , for use in a variable angle cam-drive engine (100) that can vary the torque output generated at a given engine speed by changing the cam-angle of the plurality of cam mechanisms (154) using the cam-angle mechanism (185).
(FR) La présente invention a trait à un moteur d'entraînement à came à angle variable (100) dans lequel la sortie du couple généré à un régime du moteur donné (tel que représenté, par exemple, par la fréquence de mouvement alternatif de pistons) peut être varié par la modification de l'angle de fonctionnement des mécanismes de came (154) dans un mécanisme de conversion d'énergie (150) du moteur. L'invention a également trait à un mécanisme de conversion (150) comportant une pluralité de mécanismes à came (154) et un mécanisme d'angle de came (185), destinés à être utilisés dans un moteur d'entraînement à came (100) qui peut faire varier la sortie de couple généré à un régime du moteur donné par la modification de l'angle de came d'une pluralité de mécanismes de came (154) à l'aide du mécanisme d'angle de came (185).
