The invention relates to a two-stroke internal combustion engine (diesel) with two or three movable crankshafts interconnected by belts or chains. The movable crankshaft bearings are installed in eccentric holes relative to the circumference of the rotating discs. The rotating discs are firmly connected to each other for each bearing (the eccentric holes must be perfectly coaxial). The activator can rotate all the rotating discs in a perfectly synchronized manner and will modify the distance between the two crankshafts; as a result, it will modify the distance between the opposed pistons and therefore the compression rate will be modified. The engine can have one or more cylinders along the crankshaft axes.
L'invention concerne un moteur à combustion interne (diesel), en deux temps
avec deux
vilebrequins (ou trois vilebrequins) mobiles interconnectés par des courroies
ou chaînes. Les
paliers des vilebrequins mobiles sont installés dans des trous excentriques
par rapport à la
circonférence des disques rotatifs. Les disques rotatifs sont assemblés
solidement entre eux pour
chaque vilebrequin (les trous excentriques doivent être parfaitement
coaxiales).
L'activateur peut faire la rotation de tous les disques rotatifs de manière
parfaitement
synchronisée et va modifier la distance entre les deux vilebrequins, par
conséquence, il va
modifier la distance entre les pistons-opposés et donc le taux de compression
sera modifié. Le
moteur peut avoir un cylindre ou plusieurs cylindres, à la longueur des axes
des vilebrequins.
