Title
(EN) HYBRID OPPOSED-PISTON INTERNAL COMBUSTION ENGINE
(FR) MOTEUR À COMBUSTION INTERNE HYBRIDE, À PISTONS OPPOSÉS
Abstract
(EN)
A hybrid opposed piston engine is described that can include a cylindrical chamber and first and second pistons slidably disposed in the cylindrical chamber, surfaces of the first and second pistons and walls of the cylindrical chamber defining an internal combustion volume. The hybrid opposed piston engine can also include at least one port in the cylindrical chamber to allow air and fuel into and exhaust gas out of the internal combustion volume. In some embodiments, the hybrid opposed piston engine includes a drive shaft including a first mechanical linkage between the first piston and a crankshaft that is configured to move the first piston within the cylindrical chamber. In some embodiments, the hybrid opposed piston engine includes an electrical component adjacent to the second piston, the electrical component configured to move the second piston within the cylindrical chamber.

L'invention concerne un moteur hybride à pistons opposés qui peut comprendre une chambre cylindrique et des premier et second pistons disposés coulissants dans la chambre cylindrique, les surfaces des premier et second pistons et les parois de la chambre cylindrique délimitant un volume de combustion interne. Le moteur hybride à pistons opposés peut comprendre également au moins un orifice dans la chambre cylindrique afin de permettre l'entrée d'air et de combustible dans le volume de combustion interne et la sortie des gaz d'échappement dudit volume. Selon certains modes de réalisation, le moteur hybride à pistons opposés comprend un arbre d'entraînement comportant une première liaison mécanique entre le premier piston et un vilebrequin conçu pour déplacer le premier piston à l'intérieur de la chambre cylindrique. Selon certains modes de réalisation, le moteur hybride à pistons opposés comprend un composant électrique adjacent au second piston, le composant électrique étant conçu pour déplacer le second piston à l'intérieur de la chambre cylindrique.
