Patent

CA 2580587

The invention involves an engine that the cylinder block contains a coupled piston formed by a main piston, an external piston. The external piston is sleeved outside of the main piston and uses the rods on the two sides to connect to the heart-shape groove on the two sides of the crankshaft inside the crankcase at the bottom of the cylinder block. It moves with the main piston in an upward stroke and in a downward stroke. It forms a direct fuel injection device in the cylinder without carburetor. It does not need to add lubricants in the fuels. Besides, the engine has increased compression ratio. The engine provides enhanced economical benefits and meets today's environmental requirements. It achieves the goals of low pollution, high horse power, small volume, simple structure and durability. It is technical breakthrough in the development of internal combustion engine.

L'invention a trait à un moteur dont le bloc-cylindres contient un piston couplé composé d'un piston principal et d'un piston externe. Ce dernier, chemisé à l'extérieur du piston principal, se sert des tiges situées des deux côtés pour se connecter à une rainure en forme de cour située de part et d'autre du vilebrequin à l'intérieur du carter, sous le bloc-cylindres. Le piston externe se déplace en même temps que le piston principal dans sa course vers le haut et vers le bas. Il sert de dispositif d'injection directe de combustible dans le cylindre, sans carburateur, et il n'est nul besoin d'ajouter de lubrifiants aux combustibles. En outre, le taux de compression du moteur est accru. Le moteur offre des avantages économiques bonifiés en plus de répondre aux exigences environnementales actuelles. Il est peu polluant, combine une puissance élevée à un volume restreint, sa structure est simple et il est durable. Il s'agit d'une percée technique en matière de moteur à combustion interne.
