Patent

CA 2138337

An outboard engine structure is provided including an engine mounted in an upper portion of an engine body case, wherein an exhaust gas from the engine is passed through an exhaust passage located vertically within the engine body case, into a lower portion of the case and discharged into water. A catalytic converter is positioned adjacent an oil pan for said engine. The oil pan is mounted in a suspended manner in an upper area within the engine body case and incorporated in the middle of the exhaust passage. The catalytic converter is fixed to and supported on the oil pan. Thus, it is easy to place the catalytic converter in the engine body case and moreover, the temperature of a catalyst is maintained at a suitable level by the transfer of heat from the oil pan, thereby providing efficient catalytic action.

La présente invention fait état d'un moteur hors-bord installé dans la partie supérieure d'un carter. Les gaz d'échappement du moteur pénètrent dans un passage vertical, situé dans le carter, où ils sont acheminés dans la partie inférieure du carter avant d'être évacués dans l'eau. Le carter d'huile est suspendu dans une zone supérieure à l'intérieur du carter et installé au milieu du passage à gaz d'échappement. Un convertisseur catalytique, positionné près du carter d'huile, est fixé et repose sur ce dernier. Le convertisseur catalytique s'installe donc facilement dans le carter et, en outre, il se maintient à la bonne température, grâce au transfert de la chaleur provenant du carter d'huile. Il en résulte, par conséquent, une action catalytique efficace.
