Abstract

"MOTOR DE COMBUSTãO INTERNA REFRIGERADO A AR". A presente invenção refere-se a um motor de combustão interna para aperfeiçoar o efeito de refrigeração a ar em uma passagem de refrigeração a ar e proporcionar uma vela de ignição em uma posição tal que permite montagem e desmontagem facilitadas, ao mesmo tempo em que possibilita a sua refrigeração a ar efetiva. O motor de combustão interna refrigerado a ar (1) que inclui um mecanismo de comando de válvulas proporcionado acima de uma câmara de combustão (6), e uma passagem de ar de refrigeração que se estende na direção longitudinal (32) entre a câmara de combustão (6) e o mecanismo de comando de válvulas ao longo de um orifício de escapamento (7) e um orifício de admissão (9), proporciona-se uma passagem de ar de refrigeração que se estende lateralmente em comunicação com a passagem de ar de refrigeração que se estende na direção longitudinal (32) entre o orifício de escapamento (7) e o orifício de admissão (9), uma vela de ignição (27) proporcionada na passagem de ar de refrigeração que se estende lateralmente (35), e uma aleta de refrigeração encurvada a partir da passagem de ar de refrigeração que se estende na direção longitudinal (32) no sentido da passagem de refrigeração que se estende lateralmente (35). Além disso, uma linha de centro do orifício de escapamento (7) fica inclinada com relação à direção longitudinal de um motor de combustão interna de maneira a alargar a abertura frontal da passagem de ar de refrigeração que se estende na direção longitudinal (32)."AIR-COOLED INTERNAL FUEL ENGINE". The present invention relates to an internal combustion engine for enhancing the air-cooling effect in an air-cooled passageway and providing a spark plug in such a position as to permit easy assembly and disassembly, while enabling effective air cooling. The air-cooled internal combustion engine (1) including a valve control mechanism provided above a combustion chamber (6), and a longitudinally extending cooling air passage (32) between the combustion chamber combustion (6) and the valve drive mechanism along an exhaust port (7) and an intake port (9), a laterally extending cooling air passageway is provided in communication with the air passageway in the longitudinal direction (32) between the exhaust port (7) and the intake port (9), a spark plug (27) provided in the laterally extending cooling air passage (35), and a bent cooling vane from the longitudinally extending cooling air passage (32) towards the laterally extending cooling passage (35). In addition, a centerline of the exhaust port (7) is inclined with respect to the longitudinal direction of an internal combustion engine to widen the front opening of the cooling air passageway extending in the longitudinal direction (32).
