INTERNAL COMBUSTION ENGINE WITH IMPROVED FORCED AIR-COOLING

INTERNAL COMBUSTION ENGINE WITH IMPROVED FORCED AIR-COOLING

Disclosed is an internal combustion engine (110) having a forced air-cooling system comprising a fan (25) located outward from a centre line (Cl) of said engine (110) for directing a cooling air flow through an air passage (116) toward engine components to be cooled; a ring gear (24) and ring gear d...

Zusammenfassung:Disclosed is an internal combustion engine (110) having a forced air-cooling system comprising a fan (25) located outward from a centre line (Cl) of said engine (110) for directing a cooling air flow through an air passage (116) toward engine components to be cooled; a ring gear (24) and ring gear drive (27) co-operable with the ring gear (24) during starting of the engine (110); and a magneto rotor (23) rotated by a crankshaft (22) of the engine (110) wherein said ring gear (24) and said fan (25) are mounted to said magneto rotor (23), the ring gear (24) being mounted inward of and spaced from both the fan (25) and the air passage (116) and towards the centre line (Cl) of the engine (110). L'invention concerne un moteur à combustion interne (110) possédant un système de refroidissement à ai forcé comprenant un ventilateur (25) placé en dehors d'un axe du moteur (110) de façon à diriger un écoulement d'air de refroidissement dans un passage correspondant (116) vers les composants du moteur à refroidir; et une couronne (24) et un pignon de commande (27) de la couronne coopèrent lors du démarrage du moteur (110) ; le vilebrequin (22) du moteur (110) met en rotation un rotor de magnéto (23) sur lequel sont montés la couronne (24) et le ventilateur (25), la couronne (24) étant montée à l'intérieur et espacée du ventilateur (25) et du passage d'air (116) et orientée vers l'axe du moteur (110).
