Title
(EN) METHODS AND APPARATUS FOR AN ACTIVELY COOLED CYLINDER
(FR) PROCÉDÉS ET APPAREIL POUR UN CYLINDRE ACTIVEMENT REFROIDI
Abstract
(EN)
An actively cooled air cylinder for a motorcycle engine comprising a cylinder block. The cylinder block may comprise an upper mounting surface, a lower mounding surface, an internal bore extending between the upper mounting surface and the lower mounting surface, a forward facing surface, a rear facing surface, and first and second side surfaces. Each of the surfaces may comprise a plurality of fins and a plurality of cooling channels located between each of the plurality of fins. The cooling channels may comprise a series of peaks and valleys that configured provide turbulent flow of air over the cylinder block when airflow contacts the cylinder.
(FR)
L'invention concerne un cylindre à air activement refroidi pour un moteur de motocyclette comprenant un bloc-cylindre. Le bloc-cylindre peut comprendre une surface de montage supérieure, une surface de montage inférieure, un alésage interne s'étendant entre la surface de montage supérieure et la surface de montage inférieure, une surface orientée vers l'avant, une surface orientée vers l'arrière, et des première et seconde surfaces latérales. Chacune des surfaces peut comprendre une pluralité d'ailettes et une pluralité de canaux de refroidissement situés entre chacune de la pluralité d'ailettes. Les canaux de refroidissement peuvent comprendre une série de pics et de vallées qui sont configurés de façon à produire un écoulement turbulent d'air sur le bloc-cylindre quand l'écoulement d'air vient en contact avec le cylindre.
