Abstract

Circuit comprenant des trous de refroidissement du fond de la culasse et des canaux de refroidissement de sièges de soupape. Les trous de refroidissement du fond de la culasse et les canaux de refroidissement de sièges de soupape sont disposés séparément et sont refroidis indépendamment. Les trous de refroidissement du fond font partie d'un réseau autonome dans lequel circule un premier fluide et les canaux de refroidissement de sièges de soupapes font partie d'un autre réseau qui est séparé et indépendant du premier et dans lequel circule un second fluide. La température du second fluide est d'environ 60 degrés C, tandis que celle du premier est supérieure à 110 degrés C. Application aux grands moteurs Diesel.Circuit comprising cylinder head bottom cooling holes and valve seat cooling channels. The cylinder head bottom cooling holes and valve seat cooling channels are arranged separately and are cooled independently. The bottom cooling holes are part of an autonomous network in which a first fluid circulates and the valve seat cooling channels are part of another network which is separate and independent from the first and in which a second fluid circulates. The temperature of the second fluid is approximately 60 degrees C, while that of the first is greater than 110 degrees C. Application to large diesel engines.
