(54)ГОЛОВКА ЦИЛИНДРА ДВИГАТЕЛЯ ВНУТРЕННЕГО СГОРАНИЯ(54) HEAD OF INTERNAL COMBUSTION MOTOR CYLINDER
(57)Изобретение позвол ет повысить экономичность двигател путем снижени тепловых потерь и снижени тепло- напр женности межклапанной перемычки.(57) The invention improves engine efficiency by reducing heat loss and decreasing the thermal stress of the inter-valve jumper.
Днище головки цилиндра выполнено составным по меньшей мере из двух деталей (Д). Внутренн Д 2 размещена в цилиндрическом отверстии, выполненном во внешней Д 3. Полость охлаждени образована углублени ми 3 и 6, выполненными в сопр женных поверхност х 4 Д 2 и 3 либо только на Д 2. Верхн часть головки выполнена из материала с низким козффициентом теплопроводности . В результате снижаютс тепловые потери в окружающую среду через стенки выпускных каналов, повышаетс надежность двигател за счет снижени теплонапр женности межкла- панной перемычки в днище головки. 1 3.п. ф-лы, 2 ил.The bottom of the cylinder head is made of a composite of at least two parts (D). The inner D 2 is placed in a cylindrical hole made in the outer D 3. The cooling cavity is formed by recesses 3 and 6, made in the mating surfaces 4 D 2 and 3 or only on D 2. The upper part of the head is made of a material with a low thermal conductivity coefficient. . As a result, the heat losses to the environment through the walls of the exhaust channels are reduced, the engine reliability is increased by reducing the thermal stress of the inter-valve valve in the bottom of the head. 1 3.p. f-ly, 2 ill.
