Abstract

Изобретение позвол ет повысить надежность в работе крышки цилиндра за счет уменьшени  радиального перепада температур по днищу. Охладитель поступает в нижнюю часть 9 полости 1 охлаждени  головки, омывает засыпку из стальных шариков 14, свободно размещенную на огневом днище 3 и обеспечивающую более эффективный и равномерный отвод теплоты от огневого днища, и по каналам в межклапанных перемычках 11, омыва  поверхность стакана форсунки 6, направл етс  в верхнюю часть 8 полости охлаждени  1 головки цилиндра. Такое выполнение позвол ет обеспечить выравнивание температурного пол  днища путем организации процесса парообразовани . 3 ил.The invention makes it possible to increase the reliability of the cylinder head by reducing the radial temperature difference across the bottom. The cooler enters the lower part 9 of the head cooling cavity 1, washes a filling of steel balls 14, freely placed on the firing bottom 3 and providing a more efficient and uniform heat removal from the firing bottom, and through channels in the inter-valve jumpers 11, washing the surface of the nozzle 6, directed to the upper part 8 of the cooling cavity 1 of the cylinder head. This embodiment allows for the alignment of the bottom temperature field by organizing the process of vaporization. 3 il.
