Description

выход 18 в сборный канал 13 в наиболее высоком месте.exit 18 to the collection channel 13 in the highest place.

Полость 17 охватывает отверстие 10 и примыкает к полости 16 р дом со стенкой 12.The cavity 17 covers the hole 10 and adjoins the cavity 16 adjacent to the wall 12.

В корпусе головки между соседними цилиндрами 8 выполнены отверсти  19 дл  прохода элементов креплени  головки блока , каналы 20 дл  подвода смазки (на каждый цилиндр) и проемы 21 (фиг. 4).In the head housing between adjacent cylinders 8, holes 19 are made for the passage of the block head fastening elements, channels 20 for supplying lubricant (for each cylinder) and openings 21 (Fig. 4).

В процессе работы двигател  охлаждающа  вода через каналы 14, 15 попадает в полости 16, 17 и через вход 18 попадает в сборный канал 13.In the process of the engine operation, cooling water through the channels 14, 15 enters the cavities 16, 17 and through the inlet 18 enters the collection channel 13.

Таким образом относительно каждого цилиндра 8 устанавливаетс  поперечный поток охлаждени , который обуславливает равномерное и интенсивное охлаждение областей головки блока, которые соответствуют своему цилиндру 8. Подъем стенки 12 от торца 5 к торцу 4 головки совместно с протекающей водой обеспечивает удаление возникающих воздушных пузырьков по вл ющихс  вследствие кавитации, кипени  и других  влений в сборный канал 13.Thus, a transverse cooling flow is established relative to each cylinder 8, which causes uniform and intensive cooling of the areas of the head of the block, which correspond to its cylinder 8. The rise of the wall 12 from the end 5 to the end 4 of the head together with the flowing water ensures the removal of air bubbles arising due to cavitation, boiling and other phenomena in the collection channel 13.

Внутри канала 13 поток охлаждающей воды циркулирует в направлении L, а через окно 2 на конце канала 13 также подаетс  охлаждающа  вода..Inside the channel 13, a flow of cooling water circulates in the L direction, and cooling water is also supplied through a window 2 at the end of the channel 13.

Внутри сборного канала 13 сопротивление потоку циркулирующей воды мало, т.к. в канале (благодар  его расположению в области S) отсутствуют какие-либо изгибы, например обусловленные наличием газообменных каналов.Inside the collection channel 13, the flow resistance of the circulating water is small, because in the channel (due to its location in region S) there are no bends, for example, due to the presence of gas exchange channels.

Такое малое сопротивление обуславливает быстрое прохождение полостей 16 и 1.7 и тем самым быстрый нагрев воды при запуске двигател , а также эффективное охлаждение при длительной работе двигател .Such a low resistance leads to the rapid passage of the cavities 16 and 1.7 and thereby the rapid heating of the water when starting the engine, as well as effective cooling during prolonged operation of the engine.
