When decrepitate is sent out, piston combustion bowl is in top dead center position, therefore cylinder head temperature is highest, it is necessary in cylinder head week
Cooling jacket system is designed on side, is taken away the heat of cylinder head using cooling water, is reduced its temperature.
For the less cylinder block of cylinder centre line spacing, the cooling jacket design commonly used between two cylinders is：Two adjacent cylinder it
Between, two intersection water channels are processed from the top of cylinder block, when cooling water flows through the intersection water channel between two cylinders, cylinder are served cold
But effect.
The intersection water channel of existing design scheme does not have technique taper hole at the top of cylinder block, is primarily present following shortcoming：
Difficulty of processing when the 1st, causing to intersect water channel is larger, and the damage to drill bit is larger, easy breaking of rod head during feed；2nd, it is easy during feed
Drift about, the machining accuracy for intersecting water channel is have impact on, so that the cooling effect between the cylinder of block jacket two is influenceed, to internal combustion
The reliability of machine is unfavorable；3rd, enter slower during knife, processing efficiency is low；4th, because processing efficiency is low, and then it result in processing cost
Increase.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.
