Abstract
The utility model relates to a multi-cylinder engine mixed-flow water cooling integral cylinder cover, which is fixed on the engine body and deletes perforation stud structure to ensure the tightness of the combustion chamber. The cooling water flows through a water inlet (7) and an incoming water dividing pipe (2) from the engine body into the cylinder cover cooling water chamber (5) and the water cooling chambers in all cylinders communicate with each other through a transverse mixing water channel (4). So the cooling water partly flows towards the water outlet on the cylinder cover side surface (8) and partly breadthwise flows along the cylinder cover through the transverse mixing water channel to make the cooling water appear a mixed directly-breadthwise flowing situation and have a long flowing path so as to increase the cooling performance of the cylinder cover.
Description
One, technical field
The utility model relates to engine cylinder cap.
Two, technical background
At present, multicylinder engine extensively adopts the split cylinder head, and promptly the complete machine motor has two above cylinder head.Cylinder head bottom surface and body, cylinder liner, head gasket, piston are formed the engine combustion space of high pressure, sealing.In order to guarantee the sealing of firing chamber, fully reduce the motor axial length simultaneously, when split cylinder head and body are fixedly connected, generally adopt junction of the edges of two sheets of paper stud bolt structure.This junction of the edges of two sheets of paper stud bolt is in engine working process, particularly cylindrical implosion is sent out the higher reinforcing stimulus of pressure ratio, therefore junction of the edges of two sheets of paper stud bolt between adjacent cylinder can bear the alternation additional bending moment that is produced by inhomogeneous pressure of explosion and be out of shape, thereby reduces the sealing reliability of split cylinder head.The cooling water of split cylinder head simultaneously, enter the cylinder head bottom surface from the body end face from bottom to top after, only to after single the split Cooling Water Jacket of Cylinder Head, just directly discharge from water outlet, cooling process is short, and cooling effect is undesirable, thus to engine reliable work bring unfavorable.
Three, summary of the invention
The purpose of this utility model provides a kind of multicylinder engine mixed flow water cooling piece cylinder head, based on the split cylinder head, be fixedly connected between cancellation cylinder head and the body with junction of the edges of two sheets of paper stud bolt structure, make multicylinder engine piece cylinder head cooling water chamber at lateral direction penetrating simultaneously, make cooling water be in the crossing current and the mixed flow state of direct current, help to improve the intensity of cooling of cylinder head.
The utility model is to realize like this, above-mentioned multicylinder engine mixed flow water cooling piece cylinder head, by the cylinder lid, the stud bolt hole, the water inlet aqueduct, the water inlet, osculum and cooling water chamber are formed, it is characterized in that the cylinder lid is an integrated type, have horizontal mixed flow water channel to connect between the cooling water chamber corresponding to each cylinder.
Because multicylinder engine adopts piece cylinder head, so cancelled junction of the edges of two sheets of paper stud bolt structure, has fully guaranteed combustion chamber sealing, there is cross channel to connect simultaneously between this piece cylinder head cooling water chamber, improved the cylinder head intensity of cooling.
Four, description of drawings
Fig. 1 is the whole mixed flow water cooling of a multicylinder engine cylinder head schematic representation, and Fig. 2 is that the A of Fig. 1 is to view.
Among the figure, 1 is the stud bolt hole, and 2 are the water inlet aqueduct, and 3 is water outlet, and 4 is horizontal mixed flow water channel, and 5 is cooling water chamber, and 6 is the cylinder lid, and 7 is the water inlet, and 8 is the cylinder head side, and 9 is the cylinder head bottom surface.
Five, preferred forms
Preferred forms of the present utility model is provided by following accompanying drawing.
Referring to Fig. 1,2, a kind of multicylinder engine mixed flow water cooling piece cylinder head, cylinder bore is 135 millimeters array 6 cylinder diesels, six shared piece cylinder heads of cylinder, the stud bolt hole 1, the diameter that run through on the cylinder lid 6 are 38 stud bolts of M16 * 1.5, by spherical washer, cylinder gasket piece cylinder head and body are fixedly connected, the screw-down torque of every stud bolt is 27 kilogram-metres, can fully guarantee the sealing of firing chamber.Cooling water is that water inlet 7 and 6 external diameters from cylinder head bottom surface 9 of 5 millimeters of Φ are 16 millimeters through 6 diameters of body end face, internal diameter is the water inlet aqueduct 2 of 12 millimeters of Φ, enter Cooling Water Jacket of Cylinder Head 5 simultaneously, cooling water chamber 5 between the adjacent cylinder, there is horizontal mixed flow water channel 4 to connect, after the two-way cooling water enters Cooling Water Jacket of Cylinder Head 5 like this, the cylinder head water outlet 3 of part direct current to the cylinder head side 8, another part is through horizontal mixed flow water channel 4, along cylinder head 6 lateral flow, like this, cooling water forms the mixed flow state of direct current and crossing current in cooling water chamber 5, enter outfall sewer then.Laterally the height of mixed flow water channel 4 is 98 millimeters, and width is 57 millimeters, and when this machine maximum combustion pressure of explosion PZ was 14MPa, cylinder head can fully be cooled off, thereby guarantees that engine operation is safe and reliable.Above-mentioned multicylinder engine mixed flow water cooling piece cylinder head, cylinder number also can be 4,8,10,12 or 16, cylinder is arranged and can be the v type, the multicylinder engine cylinder bore can for 85 millimeters or more than.
