Abstract

The invention relates to a cylinder body water jacket of an engine. The cylinder body water jacket comprises a main cylinder body of the engine; the main cylinder body of the engine is provided with cylindrical air cylinder holes, and a cylinder body water jacket with a roughly ring-shaped circumferential contour is arranged along the circumferential wall of each air cylinder hole; and a nose bridge area of the main cylinder body of the engine is provided with a cooling water tank with a strip cross section, both ends of the cooling water tank are communicated with the ring-shaped cylinder body water jacket. In the cylinder body water jacket of the engine, the water cooling tank is processed on the nose bridge area between the two air cylinder holes of the cylinder body of the engine, and the cooling water is made to pass through the nose bridge area where the temperature is the highest on the cylinder body when the engine operates, so that the cooling efficiency is high. Under a condition of meeting the requirement of the compact arrangement of the cylinder body of the engine, the cooling of the nose bridge area is realized, the processing is convenient, the processing efficiency is higher, and the processing cost is lower.

Description

A kind of cylinder body water jacket of engine
Technical field
The present invention relates to technical field of engines, especially a kind of cylinder body water jacket of engine.
Background technique
Present most of cylinder body water jacket of engine is offered oblique water hole intersection or V-type in the cylinder body nasal bridge region by the mode of processing in order to cool off the nasal bridge region temperature in the middle of two cylinder holes, makes cooling water realize cooling to this zone by oblique water hole.In addition, present engine cylinder body structure is more and more compacter, makes the space of cylinder body nasal bridge region more and more littler, tiltedly the layout in water hole is also more and more difficult, tiltedly the diameter in water hole generally all more than 3mm, the oblique too little words processing difficulties in water hole, the cutter of boring is disconnected easily, and work efficiency is lower.Simultaneously, the reinforcing degree of motor is more and more higher, and the operating temperature of cylinder body nasal bridge region is also more and more higher, and the cooling in this zone is again necessary.
Summary of the invention
The object of the present invention is to provide a kind ofly can fully cool off, be convenient to process the nasal bridge region of engine cylinder-body, cylinder body water jacket of engine that cooling effectiveness is high.
For achieving the above object, the present invention has adopted following technological scheme: a kind of cylinder body water jacket of engine, comprise the engine cylinder-body body, offer cylindrical cylinder-bore on the engine cylinder-body body, arrange roughly in the form of a ring cylinder body water jacket of peripheral profile along the periphery wall of cylinder-bore, the bridge of the nose district of described engine cylinder-body body offers the bosh that cross section is strip, and the two ends of bosh connect with the cylinder body water jacket of annular.
As shown from the above technical solution, the present invention offers a bosh by the nasal bridge region of mode between engine cylinder-body two cylinder-bore of processing, make cooling water when engine running from the cylinder body the highest nasal bridge region of temperature flow through, cooling effectiveness is the highest.Satisfying under the compact situation of engine cylinder-body layout, offer the bosh that is strip in bridge of the nose district, be convenient to processing, work efficiency is higher, and processing cost is lower.

Fig. 4 is the structural representation of cylinder body water jacket cavity body;
Fig. 5 is the structural representation of bridge of the nose district and cylinder body water jacket cavity body.
Embodiment
A kind of cylinder body water jacket of engine, comprise engine cylinder-body body 10, offer cylindrical cylinder-bore 11 on the engine cylinder-body body 10, arrange roughly in the form of a ring cylinder body water jacket 12 of peripheral profile along the periphery wall of cylinder-bore 11, the cylinder body water jacket 12 of described annular is the circuit cooling water passage of arranging around the periphery wall of cylinder-bore 11 integral body, the water inlet 15 of cylinder body water jacket 12 is arranged in the tangent direction of water jacket body, this water inlet 15 is connected with the water outlet of water pump, as Fig. 1, shown in 4, the cooling water in the cylinder body water jacket 12 finally flows out from cylinder head water cover water outlet after heat exchange.
In conjunction with Fig. 1,2,3,4,5, offer the bosh 14 that cross section is strip in the bridge of the nose district 13 of described engine cylinder-body body 10, the two ends of bosh 14 connect with the cylinder body water jacket 12 of annular.Described bridge of the nose district 13 is meant the zone between the adjacent cylinder-bore 11 of two-phase on the engine cylinder-body body 10, the zone that temperature is the highest on the engine cylinder-body during engine running is exactly the top in two bridge of the nose districts 13 between the adjacent cylinder hole 11, the highest zone of temperature on engine cylinder-body left by bosh 4, make cooling water can flow through on the engine cylinder-body the highest zone of temperature when work, realization is to the cooling in this zone, and cooling effectiveness is the highest.The counter clockwise direction shown in the arrow is the water (flow) direction of cooling water in the cylinder body water jacket 12 among Fig. 4,5.
In conjunction with Fig. 1,2,3,4,5, the length direction of described bosh 14 cross sections is vertical with the length direction of engine cylinder-body body 10, the two ends of bosh 14 have horn-like port 16 to be connected with cylinder body water jacket 12, bosh 14 is positioned at the position, aperture of cylinder-bore 11, and be opened in the medium position in bridge of the nose district 13, the groove width of bosh 14 is 0.8 to 2 millimeter.The width of bosh 14 can be selected between 0.8 to 2 millimeter according to cooling requirement and layout requirement, and this structure can avoid damaging machining tool, and work efficiency is higher.
In sum, the present invention offers a bosh by the bridge of the nose district 13 of mode between the adjacent cylinder-bore 11 of engine cylinder-body two of processing, make cooling water when engine running from the cylinder body the highest bridge of the nose district 13 of temperature flow through, realize the abundant cooling in bridge of the nose district 13 and the maximization of cooling effectiveness.Satisfying under the compact situation of engine cylinder-body layout, offering the bosh 14 of strip in bridge of the nose district 13, be convenient to processing, work efficiency is higher, and processing cost is lower.
