Brief description
Below the labelling of the content expressed by this specification each width accompanying drawing and in figure is briefly described:
Fig. 1 is the first embodiment cross-sectional schematic of water-jacket typ exhaust manifold of the present invention.
Fig. 2 is water-jacket typ exhaust manifold second embodiment cross-sectional schematic of the present invention.
Fig. 3 is the third embodiment cross-sectional schematic of water-jacket typ exhaust manifold of the present invention.
In figure: 1. exhaust passage, 2. jacket passage, 3. engine cooling water manifold passage.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is made further details of
Explanation.
As shown in Figure 1 to Figure 3, this water-jacket typ exhaust manifold, including exhaust passage 1, jacket passage 2, engine cooling water
It is one overall that manifold passage 3, exhaust passage 1 and jacket passage 2 and engine cooling water manifold passage 3 are integrated casting
Structure, is integrated into a part, reduces engine component quantity, simple and compact for structure, reduces total quality.
Exhaust passage 1 is arranged in the cavity of jacket passage 2, and engine cool supply mains 3 passage is arranged on exhaust passage 1
Outside, be arranged side by side inside and outside exhaust passage and jacket passage and engine cooling water manifold passage, compact conformation.By water
The water of set passage is lowered the temperature to the exhaust manifold of electromotor, extends the service life of exhaust manifold.
The tube wall of engine cooling water manifold passage 3 is not coincided with the tube wall of exhaust passage 1, it is to avoid heat transfer mistake
Hurry up.The tube wall of jacket passage 2 has common sparing with the tube wall of engine cooling water manifold passage 3, and electromotor as shown in Figure 2 is cold
But partly enclosing of 0～360 ° of angle of supply mains's passage is covered；Or engine cooling water manifold passage is located in the cavity of jacket passage,
Entirely enclosing of 0～360 ° of angle of engine cool supply mains as shown in Figure 3 covers arrangement.Both structures are all simple, reduce entirety
Dimensions, compact attractive in appearance, it is easily installed arrangement.
Cooling water in engine cooling water manifold passage 3 is that reverse cooling is lowered the temperature, in the advanced cylinder head of cooling water,
Enter back into cooling in cylinder body；Or the cooling water in engine cooling water manifold passage is that positive cooling is lowered the temperature, cooling
In water elder generation cylinder block, enter back into cooling in cylinder head.
Exhaust passage in the cavity of jacket passage 2 is a group being arranged side by side, and can be two or four being arranged side by side
Individual, compact conformation.
Electromotor, using above-mentioned water-jacket typ exhaust manifold.By the exhaust passage of water-jacket typ exhaust manifold and electromotor
Air vent is connected.Compact conformation, reduces engine component quantity.
By integrated engine cooling water manifold passage, realize engine tail gas waste-heat and reclaim, fast lifting interior circulation
