Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described:
Fig. 1 is the first embodiment's cross-sectional schematic of the utility model water jacket type gas exhaust manifold.
Fig. 2 is the utility model water jacket type gas exhaust manifold the second embodiment cross-sectional schematic.
Fig. 3 is the third embodiment's cross-sectional schematic of the utility model water jacket type gas exhaust manifold.
In figure: 1. exhaust passage, 2. jacket passage, 3. engine cooling water manifold passage.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, this water jacket type gas exhaust manifold, comprise exhaust passage 1, jacket passage 2, engine cooling water manifold passage 3, exhaust passage 1 and jacket passage 2 and engine cooling water manifold passage 3 are integrated an overall structure of casting, be integrated into parts, reduce engine component quantity, simple and compact for structure, reduce total quality.
Exhaust passage 1 is arranged in the cavity of jacket passage 2, and engine cooling water manifold passage 3 is arranged on the outside of exhaust passage 1, is arranged side by side, compact structure inside and outside exhaust passage and jacket passage and engine cooling water manifold passage.By the water of jacket passage, the gas exhaust manifold of motor is lowered the temperature, extend the working life of gas exhaust manifold.
The tube wall of engine cooling water manifold passage 3 and the tube wall of exhaust passage 1 do not coincide, and avoid heat to transmit too fast.The tube wall of jacket passage 2 and the tube wall of engine cooling water manifold passage 3 have common sparing, and partly enclosing of 0 ~ 360 ° of angle of engine cooling water manifold passage is as shown in Figure 2 covered; Or engine cooling water manifold passage is located in the cavity of jacket passage, layout is covered in entirely enclosing of 0 ~ 360 ° of angle of engine cooling supply mains as shown in Figure 3.Both structures are all simple, reduce overall dimensions specification, compact attractive in appearance, are convenient to mounting arrangements.
Cooling water in engine cooling water manifold passage 3 is that reverse cooling is lowered the temperature, and in the advanced cylinder head of cooling water, then enters cooling in cylinder block; Or the cooling water in engine cooling water manifold passage is that forward cooling is lowered the temperature, and in the first cylinder block of cooling water, then enters cooling in cylinder head.
Exhaust passage in the cavity of jacket passage 2 is one group that is arranged side by side, can for the two or four be arranged side by side, compact structure.
Motor, utilizes above-mentioned water jacket type gas exhaust manifold.The exhaust passage of water jacket type gas exhaust manifold is connected with the relief opening of motor.Compact structure, reduces engine component quantity.
By integrated engine cooling water manifold passage, realize engine tail gas waste-heat and reclaim, fast lifting Inner eycle water temperature, after greatly improving engine start, water temperature rises slow common fault, allows motor enter steady operating mode as early as possible.
The tube wall of engine cooling water manifold passage is provided with the electronic valve for being connected with jacket passage, and be provided with temperature transducer in engine cooling water manifold passage, electronic valve and temperature transducer are all connected with the control unit of motor.
When motor just starts, open electronic valve, allow the water temperature of motor inner cooling water rise faster, allow motor enter steady operating mode sooner; After temperature sensor senses reaches setting value to the cooling water temperature in engine cooling water manifold passage, control unit controls electronic valve and closes, and engine cooling water manifold passage normally works.
