Model utility content
For solving the deficiencies in the prior art, the utility model provides a kind of engine cylinder cover that is integrated with gas exhaust manifold water jacket that can be convenient to manufacture, and meanwhile, another object of the present utility model is to realize the independent of gas exhaust manifold water jacket to control.
For achieving the above object, the engine cylinder cover that is integrated with gas exhaust manifold water jacket of the present utility model, has:
Cylinder cover water jacket;
Gas exhaust manifold water jacket, is fixedly installed on cylinder cover water jacket top, and is communicated with cylinder cover water jacket by the first communication passage, is provided with total mouthful of water outlet on gas exhaust manifold water jacket.Gas exhaust manifold water jacket is arranged on to the top of cylinder cover water jacket, be convenient to whole manufacturing, simultaneously, between the two, by the first communication passage, be communicated with, in multi-cylinder structure, cooling liquid in the water jacket of each cylinder is independently circulated in gas exhaust manifold water jacket, has avoided the generation of interference phenomenon between the cooling liquid in multi-cylinder water jacket.
As to improvement of the present utility model, described gas exhaust manifold water jacket comprises water sleeve bottom, the top water jacket being interconnected, and described bottom water jacket is communicated with cylinder cover water jacket by the first communication passage; Top water jacket and bottom water put to be respectively equipped with and are communicated with top water cover water outlet and the bottom water cover water outlet arranging with the total mouth of water outlet.Gas exhaust manifold water jacket is divided into two parts that are interconnected, is convenient to, to entering the control of the cooling liquid in gas exhaust manifold, effectively raise cooling effect.
As the restriction to aforesaid way, described top water jacket is communicated with setting with bottom water jacket by the second communication passage vertically arranging.
As to improvement of the present utility model, at top water jacket and bottom water jacket, at least on one, be provided with automatically controlled throttle valve and temperature transducer.By setting up automatically controlled throttle valve and temperature transducer, can be when being positioned at the temperature of the cooling liquid of top water cover and bottom water jacket and detecting, according to the temperature detecting, by automatically controlled throttle valve, the coolant rate in the two is controlled, when realizing independent control of gas exhaust manifold, improved the cooling effect to gas exhaust manifold.
As the restriction to aforesaid way, described automatically controlled throttle valve and temperature transducer are arranged at least water outlet of one of top water jacket and bottom water jacket.
In sum, adopt the technical solution of the utility model, be convenient to the manufacture of gas exhaust manifold water jacket and cylinder cover water jacket, in addition, realized the independent of gas exhaust manifold water jacket controlled, improved cooling effect, it is simple in structure.

Embodiment
The engine cylinder cover that is integrated with gas exhaust manifold water jacket that the present embodiment relates to, from Fig. 1 in conjunction with shown in Fig. 2, it comprises cylinder cover water jacket 1, gas exhaust manifold water jacket 2, and gas exhaust manifold water jacket 2 is fixedly installed on cylinder cover water jacket 1 top, and is communicated with cylinder cover water jacket 1 by the first communication passage 3.On gas exhaust manifold water jacket 2, be provided with total mouthful 4 of water outlet.Wherein, take four cylinder engine as example, as shown in Figure 2, when every cylinder of four cylinder engine is that gas exhaust manifold water jacket 2 is communicated with, all there is independently the first communication passage 3.
By Fig. 3, in conjunction with shown in Fig. 4, in the present embodiment, gas exhaust manifold water jacket 2 comprises top water jacket 21 and bottom water jacket 22, and the two is communicated with and is arranged by the second communication passage 25 vertically arranging, and bottom water jacket 22 is communicated with cylinder cover water jacket 1 by the first communication passage 3; On top water jacket 21 and bottom water jacket 22, be respectively equipped with top water cover water outlet 23 and bottom water cover water outlet 24, together with top water cover water outlet 23 meets at bottom water cover water outlet 24, be communicated with for total mouthful 4 with water outlet.
In use, cooling liquid in cylinder cover water jacket 1 is in the first communication passage 3 flow into bottom water jacket 22, cooling liquid in wherein two cylinder bodies of multicylinder engine flow into bottom water jacket 22 interior after, by bottom water cover water outlet 24, directly flowed out, the cooling liquid of another two cylinder bodies flow into bottom water jacket 22 interior after, through the second communication passage 25, enter in top water jacket 21, cooling to top water jacket 21 after, have top water cover water outlet 23 to flow out.
In addition, at top water cover water outlet 23 and bottom water cover water outlet 24 places, be provided with respectively not shown automatically controlled throttle valve and temperature transducer, wherein, temperature transducer is for the temperature of the cooling liquid in water jacket is detected, and automatically controlled throttle valve regulates control for the flow of the cooling liquid circulation in water jacket.It can be controlled temperature transducer and automatically controlled throttle valve by vehicle ECU in use.Specifically, while operating when separately the automatically controlled throttle valve of top water cover water outlet and temperature transducer are controlled, temperature transducer detects the coolant temperature of top water cover water outlet, and according to the result detecting, regulate the aperture of automatically controlled throttle valve, to change the cooling liquid discharge value of top water cover water outlet, the final top water sleeving temperature of controlling, concrete control principle is that the temperature of cooling liquid in the top water jacket that temperature transducer records is during below or above desired value, control the aperture of automatically controlled throttle valve, reduce or increase the flow of cooling liquid, and the cooling liquid in water jacket is corresponding now, increases or reduce.In like manner, same as described above to the bottom water cover temperature transducer of water outlet 24 and the control of automatically controlled throttle valve.
In addition, when two groups of automatically controlled throttle valve and temperature transducer work simultaneously, when water jacket required coolant temperature desired value in top is greater than or less than the desired value of the required coolant temperature of bottom water jacket, can be by regulating corresponding automatically controlled throttle valve, to realize the two-way control to top water jacket and bottom water jacket.
