Abstract
The utility model relates to a kind of cylinder cover water jacket, comprise cylinder cap body, described cylinder cap body rear end is relatively provided with the first cylinder bolt hole and the second cylinder bolt hole, and described cylinder cap body front center is provided with cooling water chamber, and described cooling water chamber lower portion is provided with air outlet flue; Described cooling water chamber is communicated with main water outlet and side water outlet, and wherein said main water outlet is between described first cylinder bolt hole and the second cylinder bolt hole, and described side water outlet is positioned at the side near described air outlet flue below described main channel.Cylinder cover water jacket of the present utility model effectively can reduce engine exhaust temperature, reduces the discharge of engine fuel consumption and NOx harmful gas, and then promotes engine performance.
Description
Technical field
The utility model belongs to the technical field of Engine Parts structural design, and in particular, the utility model relates to a kind of cylinder cover water jacket.
Background technique
The all outlet of the common cylinder head water jacket of prior art is all between two cylinder bolts of cylinder cap rear-most end, and the water-flow equation in water jacket is difficult to adjustment; When the air outlet flue of cylinder cap needs strengthening to cool, be subject to the restriction of this structure, it is not enough that exhaust duct of cylinder cover there will be cooling, causes engine exhaust temperature too high, and then affect the performance of motor.
Model utility content
In order to solve above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of cylinder cover water jacket.
To achieve these goals, the utility model have employed following technological scheme:
A kind of cylinder cover water jacket, comprise cylinder cap body, it is characterized in that: described cylinder cap body rear end is relatively provided with the first cylinder bolt hole and the second cylinder bolt hole, described cylinder cap body front center is provided with cooling water chamber, and described cooling water chamber lower portion is provided with air outlet flue; Described cooling water chamber is communicated with main water outlet and side water outlet, and wherein said main water outlet is between described first cylinder bolt hole and the second cylinder bolt hole, and described side water outlet is positioned at the side near described air outlet flue below described main channel.
Wherein, described cooling water chamber and between described main water outlet and side water outlet, there is collapsed configuration.
Wherein, the cross-section area of described main water outlet is greater than the cross-section area of side water outlet.
Compared with prior art, cylinder cover water jacket described in the utility model has following beneficial effect:
Cylinder cover water jacket of the present utility model effectively can reduce engine exhaust temperature, reduces the discharge of engine fuel consumption and NOx harmful gas, and then promotes engine performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cylinder cover water jacket of embodiment 1.
Embodiment
Be further elaborated cylinder cover water jacket described in the utility model below with reference to specific embodiment, to help, those skilled in the art conceives model utility of the present utility model, technological scheme has more complete, accurate and deep understanding.
Embodiment 1
As shown in Figure 1, cylinder cover water jacket described in the present embodiment, comprise cylinder cap body 1, described cylinder cap body 1 rear end is relatively provided with the first cylinder bolt hole 3 and the second cylinder bolt hole 7, described cylinder cap body front center is provided with cooling water chamber 8, and described cooling water chamber 8 bottom is provided with air outlet flue 2; Described cooling water chamber 8 is communicated with main water outlet 6 and side water outlet 4, described cooling water chamber 8 and have collapsed configuration 9 between described main water outlet 6 and side water outlet 4.Wherein said main water outlet 6 is between described first cylinder bolt hole 3 and the second cylinder bolt hole 7, water outlet position, described side 4 is near the side of described air outlet flue 2 below described main channel 6, and the cross-section area of described main water outlet is greater than the cross-section area of side water outlet.Cooling water flow 5 flows through main water outlet 6 and side water outlet 4 respectively.Water jacket water outlet is divided into two by the cylinder cover water jacket of the present embodiment, wherein most one of them water outlet of major general moves to outside two cylinder bolt holes, effective adjustment cooling water flow distribution, makes the cooling effect of air outlet flue improve, thus reaches the object reducing delivery temperature.After the cylinder cover water jacket of the present embodiment being applied to three cylinder engine in upright arrangement strengthening cooling, minimum specific fuel consumption is reduced to 240g/kWh by 250g/kWh, and Peak torque brings up to 74Nm by 70Nm.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
Claims (3)
