Core of the present utility model is to provide a kind of cylinder cover component of engine, reduces and wastes.It is in addition, of the present utility model
Another core is to provide a kind of engine with above-mentioned cylinder cover component.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As Figure 1-Figure 5, the utility model discloses a kind of cylinder cover component of engine, including cylinder cap and installed in cylinder
The thermostat covered, wherein, there is the runner for coolant circulation, and the entrance 1 of runner is used for and water pump inside the cylinder cap
Water side connection, runner outlet be used for be connected with the water inlet end of water pump；Thermostat has regulation close to one end of radiator
The main valve 3 of channel sized between cylinder cap and radiator, the one end of thermostat away from radiator have the outlet of regulation runner big
Small auxiliary-valve 4.The application in cylinder cap by setting runner and passing through the control of thermostat and main valve 3 and auxiliary-valve 4
Realize the flow direction of coolant.Due to being provided with the runner for coolant circulation in cylinder cap, when the temperature of coolant is not reaching to section
During warm device opening temperature, coolant is circulated between water pump and runner by auxiliary-valve 4, do not enter radiator；Work as coolant
Temperature reach the opening temperature of thermostat but when auxiliary-valve 4 does not have fully closed, a coolant part is by auxiliary-valve 4, in partial circulating
Water pump is flowed into passage, another part flows into water pump by main valve 3 by radiator；Make when coolant temperature continues rise
When thermostat auxiliary-valve 4 is fully closed, by the main valve 3 of thermostat, water pump all is flowed to by radiator for coolant.So can be with
The temperature of engine cylinder cap and cylinder block is rapidly reached operating temperature, heat engine speed can be accelerated, not only reduce fuel
Consumption, also reduces exhaust emissions.
As shown in figure 1, during engine cold, the thermostat housing bore closure of thermostat, i.e. main valve 3 are closed, coolant by
The water side of water pump enters the runner of cylinder cap through entrance 1, and the outlet flowed in runner and pass through runner is through water at auxiliary-valve
The water inlet end of pump flows back to water pump, realizes partial circulating.
As shown in Fig. 2 the temperature of engine is gradually increasing, thermostat is from when just reaching between standard-sized sheet, i.e., main valve 3 is by firm
When being opened into complete opening, now, auxiliary-valve 4 is also open mode, and coolant is entered the runner of cylinder cap by the water side of water pump,
Because main valve 3 and auxiliary-valve 4 are opening, a part of coolant then goes out through being exported to water pump from auxiliary-valve 4, and another
Part cooling also then passes through the inflow radiator of main valve 3.The mode set in the application is that main valve 3 is while opening
Promote auxiliary-valve 4 to move, i.e., it is in above process, cold as the increase of the aperture of main valve 3, the aperture of auxiliary-valve 4 are gradually reduced
But the partial circulating of liquid and systemic circulation exist simultaneously.
As shown in figure 3, the temperature of engine is higher, the auxiliary-valve 4 of thermostat completely closes, and the main valve 3 of thermostat
Open completely, at this moment coolant carries out, into radiator, carrying out systemic circulation by runner from main valve 3, and due to the pass of auxiliary-valve 4
Close so that partial circulating is closed.
In specific embodiment, cylinder cap has the entrance 1 of multiple runners, i.e., multiple through holes are offered on cylinder cap, these
Through hole is with the flow passage in cylinder cap, and these entrances 1 are connected with the water side of water pump.For entrance 1 number and
The size and shape of position and entrance 1 can be configured according to different needs, and in protection domain.
Main valve 3 and auxiliary-valve 4 in the application are linkage valve, when the aperture of main valve 3 gradually increases, auxiliary-valve
4 aperture is gradually reduced, i.e., when the aperture of the passage between cylinder cap and radiator gradually increases, the water inlet end and runner of water pump
Between the aperture of outlet be gradually reduced.
In practice, also main valve 3 and auxiliary-valve 4 can individually be controlled, i.e., the aperture of independent control bound door 3 gradually increases
Greatly, and at the same time individually the aperture of control auxiliary-valve 4 is gradually reduced.
In further embodiment, the cylinder cap has the cavity 2 with flow passage, and the outlet of runner is arranged on cavity
On 2, auxiliary-valve 4 realizes the regulation of the outlet size to runner by adjusting the break-make of runner and cavity 2.This application provides one
Concrete structure in kind of cylinder cap, the cavity 2 of setting is relative with the auxiliary-valve 4 of thermostat, and by auxiliary-valve 4 realize runner 1 with
The break-make of cavity 2, reach the control to coolant flow direction, specifically, by adjusting between the valve plate of auxiliary-valve 4 and cavity 2
Distance realizes the break-make of runner and cavity 2.It can be set for the shape of cavity 2 from size according to different needs, and
In protection domain.
In further embodiment, the cylinder cap has two spark plug mounting holes 5, in each spark plug mounting hole 5
One spark plug 6 is installed, specifically, in the range of the entrance 1 that two fiery piston mounting holes 5 are respectively positioned on runner is connected to form
Portion.It is not specifically limited herein for the concrete arrangement of spark plug mounting hole 5.
In addition, disclosed herein as well is a kind of engine, including cylinder cover component, wherein, the cylinder cover component is real as described above
The cylinder cover component disclosed in example is applied, therefore, the engine with the cylinder cover component is also with above-mentioned all technique effects, herein not
