The utility model discloses a kind of engine cylinder cover of the double thermostat bases of band, concrete structure is：The front end of engine cylinder cover is provided with two thermostat bases, and O-ring seal is equipped with two bottom surfaces of thermostat and two mounting surfaces of thermostat base, and thermostat housing is arranged on the top of thermostat, and is bolted on engine cylinder and covers.Two thermostat temperature controls difference is 3 DEG C, and the first thermostat is opened in 82 DEG C of cycle fluid, fully open at 92 DEG C；Second thermostat is opened in 85 DEG C of cycle fluid, fully open at 95 DEG C.The temperature opened by thermostatic valve is different, prevents engine to be subcooled, it is also possible to the engine of cold conditions is quickly warmed up, it is ensured that engine can run in the case of optimum temperature.Apparatus structure is simple, compact, and thermostat base is designed in cylinder cap front end, is easy to the whole machine of engine to arrange, saves engine appearance and size, reduces body and vehicle difficulty of matching, and the structure is adapted to the extensive use on any engine.
Description
Technical field
The utility model belongs to engine components, and in particular to a kind of engine cylinder cover.
Background technology
The quality of engine-cooling system is to ensure the key that can engine normally run, because engine is suitable
Its performance that worked under state of temperature just obtains optimal embodiment, and the flow of cooling working medium used by system typically passes through in cylinder head
Thermostat be adjusted.Traditional engine cylinder cover designs a thermostat base, i.e., can only install a thermostat.This
The drawbacks of planting structure is the cooling working medium circular flow for being unable to precisely controlling system, and then it cannot be guaranteed that engine is in optimization
Worked under temperature conditions.If engine temperature is too low, the heat that a part of fuel is sent just necessarily is lost.And engine exists
Worked in the case of supercooling, combustion mixture can not burn very well, increase Fuel Consumption, machine oil viscosity in low temperature increases
Height, the frictional resistance of component movement increases, and power output will also be reduced.If proposing a kind of two cylinder caps of thermostat of band,
So that the temperature difference that two thermostatics valve are opened, had both prevented engine to be subcooled, while supercooled state engine can also be made
Warm up quickly, while fuel is saved, it is ensured that engine runs in the case of optimum temperature.
The content of the invention
The purpose of this utility model is to provide a kind of engine cylinder cover of the double thermostat bases of band, by installing two thermostats
Temperature adjustment is carried out, engine is realized most economical operation.
Theory structure of the present utility model is as follows with technical scheme：The engine cylinder cover of the double thermostat bases of band, with starting
Machine cylinder cap, O-ring seal, thermostat, thermostat housing, bolt and cycle fluid etc..The front end of engine cylinder cover is provided with two sections
Warm device seat, O-ring seal is equipped with two bottom surfaces of thermostat and two mounting surfaces of thermostat base, and thermostat housing is arranged on
The top of thermostat, and be bolted on engine cylinder and cover.
The thermostat base is designed in engine cylinder cover front end, is easy to whole machine to arrange and save appearance and size, reduces body
With vehicle difficulty of matching.
Its innovative point is compared with traditional cylinder cover：Cylinder cap is provided with two thermostat bases, it is therefore intended that have engine
Optimum operating temperature is interval.Preventing engine to be subcooled causes combustion instability, power drop, and fuel economy is poor, while
Lubricating oil viscosity can also increased, the serious consequences such as insufficient lubrication, parts wear aggravation are caused.Two thermostats are installed, are made
Its respective temperature control differs 3 DEG C, one high and one low, slow to adjust coolant temperature, and then prevents engine to be subcooled.
If engine coolant internal circulating load is relatively low, take away that heat is very few also to cause engine overheat so that gasoline engine produce it is early
Combustion, pinking ablation piston top.Can further make diesel injector gum deposit, overheat burn to death, cylinder cap thermal stress-cracking, inlet and exhaust valve
A series of problems, such as seat deformation and gas leakage ablation valve.Therefore, precision controlling cooling liquid temperature, reasonable distribution coolant is taken away
Heat becomes particularly important.
The characteristics of the utility model and beneficial effect are：It is used to install in two thermostat bases of engine cylinder cover Front-end Design
Thermostat, the temperature opened by two thermostatics valve is different, prevents engine to be subcooled, while starting for cold conditions can also be made
Machine is quickly warmed up, it is ensured that engine can run in the case of optimum temperature.The utility model simple structure, compact, section temperature
Device seat design is easy to the whole machine of engine to arrange in cylinder cap front end, saves engine appearance and size, reduces body and is matched with vehicle
Difficulty, the structure is adapted to the extensive use on any engine.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the utility model principle and structure.
Specific embodiment
Structure of the present utility model is described further below in conjunction with accompanying drawing and by embodiment.
The engine cylinder cover of the double thermostat bases of band, its structure is：The front end of engine cylinder cover 1 is provided with two thermostat base 1-
1st, 1-2, O-ring seal 2, thermostat housing are equipped with two bottom surfaces of thermostat 3-1,3-2 and two mounting surfaces of thermostat base
4 are arranged on the top of thermostat, and are fixed on engine cylinder by bolt 5 and cover.
Two thermostat temperature controls difference is 3 DEG C, and the first thermostat is opened in 82 DEG C of cycle fluid, whole at 92 DEG C
Open；Second thermostat is opened in 85 DEG C of cycle fluid, fully open at 95 DEG C.
By taking four-cylinder diesel engine as an example.Thermostat housing is fixed on engine cylinder and covers using the bolts assemblies of M8 × 25, passes through
Rubber sealing.The cycle fluid that cooling system is used is anti-icing fluid, when anti-icing fluid temperature reaches 82 DEG C, first thermostat valve
Door is opened, when anti-icing fluid temperature reaches 85 DEG C, second valve of thermostat 4.It is different by two thermostat opening temperatures, one
High one is low, the temperature of slow regulation cooling liquid.Both engine can have been prevented to be subcooled, while the engine of cold conditions can also be made very
Warm up soon, it is ensured that engine can run in the case of optimum temperature,
Using end spaces before engine cylinder cover, dexterously devising can be while installs 2 thermostats for the utility model
Thermostat base, effectively reduces the external volume of engine fuselage, the difficulty that engine is matched with vehicle is reduced, to vehicle
Matching leaves bigger assembly space.
