The invention provides an engine cooling system which comprises a cooling water pump, a cylinder body water sleeve and a cylinder cover water sleeve. The engine cooling system further comprises a flow dividing device. An inlet of the flow dividing device is connected with an outlet of the cooling water pump, the flow dividing device at least comprises two outlets, at least one outlet is connected with the cylinder body water sleeve, and at least one outlet is connected with the cylinder cover water sleeve. By means of the engine cooling system, coolant flow of a cooling engine cylinder body and a cylinder cover can be accurately controlled, the different temperature requirements of the engine cylinder body and the cylinder cover are met, and an engine heat management system is well controlled. Meanwhile, the engine cooling system is easy to implement and optimize and low in cost.
Description
Technical field
The invention belongs to technical field of engines, relate to a kind of engine cooling technology.
Background technique
Present engine cooling system adopts cooling liquid to enter cylinder body water jacket after water pump supercharging more, then upwards flows into cylinder cover water jacket, then returns to water pump after thermostat and radiator.In order to improve the performance of motor, some motor has started to adopt two thermostat structures, control respectively the liquid circulation of cylinder body and cylinder cap, keep the temperature of cylinder body slightly higher than the temperature of cylinder cap, thereby reduce the friction of connecting rod, improve charging efficiency, reduce the tendency of pinking, given play to better the performance of motor.
Two thermostat Controlled cooling systems in cooling liquid after water pump supercharging, the water jacket of cylinder body and cylinder cap need be entered respectively, realizing the main flow that relies on the size in water jacket aperture to control cooling liquid in shunting, accurate control cannot be accomplished, optimize difficulty, cost is higher simultaneously.
Summary of the invention
The object of the present invention is to provide the engine-cooling system of a kind of center housing temperature of control engine comparatively exactly and cylinder cap temperature.
In order to achieve the above object, solution of the present invention is:
A kind of engine-cooling system, comprises cooling waterpump, cylinder body water jacket and cylinder cover water jacket, also comprises part flow arrangement; Wherein, the entrance of described part flow arrangement is connected with described cooling water delivery side of pump; Described part flow arrangement at least comprises two outlets, and described at least one, outlet connects described cylinder body water jacket, and described at least one, outlet connects described cylinder cover water jacket.
Described part flow arrangement is diverter valve.
Described cylinder body water jacket comprises cylinder body air inlet side water jacket and cylinder body exhaust side water jacket; Described part flow arrangement comprises three outlets; A described outlet connects described cylinder body air inlet side water jacket, and a described outlet connects described cylinder body exhaust side water jacket, and a described outlet connects described cylinder cover water jacket.
Owing to adopting such scheme, the invention has the beneficial effects as follows: engine-cooling system of the present invention is on existing pair of thermostat Controlled cooling system, in cylinder body water jacket front position, part flow arrangement is set, control the coolant rate that enters respectively cylinder body air inlet side water jacket, cylinder body exhaust side water jacket and cylinder cover water jacket, with the temperature of control engine cylinder body and cylinder cap more accurately, meet the different temperatures requirement of engine cylinder-body and cylinder cap, better control engine heat management system; Easily, cost is lower in the invention process, optimization simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of the engine cold system of the embodiment of the present invention.
In accompanying drawing: 1, cylinder hole; 2, cylinder body exhaust side water jacket; 3, enter the cooling liquid of cylinder cover water jacket; 4, diverter valve mounting point; 5, pump outlet; 6, cylinder body air inlet side water jacket; 7, cylinder body thermostat mounting point.
Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
The present invention proposes a kind of engine-cooling system, this system comprises cooling waterpump, cylinder body water jacket, cylinder cover water jacket and diverter valve; Wherein, cylinder body water jacket comprises cylinder body air inlet side water jacket and cylinder body exhaust side water jacket.Diverter valve comprises an entrance and three outlets, and its entrance is connected with cooling water delivery side of pump; In three outlets, one is connected with cylinder cover water jacket, and one is connected with cylinder body air inlet side water jacket, and one is connected with cylinder body exhaust side water jacket.Diverter valve is installed in cooling water delivery side of pump rear end, is controlled this diverter valve, thereby control the coolant rate of inflow engine cylinder body air inlet side water jacket, cylinder body exhaust side water jacket and cylinder cover water jacket, to reach the different temperatures requirement to cylinder body and cylinder cap.Be illustrated in figure 1 the structural representation of the engine-cooling system of the embodiment of the present invention; Wherein, arrow represents the flow direction of cooling liquid, and 1 is cylinder hole, and 2 is cylinder body exhaust side water jacket, and 3 is the cooling liquid that enters cylinder cover water jacket, and 4 is diverter valve mounting point, and 5 is pump outlet, and 6 is cylinder body air inlet side water jacket, and 7 is cylinder body thermostat mounting point.
Cooling liquid, after cooling waterpump, enters diverter valve.Regulate diverter valve, the coolant rate sum that control enters cylinder body air inlet side water jacket and cylinder body exhaust side water jacket is less than the coolant rate that enters cylinder cap, and the temperature that further auxiliary thermostat is realized cylinder body is higher than cylinder cap temperature.By regulating diverter valve, control the ratio of aforementioned three flows, thereby can more accurately control the temperature relation of cylinder body and cylinder cap.
Engine-cooling system of the present invention is on existing cooling system, especially on existing pair of thermostat cooling system, in cooling waterpump outlet port, diverter valve is set, control the coolant rate that enters respectively cylinder body air inlet side water jacket, cylinder body exhaust side water jacket and cylinder cover water jacket, with the temperature of control engine cylinder body and cylinder cap more accurately, meet the different temperatures requirement of engine cylinder-body and cylinder cap, better control engine heat management system; Easily, cost is lower for the invention process, optimization.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.Person skilled in the art obviously can easily make various amendments to these embodiments, and General Principle described herein is applied in other embodiments and needn't passes through performing creative labour.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not departing from improvement and the amendment that category of the present invention makes all should be within protection scope of the present invention.
