Abstract
The invention discloses an engine cooling system and a cooling method. The cooling system comprises a water pump, a double-valve temperature regulator, a machine oil cooler, a water jacket of a cylinder body, a water jacket of a cylinder cover, a water tank radiator and an EGR cooler. The cooling system adopts a water passage circulation as follows: when the engine is started, the water pump begins to work; cooling liquid firstly flows into the machine oil cooler and enters in the water jacket of the cylinder cover to cool the key area of the cylinder cover, and then enters in the water jacket of the cylinder body from a gasket circulating hole of the cylinder cover to cool the cylinder body and the EGR cooler. The cooling liquid in the cooling system firstly cools the cylinder cover to reduce the temperature of the cylinder cover by 10 DEG C to 15 DEG C, enhance aeration efficiency, enlarge air inlet quantity, promote complete combustion, reduce the formation of discharge objects andenhance output efficiency; After cooling the cylinder cover, the cooling liquid enters in the cylinder body for cooling the cylinder body; the higher temperature of the cylinder body can reduce friction, improve fuel efficiency, enhance the output efficiency and reduce peak value pressure and temperature in the cylinder.
Description
Technical field
The invention belongs to automotive field, be applicable to enclosed Forced water cooling engine-cooling system.
Background technique
Existing engine-cooling system, normally cooling liquid enters cylinder block through water pump, enters thermoregulator again by cylinder cap again, carries out big short circle by thermoregulator, final waterback pump, concrete principle is seen Fig. 1; Or cooling liquid enters cylinder body and cylinder cap water jacket respectively by water pump, carries out big short circle by thermoregulator again, and final waterback pump is specifically seen Fig. 2.Only require that generally engine operating temperature can not be overheated, can not be cold excessively, but the temperature of cylinder cap is too high or be that the temperature of cylinder body is low slightly for the conventional engines methods for cooling.So not only influence the fuel consumption rate of motor and output power but also influence the discharging of motor.Along with the growth rapidly of present economy, the energy constantly consumes, and falls row and subtracts this target that has become whole world automobile industry to pursue of consumption.
Thereby guarantee that it is very important that motor always works in the best temperature range, and if center housing temperature is low excessively or the cylinder cap temperature is too high, not only influence the inefficiency of motor, and badly influence the exhaust emission of motor, cause energy waste simultaneously.
Summary of the invention
In order to address the above problem, the invention discloses a kind of engine-cooling system, comprise water pump, bivalve thermoregulator, machine oil cooler, cylinder body water jacket, cylinder cap water jacket, radiator of water tank and cooler for recycled exhaust gas, it is characterized in that, the water route circulation of described cooling system is: when engine start, water pump is started working, cooling liquid at first flows to machine oil cooler, enter the cylinder cap water jacket again, the key area of cylinder cap is cooled off, enter cylinder body water jacket by the gland shim opening, cool off, cool off to cooler for recycled exhaust gas again to cylinder body.
Further, when normal temperature, the paraffin in the thermoregulator is solid-state, and water inlet of radiator two-way is in the state that main valve is closed, auxiliary-valve is opened, and the thermoregulator main valve is in closed condition, and the cooling liquid of coming from radiator of water tank does not enter water pump and participates in circulation.
The invention also discloses the cooling means of motor.
Cooling liquid in the cooling system of the present invention is at first cooled off to cylinder head, can make the temperature of cylinder cap reduce by 10～15 ℃, especially cylinder cap bridge of the nose district is cooled off, and cylinder cap is worked under the temperature set-point of optimum.The cylinder head temperature is low can to improve charging efficiency, increases air inflow, can promote perfect combustion, reduces the formation of effulent, improves output power.Cooling liquid has been cooled off cylinder cap and has been entered cylinder body then and carry out cylinder body cooling, so just makes cylinder body that an individual more suitable chilling temperature is arranged.The higher meeting of block temperature reduces frictional loss, improves fuel efficiency, improves output power and reduces surge pressure and temperature in the cylinder.

Embodiment
Below in conjunction with accompanying drawing its embodiment is specifically described.
Fig. 4 visual representation the engine-cooling system water route of embodiment of the present invention connect.When engine start, water pump 1 is started working, cooling liquid is begun to circulate by water pump 1 pressurization, at first flow to machine oil cooler 7, enter the cylinder cap water jacket again, the key area of cylinder cap 3 is cooled off, enter cylinder body water jacket by the gland shim opening, cool off for cylinder body 2, cool off for EGR (exhaust gas recirculation) cooler 8, the paraffin when normal temperature in the thermoregulator 4 is solid-state again, and the two-way main valve that is in of radiator 5 water intakes is closed, the state that auxiliary-valve is opened, thermoregulator 4 main valves are in closed condition, can not enter water pump 1 from the cooling liquid of radiator of water tank 5 and participate in circulation.Cooling liquid in cylinder cap 3, cylinder body 2 water jackets is heated rapidly by water jacket, and in the extremely short time, the temperature of engine coolant machine oil was improved rapidly in the extremely short time, so also can improve greatly the engine warm-up time like this.When cylinder body 2 temperature raise, the inside paraffin of thermoregulator 4 is liquefy gradually, and its volumetric expansion overcomes initial tension of spring and promotes thermoregulator 4 main valves and move backward, opens backwater mouth gradually, when temperature reaches 85 degree when above, the main valve standard-sized sheet of thermoregulator 4.Under the pumping action of water pump 5, the cooling liquid in the radiator of water tank 6 just enters in the engine cylinder cover 3 whole water jackets, makes the temperature cooling of cylinder cap 3, guarantees in suitable ideal temperature scope work.
Cooling system among the present invention can guarantee the temperature work of engine cylinder cover 3 each several parts at optimum, and it is maximum that the whole efficiency of cooling system can reach.When improving effective engine power, also reduce the pollution from exhaust emission that motor causes environment greatly, and fuel saving effectively.
