Embodiment 1

[0024] Such as figure 2 A kind of automobile engine cooling system provided by the present invention comprises water pump 1, cylinder head water jacket 5, cylinder body water jacket 3, first thermostat 11, radiator 15, electronic water pump 20, supercharger 10, Expansion water tank 14, engine oil cooler 13, second thermostat 16, heater 9 and engine degassing pipeline 12, wherein, the opening and closing of the corresponding pipelines of engine oil cooler 13 and heater 9 are controlled by second thermostat 16 Control; the supercharger 10 is cooled by the electronic water pump 20 after the engine stops; the flow rate of one circuit is about 30L / min, and the needs of the oil cooler 13 and the heater 9 are met at the same time. The application of the second thermostat 16 in the above structure avoids unnecessary heat loss during the warm-up period, makes the engine reach the working temperature quickly, improves combustion efficiency and reduces friction work, and saves fuel cons...

Embodiment 2

[0029] A kind of automobile engine cooling system provided by this embodiment, such as figure 2 As shown, the devices contained therein and the connection structure between the devices are the same as those in the first embodiment.

[0030]When the engine is in the normal working stage, the temperature has reached the opening temperature of the first thermostat 11 and the second thermostat 16, the first thermostat 11 and the second thermostat 16 are in the open state, and the bypass line 17 is closed, the coolant in the water pump is divided into two paths and enters the mutually independent cylinder body water jacket 3 and cylinder head water jacket 5 in a ratio of 3:7 to cool the cylinder body and cylinder head. Compared with the prior art , cooling according to this ratio can achieve the best cooling effect, so that the temperature of the cylinder block can be increased appropriately, thereby reducing friction, saving fuel consumption, and the temperature of the cylinder h...

Embodiment 3

[0032] A kind of automobile engine cooling system provided by this embodiment, such as figure 2 As shown, the devices contained therein and the connection structure between the devices are the same as those in the first embodiment.

[0033] When the engine is shut down (i.e., stopped), the oil pressure drops to zero rapidly, and the water pump 1 also stops working. At this time, the electronic water pump 20 enters the working state to provide circulating power for the coolant, and continues to delay the cooling of the supercharger 10, thereby The reliability of the supercharger 10 is guaranteed.

Abstract

The invention provides an automobile engine cooling system which comprises a water pump, a cylinder cover water jacket, a cylinder body water jacket, a first thermostat, a heat radiator, an electronicwater pump, a supercharger, an expansion tank, an engine oil cooler, a second thermostat, a fan heater and an engine degassing pipeline, wherein the opening and closing of corresponding pipelines ofthe engine oil cooler and the fan heater are controlled by the second thermostat; after the supercharger is shut down, the electronic water pump carries out delay cooling; and the flow rate of each loop is about 30 L / min, so that the requirements of the engine oil cooler and the fan heater are met at the same time. With the adoption of the engine cooling system, the friction is reduced, oil consumption is reduced, the requirement on water pump performance is lowered, the combustion efficiency is improved, and the reliability of the supercharger is ensured.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile engine cooling system. Background technique [0002] The function of the automobile engine cooling system is mainly to take away the heat generated by the high-temperature parts when the automobile engine is working, so as to keep them working within the normal temperature range. A traditional engine cooling system usually consists of a water pump 1, a cylinder block water jacket 3 and a cylinder head water jacket 5 connected in series, a first thermostat 11, a radiator 15, an expansion tank 9, an oil cooler 13, and a supercharger 10 , heater 9; cylinder water jacket 3 and cylinder head water jacket 5 are designed in series, this structure makes the coolant pumped by water pump 1 first enter the cylinder water jacket through the cylinder water jacket water inlet 2 3. Then it enters the cylinder head water jacket 5, so that the water temperature of the cylinder head is hi...
