Embodiment 1

[0024] Such as figure 2 An automobile engine cooling system provided by the present invention is shown, including a water pump 1, a cylinder head water jacket 5, a cylinder block water jacket 3, a first thermostat 11, a radiator 15, an electronic water pump 20, a supercharger 10, The expansion water tank 14, the oil cooler 13, the second thermostat 16, the heater 9 and the engine degassing pipeline 12, among which the corresponding pipelines of the oil cooler 13 and the heater 9 are opened and closed by the second thermostat 16 Control: After the engine is stopped, the supercharger 10 is cooled by the electronic water pump 20 with a delay; the flow rate of a loop is about 30L / min, while meeting the needs of the oil cooler 13 and the heater 9. The application of the second thermostat 16 in the above structure avoids unnecessary heat loss during the warm-up phase, enables the engine to quickly reach the operating temperature, improves combustion efficiency and reduces friction w...

Embodiment 2

[0029] An automobile engine cooling system provided by this embodiment, such as figure 2 As shown, the included equipment and the connection structure between the equipment are the same as the first embodiment.

[0030] When the engine is in the normal working phase, 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 pipeline is bypassed at the same time 17 is turned off, the coolant in the water pump is divided into two ways and enters the independent cylinder block water jacket 3 and the cylinder head water jacket 5 in a ratio of 3:7, and cools the cylinder block and cylinder head. Compared with the prior art , Cooling according to this ratio can achieve the best cooling effect, so that the cylinder block temperature is appropriately increased, thereby reducing friction, saving fuel consumption, and the cylinder head temperature is appro...

Embodiment 3

[0032] An automobile engine cooling system provided by this embodiment, such as figure 2 As shown, the included equipment and the connection structure between the equipment are the same as the first embodiment.

[0033] When the engine is stopped (ie 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 cooling of the supercharger 10, thereby The reliability of the supercharger 10 is ensured.

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 main function of the automobile engine cooling system is to take away the heat generated by the high-temperature parts of the automobile engine in time, and keep them working within the normal temperature range. The traditional engine cooling system usually consists of a water pump 1, a cylinder block water jacket 3 and a cylinder head water jacket 5, a first thermostat 11, a radiator 15, an expansion water tank 9, an oil cooler 13, and a supercharger 10. , The heater 9 is composed; the cylinder block water jacket 3 and the cylinder head water jacket 5 are designed in series. This structure makes the coolant pumped in the water pump 1 enter the cylinder block water jacket first through the cylinder block water jacket inlet 2 3. Then enter the cylinder head water jacket 5, so that the water temperature of the cylinder he...
