Embodiment 1

[0034] The engine cooling system provided by this embodiment, such as Figure 2 to Figure 4 As shown, it includes a cylinder head cooling circuit, a cylinder block cooling circuit and valve parts; the cylinder head cooling circuit is used for heat exchange with the cylinder head 11 of the engine 1; the cylinder block cooling circuit is used for heat exchange with the cylinder block 12 of the engine 1; The cooling circuit of the head and the cooling circuit of the cylinder body are connected through the valve. When the temperature of the coolant in the cooling circuit of the cylinder body is lower than the first preset temperature, the valve controls the cooling circuit of the cylinder head to be disconnected from the cooling circuit of the cylinder body; When the temperature of the coolant in the cooling circuit is greater than or equal to the first preset temperature, the valve element controls the cylinder head cooling circuit to communicate with the cylinder block cooling ci...

Embodiment 2

[0058] The automobile provided in this embodiment includes the engine cooling system described in Embodiment 1. The engine cooling system includes a cylinder head cooling circuit, a cylinder block cooling circuit and valve parts; the cylinder head cooling circuit is used for exchanging heat with the cylinder head 11 of the engine 1; the cylinder block cooling circuit is used for exchanging heat with the cylinder block 12 of the engine 1 The cylinder head cooling circuit is communicated with the cylinder block cooling circuit through a valve, and when the coolant temperature in the cylinder block cooling circuit is lower than the first preset temperature, the valve controls the cylinder head cooling circuit to disconnect from the cylinder block cooling circuit. When the car is cold started, when the temperature of the coolant in the cylinder block cooling circuit is lower than the first preset temperature, the valve controls the cylinder block cooling circuit and the cylinder he...

Abstract

The invention provides an engine cooling system and an automobile, and relates to the technical field of the automobile. The engine cooling system comprises a cylinder cover cooling loop, a cylinder block cooling loop and a valve, wherein the cylinder cover cooling loop is used for exchanging heat with a cylinder cover of an engine; the cylinder block cooling loop is used for exchanging heat witha cylinder block of the engine; the cylinder cover cooling loop communicates with the cylinder block cooling loop through the valve; and when the temperature of cooling liquid in the cylinder block cooling loop is lower than a first preset temperature, the valve is used for controlling the cylinder cover cooling loop to be disconnected from the cylinder block cooling loop. When the automobile is in cold start, the temperature of cooling liquid in the cylinder block cooling loop is lower than the first preset temperature, the valve is used for controlling the cylinder block cooling loop to be disconnected from the cylinder cover cooling loop, so that the cylinder block cooling loop and the cylinder cover cooling loop are independent of each other; the cooling liquid in the cylinder block cooling loop exchanges heat with the cylinder block and can quickly rise to an appropriate temperature, so that the engine can quickly reach the normal operating temperature.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an engine cooling system and an automobile with the engine cooling system. Background technique [0002] The function of the automobile engine cooling system is to keep the engine in a proper temperature range under various working conditions. The engine cooling system should not only prevent the engine from overheating, but also prevent the engine from being too cold. If the engine is overheated, it will cause a decrease in charging efficiency, abnormal combustion, deterioration of the engine oil, ablation, and increased friction and wear of parts; if the engine is too cold, it will cause Gasoline engine mixture is poorly formed, engine oil will be excessively diluted by fuel and other problems. And after the engine is cold started, the engine cooling system must ensure that the engine heats up quickly and reaches the normal operating temperature as soon as possible. [00...
