Problems solved by technology

When the engine is in a cold start condition, due to the low temperature of the intake system and the cylinder, it is difficult for the gasoline to evaporate completely, which will cause incomplete combustion and a large amount of hydrocarbon emissions. In addition, the temperature of the engine oil is low, the friction of the internal moving parts of the engine is relatively large, and the fuel consumption is also large; therefore, it is necessary to increase the warm-up speed as soon as possible, and at the same time increase the temperature rise speed of the engine oil

Abstract

The invention discloses a cooling system and a cooling method for an automobile engine. The automobile engine cooling system comprises a cylinder body, a cylinder cover, a water storage pot, a heat exchanging part, a radiator, engine oil coolers and a heat management module, wherein the heat management module is provided with a control valve, a normally-communicated cylinder cover water jacket connector, a water storage pot connector, an engine oil cooler connector, a cylinder cover water passing channel connector capable of adjusting a connecting area through the control valve, a heat exchanging part connector and a radiator connector. During a cold start, a connecting area of the cylinder cover water passing channel connector, the heat exchanging part connector and the radiator connectoris enabled to be zero; when the engine is heated, the connecting area of the cylinder cover water passing channel connector and the radiator connector is enabled to be zero, and the connecting area of the heat exchanging part connector is enabled to be 100 percent; and when temperature of the engine is in a high working state, the connecting area of the cylinder cover water passing channel connector, the heat exchanging part connector and the radiator connector is enabled to be 100 percent. According to the cooling system and the cooling method for the automobile engine, the heating speed ofthe engine and the engine oil heating speed can be increased, and the oil consumption can be reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and in particular relates to an automobile engine cooling system and a cooling method. Background technique [0002] Engine warm-up refers to the process in which the temperature of the engine body rises from low temperature to normal operating temperature. When the engine is in a cold start condition, due to the low temperature of the intake system and the cylinder, it is difficult for the gasoline to evaporate completely, which will cause incomplete combustion and a large amount of hydrocarbon emissions. In addition, the temperature of the engine oil is low, the friction of the internal moving parts of the engine is relatively large, and the fuel consumption is also large; therefore, it is necessary to increase the warm-up speed as soon as possible, and at the same time increase the temperature rise speed of the engine oil. Contents of the invention [0003] The object of the pres...
