Abstract: The present invention relates to a system and a method for controlling coolant in a vehicle engine which stores heat by holding some coolant in an additional heat storage member when turning off the engine after heating the engine and which quickly warms up the engine using heat-containing coolant at the time of cold start. For this, the invention provides the system and method for controlling coolant in the vehicle engine which comprise a heat storage container and a coolant circulation control unit. The heat storage container made of insulation materials is connected to a coolant circulation line of a cylinder head to be opened and closed. The coolant circulation control unit provides the coolant in the heat storage container to the coolant circulation line of the cylinder head when the temperature of the cylinder head is lower than the temperature of the coolant in the heat storage container after turning off the engine and supplies the coolant in the coolant circulation line of the cylinder head to the heat storage unit when the temperature of the coolant in the coolant circulation line is below a certain value at the time of cold start.

Abstract translation: 本发明涉及一种用于控制车辆发动机中的冷却剂的系统和方法，该系统和方法通过在加热发动机之后关闭发动机时将一些冷却剂保持在额外的蓄热构件中来储存热量，并且使用含热量 冷启动时的冷却液。 为此，本发明提供了一种用于控制车辆发动机中的冷却剂的系统和方法，其包括储热容​​器和冷却剂循环控制单元。 由绝缘材料制成的储热容器连接到气缸盖的冷却剂循环管线以被打开和关闭。 当冷却液循环控制单元在关闭发动机之后，当气缸盖的温度低于蓄热容器中的冷却剂的温度时，将冷却剂在蓄热容器中提供给气缸盖的冷却剂循环管线， 当冷启动时冷却剂循环管线中的冷却剂的温度低于一定值时，将气缸盖的冷却剂循环管路中的冷却剂冷却至储热单元。
