Abstract
The present invention belongs to the technical field of diesel engines, and particularly relates to an engine cooling system and a cooling method therefor. In the engine cooling system of the present invention, when an engine needs to be warmed up, a first valve is opened, a lower engine body water storage chamber is in communication with an upper engine body water storage chamber, and some of the cooling water directly flows into the lower engine body water storage chamber from the upper engine body water storage chamber. The flow of the cooling water entering an engine body is reduced, and under the condition that heat dissipated by the engine is unchanged, the temperature rise of the cooling water flowing through the engine body such as a cylinder sleeve upper cooling water chamber and a cylinder sleeve lower water jacket is faster, such that an engine warming effect is improved.
