The invention provides a cooling water circulating system for an automobile engine, belongs to the technical field of engines, and solves the problem of poor preheating effect of an existing engine preheating system. The cooling water circulating system for the automobile engine comprises an engine water jacket and a control device, wherein a water inlet of the engine water jacket is connected in series with a water pump; a water outlet of the engine water jacket is connected in series with a first electromagnetic valve; an insulated container, a communication pipeline and a radiator are arranged in parallel between a water inlet of the water pump and a water outlet of the first electromagnetic valve; water inlets of the insulated container, the communication pipeline and the radiator are connected with different control positions of the first electromagnetic valve; water outlets of the insulated container, the communication pipeline and the radiator are communicated with the water inlet of the water pump; and the control device is used for controlling the first electromagnetic valve according to the temperature of cooling water in the engine water jacket. The cooling water circulating system for the automobile engine has the advantages of only saving and utilizing the heat consumed in the environment without additionally consuming fuel, saving energy and protecting the environment.
Description
technical field [0001] The invention belongs to the technical field of engines, and relates to an engine cooling system, in particular to an automobile engine cooling water circulation system. Background technique [0002] Automobile originally refers to a transport vehicle powered by combustible gas, and also refers to a vehicle driven by its own equipment. An engine is a machine that can convert other forms of energy into another energy, usually chemical energy into mechanical energy. The power drive of the car is originally the engine. [0003] The cooling system of the engine is to ensure that the engine, transmission and other components work in the most suitable temperature environment. In order to reduce the heat dissipation of the engine cooling water, optimize combustion, and reduce mechanical wear, the most suitable working temperature of the engine is now in the range of 110-130°C . [0004] Running the engine below the optimal operating temperature will cause ...
