Abstract

The invention discloses a cylinder cooling structure for low-temperature start of an engine. The cylinder cooling structure comprises a water tank and a cylinder cover body, wherein the water tank and the cylinder cover body are connected through a diversion pipe. The diversion pipe is provided with a heating cavity and an electric check valve. The electric check valve is located between the heating cavity and the cylinder cover body. The heating cavity is further internally provided with a heating device and a temperature sensor. A machine body temperature sensing module is arranged on the surface of the cylinder cover body. The cylinder cooling structure further comprises a controller. The heating device, the electric check valve, the temperature sensor and the machine body temperature sensing module are each connected with the controller. The temperature sensor acquires the water temperature information in the heating cavity and transmits the water temperature information to the controller. The machine body temperature sensing module acquires the machine body temperature information of the surface of the cylinder cover body and transmits the machine body temperature information to the controller. By means of the cylinder cooling structure, the aim of providing a portable structure which is suitable for low-temperature environments in severe winter and is capable of preventing the cylinder cover body from cracking is achieved.

Description

technical field [0001] The invention relates to the field of engine cooling, in particular to a cooling structure for an engine low-temperature starting cylinder. Background technique [0002] The cylinder head is the cover of the engine and the parts that close the cylinder, including the water jacket, valves and cooling fins. The cylinder head is made of cast iron or aluminum alloy. It is the installation base of the valve mechanism and the sealing cover of the cylinder. The cylinder and the top of the piston form the combustion chamber. Many have adopted a structure in which the camshaft support seat and the tappet guide hole seat and the cylinder head are cast as one. [0003] In winter, when the temperature is low, the cylinder head of a diesel engine is prone to cracks and leaks. Therefore, in order to prevent the cylinder head from shrinking suddenly during the cooling process of the engine and causing cracks, in the prior art, warm water is usually added to the wate...
