The invention discloses a measuring device and method for the air content in the coolant of the engine. The measuring device comprises: a water outlet pipe, one end of which communicates with one end of the water chamber of the engine, and a first small circulation interface is arranged in the middle of the water outlet pipe; The water inlet pipe, one end of which communicates with the other end of the water cavity of the engine, and the middle part of the water inlet pipe is provided with a second small circulation interface; the two ends of the radiator communicate with the other end of the water outlet pipe and the other end of the water inlet pipe respectively; the small circulation The two ends of the water pipe communicate with the first small circulation interface and the second small circulation interface respectively; the thermostat is arranged on the first small circulation interface; the transparent observation cover is fixed on the highest point of the water outlet pipe and Between the water outlet of the engine and the first small circulation interface, limit value warning lines and multiple scale lines are arranged on the outer surface of the observation cover. The measuring device has the advantages of simple structure, low manufacturing cost and convenient use, and can quickly and accurately read the volume of the air in the cooling liquid, and is convenient for calculation.
Description
technical field [0001] The invention relates to the field of engines, in particular to a device and method for measuring the air content in engine coolant. Background technique [0002] When the cooling system of the engine is working normally, there are few air bubbles inside it, and even if some air bubbles are produced, they can be quickly released through the degassing system of the cooling system, such as the expansion tank. In actual use, due to the failure of the coolant (such as the deterioration of the coolant or the user’s continuous filling of water or the use of counterfeit and inferior coolant, etc.), the failure of the cooling system components (such as the failure of the pressure cap of the expansion tank, incorrect installation of the cooling pipeline, There are gaps in the cooling pipeline that cause air to enter, etc.) and other reasons, the air content of the coolant will gradually increase, causing problems in the normal cooling system, such as air resist...
