The invention discloses a measuring equipment for the air content in cooling liquid of an engine and a method, and the measuring equipment comprises a discharging tube, an inlet tube, a radiator, a small circulating water pipe, a thermostat and a transparent observation cover, wherein one end of the discharging tube is communicated with one end of a water cavity of the engine, and a first small cycle interface is arranged at the middle part of the discharging tube; one end of the inlet tube is connected with another end of the water cavity of the engine, and a second small cycle interface is arranged at the middle part of the inlet tube; two ends of the radiator are respectively communicated with the other end of the discharging tube and the other end of the inlet tube; two ends of the small circulating water pipe are communicated with the first small cycle interface and the second small cycle interface; the thermostat is arranged at the first cycle interface; the transparent observation cover is fixed at the highest point of the discharging tube, is located between a water outlet of the engine and the first small cycle interface, and a limiting value warning line and multiple scale lines are arranged on the outside face of the transparent observation cover. The measuring equipment is simple in structure, low in manufacturing cost, and convenient in usage, the volume of air in the cooling liquid can be read quickly and the calculation is convenient.
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 the engine coolant. Background technique [0002] When the cooling system of the engine is working normally, there are few bubbles inside it. Even if some bubbles are generated, they can be quickly released through the degassing system of the cooling system such as an 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 fake low-quality coolant, etc.), the failure of the cooling system components (such as the failure of the expansion tank pressure cap, the incorrect installation of the cooling pipeline, There are gaps in the cooling pipeline, causing air to enter, etc.). The air content of the coolant will gradually increase, causing problems in the normal cooling system, such as air resistance (air accumulates in the channel of the w...
