[0002] The structure of the rear air intake box of the 16V270 diesel engine is relatively complex, but its structure is compact. It has multiple chambers for high-temperature water, low-temperature water, and high-pressure air, as well as multiple mounting surfaces, including water pipe mounting surfaces, intercooler mounting surfaces, thermostatic valve box mounting surfaces, etc. It is difficult to cast and is prone to casting defects during casting. If there are casting defects inside the water cavity of the rear air intake box, it is not easy to find them. Water cavity leakage can easily lead to the interconnection of various systems in the rear air intake box, failure of some functions, shutdown of the diesel engine, water ingress into the cylinder, rust of some major components, and even more serious quality problems. Therefore, we need to test the air tightness of the water cavity of the rear air intake box of the diesel engine. During the test, the water cavity end of the air box needs to be sealed. The current sealing tooling is complicated to operate and requires a lot of physical labor.

[0003] Therefore, it is necessary to provide a new water cavity sealing device for a rear air intake box of a diesel engine and a method of using the same to solve the above-mentioned technical problems. Summary of the invention
