It is installed between the supercharger and the intake manifold, and mainly functions to improve the scavenging efficiency of the engine. The intermediate cooler cools the pressurized air, helping the engine to inhale and burn fuel more effectively, thereby improving the performance and efficiency of the engine. Such a cooler can be water-cooled or air-cooled, depending on the design and application requirements. In the turbocharged vehicle, the intermediate cooler is particularly important, as it can significantly improve fuel economy and reduce exhaust emissions.

[0003] The emission system intercooler test tool is a device for testing the emission system intercooler.

[0018] Compared with the prior art, this utility model provides a test fixture for a system cooler in an emission system, which has the following advantages:

[0019] In the emission system cooler testing fixture, the drive extrusion cylinder is equipped with a product air inlet. An actuating extrusion ring is located on the outer side of the product air inlet. A telescopic connecting sleeve is located on the side of the actuating extrusion ring, and the telescopic connecting sleeve is rotatably connected to the actuating extrusion ring via a rotating shaft. A connecting auxiliary installation sleeve is located on the side of the telescopic connecting sleeve, and a compression rubber airbag ring is located on the inner side of the connecting auxiliary installation sleeve. An internal connecting vent pipe is located on the inner side of the compression rubber airbag ring. Rotating the actuating extrusion ring compresses the telescopic connecting sleeve, inflating the compression rubber airbag ring. The inflated compression rubber airbag ring presses the outer connecting pipe into a groove near the end of the product air inlet, securing it in place. Due to the high friction between the rubber and the pipe, slippage and detachment are prevented. The fixture is simple, convenient, and quick to install, effectively saving time and improving worker efficiency, thus enhancing the practicality of the emission system cooler testing fixture.
