Description

Technical Field

[0001] The utility model relates to the technical field of engine testing, in particular to an engine testing coolant circulation device. Background Art

[0002] The engine must undergo bench testing before leaving the factory. During the bench testing, the engine must be cooled. Currently, the engine tray is generally directly connected to the water channel of the test bench, and tap water is directly used for testing. This will cause rust in the water cavity of the engine, seriously affecting the effect of adding antifreeze to the engine in the future. In order to prevent rust in the water cavity, anti-rust liquid is generally used as coolant in engine bench testing.

[0003] When the existing engine test machine is undergoing bench testing, the cooling water is usually not cooled enough during the circulation process, and may be re-injected into the engine test machine before it is completely cooled. This makes the bench test result inaccurate, affecting the accuracy of the test. In addition, the cooling water circulation speed is low, which affects the working efficiency of the engine and brings certain adverse effects to people's use process. In order to address the deficiencies of the existing technology, we propose an engine test machine coolant circulation device. Utility Model Content
