Unknown component near engine

I found a mechanical component near the engine as shown in the picture. It has a ring shape on the top and feels like made by stainless steel. There is no electric wire attached to it. There are two of them sit on the upper right and lower left of the engine. Does anyone know what’s the name of it and what’s the purpose of this component? My car is 2015 Hyundai Sonata. Thanks a lot!

Pretty sure those are just for lifting the engine, and not stainless steel.


Ahh! Never thought of this. Thank you!
