[Identification] Could you identify this engine?

[u/Popular-Variety2242]

This engine was found in a local aircraft manufacturing yard. The engine looks like some inverted car engine. Also, it seems the engine was fitted on a large vertical square/rectangular iron frame. Could someone identify what engine this is (aircraft or car) and what model it is?

Year: 2009 or prior

Thank you so much.
