Zusammenfassung:	The engine high-strength bolt connecting device comprises a high-strength bolt which penetrates through a through hole of a first connecting piece and is in threaded connection with a second connecting piece, a nut in threaded connection with the high-strength bolt is arranged above the first connecting piece, and the high-strength bolt is sleeved with a pressure detection piece located between the nut and the first connecting piece. The nut is provided with a pushing device used for providing pre-tightening force for the high-strength bolt by pushing the pressure detection piece, and the magnitude of the pre-tightening force is monitored in real time through the pressure detection piece. According to the utility model, the defects existing when the high-strength bolt is connected by using a hydraulic stretcher are overcome, the requirement on installation space is low, no special tool is needed, the disassembly and assembly time required by the special tool is saved, the jacking force is pure axial, the high
