Connecting rod of internal combustion engine for changing compression ratio

The invention relates to a connecting rod (10) for an internal combustion engine. The connecting rod is provided with a device for changing the compression ratio (VCR). The connecting rod comprises aconnecting rod head (20) and a connecting rod pin (50). The connecting rod pin is supported relative to the connecting rod head (20) by means of an eccentric wheel (40), the connecting rod head (20) or the connecting rod pin comprises at least one oil chamber (25), the eccentric wheel (40) is provided with a bulge (42) extending into the oil chamber (25); or the eccentric wheel comprises at leastone oil chamber or limits the oil chamber, and the connecting rod head or the eccentric wheel is provided with a bulge extending into the oil chamber, so that the oil pressure in the oil chamber (25)applies force to the bulge (42) to change the eccentric wheel position of the eccentric wheel (40). 本发明涉及一种用于内燃机的连杆(10)，所述连杆具有用于改变压缩比(VCR)的装置，所述连杆包括连杆头(20)和连杆销(50)，所述连杆销借助偏心轮(40)相对于所述连杆头(20)支承，其中，所述连杆头(20)或所述连杆销包括至少一个油室(25)，并且所
