Mount apparatus for variable compression ratio internal combustion engine

摘要

An internal combustion engine 1 in which the compression ratio can be varied by moving a cylinder block and a crankcase along the axial direction of the cylinder is mounted on a vehicle body member 29 by at least two portions including a first mount portion 32 provided on a transmission apparatus to and a second mount portion 31 provided on the internal combustion engine 1 , wherein said second mount portion 31 is provided on the crankcase 4 . The first mount portion 32 and the second mount portion 31 are arranged in such a way that the direction of a rotation moment TD about the output shaft RC 1 of the transmission apparatus acting on the internal combustion engine 1 upon combustion becomes opposite to the direction of a rotation moment M 1 about the output shaft RC 1 generated by a force acting on a cylinder block 3 upon changing the compression ratio.
