Abstract
The present variable compression ratio V-type internal combustion engine is a variable compression ratio V-type internal combustion engine which joins cylinder blocks of two cylinder groups and makes the joined cylinder block move relatively to a crankcase, wherein the engine is provided with a first relative movement mechanism which is fastened to a first cylinder group side of the joined cylinder block through a plurality of supports and a second relative movement mechanism which is fastened to a second cylinder group side of the joined cylinder block through a plurality of supports. The number of the supports in each of the first relative movement mechanism and the second relative movement mechanism is made at least a number greater by exactly one than the number of cylinders of the first cylinder group and the second cylinder group, respectively.
