Abstract
An eccentric member for a system for varying compression ratio of an internal combustion engine comprises two circumferential bearing portions for bearing respective big ends of connecting rods of a V-type internal combustion engine. The bearing portions are eccentric with respect to an inner surface of the eccentric member and located at a distance from each other in axial direction of the eccentric member. The eccentric member also comprises two external gears between which the bearing portions are located. The eccentric member is made of two half-sleeves which are fixed to each other at least between the bearing portions.

An eccentric member for a system for varying compression ratio of an internal combustion engine, comprising:
- two circumferential bearing portions for bearing respective big ends of connecting rods of a V-type internal combustion engine, which bearing portions are eccentric with respect to an inner surface of the eccentric member and located at a distance from each other in an axial direction of the eccentric member, wherein the eccentric member comprises two half-sleeves which are fixed to each other at least between the bearing portions;
- and
- two external gears between which the bearing portions are located.
A V-type internal combustion engine including variable compression ratio, comprising:
- a crankshaft including a crankpin;
- two connecting rods including respective big ends and small ends;
- two pistons being rotatably connected to the respective small ends;
- an eccentric member rotatably mounted on the crankpin, the eccentric member comprising:
- two circumferential bearing portions for bearing respective big ends of the connecting rods, which bearing portions are eccentric with respect to an inner surface of the eccentric member and located at a distance from each other in an axial direction of the eccentric member, wherein the eccentric member comprises two half-sleeves which are fixed to each other at least between the bearing portions;
- and
- two external gears between which the bearing portions are located:
- and
- an auxiliary shaft having a gear mating with one of the external gears.
