The invention relates to a reciprocating engine (1) in a motor vehicle, comprising a coupling arrangement (27) for transmission of a torque, from a crank shaft end (13), to a crank shaft flange (17) supported in a cylinder block, the crank shaft end (13) b...

A compression ratio altering device is for an engine with a cylinder block (1), cylinder head (1a), crankshaft (2) with crank (2b), reciprocating piston (4) and connecting rod (3) linked to a crankshaft journal (2c) at one end, and to the piston and the ot...

The invention relates to an internal combustion engine, which comprises a engine block (1) with at least one cylinder (3), and a crankshaft (5) having at least a crank (6) and being rotatably supported within the engine block. The piston (4) is reciprocate...

Pistons, each having an upper dead center position, are accommodated for reciprocating motion in respective cylinders. The upper dead center position of each piston is altered to vary engine compression ratio by setting drive for turning setting shaft (11)...
