p-301 BPA CRANKSHAFT PHASING MECHANISM Abstract A variable compression ratio engine has a pair of crankshafts connected by a phase adjuster mechanism operative to change the phase angle between the crankshafts so as to vary the compression ratio of the engine. The phase adjuster mechanism includes two pairs of helical phasing gears. Each of those pairs consists of a gear fixedly mounted on a crankshaft and, operatively engaged therewith, a gear fixedly mounted on an axially movable adjuster member. The crankshafts can be arranged in-line or side-by-side in parallel. Each of the phasing gears which is fixedly connected to the axially movable adjuster member is bounded by a respective imaginary cylindrical surface whose axis coincides with and whose points are equidistant from the axis of rotation of the adjuster member, and whose diameter is equal to the outside diameter of that phasing gear, and which extends across the length of the engine block without intersecting the envelope swept by each crankshaft and connecting rod means associated with that crankshaft whereby the phasing gears of the phase adjuster mechanism are operable P-301 BPA along the whole length of the engine block so as to minimize the length of each of the crankshafts and, ultimately, the external lengthwise dimensions of the engine.
