Abstract:
PCT No. PCT/LU94/00001 Sec. 371 Date Sep. 19, 1995 Sec. 102(e) Date Sep. 19, 1995 PCT Filed Mar. 21, 1994 PCT Pub. No. WO94/21905 PCT Pub. Date Sep. 29, 1994An engine including an assembly of at least two cylinders with different displacements and two crankshafts coupled at the same rotational speed via a gear train and a variably timed transmission having three concentric shafts separable from the drive assembly and designed to reduce the compression ratio as the intake pressure increases. The maximum and minimum compression ratios are set within the angular displacement limits between the two cylinders, and between said two cylinders and the clearance space, so that (a) the start of the variably time transmission stroke increases the translation of the piston by units of angular displacement between the two crankshafts at the end of compression phase, and (b) the end of the variably time transmission stroke combines combustion gas expansion on the piston at least from the maximum torque on the crank of the short-stroke crankshaft.
