Figures 10a and 10b are showing the superposed diagrams of an engine with a ratio of 5 between the displacements of the paired cylinders

Said diagrams showing the compression ratios per degree of angular rotation of the long-stroke crankshaft in the compression and expansion phases without ignition, in the start-of-travel and end-of-travel positions of the variably timed transmission, with the corresponding volumetric efficiencies.

Figures 11a and 11b are showing the superposed diagrams of an engine with a ratio of 2.5 between the displacements of the paired cylinders.

Said diagrams showing the compression ratios per degree of angular rotation of the long-stroke crankshaft in the compression and expansion phases without ignition, in the start-of-travel and end-of-travel positions of the variably timed transmission, with the corresponding volumetric effeciencies.
