[0025] Advantageously, an adjustment means is provided for adjusting the angular phase shift between said
compression piston and said expansion piston versus the operation conditions of the engine.
[0026] In particular, said crankshaft mechanism comprises a single drive shaft that operates said compression
piston and said expansion piston.
[0027] Alternatively, said crankshaft mechanism comprises a first drive shaft that operates said expansion
piston and a second drive shaft that operates said compression piston, said first and second drive shaft being
connected to each other such that they maintain a same speed of rotation.
[0028] In a possible exemplary embodiment, said crankshaft mechanism of said pistons of said compression cylinder and of said expansion cylinder is of the type master connecting rod-link rod.

[0041] Furthermore, engine 100 comprises a means for causing an open and close movement of transfer valve
4 at predetermined moments of the alternative cycle of pistons 1/7, in particular in phases respectively in the
compression in compression cylinder 2, and in the expansion in expansion cylinder 6.
[0042] In addition, a means is provided for causing an open and close movement of exhaust valve 9 at predetermined moments of the alternative cycle of pistons 1/7, as described below in detail.
[0043] In particular, the means for causing an open and close movement of transfer valve 4 and the means
for causing the open and close movement of exhaust valve 9 and of intake valve 3, comprises for example a
mechanism that comprises a cam shaft (not shown) that receives an actuating movement by crankshaft mechanism 20 and allows a suitable phasing of the alternated movement of two pistons 1/7, with the open and close movement of valves 3/4 and 9. In particular, crankshaft mechanism 20 comprises a single shaft 21 that operates by means of crank members 1a and 7a respective pistons 1 and 7, as shown in Figs. 1, 2 and 4. In a possible exemplary embodiment, crankshaft mechanism 20 of pistons 1 and 7 is of the type master connecting rod-link rod.
