A piston with external pins boss connected with at least two coupled crankshafts, transforming reciprocating linear movement of the piston into rotary motion of the crankshafts. A cylinder jacket with the piston head forms the combustion chamber. Piston inner space with static counterpart forms an additional intake-breathing chamber. On static counterpart, an income and outgo valves can be located. From reciprocating movement of the piston, the intake-breathing chamber will provide intake gases to the combustion chamber employing a transfer port. Previous to the transfer port, a control valve may be disposed to regulate the volume of intake gases entering the combustion chamber. The intake-breathing gases not used for combustion may be mixed with combustion exhaust gases. Length of connecting links, on inverse configuration, provides extra time at maximum compression rate; improving evaporation and combustion stage timing.

A compression ignition internal combustion engine (1), which includes a cylinder (2), a piston (3) reciprocably received within the cylinder (2), a pair of contra-rotating crankshafts (4, 5) rotatably mounted relative to the cylinder (2), a pair of connecting rods (6, 7) each having a first end (61, 71) connected to a crank journal (41, 51) of a respective one of the crankshafts (4, 5) and a second end (62, 72) connected to the piston (3). The engine (1) is configured such that the stroke of the piston (3) in a first direction toward the crankshafts (4, 5) causes each crankshaft (4, 5) to rotate by a first angle and the piston stroke in a second direction opposite the first direction causes each crankshaft (4,5) to rotate by a second angle different (β−α) from the first angle.
