Abstract

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.
