ABSTRACT:
The invention concerns an internal-combustion engine, the engine comprising an engine housing having a first wall delimiting a first combustion chamber, a first connecting rod having a first piston and a second connecting rod having a second piston. The pistons also delimit the first combustion chamber. The first wall defines at least a section of a torus, and the pistons are guided along a curved path defined by the section of the torus. The connecting rods are coupled to an intermediate member, which travels bi-directionally between two end positions and the intermediate member is coupled to a crankshaft.
