ABSTRACT:
An internal combustion engine presenting a number of cylinders, each defined by a respective axially symmetrical cavity formed in the engine block, and each defining, together with a piston sliding axially inside the cylinder and a head connected to the block, a combustion chamber served by a supply system on the head; the cylinders being divided into a first and second group, each composed of pairs of first and second cylinders arranged in a V and converging towards a respective drive shaft for each group; and the two groups being connected inverted and facing each other, so that the first and second cylinders in each pair of cylinders in the first group are connected at the respective head end so as to form a V with respective first and second cylinders in each corresponding pair of cylinders in the second group, and so that each pair of first cylinders in the two groups defines a first combustion chamber, and each pair of second cylinders in the two groups defines a second combustion chamber common to the respective pistons.
