Abstract:
1. An internal combustion engine comprising: at least two cylinders each having a center axis, which are arranged in a “V” to form an angle (α) between the center axes of the cylinders the angle (α) being not equal to zero; two pistons, each of which is mounted so as to slide inside a corresponding cylinder; a crankshaft, which is mounted so as to rotate around a rotation axis and is provided with a crank shape, so as to present, for each piston, a corresponding crank; two connecting rods, each of which presents an end that is hinged to a corresponding piston and an opposite end that is hinged to the corresponding crank; and a first balancing body, which is fixed to the crankshaft in correspondence to a first piston; wherein the arrangement of the first balancing body is such that the first order reciprocating inertial forces generated by the reciprocating motion of the first piston lie along a first straight line (L wherein the combination of the angle (α) between the cylinders with the first inclination angle (β1) is such that the first straight line (L wherein the crank angles of the two cylinders are such that the first order reciprocating inertial forces generated by the reciprocating motion of the first piston are in phase opposition with respect to the first order reciprocating inertial forces generated by the reciprocating motion of the second piston; wherein a third straight line connecting the barycenter (β1) of the first balancing body to the rotation axis of the crankshaft forms a first phase angle (γ1) with the prolongation of a fourth straight line (R
